I am still struggling to get a half-decent pic and I am positive I am missing something very obvious due to inexperience.
I have:
Celestron NexStar 6SE
Wedge
Focal reducer f/6.3
Canon EOS 2000D
StellarMate
SkyAlign apparently doesn't support the wedge, so I used the "2 known starts" alignment.
The wedge is pointing towards North and set to 51 degrees as I am in London.
I pointed the scope to M 81, and it seems to be able to find it and track. When I take a pic with a 20-25 sec exposure I get this: Second-Ever.jpg
When increasing the exposure, e.g. 60 secs: First-Ever.jpg
