can someone help me process this ive been trying but couldn't get the ring portion correctly

you want 20 ish

burnt latch
#

is that whats causing the problem?

#

what should the ap size be?

fading plume
#

quite likely

#

depends how large saturn is

#

you want 15-30 ish with minimal overlap

theres not much data here so you cant get cassini.

I just handheld my phone against my 8“ so it’s basically just one singular image

#

For imaging Jupiter or Saturn untracked with an 8“ dob, do I go for the highest magnification I can go and let it glide across the screen for like 8s or do I use less and then I can let it stay in for longer and later crop ?

More zoom is better for planets

thats just wrong

#

Jupiter actually does have an atmosphere, the biggest and thickest one in our solar system

#

huuuge atmosphere

#

The atmosphere of Jupiter is the largest planetary atmosphere in the Solar System. It is mostly made of molecular hydrogen and helium in roughly solar proportions; other chemical compounds are present only in small amounts and include methane, ammonia, hydrogen sulfide, and water. Although water is thought to reside deep in the atmosphere, its d...

Oh also, does field rotation affect the sharpness of planets? I’m on alt-az and I’m wondering if autstakkert somehow accounts for that or if an eq mount is that necessary

Saturn from last night

2500+ frames - 15% stacked

Orion XT8 and QHY 5L-II M

My barlow is ass and paired with iffy seeing im not getting the most out of these optics.

#

Also im still getting used to offset so the bright band on saturn was overexposed a bit

First light with CH4 filter

I need to try ch4 juppy some time

Saturn looks soo good in ch4

#

Maybe someone should try a ice giant with ch4

tight canyon
#

2nd time ever attempting imaging, and the first time I’ve ever seen a distinguished line between the rings of Saturn and the giant. It may not be much, but it was my ‘holy sh*t’ moment that will probably catapult me deep into AP. No tracking, just a DSLR T-ringed to a 2x Barlow on a 900/114 f/7.8 skywatcher reflector. Ngl I’m a little proud of myself

Yeah there’s way too little signal there

#

Could do it with a an eq mount that can keep the image steady at a high focal length for at least a second I guess

But yeah, good luck with that

because uranus and neptune is made almost etiraly made of methane

I used 50ms exposures for my CH4 Jupiter, and I have to use around 20ms exposures with around 600 gain for Neptune without CH4 filter

eternal solstice
#

ooooh

#

wow

livid sierra
#

And the CH4 filter is only a 20nm bandpass

#

The ZWO one that is, others are even tighter

It's probably possible, ice giants in CH4, just really hard I think

Pushing maximum gain and 100ms exposures at f/30. In live view it was an actual structure you could see. Effects of limb darkening were apparent with enough time and averaging em out

You might just be the first to get them all in CH4

If Tom gets Neptune with an SNR high enough to not be grainy around the edges, in CH4 I will venmo him $40 immediately lmao

#

You would be dealing with I discrete photons at that point, a night of great seeing or better is the only time to get it.

uncut glade
#

I mean, just getting over the QE losses at that band pass, physical distance, and current elevation would be insane, combined with the angular size? It would be near comparable difficulty to detecting volcanoes on IO.

#

I would be BEYOND ecstatic to be proven wrong, but it just seems like it would need at a minimum, hours of data in great conditions

Good morning. I got this image a couple nights ago. Clear but seeing was rated 2/5 and Saturn was at about 20 deg alt. I was using my ADC for the first time. Is this the best that can be expected given conditions?

tbf it's pretty good that you got cassini at all

# dark cargo Just looks like bad seeing. ADC can't fix that unfortunately. Does saturn actual...

I think it does come a bit higher, later on. I remember it didn't come up as high as Jupiter last year, but I think it did/does come up to 25-30 degrees, right now at insane hours. As in "I get up at 5:30 and don't want to wait to 2 to image and have to put stuff away and get an hr of sleep" insane. 🙂 I look forward to what I can do now that I've seen this preview though. The bands are showing up pretty well even in this.

That’s about the best I can get with 5 inches of aperture kekw

Aye some are pretty good. I reckon my limitation is mostly seeing cause I had better results with a slightly smaller scope during opposition

Try, the images need to be 7/10 minutes apart, you need to get around 1 and a half minute videos, stack them, process them, and then you can make it into a gif

dark cargo

You could do it pretty easily with pipp

green pebble

He can try it

tidal crow

Yea join then output as a video, you can do either lossless compression or lossy for less file size. If you want to reduce the file size further you could use handbrake to encode it better. But the gif is fine too.

#

Under output options:

#

sure you can reorder the images in the source files tab, i think theres options in another tab to do more complicated things, under animation options tab

#

nah looks fine I think, I think you could do a bit more sharpening?

#

I think astrosurface has some way to do batch processing, but I haven't used it

#

might be something on the website?

#

Ah just 250 stacked frames per image? That is really low then, no wonder.

#

untick the white/black point options in input options? If they are ticked? Pipp shoudn't change the brightness?

