Can we get an astrophotography thread going?

If bad frames due to shaky $40 tripod count then here are some of my recents.
1. Comet Catalina, the tails are disappearing into the noise. Squigglies are visible on the stars due to vibrations from the plastic head on the tripod.

2. Pleiades, some nebulosity visible over the noise, again squigglies. Used the bottom tier kit 50-200 telezoom.
For the comet I used a 400mm Sigma lens.

2. Great Nebula in Orion. Again trailing and squigglies. I tokk many frames to process in DSS with all these. DSS refused to register the trailed stars and I facepalmed hard.
It is possible to do astro and have decent results with cheap lenses but you should definitely not cheap out on the tripod and head. Get the most beefy and stable ones, plain 3 way or geared head if possible. Avoid ball head for astro work.

Same tree, different night. Uploaded this in the last astro thread but I only recently figured out how to do comet style Startrails so this is a re-edit.
Would love to get into deep space astrophotography but I'm too much of a poorfag at the moment.

O-GPS1 and a Tair 300mm or a DA 55-300 would be a good start. Like I said above, don't cheap out on the tripod, microvibrations fuck shit up real bad.
If you are into DIY you can make a barndoor tracker with an arduino set containing the stepper motor, motor drive and LCD panel. You can do a lot with minimal money, but the sturdy tripod is a must.
>>2753564
>It is possible to do astro and have decent results
So with that setup could I get results as clear and detailed such as the OP image?
>Don't cheap out on the tripod
A good tripod is the one thing I do actually have, it has a ballhead but I can just remove that and mount directly to the tripod.
>>2753584
For such clear images you need a newtonian on a tracking EQ mount and do a composite image from several filtered ones. But you can still do decent images, and by decent I mean better ones than those I posted above. Actually a newtonian scope is not expensive, the tracking mount is the expensive one.

Alright cheers anon, I'll check those links out soon.
I just remembered, my dad has a telescope that he hasn't used in years, not sure if it's broken or if it can even mount a camera. I'm pretty sure it's just a cheap one, I'll come back with the brand/model later on.
>>2753711
All of your photos are lovely I am going to use one as my phone background ok
What's a good cheap digital camera I could use to get some shots of the moon or just the night sky in general?
>>2754618
Anything with bulb mode and at least with a one inch or m43 sensor, but APS-C is more preferable.
Get a Sony NEX 5n, Nikon D3300 or Pentax K-50, maybe a Canon 700D or 760D and a tripod. Tripod is a must.
Astrophotography is definitely not cheap.
>>2754618
the moon, deep-sky astro, and "landscape" astro all need different things. None of them are particularly cheap.
>the moon, and nothing else
Lots of focal length, doesn't need to be fast. Good-quality refracting telescope (note that anything you can buy in a department store for a few hundred bucks is junk, you're looking at more money than that)
>starry landscapes
Low-noise camera, capable of doing at least 3200, preferably 6400+, with acceptable noise. And a fast wide-angle lens. Samyang makes some good ones, though they're all-manual. f/2.8 minimum, f/2.0 or 1.4 is better. This is also what you want if you want to put the moon in the background of a landscape picture. The moon is so bright that you'll need to do some HDR stuff, or just shoot the moon separately and shoop it in.
>deep-sky
Star-tracking. Pentax can do this with their little GPS gizmo. It does work, and it's the cheapest way to do deep-sky, but it is not magic and is not nearly as good as a proper mount. Ideally you want a proper German equatorial mount. You then need optics. Ideally you'd want a fast reflecting telescope, but you can make do with something like a 200/4 or 300/4 for things that are both large and fairly bright (Andromeda, the Orion nebula, the Pleiades..) You also need to be willing to shoot dozens of exposures of the same thing and then process them together later.
>all of the above
a big, heavy, rock-stable tripod. Small, lightweight stuff need not apply.
some solar eclipse stuff.
I bought some Baader solar film and made a cardboard thing to put it on my 1500mm scope

>>2759147
I will one day senpai :(
>>2759147
Is it possible for me to buy just the mount, and put my camera and an ordinary photographic lens on it, and then later on buy a telescope?
cause I have a 300/4 that should be at least serviceable and it'd really help if I could buy stuff piecemeal instead of in one big $1k+ lump sum
>>2759214
yep you can, you will just need one of these (not sure how they're called in english - dovetails?) to put your camera directly on the mount.
and your 300/4 is perfectly fine for a lot of deep sky objects, like >>2753724 or other big nebulae!
>>2759217
So what kind of exposure times can that EQ5 give you?
I'm planning on going out in another week or so when there's a new moon. I have that little Pentax GPS gizmo. Which does work, but ain't magic. I can only really go to about 60s at 200mm and 30s at 300mm.
>>2759278
30s is plenty exposure for a 50-100-200 frame stacking
>>2759278
You can expose between 3 and 5 minutes at 400mm, it really depends of the accuracy of your polar alignment. Probably longer if you are careful about it. And it also depends where in the sky you are pointing at. (it moves way faster near the celestial equator)
>>2753558
does anyone have a tutorial on how to achieve this?
i remember taking multiple images, and stacking them
>>2760314

Whats a good Camera for Astrophotography?
Im looking at D810 A.
>>2763048
If you have to ask that then it is best not to choose the D810 A or the 6Da.
Get a regular everyday DSLR, a sturdy tripod, an astrotrek mount and a small refractor telescope.
I just did this.
>>2763346
This is fucking cool. Got anymore?
>>2763348
I do, but i'm just a beginner and i guess every previous timelapse i did is worse than this one i just posted.
Anyway, there is one more. Shame i haven't cared enough to un-tilt it, clouds are looking great there.
>>2763349
And one more.
>>2763349
What are you shooting with?
>>2763349
Oh, mistake. That's actually completely broken one, i had some stupid color shifts, probably from sensor temperature. That's "tilted" one, one i wanted to post.
>>2763352
Some of them were shoot with 350d, some (newer ones) with 50d. Kit lens, this plastic 18-55 II - i know it's shit, but i'm afraid of spending money because i feel more pressure to produce good-looking things with every dollar i spend on this hobby.
Alright, that's the last one. Not much of a night sky (full moon always makes stars barely visible), but i really like the moment when clouds are starting to make everything dark and dramatic, like some kind of apocalypse.
>>2763368
Something around one minute between the shots, ~18-20fps framerate.
I took this long ago. I want to get a better camera and lens :(

Do an experiment, leave the lens cap on, set high ISO and low shutter speed and make a shot with the viewfinder open. Now with the same settings do another one, this time with the viewfinder covered. Compare the two shots, and see how the light leak pattern is present in the shot.
DSLR tracking mounts question.
So there is that Pentax GPS thing that works if I have a Pentax DSLR. There are the Vixen Polarie, the iOptron Startracker and the Astrotrac tracker that can be upgraded for a scope.
What other options are there with reasonable accuracy? I'm not that big on DIY for a barndoor tracker mechanism and the ones I saw don't seem very accurate, also their setup and alignment seems very finicky and overly complicated.
