No worries, thanks anyway.
I just thought a comparison between say 1 hr of exposure time compared to 10 hrs with the same data, processed the same way, would be very interesting.

Here's an example. NGC7497 imaged with Tak FSQ-106ED and QSI-683 camera (small crop from centre of field containing NGC7497 and some dark dust.). Subs were 15 mins each. The attached images are a simple integration and stretch of 5, 10, 20 and 40 subs = 75 mins, 150 mins, 300 mins and 600 mins.
According to PI's SubframeSelector script the noise measurements are: 3798, 3348, 2756 and 1912.
This is a fairly challenging target...
Cheers,
Rick.
