Yes, this scope/CCD combo is surprisingly sensitive - sometimes TOO sensitive, as the blooming on the bright stars is happening at times UNDER 2 minutes, and that is in H-a. The scope is an f/5 refractor with a 4" focuser, so it grabs as much light as you can throw at it - my downside is my step adapter to the camera - I still have to have the cone adapter made (done the drawings, keep forgetting to send them to my fabricator)
The 5 sub stack is a little cleaner, but not a lot.
