I have had a lot of luck with my plate solving in SGP with astrometry.net using both a 104 f/7 and a 130 f/7. I just switched to a wide field WO 73 f/5.9 (430mm focal length), and my plate solving now fails about 40% of the time. Sometimes in the same area of the sky where it just worked. I am wondering if anyone else has seen a correlation with shorter FO and plate solving problems.

Not at all, I use platesolve of astrometry.net with focal lengths ranging from 50mm to 2000mm. It is only a matter of parameters.

Make sure you download the proper index files to match/exceed your new wider FOV. Check out this link to the ansvr local Astrometry.net plate solver for Windows https://adgsoftware.com/ansvr/
