Re: Help with processing M33

Hi Arrowstar here's my processing of your new stack. As far as noise, and keeping in mind that I do not use a DSLR and am not familiar with their noise characteristics and such, I'm wondering if your calibration frames could be contributing to noise.

Re: Help with processing M33

Hi Arrowstar, I had a go at your data, what you have seems pretty good, you just,as you mentioned, need more of it. There is no substitute for photons ;) below is my result along with the log file.

Re: Still lost after 3 clicks

I cant help you with your camera settings or exposure times as I use a OSC ccd camera so am not familiar with your type of camera. I know I've read much discussion on ISO settings on other forums. Ecuadors comment " Frames that have trailed are thrown away, but you can certainly use frames with plan...
