[harsh matrix]

the AM5N is still on track to return tomorrow

I have no idea if i will have issues with this or not, doesnt seem like i will, but using it with my 7x2 filter wheel may be a pain lol

[tight lodge]

[tight lodge]

so next week the RC will be back in business?

[harsh matrix]

Tomorrow fingers crossed

[frosty shard]

So I've just realized I've been using the NL-Bayes denoising in SIRIL incorrectly. You're supposed to apply it at the linear stage

[tight lodge]

Like with RC astro stuff. You apply NoiseX, BlurX and StarX right at the start of the processing

[vapid patio]

This hurts to spend money

https://cdn.discordapp.com/emojis/1304465186845102100.gif?size=48&animated=true&name=whyvanish

Not even the best camera for the price

@harsh matrix Do you have any trouble doing star collimation with that software? Does the star ever disappear when you barely turn the mirror

Collimation is in my future and I’m not looking forward to it

[harsh matrix]

No

You do need to keep the star as close to good focus as possible while you make adjustments though

Otherwise it can trick you into making unnecessary changes

[frosty shard]

Well I can tell you from experience that if this ever happens, your secondary is loose.

[harsh matrix]

Do not ever touch the center screw btw

[vapid patio]

Ok noted

And it’s like veryyyy small turns?

[vapid patio]

Good to know

[harsh matrix]

yeah

or i will do large turns and the star still stays in the frame

but large turns with metaguide will throw the software for a loop

so small turns for the adjustments you make in that software

[vapid patio]

Noted noted

[harsh matrix]

still debating on 571 or 533 for the RC8 tonight

[vapid patio]

571 duh

With new reducer

[harsh matrix]

it might be clouded out though despite the forecast saying clear yesterday for tonight

[vapid patio]

Sketchy

[harsh matrix]

just cant catch a break

[vapid patio]

Real

When my new guide camera gets here the rc is back in business

I gotta clean the mirrors today and throw it together goodish

Any tips for cleaning

[harsh matrix]

ugh we may indeed be clouded out

wtf man

im so sick of this

[harsh matrix]

uh

dont use a lot of pressure

[vapid patio]

And clean with what? Micro fiber?

[harsh matrix]

if you dont already know what you are doing then look up a guide of some sort

[harsh matrix]

no

people use cotton swabs or Cuiv did a big sketchy and uses his fingers

[vapid patio]

Good idea haha

[vapid patio]

Ok let me see rq

Thanks

[frosty shard]

Kimwipes are also a good option

You can get them off Amazon...I have relatively quick access to them since I work in chemistry

[tight lodge]

@harsh matrix You imaging tonight?

[harsh matrix]

starting to look like a no

[tight lodge]

Clouds rolling in?

I might have a chance tomorrow, but idk what to image. Especially with full moon

[harsh matrix]

yeah

forecast yesterday said clear today

now it does not looks so promising

[tight lodge]

Always when the new gear shows up

[harsh matrix]

Verdict is im not shooting unless by some miracle it stays clear

[harsh matrix]

Almost didnt reach focus with the apex

The weather is not great whatsoever but I think i can squeeze some testing out on the mount

[harsh matrix]

Guys

The Apex-L focuses and i have barely any vignetting

This is with the 571

[harsh matrix]

Holy crap the field is so good after collimating it 😭

This is incredible

I feel like ive unlocked super powers

[harsh matrix]

GUYS

@tight lodge

5 minute Ha sub, with some wind, with the new Apex-L on my 571

full frame

gawd dang this scope is sexy

i love it way more now

[harsh matrix]

here's a not screenshot

[frosty shard]

How's the mount holding up?

[harsh matrix]

like it never acted up

i have admittedly not had a good night of imaging

got 2 5 minute subs in and then clouds the rest of the time so far

it looks like theyre about to break up entirely but with the way the forecast looks, it will probably get bad again when i least expect it

so guiding has been relatively unreliable, however i havent seen any red flags

no bird stars like i would have been getting otherwise

[frosty shard]

Man I really want to get better M16 data. Reprocessed the old data and now I know why the diffraction spikes aren't aligned

(the collimation shifted due to the loose secondary)

[harsh matrix]

you should reshoot that

💯

so far night isnt going great

dumb PHD2 over wrote my min mo's so my guiding has been worse than it otherwise should be simply because it felt like screwing me over

[frosty shard]

Unfortunately we're getting smoked out again

[harsh matrix]

fml

tasty as hell Sii sub

[blissful marlin]

thats crazy

[harsh matrix]

[harsh matrix]

CO modulation in Red

AM5N is fixed

[harsh matrix]

hell yeah

[tight lodge]

How does the Min Mo affect the guiding tho?

Also, what's the RMS range that you usually get. For me is between 0.5 and 0.8, with some beautiful rare exceptions of below 0.4

[harsh matrix]

It can affect the frequency of corrections as well as the strength

I like to keep the corrections neat constant but low in strength since I always polar align with error below 30"

[harsh matrix]

My AM5N has been averaging 0.3" to 0.4" consistently night after night.

[tight lodge]

I know my mount can do the same, is just that PHD2 kinda has a stroke most of the time

[undone sedge]

just realized i could get an RC and do PN hunting if i wanted to
possible..

[tight lodge]

Perfect spot then

[undone sedge]

i'd need to modify it a good bit tho since i'd want to use my heavy 2600 mono train
or a 585 if i really wanted to keep things a little lighter

[harsh matrix]

Surprisingly, with the reducer/flattener, I did not see signs of the "mirror flop".

It would still be a good idea to get the focuser and primary decoupled, but its not as dire as I thought tbh

[undone sedge]

interesting

my main roadblock would just be my seeing here

[harsh matrix]

For sure

[frosty shard]

Lmao same here

I probably shouldn't be shooting at native focal length, but I can't be bothered to figure out backspacing

[tight lodge]

-Bin the sensor to match the seeing-

[vapid patio]

No

[tight lodge]

Yeeeesss

[vapid patio]

Nope

[tight lodge]

Yes

[velvet meteor]

wip but im surprised at how dust free my scope is considering I havent used it in 2 years

[vapid patio]

[vapid patio]

Light leak?

[tight lodge]

Full moon

[velvet meteor]

yea

[vapid patio]

Hm I don't get that on a full moon

I mean look at the stars

[velvet meteor]

i got a 15 minute sub yesterday. Ive never had that ever. but I opted for 8 minutes

[undone sedge]

that being said, the 585 would give me .3” sampling but the rayleigh limit would be ~.46 for an 8” scope

[velvet meteor]

are they slightly oval?

