Easy deep-sky with ASI120MM despite a light-polluted suburban sky.
Perhaps the ASI174 should be more convenient for such an object.
Capture in 12-bit TIF with on-the-fly dark subtraction by Firecapture.
Deep sky stacker, then a bit of photoshop.
Little noise at borders that I forgot to crop (poor peripheral stacking due to variations in tracking from the EQ6 mount).
No flat, no dark, no offset, no autoguiding, no cooling, no... Easy indeed !
Clear skies,
Nicolas.
