Problems over problems

Today, I wanted to take photos. Took flats and flat darks and then went back outside when it was dark.

First, I had problems again with aligning my mount. Took me several attempts - I'm not sure if it's the GPS unit or something else.

When I had it finally aligned, I took a test shot of Altair and got this:












I thought that this was because I didn't collimate my scope correctly. So, I corrected it to get it to this:

But when I then checked closer, it was mis-aligned again. I asked at one of the forums and the answer was that this is most likely due to "some kind of lens flare". I wonder if it is the focal reducer. Will test this tomorrow.

... and now I have to collimate my scope again :-(