[vapid patio]

They are burnt in. If you look at the image in linear, I bet those stars will still be there.

It’s like if you do too long of an exposure on flame nebula

[velvet meteor]

should the stars be invisible in linear?

or just barely

[vapid patio]

For that target they show a little but they shouldt be like a full on burnt circle

Maybe just overstretched?

[velvet meteor]

this was with the auto histogram stretch

maybe that

[vapid patio]

Oh then, yeah most likely. That’s what it is No big deal

[velvet meteor]

i gotta relearn all this astrolingojargon

i promise i wont abandon my set up ever again.

[tight lodge]

@vapid patio why do you hate binning?

[vapid patio]

not sure

i think it just makes it worse quailty right?

[tight lodge]

no, if your seeing is super bad, binning can actually make a sharper image because you are less oversampled. then you can do a 2x drizzle and get back to where you started

[frosty shard]

Binning increases your SNR per pixel by trading off your total pixel count. In some circumstances it can be worth it (for instance, if shooting a large mosaic that you won't release at native resolution)

[tight lodge]

naah... if i manage to pull the cygnus mozaic, i'll release it at full rez XD

[frosty shard]

I mean if I do that 16 panel of the Andromeda Galaxy, yeah me too lmao

[tight lodge]

The cygnus will be a 900 panel mosaic

[frosty shard]

I was actually thinking about how many panels I'd need to do an LMC mosaic

[tight lodge]

in my case is 225 panels

[frosty shard]

This is 576 panels

[tight lodge]

but in the case of cygnus, i will most likely not spend more than 30s per panel per filter

[tight lodge]

you can get away with 450 panels

[vapid patio]

oh yeah forgot bout drizzling

whats undersampled in your opinion

[tight lodge]

deneb is square

[harsh matrix]

Wanna borrow my RC6 permanently for $500?

[vapid patio]

i use a reducer on my rc6 with my 585

[vapid patio]

huh

[undone sedge]

lol
maybe, let me put some thought into it

[harsh matrix]

Lmao

It's halfway a joke

I need a focuser for my RC8 and ive poached the one from my 6 for the time being.

[undone sedge]

i'd probably upgrade it anyway

[vapid patio]

I’ve seen RC6s for like 300 bucks on cloudy nights

5 is a little steep haha

[tight lodge]

I can't find such good deals here

[harsh matrix]

Well its a carbonstar

I can't quite give it away

These go for more than your run of the mill steel tubes

[harsh matrix]

Btw AM5N averaged 0.4" RMS despite clouds and guide exposures that were too fast for half the night.

It has to be fixed now.

[undone sedge]

🔥

[frosty shard]

What were your guide exposures?

[harsh matrix]

1 second for most of the night, which was too short

I reverted it to the usual 1.5 second guide exposures and then my guiding leveled out and the RMS fell 0.2" lol

It was averaging about 0.7" to 0.6" RMS on the low end until I realized the exposure was probably too short, and thats when I found my min mos were wrong too.

[frosty shard]

You use 1.5 s with an AM5N? Wow

I'm using 0.5 s

Perhaps I should bump mine up and see if that helps

[harsh matrix]

Yes

Cause any shorter gives me horrendous guiding and trailed stars

Something i was dealing with for most of the night last night.

[frosty shard]

I know the usual recommendation for harmonic drive mounts is to keep guide exposures to 1 s and below but I haven't actually done much testing

But at the same time it's not like I have an idea of the periodic error and nonperiodic contributions in the Wave 150i

[harsh matrix]

Thats something you will only figure out on your end through trial and error.

I intentionally didnt listen to the old advice because I could tell it wasnt working with my mount.

The periodic error is too tame and my polar alignment is consistently very very good.

[frosty shard]

I'm going out tonight, not to image but to bring some friends to check out Yanna Research Station, so I'm probably going to use the night to try different guiding settings

The smoke is actually a good thing in this case

[vapid patio]

Ahh ok makes sense

Just lighter?

[frosty shard]

Less thermal expansion too, which means less of a need to refocus

[frosty shard]

I also might have to check up on my collimation

[harsh matrix]

Supposedly

[harsh matrix]

True

[harsh matrix]

Not a bad idea since tonight wont be usable with smoke

You have time to tweak it all night.

Mine lost collimation while it sat around unused, it took a small movement of the secondary to return it lmaoooo

The primary has not moved since I pulled it out of the scope

Beginning of June I believe.

[frosty shard]

Yeah I want to stress test it and see the effect on star SNRs and such

[harsh matrix]

Measure HFR for sure.

[vapid patio]

I mean, I refocus every 30 minutes anyway anyways but yeah

[harsh matrix]

If i used mine more in the native config I could have given you a ballpark number but I havent used it in that configuration at all really

[harsh matrix]

me spit balling to the tech that worked on my mount

a board failure is pretty unusual and it implies some sort of gradual degradation of a component on the board made to hold electric charge

degradation of a component in an unusual way could let electricity arc to other components

or on the worse side of things, and what may have actually occurred, a capacitor which has degraded sufficiently may not hold the charge it was designed for, and may only hold a small fraction of what it was rated for, triggering amplified signals to be sent to the motor drive

[frosty shard]

I found that 1 second exposures are actually just as good as 0.5 second exposures with the Wave 150i, if not better! @tight lodge figured you'd want to know this

Guided at around 0.7" with the 0.5 s exposures, but around 0.6" with the 1 s exposures

The only reason I'm hesitant to say it definitely is better is because we had variable cloud cover during the session (mostly high cirrus)

Not enough to lose guide stars even at 0.5 s, but enough that it made the star SNRs vary a lot

Also, collimation looked fine, the issues seems to be tilt

[tight lodge]

These settings gave me the smallest RMS

[tight lodge]

However it is still inconsistent,

[harsh matrix]

did you try 1.5s exposures?

[tight lodge]

I did, 1.5 is starting to get worse😅

[harsh matrix]

yall keep making me glad i didnt go for the Wave 150i

[tight lodge]

But again... I think is some settings that I have wrong

[tight lodge]

Why you blame the mount?

[harsh matrix]

you might be able to lower the dec aggression and up the min mo unless your PA isnt great regularly

[harsh matrix]

i have yet to see or hear anyone beat the numbers i get lol

plus the clutch issues brandon has with his

[tight lodge]

It guided like this the whole session

[tight lodge]

I tested mine, I have no issues with the clutches. The tripod is the only thing that is not great

[harsh matrix]

wtf

you can put aggression higher than 100?

