Astrophotography, also known as astronomical imaging, is the photography or imaging of astronomical objects, celestial events, or areas of the night sky. The first photograph of an astronomical object (the Moon) was taken in 1839, but it was not until the late 19th century that advances in technology allowed for detailed stellar photography. Bes...

@frosty shard the RC might be find

#

It just doesnt play nice with such a big sensor.

#

Im not seeing the same artifact severity with the 533 as with the 571.

#

I can probably use the reducer too.

tall summit
harsh matrix
#

It will be more than adequate for a 533

tall summit
#

sorry, thought you meant with 571. that sensor size worked out great for me

versed roost
tall summit
versed roost
#

whos RC design lol

tall summit
#

everyone's?): in general

tight lodge
frosty shard
#

So an APS-C sensor should be fully illuminated with the reducer

harsh matrix
#

Since the ring of illumination that was present in the 571 is not present in the 533

frosty shard
harsh matrix
#

I could give it a shot in a moment however...

#

The problem in the 571 flats looks a suspicious amount like a baffle tube that is too short.

#

And I have no idea why that would manifest on a 571 sensor and not a 533

harsh matrix
#

I got excellent flat calibration on my M78 and Boogeyman data from bortle 3

#

I used the 571, 7x2 filter wheel on my redcat 51

#

An issue I was observing with my 533 and filter wheel on the redcat was completely absent with the 571 and 7x2 afw.

#

Actually the 571 had an exceptionally flat field.

#

If there was some kind of problem with that filter wheel, I think it would carry over and manifest on other scopes and so far, the evidence does not support that as being the case.

frosty shard
#

When I sent those photos showing the reflection from my bad adapter, I noticed the tip of the baffle tube seemed more reflective than the rest

#

See what I mean?

frosty shard
#

Perhaps flocking that would help, though it is a tricky position

harsh matrix
#

Thats what made me flock it

#

I saw the same thing

frosty shard
#

Oh you already caught that nvm

harsh matrix
frosty shard
#

Anyway I'm flying to DFW so I will be disappearing

harsh matrix
#

Welcome

#

Anyway, it looks more reflective because the baffle tube can catch stray light from around the secondary mirror no problem

#

It gets illuminated by light bypassing the secondary mirror and that's what I believe is creating my problem.

#

If the 533 can image within the perimeter of that illuminated ring, I think you can get around the problem.

#

The 571 simply cant be spared.

tall summit
#

There is a know issue with the primary mirror tube baffle, when its not extended enough

harsh matrix
#

It came with one.

#

Before that was ever discovered.

#

The total length of the baffle tube is 200 mm.

#

That issue came about because the baffle tubes that were too short were 150 mm.

tall summit
harsh matrix
#

All RC6's have a baffle tube that is too short

#

Even to this day

#

I didnt know it was too short on my carbonstar until I already had the 8

#

Thats when I measured both of them and found the 8's to be beyond what was recommended in that infamous video and found the RC6's to be only 150 mm.

#

It got even more exaggerated when using a 0.67x reducer on that scope but that specific reducer created an anomaly that never calibrated out at 55 mm of back focus.

#

Strangely enough if you extended the back focus by another 20 mm, the circle vanished and flats worked again.

#

But that i found all of that out with a 533

#

The 571 revealed way too many issues

tall summit
#

@harsh matrix I actually went through a lot of back and forth with HighpointScientific with samples and everything, first thinking that maybe my specimen was an old stock or something. They still didnt admit to it, but kinda went all out

#

check this email:

harsh matrix
#

I told them the baffle tube was an inadequate length and they showed me a bunch of screenshots about how "it doesn't matter" but in all fairness, this was in response to the ring of illumination that reducer was producing.

tall summit
#

@harsh matrix

harsh matrix
#

Tbh this looks the exact same it always has. For the 533 that is.

#

Adding the filter wheel and OAG made no difference in the flats which tells me that the filter wheel and filters are not producing the artifact I see on the redcat, and that other issue woth the RC seems to be related to the larger sensor of the 571.

