Hello,

I wanted to use ASTAP to find JWST and see it more in its orbit.
I took two images about 1hr apart at coordinates from JPL Horizon.
Trying to analyze the images with ASTAP I ran into following challenges:

  1. The images are from APS-C 26MP camera and pretty large (color 300MB / L 100MB)
  2. This makes blink very slow. Also it seems a lot of solve/computation is done again for each blinked image. Is is possible to cache?
  3. I could not find JWST in the huge frame, so I wanted to look at coordinates. But the slowness of the update made the UI almost impossible to use. I wanted to move the cursor around and see the coordinates until I am at the spot that the JPL ephemeris said. Also want to see the coordinate grid to help. Maybe mark a spot in one frame and see it in the other? I also wanted to zoom in on some area but hat was slow.
  4. I have the RA?DEC for beginning and end of the hr where I imaged. But I can only put one marker in the image at RA/DEC. How can I put multiple marker at RA/DEC?

I have the data uploaded if someone wants to experiment.

Exposure is ca 6:00 and 7:00 UT from ephemeris table.