[tight lodge]

On the RA only

[harsh matrix]

still doesnt beat my record

which was like 0.33" or something

0.31"?

maybe 0.35"?

but does yours average ~0.35" +/- 0.05" repeatedly session after session?

[tight lodge]

That's something that I need to fine-tune in PHD2. Because when I got it, it was bad, now I'm around ~.5" on average, so I'm getting close

[harsh matrix]

heh

mine will average 0.45" at worst in a bad session lmao

it's normally chilling around that 0.35" magical number

[tight lodge]

Plus I haven't really changed too many settings in PHD2 since I got the mount. I mostly played with what's on the screen. No algorithms nothing

||80% of the settings I have no clue what they do||

[harsh matrix]

bruh

you gotta play around with the settings

you might be able to push that mount a lot harder

[tight lodge]

I know... but I don't know what some of the settings do

[harsh matrix]

that's why you experiment

[tight lodge]

That's why I blame myself before the mount. I know that the mount can do it

[harsh matrix]

unless the wave has way more PE than the AM5N, it is worth putting on PPEC as the RA correction algorithm

Hysteresis is fine on the Dec and i think that's what it may already be on for you

another qualifier on that note is that the frequency of the PE will determine how useful PPEC can be.

if it's really big swings in very short amounts of time, PPEC probably wont be of much use, but if it's pretty gradual, it should be no problem

@frosty shard listen up

[tight lodge]

Also I the guide speed... I've seen some stuff about reducing it to 0.5 instead of 0.75

[harsh matrix]

Thats another thing you need to experiment with to figure out.

[tight lodge]

Yeah... only if the skies will cooperate with me

[tight lodge]

Also, I'd love to experiment with it, but considering that at the moment I have about 2h of astro twilight, I just risk it and image in this state😅

[vapid patio]

0.5 for the win

[frosty shard]

Can you select hysteresis for the Dec axis? I thought it was just resist switch, lowpass(2) and Z-filter?

[frosty shard]

Since I swapped the hand pins for M6x12 bolts I have had zero issues

I didn't try PPEC for RA but I definitely should, and I didn't try 1.5 sec exposures

[harsh matrix]

Yeah

[vapid patio]

Turns out I had my reducer backspacing wrong

It was 70mm not 80

[harsh matrix]

[vapid patio]

huh what

[harsh matrix]

I thought that was intentional lmao

[vapid patio]

less reduction?

[harsh matrix]

The more backspacing you add, the more reduction you get

[vapid patio]

✅

[harsh matrix]

I thought you did that because you wanted more than 0.67x reduction

[vapid patio]

to get 0.67 it is 80mm of spacing, i had tried originally to get more but could NOT reach focus so i just went to spec. but actually went to 70mm not 80

so im at 80 now all good ✅

[harsh matrix]

Oh hang on

The way you worded that is what made me HUH

Because I thought the 0.67x reduction was 80mm but you said "It was 70mm not 80mm" so you made it sound like the proper reduction was less not more

Thats why.

[vapid patio]

@harsh matrix whoops haha my bad. but so yeah im not at 80mm of spacing and go from 1370 to 911mm

is it worth to push to 90mm and become f/5.6 and 854mm?

[harsh matrix]

Are you still having issues with consistent guiding?

[vapid patio]

no let me explain. once we dialed in my settings the limiting factor was now my asi120mms ability to see stars "as now we are doing 0.5s exps" so i ordered a new guide cam "asi220mm all I can get right now" to give me good guiding

[harsh matrix]

Got it.

Id say get your 220 first and try 80 mm back space

If by some unfortunate luck, you still have trouble getting guide stars, then go to 90 mm of back space

[vapid patio]

ok bet thanks

[tight lodge]

Have you increased the gain of your camera?

[vapid patio]

too much and the stars become noise

im barely scraping by 🙏

[tight lodge]

Pay to win brother

[vapid patio]

Exactly

So I bought a new guide camera

[tight lodge]

By any chance, was there a telescope attached to that camera

[harsh matrix]

https://app.astrobin.com/i/p9cmwy?r=C

Revision 3 baybee

[frosty shard]

The edge of the honse is so sharp you could cut glass with it

[tight lodge]

Ok... I got a question for you Vel. How do you map a channel to orange or... purple?

[harsh matrix]

it is fr

[harsh matrix]

i used a combine images script made for JWST images to do it in Pixinsight

you could achieve the same outcome by manually mapping colors to each filter in photoshop or gimp though

i just have a massive skill issue and i cant get it to work out the way i want in either of those

[harsh matrix]

RC8 shenanigans again

i added the last bit of data from the other night to my existing 50 minutes

the signal was a bit worse due to poor transparency and eventually clouds, but it didnt affect the existing data too badly

[tight lodge]

You should imagine some SII as well.

The SII looks really cool on the pillars

[harsh matrix]

i did

only 20 minutes survived the night

the rest was garbage

same case for all channels though tbh

[tight lodge]

I do have some SII that I could share, but I doubt it's up to your expectations

[harsh matrix]

mine is pretty garbage lol

[tight lodge]

When I'll get home tonight, I will share the SII

[frosty shard]

Trashed all my Lagoon data

No idea why the focus was so far off

Check out this CO modulation though

[harsh matrix]

NOOOOOOOOOOOO

[harsh matrix]

YEAAAAAHHHH BWOIIIII

that's some CO mod

[frosty shard]

Funny enough, that was the last sub I took before the Lagoon subs, and all of them were out of focus

Tonight was not good for imaging though, fog rolled in

so I didn't waste too much imaging time

[harsh matrix]

rip man

just cant win right now

[frosty shard]

I got some more data on the Crescent though, processing that right now

[frosty shard]

Alright this is not good

All my stars are elongated, and I think it's all due to guiding issues

I noticed, weirdly enough, my RA corrections were very sluggish and would not move the mount very much at all

By contrast Dec was totally fine

[harsh matrix]

this looks like RA error too

uh oh

[frosty shard]

Yeah it lines up perfectly

[frosty shard]

Got any idea what might be going on?

I will note, it was not a good night for imaging due to fog, but I never lost guide stars at any point during the night or had PHD2 complain about guiding

But I did have the whole "guiding may be impaired" due to orthogonality error

[harsh matrix]

Hmmmm

How far off was the RA and the Dec from being 90 degrees?

