hi done a write up a while ago, this is a more in depth look at setting up a camera to pc for video capture and recording. camera... we will use an analogue cctv camera suitable for astronomy in this guide. this camera is the phil dyer camera. fitting the camera to the telescope. there are various adapters that can be used, c mount to 1.25 , c mount to t mount. this is the c mount to 1.25 and fit's in place of a lens. connectors there are few options for getting the av signal to your computer, bnc connector, this fit's on to the back of the camera and has a rca cable fitted to it. this is another option.. 75 ohm coaxial cable with bnc connection you will require a bnc male to rca male adapter for above cable. usb video grabber.. this changes the analogue video signal to a digital signal and capture software allows you to view/record and snapshot an image from your camera.

this is examples for video astronomy, there are many style's used in video capture, this tutorial is suited for more in depth video capture. capturing video images for example the moon, the moon rotate's around the earth on an axis, so we require a mount that will track the moon,what do we mean by this,,, the mount or tripod fitted with a scope when aligned will follow the movement of the moon allowing the camera to keep the moon in it's field of view. these are called alt/az mounts another option is an eq mount an eq mount,a simple tracking motor can be added to these mounts to give basic tracking. a simple r/a tracking motor. if you have a larger budget goto mounts are a great upgrade. these come with a handset and when calibrated you can pick an object in the night sky the telescope will slew to and track it for video capture. the above mounts also come in goto models, there are many manufacturers and design's of goto here are a few examples below. some tracking scopes can be upgraded via fitting a goto handset or by buying cables and linking to a pc with software that allows telescope control. eq goto mounts can also use a very good program called eqmod.
