I just got my HyperStar, ASIAir Pro and the ASI294 MC Pro and tried it out last night.
Focusing was no problem with a mask. Preview was a snap, just pick the object and the and the number of seconds for the shot. Live stacking was something of a problem though as you again pick the time in seconds for the shot, but no where I can find is there a place to select HOW MANY SHOTS you wish to take. The only options I see there are basically UNLIMITED or 10 minutes, 20 minutes and on up. Not much good if you wish to take15 shots at 4 seconds. Taking the unlimited is the only option that might work as you can just watch the number of shots pile up and when you have reached your number press the shoot button again and it stops.
The manual shows this, but doesn't mention the number of shots:
Live stacking is the automated onscreen stacking of multiple images in realtime ‒ this can be a great feature to show faint objects to friends and family or at a star party .
• Step 1: Switch the app to Preview mode, select the target you want to shoot on the mount control panel, GoTo to the target, and shoot a short test image to adjust image composition.
• Step 2: Switch the app to Live Stacking mode, Choosing Light frames select the exposure length by pressing the time entry , choosing a time from the roller and pressing OK.
The only place that mentions the number of shots is the Autorun area.
So, what am I doing wrong or missing?