And did you have any cable snags?

[frosty shard]

11 to 15 degrees depending on the run

[frosty shard]

I didn't check for this actually

[harsh matrix]

Okay that should be manageable under ideal circumstances

[harsh matrix]

The other thing it could be is that maybe you didnt have the aggression on the RA high enough or didnt have the min mo low enough

Or the maximum pulse size you allowed was too short

Those could all be factors and all of them revolve around exposure time too

[frosty shard]

My minmo was 0.5, aggression was 80, and I was actually just using half second exposures. In the past I've used these settings without serious issues

[harsh matrix]

You have the Xena-M right?

[frosty shard]

Yup

[harsh matrix]

Drop that min mo way down

Do like 0.2 or lower

That is most likely why you are having issues

[frosty shard]

Do you have them both that low or just RA?

[harsh matrix]

My RA is actually 0.16 rn

For min mo

The Dec is at 0.28

Wait wrong

Correction, that is right

[frosty shard]

The guiding assistant at one point told me to move minmo up to 1.5 which seemed very wrong

[harsh matrix]

If the min mo settings you are using is from guiding assistant, dont listen to it

It's not good at giving you settings for a harmonic mount

It will get the job done but it will not yield results good enough for high focal length imaging

[frosty shard]

I bumped it up from the baseline 0.3 or whatever the default was because I assumed that it needed to be increased, but I'll move both down

[harsh matrix]

Yeah if the RA and Dec responses are sluggish, you can adjust the min mo down to compensate

It's better to have constant small adjustments than few large adjustments with these harmonics

Thats how you get the most out of them

Since you have the Xena-M too, the min mo's need to be quite a bit smaller than if you had any other guide cameras since the pixels are huge

From my understanding, the min mo defines how many pixels, or how many fractions of a pixel the mount will be allowed to drift before PHD2 issues a correction

[frosty shard]

I found it weird that the RA was so sluggish, it was almost like it couldn't clear backlash but there just isn't any

[harsh matrix]

It could be that the clutch came loose again but I sort of doubt it

You seem to keep that on a tight leash

[frosty shard]

I highly doubt it, since the mod I've never had any issues

Also that would show up in Dec most likely

the stock bolt for the RA clutch is very secure

[harsh matrix]

Interesting...

So yeah I suspect dropping the min mos will help with that.

0.5 is extremely high

I dont get good images if my min mo on RA is above 0.2

[frosty shard]

Yeah I'll just set RA to 0.2 and Dec to 0.25 and go from there

[harsh matrix]

Cool

And if you think the RA is still responding too slow, and your RMS remains pretty high, you can drop the min mo further

I think ive gone as low as 0.13 on my AM5N

And like 0.08 on my EQM35

[frosty shard]

Maybe that'll need to be slightly larger to compensate for the fact that I'm not using the reducer, but if you're going that low I'm just gonna start at those numbers

The guiding actually seemed really good until I looked the subs; the only indication was the poor RA response

[harsh matrix]

Actually I dont change the min mo between my scopes

The reason being is that performance remains the same

[frosty shard]

0.5" or less for most of the night

[harsh matrix]

It's because its measuring in fractions of a pixel, and not in arc seconds

[harsh matrix]

Weird

Oh god

What if its flexture?

[frosty shard]

I hope it's just a poor choice of settings, but what could be flexing...

Maybe I should check my OAG screws actually now that you say that

[harsh matrix]

That

And check the guide camera itself to see if it came loose somehow

Maybe see if the focuser is threaded on tight too.

[frosty shard]

Focuser was definitely threaded on correctly, I check the configuration for flexure all the time, but I haven't checked on the OAG screws

[harsh matrix]

Ight

[frosty shard]

Excellent call. The screws holding the prism in place did come loose

[harsh matrix]

Oh fuq

[frosty shard]

not by very much but enough to notice

[harsh matrix]

Lol well maybe that will fix it

[frosty shard]

Well I've got several things to test but hopefully that covers it all

[harsh matrix]

Btw how long were those subs?

[tight lodge]

Bro, PHD2 has no clue that is guiding a harmonic mount. Guiding assistant even freaks out that it can't measure backlash

[frosty shard]

180 s for everything

[harsh matrix]

Were all of the subs equally elongated?

Or was it variable?

[frosty shard]

It seems to vary a little bit

But not enough that I ever had a sub with round stars

[tight lodge]

@harsh matrix ! Here's the SII data. It ain't the best, but it's better than nothing 😅

[harsh matrix]

Could very well be flexture and/or bad settings

[harsh matrix]

[tight lodge]

Is that a good sniff or a bad sniff?

[harsh matrix]

We will see later tonight lol

[tight lodge]

It ain't much, but it's honest work😂

[harsh matrix]

@vapid patio they're someone who came along to troll in Astronium

QQQ timed her out last night

No kicked her

[vapid patio]

ah i see i was talking to her last night a little odd...

[harsh matrix]

And then QQQ gave me permission to ban if she came back within 24 hours

[vapid patio]

you should ban lowkey nothing good come from this tbh

[harsh matrix]

Yeah she's resorted to weird half bait rage baiting spam

[harsh matrix]

I just did

[vapid patio]

lol

[vapid patio]

good

[harsh matrix]

Thats why she's back here trying to bring drama here

I banned the friend too but QQQ unbanned him and put him on strict watch for arguing all of the time

I told QQQ he would keep doing that too and he didnt listen, next thing you know he's part of a huge argument yesterday, the same day he was unbanned.

💀

[vapid patio]

come on 😭

@harsh matrix how much should i sell my 5x2 filter wheel for/ im getting a 7x2

im thinking 250?

[harsh matrix]

Start at 250 and drop it to 200 if it goes too long without any offers.

[vapid patio]

BET TOO EASY

sorry for caps

[harsh matrix]

bruh

[vapid patio]

How so

[harsh matrix]

imma delete once you read

[vapid patio]

Missed it whoops

[harsh matrix]

BRUH

[vapid patio]

Haha 😅

Well well well

[harsh matrix]

[vapid patio]

What a weird person

Respectfully

[harsh matrix]

Honestly he just seems to be jealous that I have friends online and he doesnt

Thats what it started to lean towards.

[vapid patio]

So odd

And he was all up on you like chill 😭

[harsh matrix]

Yeah

He seemed to hate me mostly for how I spoke

[vapid patio]

Y'all were in a vc at one point?