#

What a pain AwkwardSmile

harsh matrix
#

Must be a blank slate copy and paste response they prepared because of the making of that video.

#

The last 3 paragraphs were directed at you only though

#

That stuff was not included in the one they sent me

#

Thats where it diverges

tall summit
#

looks like they did the work on that one

harsh matrix
#

Also same goes for when they said the length is adequate for the native focal length.

#

Well they did but I think they didn't at the same time.

#

I dont think they accounted for just how reflective the interior of the baffle tubes is.

#

This was just, ridiculous.

#

They look like theyre a part of the secondary mirror

#

Thats a good chunk of why flat panel flats dont work with this scope

tall summit
#

why did you decide flocking vs some super black matte paint?

harsh matrix
#

And another reason why ive done sky flats since I got the scope.

#

Only problem was, my sky flats started giving me worse results than the flat panel flats

#

I had no clue why that was and still dont really.

harsh matrix
#

It would do a much better job up close near the camera but not that far from the camera.

#

It would definitely help but not to the same degree as flocking.

#

Also its a royal pain to stick a paint brush in the long tube

#

Getting an even coat of paint would have been a headache.

tall summit
#

@harsh matrix I get this flair on some stars, what does it look like to you?

harsh matrix

Sort of looks like a heat plume to me.

tall summit

Like a bubble of hot air is trapped right in top of the primary mirror.

I see the same sort of thing sometimes.

#

Oh great the green filter still has a hotspot.

stiff mason
harsh matrix
#

this is an ongoing issue with just the red and green filter in my 1.25" EFW

#

I have antlia lrgb-v pro filters in both filter wheels, and only the red and green ones in the 1.25" filter wheel have any issues

#

I think they have a defect

tall summit
#

Does the issue follow?

harsh matrix

it will remain roughly where it is

#

here, look at what i just sent Antlia, this is my control set of flats

taken with my redcat 51 and my 2" set of the filter series im having problems with

I'd have to retake calc 2 there which is a pretty much guaranteed F again with how awful the profs are.

harsh matrix
#

I just dont go back.

#

State law and school policy put me in this corner, not my own choices.

#

I failed because my allergies are god tier awful there, and my roommate left me severely sleep deprived.

#

I had the constant possibility of sleep paralysis looming over my head every day too.

#

Most of which was being driven by undiagnosed and untreated anxiety. But in general, the school forces you to live on campus for your first year so I did, and I got a very noisy roommate.

#

Quite literally the worst possible combination of things to have happen all at the same time.

#

I worked 10 to 12 hours a day on my school work and worked on it 7 days a week. I never took breaks, and I hard burned out by finals week.

#

Nothing I did worked, no amount of my studying yielded results, all because my brain was completely fried.

#

if it was truly as simple as I didn't feel like doing the work, I would have admitted that long ago, but I gave it my all and still came up short.

@frosty shard we are going to print various lengths of baffle tube extensions to eradicate any and all potential for stray light to get into the baffle tubes

I don't have access to my RC now but I can try to get measurements and see if there's a discrepancy

Because my secondary mirror assembly does not look like yours

the collimation screws are spaced much closer together and way closer to the center screw

im trying to make it to where you cant see into the baffle tube at all

high aspen

#

The weird thing is that the RC does have a choke point

#

Or mine does

#

I dunno if its the same for all but mine has a choke point that goes down to 48 mm at the primary mirror retaining ring.

#

Technically the baffle tube aperture does not need to be as large as it is which means it is realistic to cut it down further.

@frosty shard you ever looked down the inside of your RC and been able to see directly around the secondary mirror shroud from the perspective of the camera?

and not necessarily that light can bypass the secondary and become visible on the inside of the baffle tubes thonk

@frosty shard I guess there is an upper limit to how long and restrictive the baffle tube can be. AwkwardSmile

#

This is the laws of physics

#

These stars look like they have extreme spherical aberration and you cant focus them hardly at all.

