    Default webcam IR



    Hello, I've been tinkering with a modified webcam for prime focus. I realize that I can only expect so much. My main question is do I have to remove the IR filter if I'm to expect good planetary images, or no. And if anyone can suggest a entry level camera for when I decide to move up. I have seen the Astromania CGCMOS and Orion Starshoot which I believe are basically the same camera. And any advice on using a reducer. My main scope is an Orion Astroview 120st 120\600 f5

    I'm not an expert, but as you're using a refractor I think you should retain the IR filter in place, otherwise you would get loss of definition due to the aberration in the IR waveband.

    If you are buying a 1.25" nosepiece to put on your modded webcam, you can get those with an IR filter in place.

    SharpCap doesn't require a lot of fiddling around. Best to start with the default settings for a while and adjust things as you gain familiarity. Concentrate mainly on exposure length and gain for the time being.

    You should be able to pull in some nice video of the Moon. AVI or (if your cam supports it) SER video formats. Colorspace (in SharpCap) use RAW8 or RAW16 if your am will support either.

    I find that Autostakkert! is a much easier problem to use for stacking video frames vice Registax. Registax is great for its wavelet sharpening on the resulting stacked image.
