So I've finally gotten a chance to use my new ASI2600MC Pro cooled camera on my refractor a few weeks ago. Went after the Rosette Nebula and got almost 6 hours of imaging done over two nights. I could've done more, but on the final night, the nebula was dipping behind my neighbors roof so I gave up.
The image below is 69x300second exposures stacked using an L-eXtreme filter to only capture Hydrogen Alpha and Oxygen III. The imaging processing program I use allows me to split the RGB channels and recombine them using some math to create a false color Hydrogen, Oxygen, Oxygen image where those elements are assigned to specific RGB channels.
