i have a few cctv cameras including a sony 12v 1/2" chip one

has anyone used these and a usb 2 capture card/dongle via the composite output on the camera and what was the results like

This is basically what the mintron camera is, although the mintron allows you to stack frames 'on the fly' to obtain longer exposures (upto about 2.56 seconds). The results from using the mintron are quite pleasant, but without the longer exposure option, you will be restricted to brighter objects (like an unmodified webcam)

I have a CCTV image sensor set up ready to try on the scope. It's a 1/3" Sony SuperHAD with a claimed sensitivity of 0.001 lux in greyscale. I've tried it as a CCTV camera and it's certainly as sensitive as the human eye so better that the usual unmodified webcam. I also have a Philips Vesta webcam with a view to long exposure mod.

Good point, Gina, had not considered the better sensitivity of the chip.

At the end of the day, K, if you have the bits already, you have nothing to lose by giving it a go and seeing how it compares.

Have a look here:

Telescope Reviews: Viewing forum: Video and Electronically Assisted Astronomy

they seem to have there uses, cctv to capturedongle to screen or TV or to internet for 'live' viewing (Night Skies Network)

looks cheap and fun.