#

oh sorry i meant processing options

untick both, they change the histogram pretty sure

tidal crow
#

I think thats the primary monkaS

#

If i cant adjust the secondary

green pebble
#

Its not the primary, can you see the optical tube evenly

#

Also i forgot to tell you but when collimating point your scope to a light source (not the sun) it will be easier to collimate

tidal crow

It is kinda at a light source

#

The right upper screw is too stiff for me to rotate but the others arent stiff

tidal crow
#

Oh god i screwed up

#

Not centered

green pebble
#

Its okey

#

Listen

#

So unscrew the stiff one, and try screwing in the not stiff ones

#

But it looks like your secondary is very easy to collimate, and your primary is a tad bit out

#

Its just logic

tidal crow
#

Ig imma try

Just play with the screws until the optical tube is even on the sides

Hi planetary nerds, I'm doing a bit of work on Seeing and I have a few questions.
First, is there some kind of map, table or formula to have an estimate of the typical seeing value of different areas around the globe? Or at least a relation between temperature and humidity and the seeing?
Second, I guess the effects of seeing are similar to applying a gaussian blur with a radius of fwhm/(2sqrt(2*ln(2))) but I also know different wavelenghts gets affected differently. What is the relation between the wavelenght and the seeing amplitude, proportional to 1/lambda, or 1/lambda^2 (as in the refraction index formula)?
Thanks for your help ^^

Also, if you take let’s say 9 minute vids on Saturn (30k frames), would Saturn be blurred by its rotation?

Because I take 10k frames and my Saturn is super noisy

I could really use collimation and an adc 😭

#

My c8 is from 1975 and i dont believe it was every collimated, or at least collimated recently and when I unfocused a star I could see the secondary wasnt dead on but it wasnt bad. Also the red and blue fringing on edges may be a combination of no adc and CA from a cheap barlow im not sure.

Glad to help.

#

Collimation plays a role in fringing the better your collimation is the less fringe you will have an adc cuts out all fringe but having as best collimation you can manage should do most of the work

Yesterday my collimation was spot on, the seeing and transparency was awesome and i expect some good results

I need some help with some planetary imaging

#

I’m trying to get Saturn less noisy without being it too dim in the live feed while also having good frame rate

#

The lowest I can go is probably 300 gain and maybe 10-25 exposure ms

#

How do I make it have less gain while also having a bright Saturn in the live feed

#

Also FC is the capturing software

#

The best I can do

white prawn
#

I think that's a classic "either or" situation.

uncut glade
#

Absolutely insane lol

dark cargo

#

Probably the best you could do? saturn is quite a lot dimmer than the other big visible planets. I have to use a shutter speed of 1/60th for it compared to around 1/300th for jupiter

steep apex
#

@dark cargo Thank you!

livid sierra
#

@steep apex use the histogram to determine exposure and gain. 60-80% histogram. If you think Saturn is too dim in the liveview to see, use the screen adjustment feature to increase gamma/brightness. It only affects the preview, not the data recorded

#

I image Saturn with ~8ms exposures and around 500+ gain.

uncut glade
#

The histogram rule, is that for ease of processing or is it for like, actual SNR purposes I don’t know about? Because I’ve been imaging at about 30% histogram to punch through my seeing

remote star
#

by that I mean you can take a pretty dark video and then brighten it up

#

did that today and I found it helped a lot

random pecan
#

That’s awesome

steep apex
#

You guys think getting more frames (thinking 20k-30k) would pull out more bands and resolve Cassini more?

indigo oak
#

20-30k seems like more than enough. How’s your seeing?

steep apex
indigo oak
#

Saturns fairly difficult tbh, never rises high for me

uncut glade
#

To say you resolved something, would it technically be accurate to say that even if it was 1 pixel wide?

#

Like say, imaging features on ganymede that are 0.1" wide, and your pixel scale is 0.1", and the feature is apparent in that single pixel as a color or contrast variation, does that count as resolving them?

#

Or is that just a detection?

#

2x2 pixels counts obviously, but I'm just wondering because the definitions seems up in the air, no pun intended ;)

hasty hull
#

Wouldn’t say so in most cases

#

Like plenty of stars are under a tenth of an arcsecond across and many people’s pixel scales are even smaller than that

But you couldn’t have resolved the star even if your resolution is theoretically enough

uncut glade
#

Second, likely far dumber question, even with lucky or speckle imaging techniques thats not possible? I don't see how we can resolve detail finer than that on ganymede, like Tom's blue image from opposition, but we can't say we've resolved asteroids that size?

#

Thank you for the response btw

hasty hull
#

Which is why getting Ganymede/Io detail is much easier when they’re in transit across Jupiter

#

Because they essentially become a part of Jupiter’s disc then

uncut glade
#

Ohhhh

That makes sense, thanks!

Just as expected. But yeah the backfocus might be issue even if I use barlow. Hope it's clear night today so I can test.

would anyone be willing to process a stacked saturn of mine, i tend to over cook it?

tardy iris

If the quality graph looks like this, what percentage should i stack? (5k+ frames)

uncut glade
#

I generally do a stack at the point where the graph intersects the vertical 50% line, and then double that to test SNR vs detail

#

Horizontal****

#

So in this case, at like the 5% and 10 percent marks

safe compass

@dark cargo hope i'm not interrupting by pinging you, i don't know what time it is for you, but i'm looking at jupiter using my liveview and i cannot see any details other than it being a ''orange-ish'' glob

I might try using CC

nevermind, can't find a way to attach both

Just went out and tried my new setup, 8” dob, 585mc, ADC and televue 3x. I’ll share the stacked image and if you want you can process it as I’m not very good at registax 😂

If you are collimated and the scope had some time to cool down outside it could have been just terrible seeing. Also for that picture you posted below were you not using a barlow at all? At 600mm fl with big dlsr pixels the planet will be really small, actually at F4 its gonna be pretty hard to get the right barlow power.... Actually damn really hard as your pixel size if 5.7um, using the formula: 6 times 5.7 divided by 4 = You'd want an 8.55x barlow..... I think it's possible to get that by stacking barlow or something but it would be really cursed.

white prawn
#

Stacking 3 2x Barlows would get you close though if I'm doing my math right.

#

Woah that would be a little cursed.

is it normal for pipp to output a 136gb file after processing a 6000 frames video

Yes. If you didn’t crop anything or debayered the footage.