[harsh matrix]

No

It's how I worded my messages that he didnt like

[vapid patio]

Oh not spoke then 😭

But anyways weird

[tight lodge]

Did someone say... Drama?

[harsh matrix]

Sort of

[tight lodge]

Discord drama is always fun

[harsh matrix]

It's so unnecessarily stupid too

[tight lodge]

Watching a bunch of grown-ups acting like the 12 it's kinda funny

[harsh matrix]

These 2 were just kids though

So it wasnt any fun to watch

Just annoying to deal with.

[tight lodge]

Uuuhhh

[tight lodge]

I bet. A good advice... just don't give them attention, they'll get bored and leave

[harsh matrix]

They're banned now because they just kept causing trouble for everyone else

Not just the mod team

[tight lodge]

@frosty shard those CO modulation rings might give you an insight of what could be weird about the optics.

[frosty shard]

I don't think anything's wrong with my optics as far as I can tell?

[tight lodge]

Something has to create that notch in the rings

[frosty shard]

Someone took a stab at my data

[vapid patio]

i get them too

some reason i didnt get them on my osc camera but show alot with my mono cam

[blissful marlin]

@harsh matrix you like my new nickname?

[harsh matrix]

Yes

[harsh matrix]

The decoupler mod from Natemandoo on CN is 500 dollars for an anodized version, and 400 for bare aluminum.

[vapid patio]

@harsh matrix No way I just sold my efw for 260 😭 I bought it for 200 this hobby is profitable

Stupid PayPal took 5 bucks

[harsh matrix]

What the

That person is probably dumb

Unless you got yours used

[vapid patio]

Yep

I'm second owner

[harsh matrix]

LOL

Thats funny

[vapid patio]

Now I’m gonna look for a seven position finally I’m a real astronomer

@harsh matrix HAHAHAHAHAAH LOOOK LOOK

225 😭

[undone sedge]

yoink a 7x2" instead
trust

it'll save you from upgrading in the future

or a 7x36mm

smthn

[vapid patio]

yep thats what im going for now

i already have my lrgbsho filters

[harsh matrix]

He can get a 8x1.25" rn and then upgrade the roulette down the road too

Lots of options

But a 7x36mm makes the most sense

[vapid patio]

i have all 2" filters

[harsh matrix]

Oh so you're sticking to 2"?

[vapid patio]

i mean why not

[undone sedge]

wish i got 36mm when i was building out my primary rig
would make 3nm filters so much cheaper 💔

[vapid patio]

plan to get a 571

[harsh matrix]

W

[harsh matrix]

Rip

[vapid patio]

is player one shipping again?

cant tell

[undone sedge]

i think so

for now™

[vapid patio]

i might wanna get player one efw for 320

WAIT 300 FOR 7X2???

[harsh matrix]

Ig?

[vapid patio]

huh

[harsh matrix]

I thought it was more

[vapid patio]

player one aslways has good prices

but stupid china wont talk with us so we STILL GET NO PLAYER ONE

[harsh matrix]

The astigmatism in the primary due to flexture is showing real bad at 33 degrees altitude lol

[vapid patio]

Whatever guess I'm getting zwo one

[harsh matrix]

I guess I need a decoupler

[harsh matrix]

Yeaaaaaah

0.48" RMS guiding and first Ha sub has blob stars

But at the start of the session before PA, the stars were out of focus and the primary was very obviously collimated well

The field looked excellent until I slewed to Eagle lol

Also the blobs were in the direction of what would be Dec error i believe, not RA

And the dec is chill

[harsh matrix]

Now that M16 is near the meridian the stars look perfect

This is why i dont rush to redo collimation when I see oddities

This stupid design flaw is why.

[harsh matrix]

Crazy CO modulation

[vapid patio]

Why?

[harsh matrix]

The FWHM of the frame i looked at here was 2.25" iirc

So the almost complete lack of atmospheric blur emphasized the rings further

[tight lodge]

@harsh matrix i played with Pix's color mapper and I made red blob

[harsh matrix]

Lol

[vapid patio]

Power of Texas I guess

[harsh matrix]

LOL

Tonight will be even better

The seeing is forecasted to be above average

[vapid patio]

Have fun

All my gear is getting here anyways

220mm and 7x2 filter wheel

[harsh matrix]

rip

Open im browser

But uh, raw image, I just linear fit, applied the stf stretch, and did curves

Very bad BGE

[harsh matrix]

West Veil Neb too

[vapid patio]

How long

[harsh matrix]

35 minutes of Ha and 30 minutes of Oiii

[vapid patio]

Ok not much sick looks sharp

[harsh matrix]

Looks better than 17 hours with my modded DSLR

[vapid patio]

Haha I would hope

You ever take a look at my data?

[harsh matrix]

Oh crap no i didnt

I forgot

[harsh matrix]

Exactly

[vapid patio]

Yeah no worries if you ever wanna that be cool

[vapid patio]

How much are you planning?

[harsh matrix]

Idk I'll see how much I have at the end of this M16 project

[vapid patio]

Ohhh yeah yeah

[harsh matrix]

Im filling in the remainder of the night with the west veil

Idk how many times it'll go into my tree though so I might end up deleting half my frames each night

[vapid patio]

You are useing 571 on rc8? What reduction?

[harsh matrix]

Yes

At 0.65x

F/5.12

Basically an f/5 8" newt without the coma

[vapid patio]

Ahh man I feel you

[vapid patio]

A 65 reduction? Is that the recommended reduction?

[harsh matrix]

Thats what the Apex-L is designed to function at

[vapid patio]

Reducers on rcs ngl are overpowered

[vapid patio]

Dang fancy

[harsh matrix]

Yeah exactly lmao

This reducer doesnt have any glaring flaws

It's a reducer/flattener too so there is no field curvature

[vapid patio]

Mines only f/6 smh smh

[harsh matrix]

Only the artifacts at the edges do to actual field errors from the scope.

[harsh matrix]

Ik

[vapid patio]

Dang well that's fancy

[harsh matrix]

Thats why you have to get an 8" hehe

The 8" RC's and bigger are OP

[vapid patio]

Can't with my super small sensor even with reducer is no good

Gotta get bigger sensor first but Ima enjoy my 585 for a little

[harsh matrix]

True ish

[vapid patio]

If you ever upgrade to 10” let me know

[vapid patio]

How ish? Don't forget my mount

[harsh matrix]

LOL

I may in a few years but id probably keep my 8" to have a "widefield" light bucket

Especially if I get the decoupler mod

[vapid patio]

The difference

[vapid patio]

Decoupler?

