I am very tempted to off load the atik11000 to buy one of the zwo cameras you mentioned

Ah..this old chestnut.
Let's say you have a noiseless 95% QE camera ( I wish
)......then one might be tempted to say you could stack hundreds of 2 second exposures and expect to get a great result.
Sadly the physical reality is the photons are simply not raining down fast enough for that to work well with very dim objects/structures. Shot noise will dominate the image.
Guess I'll have to go back to my "old school" KAF16803 sensor... chilled to 65C below ambient... and calibrate out the noise...a good deal of which is from cosmic rays.
Anyway...the point is to explore what your gear can do and to have fun in the process
