I am trying to write a python program that takes 10 pictures in a row and renames them as they are taken, but when I run the script, some of the pictures are missing. I end up getting Picture0, Picture1, Picture2, Picture4, Picture6, Picture7, Picture8, Picture9, or something of the like where a few numbers are skipped. I have successfully run the code once or twice where all the pictures came through, but most times, I end up with fewer pictures than I should. The python program calls the following script to take the pictures and runs 10 times:
It's better to use INDI Python client than to use scripts like these. At any rate, you should check the state of CCD_EXPOSURE, once it turns from BUSY to OK, then you can download the image. Never make any assumptions solely on timing.
