Re: Auto exposure and Altair 290M

Robin, Put the 290M back in my dome last night. Downloaded the latest version of 3.2 Set auto exposure. It chose 13.1 sec which gave a reasonable histogram at about 10pm. Started a 12hr capture of .ser Re checked at 11pm. Histogram was low, exposure not changed from 13.1s Stopped sharpcap. Restarted...

Also, sometime after maki...

Re: Auto exposure and Altair 290M

Thanks Robin, that sounds good for All Sky use. Especially in day time or if the moon is up average exposure for the majority of the fov works best. Speed of change is less critical. Out of interest, how does it choose an exposure value, from the mid point of the histogram after any user limits are ...

Re: Auto exposure and Altair 290M

Update. I bought a ZWO 224mc

The auto exposure works well with this. Self adjusts between bright light and darkness.

Seems to be an issue with Altair cams as see another user of a gcam has the same problem.

Auto exposure and Altair 290M

Nothing in the manual about this. Tick the box but the histogram still shrivels away as light fades on my all sky dome.

What should it be doing / how is it activated and set up?

Thanks Rob

Re: qhy mini guidescope

Not had chance to test yet but picked up a cheap 16mm cs lens. FoV is much larger than 2deg but if Burly had success with a 12mm its worth a try. I also have a light nikon lens (330g) 70-200mm i can mount on the 290M with a TS filter box. After polar aligning i can easily remove as have fitted using...
