Last night I had a chance to go to a less light polluted sky and setup my telescope. I wanted to take some shots for the nebulas in Orion, however I wasn't able to get a proper polar alignment for the required long exposures...
I'm at a latitude of 21.45" North. I wear eyeglasses and I am not the best in spotting stars at sky, so I rely on binoculars to find and spot Polaris and point the tripod in its direction, I have a compass as well but I am starting to doubt its accuracy...
I also have the polar finder scope installed (and properly aligned) on the mount and a 8x50 finderscope. All of those I use to find and work on the alignment of the telescope, and with all of those except the polar finder scope I can see Polaris very easily. I am not sure whether the issue is because of the scale of the latitude is not accurate on the mount (so I end up much higher or lower than what I need) or because the magnification of the finder scope is weaker than the other optics I use to show the star, but no matter what I do I cannot see the star through that scope.
I would like to know which is not accurate of these: (or start getting things sorted out on what's the inaccurate part in this sequence)
- Is there any chance that the latitude scale is not accurate or too small (or tight) for it to be accurate and show my correct latitude point? (I know it is divided by 2 degrees, but I'm at 21.45, so I set this roughly a little bit before the 22" mark)
- Or is it about magnification power and my eyes are not helping?
I'm having some ideas on solving this problem, but those ideas involving a DIY polar alignment camera. I already have a mono QHY5LII camera I use it with a mini-guide scope. And I notice that this camera and the guide scope have a slim body and 1.25" diameter and the camera is sensitive as well. I also happen to have a 3d printer, and the polar finder scope front cap on the mount is round and is hollow, so I can make another role for the guide scope and camera and print a mount and slide it in the polar finder tube and use it as a way to find and align the mount to Polaris. I'm just not sure how that will end up or how effective it will be...
Anyone had any experience with such solutions? Or before, with such problems in seeing Polaris?
Really appreciate your feedback and help!