#

It's actually pretty freaky

#

It looks like Hubble with its jacked up mirror

I was wondering why i god double spikes

due to thermal conditions

#

The whole OTA rotated

#

I might have an idea to why it rotated. I think the tube rings don't have a wide enough base and the flex slightly on the dovetail

#

Good lord my rc setup gives me so much trouble

#

Might go back to redcat

#

Can’t guide for crap

#

@harsh matrix I still have trouble knowing how do I balance my setup with a harmonic? I find it genuinely hard

vapid patio
#

Didn’t you say it shows as backlash if you are unbalanced and run the phd2 thing

harsh matrix
#

or acts like it

#

but you arent going to get close to balanced

#

all you can really do is shove the RC as far up the saddle as it will go without being unsafe

vapid patio
#

And not gonna lie my focuser is on its last life

#

It’s not even ment to be a astrophotography focuser

#

What’s the one you bought a while back

#

I belive focus and just overall stability of my imaging train could be the cause for my bad guiding tbh

harsh matrix
# vapid patio What’s the one you bought a while back
harsh matrix
#

@frosty shard remember the super scuffed light frame?

#

well the flats calibrated it perfectly

#

so the problem is the baffling

#

but how tf do i fix the baffling without effectively reducing the size of the primary mirror

#

cause that's what happened

#

the dark ring is way too thin

#

meaning that's just about how much of the primary was used

vapid patio
#

Is your stock baffle to short? Or is it clipping?

#

I’m curious

harsh matrix
#

or short

#

or both

#

the custom one is clipping

#

@frosty shard HA

#

I CAUGHT IT

#

The problem IS because of that tiny sliver where light can slip straight past the baffling and to the camera

#

What im talking about btw is the Crescent shaped beam on the light stopper I have in there

#

I cant tell if its making it down to the camera

#

The unfortunate thing is that if I have to make the stopper any smaller, I will end up cutting out a part of the primary mirror again

#

If i make it wider, it gives this thing every chance to make it to the camera

#

I cant see it when I put my eye where the camera would be

#

I cant see around the secondary mirror at all with the camera where it should be.

@harsh matrix When you say slide it up as much as possible without being unsafe should it always touch both clamps? Can it do fine on one?

i like to keep at least half of the rear clamp on the dovetail

And as for my eaf and filter wheel it doesn’t matter what position it’s in?

harsh matrix
#

you can do whatever you want with them

vapid patio
vapid patio
harsh matrix
#

the degree to which the movement of one axis affects the other depends on how close to the celestial pole you are

#

so calibrating at your target can help specifically at that declination but because of the degree to which that axial movement is bound to the other axis, you will be unable to accurately guide in any other point of the sky

#

calibrating at the meridian solves the axial movement issue at any other point in the sky, but can result in worse performance in cases where the scope is not well balanced if i had to guess

#

also it isnt necessarily guiding at the meridian

#

it's guiding at the celestial equator

#

that's where the movement of the RA and the dec are not bound to one another

vapid patio
#

Wow man thanks for the explanation

#

So it’s the equator that is best

#

Let’s say I’m going m51 and I move to guide at the celestial equator. Calibrate there then go back. I should get great results?

vapid patio
#

Because I had my telescope pull a 180 from m51 to stright behind and I thought that made no sense

vapid patio
# harsh matrix yes

Also as far as how much weight it needs, how can I tell if it needs to be slid down the counterweight shaft or up it pretty much acts the same either way

You can only know if you do some math

and has your imaging quality, tracking, auto focus results. has any of those improved?

how so for guiding? because I think that the flex,wobble, and slowly unfocusing is a contributor to my meh guiding

harsh matrix
#

@frosty shard I just went to a star, ready to collimate my RC, did repeated checks for both on axis and off axis astigmatism, and on axis coma, and nothing is weird.

#

It looks perfect.

#

It shouldn't be collimated anymore

#

Not even close.

#

Ive taken both mirror cells out repeatedly

#

The stars really dont look all that impressive but it's correct by all accounts.

#

I think the majority of what I see is tilt atp

#

I dont really care to take care of it atm since it looks incredibly minor
