Description

This is a re-touchup of my M20 data using StarTools 1.3. My original touch-up used Photoshop CS2, and is located here http://www.astrobin.com/109965/ (this link also has the link to the original TIFF which was produced by DSS and used as the basis for both version).

As mentioned in the other link, but repeated for easier reference: this is with an 8" Vixon VMC200L scope, 450D Astrodon modified DSLR (with cooler, hella hot here in summer), stock frame (no reducer or barlow). DSS report:

-> No Offset -> Dark: 10 frames (ISO : 400) exposure: 5 mn 0 s Method: Median Kappa-Sigma (Kappa = 2.00, Iterations = 5)-> Dark Flat: 20 frames (ISO : 400) exposure: 1/8 s Method:
