my first post

Here's an image of M33 that I took under dark but not so transparent skies over several nights this fall. It was captured with a QSI WSG8 and an Astrodon LRGB filter set  including a 3 nm Ha filter through an FSQ 106EXIII. I'm new to Pixinsight and I must admit that I wasn't happy with my first attempt. So I used drizzle integration and deconvolution on my next attempt which enabled me to sharpen the image further but with only 14hrs worth of subs the dimmer regions of my image where pretty noisy. Pixinsight has several wonderful noise reducing processes but none of them can make up for a lack of signal. But I read a few posts by Vicent Peris and Rick S that described how to combine all my LRGB subs to create a super luminance master frame to boost the S.N.R. Well it worked! Here's where you can take a look with what I came up with:
