Learning a lot from Robin, and SharpCap!

Hi Robin,
I started in astrophotography about 8 years ago with a CCD camera, pier and 10" RC scope. I really did not understand anything about a sub's length and how it affected the final image. But by my own logic I went for long exposures 10-20 min for RGB. Then I sold that system 3 years ago and got a travel system with CMOS camera. I carried forward that habit, and have been using 10 min subs. Wrong.
Then about a month ago I ran across your presentation on the topic of Deep Sky CMOS Imaging. Finally I began to understand what factors really affect the result. And how wrong I was! SharpCap gives the tools to determine the optimum exposure time, gain/offset for the imaging system, with the factors of equipment, skies brightness, etc. I am new to SharpCap, and am learning how to use it with my system.
So thanks for your contributions and hard work for better astrophotography!