[harsh matrix]

Yeah to separate the focuser from the primary mirror to fix that astigmatism i was talking about last night

Not seeing it tonight though

[vapid patio]

You mean like an extension ring?

[harsh matrix]

Nope

[vapid patio]

Interesting

[vapid patio]

Bipolar

[harsh matrix]

https://www.cloudynights.com/topic/827768-finally-made-an-rc-collimation-adapter/?hl= rc mirror decouple

This

[vapid patio]

I found one you can 3-D print

[harsh matrix]

The focuser is hooked directly to the collimation mechanism that controls the position of the primary mirror, so all weight on your focuser gets transmitted straight into the primary mirror, causing flexture, which presents as unfixable astigmatism.

[harsh matrix]

Won't be rigid enough

Tbh

Needs to be solid aluminum or steel, something with no give

[vapid patio]

Depends on what material you use but yeah

[vapid patio]

Fair fair

Oh interesting does it only really happen when you’re pointing stright upish?

[harsh matrix]

No

Happens most at extreme right ascension and declination angles

It was happening really bad last night with M16, at 30 degrees

[vapid patio]

Hmmm interesting

[harsh matrix]

But didnt tonight

Fraken weird scope

[vapid patio]

I’m guessing maybe the temperature plays a role?

[harsh matrix]

No idea

Conditions are pretty much identical

[vapid patio]

Odd but if it works it works

Can I see a photo?

[harsh matrix]

Of what?

[vapid patio]

You said you’re imaging tonight

[harsh matrix]

I am but I dont have any way to show tonight's progress on hand atm

[vapid patio]

Alright all good

[harsh matrix]

I do have a raw version of last night's data right here though

Tonight's is like this but sharper, by quite a bit. Lol.

[vapid patio]

Wow that's sick well once you get that data all together maybe send over the master?

Oh also question. Do you dither?

[harsh matrix]

Every loop of frames yes

[harsh matrix]

Sure

[vapid patio]

After how many frames? Leta say your doing 300s

[harsh matrix]

If im doing SHO, I dither every 3 frames

At 300s

If im doing just one 300s frame, every frame

[vapid patio]

[vapid patio]

Good to know good to know

[harsh matrix]

Every single 180s frame of one filter is every 2

But I will dither once in an RGB cycle for 3 180s back to back, 1 for each filter.

[vapid patio]

what do you think of people who sink there camera as cool as it can go always to get no hot pixels

[vapid patio]

Ok yeah

[harsh matrix]

I think they're crazy

I dont want to burn out the cooler

[vapid patio]

Same thought

🤝

[harsh matrix]

Will dither once for a full cycle of 1 R, G, and B frame.

[vapid patio]

Ok yeah same as sho. Pretty much every color image sorta

[harsh matrix]

Yes

You will only see walking noise develop if you are not dithering for extended periods of time with mono

As long as you are dithering like once almost every 10 minutes you're good.

[vapid patio]

Cool thanks for the info I will change some settings around

Oh also I have a good question

[harsh matrix]

Yeah?

[vapid patio]

Mr pickles says if your seeing is bad you should bin your sensor then drizzle it back?

My seeing is always bad so maybe it's a good idea?

[harsh matrix]

I have no idea

[vapid patio]

https://cdn.discordapp.com/emojis/1304465186845102100.gif?size=48&animated=true&name=whyvanish

[harsh matrix]

Since you're shooting reduced, your sampling will be a bit more ideal.

It might be worth a shot though

[vapid patio]

Its around .80 ish

[harsh matrix]

What's your FWHM in arc seconds normally?

[vapid patio]

.65 sorry

[vapid patio]

Might be dumb but I have to see it in pix right?

[harsh matrix]

Yeah

Do an image analysis on it in Pix, take the FWHM in pixels and multiply it by your sampling

Image analysis is a script

[vapid patio]

Ok yeah yeah mb I don't know haven't gotten any real data with the sensor only star trailed images

[harsh matrix]

[vapid patio]

I only have that crescent data

[harsh matrix]

You can check that data lol

[vapid patio]

But the trails right? It changes my stars fwhm? No? Maybe I have it all wrong

[harsh matrix]

Oh the trails will yes

[vapid patio]

And I said that.. Only data I got

[harsh matrix]

Well crap...

[harsh matrix]

@vapid patio there you go

1.85 HFR

on Ha

i need to not be lazy one of these nights and actually redo the offsets or verify that they are correct just to be safe

curiously the astigmatism seems to have returned now but on the opposite side of the pier as last night

wack

[harsh matrix]

okay guys got a pseudo collab between Rubolo, @tight lodge , and I on Eagle

[tight lodge]

https://www.astroshop.eu/Produktdownloads/53809_1_EN_Omegon_Ritchey_Chretien_Full_Tube_IM_REV_C.pdf
@harsh matrix Will this be a good choice?

[tight lodge]

Ngl... I'm kinda like this everytime I look at it

[vapid patio]

Wowowo

[vapid patio]

Woo

Woooo

Finally 😭

[harsh matrix]

Yeah that looks good

[tight lodge]

Awesome... Now I have to get the perfect opportunity to get it. Maybe Elon Muskular will lend me some money

[tight lodge]

@harsh matrix is this going the right way?

on the left is totally different processing and on the right is the old process that i did a while ago

[harsh matrix]

Id say the right side is a lot better yes

You are getting that look to it

[tight lodge]

right side? . Right side i thought is the bad one XD

well... back to it i guess

[harsh matrix]

O

The left is more accurate to the colors I go for when trying Euclid

But the luminance of the stars looks messed up

[tight lodge]

that's what i'm trying to do. both have some NIR data. not enough tho. It's all i have to work with unfortunately.

[tight lodge]

i'm not focused on the stars. i was too lazy to run StarX so i'm trying to just go for the colors

[harsh matrix]

I should have said the luminance of the overall image looks off

It's out of wack

[tight lodge]

i decided to tone down the purple as well

[frosty shard]

https://agenaastro.com/qhy-minicam8-camera-ariii-argon-iii-filter.html?rfsn=7382606.9c913c

Holy crap

Hey Touptek, make me an Ar-III filter

[harsh matrix]

Yup

[harsh matrix]

Is this 2 or 3 channels and is it an STF?

