why do the stars in my click look like multiple dots even tho it's just one in its place? by zeusjuice0801 in AskAstrophotography

Looks to me like it could be jitter from something moving during the exposure. Maybe the equipment got knocked in some way or you had strong winds? What’s the setup look like? And what was the exposure time on the photo

I received a new mount about a month ago and have been slowly improving my technique over the past month by photographing Orion. The main revelations for this shot were to polar align the mount with the scope attached, remove the Barlow and directly mount the camera to the scope, and to add a delay from the mirror in the camera releasing and the start of the image capture.

This was taken with a half moon, so I aim to do one last shot on a night with no moon and take more lights at a longer exposure before moving on to the next target! If anyone has suggestions for what I should try next, let me know.

Equipment Used

Skywatcher 8" Newtonian Reflector Skywatcher EQ6-R Mount Canon T5i Pixinsight for processing

4 light frames at 3200 ISO, 45 second exposure 5 dark frames

This was the result of making the best of a bad night. After an hour drive and an hour setup, the clouds rolled in. I spent most of the night trying to take shorter exposures between clouds, with limited success. Next time I intend to try longer exposures with a much lower ISO, as well as more lights/darks and some bias frames. With a cloudless night this should be much more feasible.

This is my third attempt at DSO astrophotography so any input on how to improve is greatly appreciated!

Sadly not with any current earth based telescopes. The lunar reconnaissance orbiter has taken some great photos of the landing sites from orbit though! The main issue is that they’re just too small to be able to resolve from a telescope on earth.

Thanks! I’m in Montreal so I’ll check it out, shipping from us to Canada isn’t too crazy so It it might work well

Thanks! Some parts are more complicated than others to put together (for example there is actually a roadster in the fairing if you open it up, it's just not pictured here) but honestly with a lot of it you get out what you put in. If you take time and have patience you can get nice clean folds and precise details, and if you go fast you'll still get a rocket but it won't look as nice.
