Robin Yes, that feature alone is worth the price of the software! When setting up for the start of the capture, I turn the gain up to around 50%. That way, combined with the stretch, I can drop the exposure to much less than the the target (60s in this case). This allows minor positional adjustments...

One of the M31 frames loaded into SharpCap using the Test Camera 1 (Deep Sky). Display Histogram stretch applied to show object of interest, M31, at the centre. Without the stretch, the capture display looks like the image above.

Watch out for a blinking icon on the task bar which is a window asking for permission to proceed with the install. Still catches me out sometimes.

Robin Yes that is an in-progress capture of a single 60s frame - progress at botton right is 20/40. I can load up one of the frames later, stretch it and post back. It does clearly show M31 when stretched, that is how I ensure I am 'on target'. Mini histogram stretch is very useful. I can also post ...

Nice shape on the histogram and good figures for the min, max image statistics in FITS Liberator.

I think the front lawn needs a trim though

Very interesting Brian - a 7deg C drop.

A demonstration of what happens when 9am darks are applied to 9pm lights and vice versa would be very educational. An extreme test but should be a good demonstration about why to avoid temperature mismatches.

Bottom left button not mentioned in 2.09 doc. Have captured that for my notes.

Nice piece of work Brian and my compliments on the documentation.