[tight lodge]

2 channels, and no, it's not STF

[harsh matrix]

Hmmmm

Maybe its the way you stretched it

[tight lodge]

Most likely

[frosty shard]

Alright everyone, I need a new tripod

Last night mine started falling apart

[harsh matrix]

Already?

[frosty shard]

Yup. Seems like it can't handle the dew/condensation

The adhesives, that is

Honestly I could be doing a much better job drying off the tripod but I wouldn't expect the adhesives to just fall apart the way they have

[harsh matrix]

Exactly

Is the tripod the carbon fiber one from skywatcher

[frosty shard]

Yup

[harsh matrix]

Ah

Yeah skywatchers quality isnt very good

[frosty shard]

Ideally I'd like a taller one that doesn't weigh too much more

Honestly I shouldn't have bought that tripod. I should have bought the Apertura one instead

On a related note, I'm starting to think the Dec clutch issue isn't a problem with the mount, but the stock pins

Because I haven't had any issues with Dec play after replacing them

[frosty shard]

https://www.wis-tns.org/object/2025rbs

New supernova in Caldwell 30/NGC 7331 in the Deer Lick group

[undone sedge]

part of me really wants to try shooting some of campbell's hydrogen star on the 24" cdk buuut our seeing is probably gonna give me the middle finger on that idea

if one of y'all wants to undertake it with good seeing & a small pixel scale do ping me with the results

if i tried doing it with my scope it'd be only 7 pixels across so

[harsh matrix]

Yup

[vapid patio]

Wait thoses colors are sick

What do you mix it with?

[harsh matrix]

I had no idea M42 would have argon emissions

[frosty shard]

There was an attempt

[harsh matrix]

could be much worse

gonna try to shoot that supernova tonight

[frosty shard]

Not the best data but I like how I got the colors to turn out

[pine path]

Hey we discovered this

[tight lodge]

[tight lodge]

Well I need your help then

[pine path]

with supernova or just in general?

[tight lodge]

Yes... well, I think it's a supernova. It's just weird that it shows up in 2 very specific filters and others friends that imaged the area got similar results #1386583050703605933

[harsh matrix]

caldwell 30 is upside down here but the dot offset from the nucleus is the supernova right?

[tight lodge]

Ye

[harsh matrix]

helllllll yes

it's brighter than the nucleus holy

i wonder what kind it is

[pine path]

Type Ia

Which are brighter than most core collapse supernovae

[harsh matrix]

it is a type 1a then huh

cool

[vapid patio]

I had a nightmare last night

I bought a coma correcter

[tight lodge]

That's a bad dream, not a nightmare

[pine path]

Yep! Some white dwarf in C30 had a very bad day. This is before the supernova, our discovery image, and then our most recent image

Barely visible in the discovery image lol but that's why we have difference imaging

[harsh matrix]

i can see it

hell yeah

[vapid patio]

Are coma correcters even expensive

[tight lodge]

Some of them are.
But let me show you nightmare fuel
This is nightmare fuel

[vapid patio]

https://tenor.com/view/ash-baby-gif-5920695394641505768

[vapid patio]

Scary

[pine path]

Oiii emission wouldn't make sense for a supernova, or most kinds of transient tbf. I think the Oiii IR leak is probably the best explanation but maybe something else funky going on there

The Oiii line that we image is a forbiden emission line, so you typically only see it in fairly low-density gas. Supernova interactions do produce narrow emission lines but usually hydrogen (by far the strongest) and He II

Those images do look very odd though

[tight lodge]

With the OIII IR leakage i uderstand, but then, whatever that is, it's also very bright in IR

[pine path]

Mira variables are very very red so that makes sense

Looking at V1360 Cyg it's maxmimum V-band magnitude is about mag 13 (and the light curve looks like a mira), but in the infrared I band it's mag 9, and going deeper to K band it's magnitude 4

so these things are much brighter in the IR

[tight lodge]

that would make sense why they pop out so bright

that means i got 3 bright Variable Mira stars in the Tulip Nebula

[pine path]

As long as they show some variability then that's quite likely, though there are other types of variable red stars with slight differences

[tight lodge]

well... i do not really have the tools to properly measure them

[harsh matrix]

@frosty shard I may be able to grab an hour of M24 blue for you

Tomorrow or monday

I think i may run to the bortle 3 site

[vapid patio]

finally actually got a goodish result i like in this hoo for ngc7000

need to fix those stars rq

[tight lodge]

Holy sharpness. You've been cooking while you were quiet

[harsh matrix]

pushing the limits of what is possible with a consumer RC

[frosty shard]

...did you do a mosaic

I don't think "cooking" is sufficient to describe this

[harsh matrix]

no

project aint even close to done yet

OH SHOOT WTF

[frosty shard]

Another paper refutes this and says that they should be around for much longer

[frosty shard]

is the wide field from your RedCat?

[harsh matrix]

no

[harsh matrix]

uh oh

[harsh matrix]

You do see the diffraction spikes right?

As well as the CO modulation?

[frosty shard]

I am insanely sleep deprived atm lol

Now I see it

[harsh matrix]

Are you out in bortle -12 again?

[frosty shard]

Nah just rudely awakened this morning from an unexpected lightning strike and trying to prepare for a conference

[harsh matrix]

[vapid patio]

hehe what can i say

[vapid patio]

[vapid patio]

@harsh matrix Its in Texas amazing deal

[harsh matrix]

Oh balls, thats a steal

[vapid patio]

i know like maybe worth just going and reselling it on cn for alot more

[harsh matrix]

First sub is crazy

[vapid patio]

fany fancy

windy tonight?

[tight lodge]

@harsh matrix Are there any accessories to look for when getting my first RC?

I see lots of extension tubes and I have no idea if I need em or not

[harsh matrix]

Not very

[harsh matrix]

You don't need them

Should come with enough

@frosty shard just saw NGC 7331 and Stephan's Quintet.

With me dob

[frosty shard]

Did you spot the supernova?

[harsh matrix]

Pretty sure i did

The core of the galaxy shouldn't look like a bright defined dot, but there's definitely a bright defined dot within the buldge.

Was going to shoot NGC 206 with the RC8 while im out here but I decided to shoot the Supernova since thats on a timer, and its brand new at present.

[tight lodge]

In so close to biting the bullet on the RC

[oblique sun]

I thought you already had an rc8

[harsh matrix]

Nope

[harsh matrix]

Hehe

I hope it has nothing to do with me sharing this

[tight lodge]

Naah.... not at all

But for real? I always wanted an RC, and seeing my data togheder with yours plus all these images that you keep popping around just acted like a catalyst to finally get one.

