I'm using AIJ V5.2.0.09 and have a question about plate solving. I'm currently plate solving from AIJ using Ansvr on another PC on my local network, and that has been working well in the past. I now have a set of challenging images that won't solve with Ansvr, so I tried sending them to astrometry.net through AIJ, and those solves failed as well. I then tried solving the same images manually through nova.astrometry.net. and they solved successfully.
The difference is that it seems as if AIJ pre-selects the stars that are sent to Ansvr or astrometry.net for solving, and in this case only 6 or 7 stars are found on each image. However, when the images are uploaded to astrometry.net, and astrometry.net selects the stars, it finds a lot more, and can plate solve the images.
If I'm correct in my assumptions, is it possible to control the star selection parameters in AIJ so that more stars are found before sending the list of stars to the plate solving program? I've tried playing settings on the DP Astrometry Settings dialog in AIJ, but they don't seem to help in this case.
