I'm considering replacing the eyepiece in a 6-inch newtonian reflector with an image sensor of some flavour... I've hacked up a web cam but the sensor at 1/4" is too small; the effective field of view is something under half a degree so I can't, for example, fit a whole moon in.
An adaptor for my DSLR won't allow close enough focus as the sensor is too far back in the camera body.
Anyone hacked a camera with a half-inch or larger sensor for this purpose? I need to be able to do long exposures (aka 'bulb mode') for deep space objects but also streamed images out to be able to stack them for noise reduction.
Or can recommend a hobby price (i.e. not a thousand quid!) sensor or camera unit? Or point me at data for the occasional sensors that pop up on the bay?
My google-fu is not strong on this.
