opinions needed on subs

[raymo]

Being as I just can't get my head around the more involved image
processing, and when I do learn something I have trouble remembering
it for very long, I am limited to either a few longer subs or a lot of
shorter ones, and then DSS. I can't decide which. The 2 attached images are an example of my dilemma. The denser one was 2 subs, 20 and 25secs@6400. The less dense one was 40x 13secs @ 3200. One shows many more stars and denser colour, but the other shows more delicate detail. What go you think?

Anyone know why I have suddenly got 2 clipped corners on the less dense image?

Image scale suggests to me that the first pic was taken with the 8" newt and second the 80mm achro refractor. You're comparing apples to oranges here. You need to compare those exposures with only one scope.

Very true.
