I've tried several fits images that plate solve easily with PlateSolver3. I want to use ASTAP on Voyager because of problems I'm having with PlateSolver2 and PlateSolver3.
I tried using star databases D50 and D80, neither one gives me a solution. I enter auto in the Stack Alignment tab FOV.
When I hit Solve current image I see it tries various FOVs starting with 9.5 and working its way through 0.4 before ending with 'No solution found!'
Any ideas?
I read some more posts related to this issue, and realized I was using a file with minimum information in the FITS headers. I tried another file with the relevant information in the FITS header and the astrometric solver worked just fine. I assume when I use ASTAP in Voyager to do real time plate solving ASTAP will perform just fine as long as I have the relevant information in the FITS header.
Any reasonable image will solve. Ting all FOV (10 down to 0.35 degrees) is one step. The other is the search range which you could set at 180 degrees. So that will be then a fully blind solve attempt. Then it should solve any reasonable good image within minutes.
Voyager will send the telescope posiion and FOV via the commandline. If these value are correct specified (via focal length, pixel size ...) a solution will be found in seconds.
