Hi there, I've recently jumped fully into the DSO side of astrophotography and have been having trouble with stars that aren't quite round. My last two imaging sessions have produced stars seemingly pointing in different directions across the field of the image. After the first image we collimated the scope and the problem has continued but we think our collimation may still be off.
I use a SkyWatcher 130PDS with a Canon 6D Mark II and the Baader MPCC Coma Corrector. The problem persists regardless of whether or not the coma corrector is in the imaging train. It also persisted regardless of the exposure time. I have uploaded processed images which show the problem, but if unprocessed files would be more helpful I can upload them also. The processed images have been cropped slightly.
If anyone has suggestions as to what the problem could be I'd really appreciate it.
Hi all i am wondering if there is someone or a few people that can help me with choosing the right and my first telescope any help would be great full thank you.
i intend to use it to look at deep sky objects like nebulas other solar systems if thats even possible and anything else out side of our solar system,
i also wish to view objects, planets and moons in our solar system,
i do wish to do some astrophotography in the future so if i can get a telescope that is brilliant at viewing and for photography that would be awesome
i have a budget of around £1500
the telescopes i have been looking at are these but i am so unsure i need some help with choosing the right one for me, if there is a cheaper option i am all down for that then i can buy some accessories to go with it,
thank you for taking your time to help me out
