Your settings look pretty much identical to mine, ( from memory- I will double check next time I fire her up)

However while I have no problem in setting exposure times- only tried 5 , 10, seconds and a sequence of 2 or 3 - using KStars/EKOS on a laptop- I can’t seem to set exposure time in the app- both in iOS and in Android.

Also while I get a message saying image saved to my device I can’t see it in gallery ( in the app)

I can see the images on a laptop.

Not sure why, I am going to email Jaseem right now asking for his advice

Will post pr ogress, either here or my original thread
