I'm rather a new person to SGP, but had very good luck with both of these plate solvers when using my SW100ED Pro (900mm), but I recently purchased an AT65EDQ (420mm) and tried it last night for the first time.
Sadly I couldn't get any solving to work with either of these and the new scope. I created a new equipment profile with the telescope set at 420mm.
My exposure times where definitely long enough and very similar to the SW100ED and Canon T5i @ ISO6400 for 20 or even 30 seconds.
I was looking at NGC 7686 and even tried a simpler one (which solved with the SW100ED) M31.
Any idea what I may be doing wrong that would cause this smaller scope to be unable to solve? Did I forget a setting somewhere?
