I prefer DSLRs, but I'm going to play around a bit with a high sensitivity monochrome camera anyways for some planetary work, and maybe some galaxy imaging at long f/l. My question then is, how does basic imaging with a monochrome camera work? I figure that you can either take a single frame. Or a luminance, plus R,G,B frames. But with RGB, do you then still have a net black and white image? Or does assigning each color to a channel net you a color image in the end? I know it's all in the processing... -------------------- Martin William Optics 66SD Orion 100ED Orion 120-ST EQ PST-Ha Celestron CGE 1100 Canon Rebel XSI with Astronomik filters DSI-IIC Homemade spectroscope in progress...

You get black and white images in RGB which you assign to a channel in Photoshop or other software. -------------------- Dwight SBIG ST2000xm TEC 140 APO #74 Meade LX200 14 OTA Orion 12.5 DOB Celestron C8+ Celestron 102AZ Losmandy G11 Gemini Argo Navis Canon 350D self mod Hyperstar ST-4 Guider STV Guider Post Extras:       Pages: 1 Previous   Index   Next   Threaded   Extra information 8 registered and 3 anonymous users are browsing this forum.