[harsh matrix]

Deer Lick group and Stephan's Quintet. A single 3 minute lum sub.

[tight lodge]

See? Why you ask, "Am I responsible for you wanting an RC?"

[tight lodge]

Your phone has a lot of spherical aberration

[harsh matrix]

Got a lot more than that going on

This is why phone AP didnt work out

[harsh matrix]

[tight lodge]

There goes my plan for more ink

[harsh matrix]

I can see the flex induced astigmatism clearly here

Fortunately the seeing is bad enough to mask it

[tight lodge]

Bin the sensor to make sure nobody will notice

[harsh matrix]

Nah

Though that would go hard here

It would be exponentially more signal

[tight lodge]

See?

Try a single Bin 2x2 and see the difference. If the seeing is bad that might actually help you avoid oversampling

[vapid patio]

[harsh matrix]

Im actually not convinced the seeing was bad enough to justify doing that

Maybe if I bring it here in the future and the stars are like 5 pixels wide when the scope is in focus, I will give it a go

[harsh matrix]

[undone sedge]

holy hot pixel

lookin schnazzy

[harsh matrix]

yeah

cause of hot nights here

the temps are higher here than back at home

[undone sedge]

damn

[harsh matrix]

the camera isnt too happy here

[undone sedge]

what was your cooler at?

[harsh matrix]

-5C

[undone sedge]

ah

[harsh matrix]

it was at around 75% power

[undone sedge]

i’ve been somehow managing -10°C, barely
my cooler is at around 95% most nights

[harsh matrix]

yikes

i cant do that here or at home

[undone sedge]

next summer i’ll probably give it a break and do -5°c though

[harsh matrix]

temps stay too high at night and once the typical summer cycle hits, it will probably be even harder

[harsh matrix]

1 3 minute sub per channel

on the bright side, if my flats dont end up working, i may not need them

i just have to calibrate the bias out and it will be usable data

ill need an MSGR ref for NGC 7331 to Stephan's Quintet, and Trifid

pretty sure NGC 7331 to Stephan's has MARS data now

not sure about Trifid

[tight lodge]

I think it has. The community submitted

[harsh matrix]

I hope so

[tight lodge]

I mean, Rho is covered, so Trifid should be as well

[harsh matrix]

Ill be using MGC regardless of if my flats work or not as id like to preserve everything I captured.

[vapid patio]

Heheheheh I’m getting a Juwei 17

Have you seen those before @tight lodge

It’s a knock off am5

And I’m getting it and a tc40 tripod/extension for free 🤑🤑🤑

[tight lodge]

I heard about them from our lord Cuiv the lazy geek

[frosty shard]

yo how are people getting free tripods when I'm the one who actually needs one lmao

[tight lodge]

Sign me up for one. CF tripods suck

[frosty shard]

I'm debating whether or not I should get a heavier tripod

[tight lodge]

Steel tripods for life. Imma get the pier extension that can adapt to the HEQ5 tripod

[frosty shard]

I have to weigh in my unusual transporation needs with my rig

[tight lodge]

How long until you get your driving license?

[harsh matrix]

so the dew shield around the secondary mirror is basically useless if you are in an incredibly humid environment

i walked outside to look at my gear this morning to find it completely drenched in dew

looked down the tube, the primary looked foggy, the secondary was completely soaked, and it looks like it dewed up so bad that the last 12 or so minutes of the night are useless, AT LEAST.

havent been able to look at the data yet, but i dont have high hopes for NGC 7331, may need to go back tomorrow

[harsh matrix]

crap the meridian flip is what screwed up

well i only lost a few frames per channel

ill see what i get

[harsh matrix]

WOW

my data is sharper than telescope live data, across the whole field anyway

sharpness is consistent

the field is flat

this RC is fantastic

[vapid patio]

I don’t think he made a video about one

[vapid patio]

I have rich Astro friend 😅

[frosty shard]

Probably after I graduate from grad school early next year. Well I have a license I just don't have a car

[harsh matrix]

btw @frosty shard I looked at the trifid the last 2 nights

with the dob

looked a hell of a lot like this

[frosty shard]

That's a great target for visual

Did you have a filter?

[harsh matrix]

Yes

The filter made it possible to make out the bands ever so slightly

[undone sedge]

which filter was it?

[frosty shard]

H-beta is recommended for the Trifid IIRC

I've found that O-III works too

[harsh matrix]

aaaand there it is

SN2025rbs

[undone sedge]

hawt

[harsh matrix]

real

me when my flats work better than any calibration that telecope live does

[vapid patio]

Telescope live?

[harsh matrix]

An online service that provides data in turn for payment.

[vapid patio]

Oh wait yeah yeah like you can rent a big scope

[harsh matrix]

Sort of

The data is almost always dodgy in some capacity

[vapid patio]

lol yeagh

my new mount gets here tomorrow

[harsh matrix]

What you doing with the AVX?

Did you sell it?

[vapid patio]

avx? hahaha cgem

[vapid patio]

no i have a friend that is pretty much giving me a Juwei 17 tc40 tripod and pier extension so ready to go

pretty much a knock off am5

same performance, has a slower slew speed. but totally upgradable

[harsh matrix]

O

[harsh matrix]

Astro hax

That'll solve a lot of problems at once

[vapid patio]

I KNOW RIGHT

[harsh matrix]

It'll make a bunch of problems too.

[vapid patio]

how

so

[harsh matrix]

Now you gotta figure out how to tune the guiding

[vapid patio]

pretty normal?

[harsh matrix]

It's nothing like guiding a GEM

[vapid patio]

uh oh

dont you have am5

[harsh matrix]

The guiding assistant doesnt give you sufficient settings

[harsh matrix]

AM5N

[vapid patio]

huh?

[vapid patio]

perfect then enlighten me

[harsh matrix]

Basically very low min mo's and fairly low maximum pulse lengths are the name of the game

RA correction algorithm is PPEC and Dec is Hysteresis

[vapid patio]

[harsh matrix]

Min mo's im talking are like 0.16 on the high end for RA, and 0.28 as a good starting point on the dec

[vapid patio]

oh ok light work

[harsh matrix]

Maximum pulse length on RA for me is 350

[vapid patio]

my cgems is 0.08 lmao

[harsh matrix]

Setting it higher makes PHD2 guide unnecessarily poorly

[vapid patio]
