Using a video camera for autoguiding

[blackbetty50]

I recently purchased an EQ5 mount for my GSO 8 inch reflector which had previously been mounted on a Dob base. Apart from intending to pull the mount down and re-grease it, I would like to use autoguiding software on it.
The mount came with both RA and Dec motors and i had read that it was possible to use guiding software to turn the scope into something other than a push pull.
I have modified the motor controller with the ST4 upgrade and have ordered the cabling and parallel port guide (GPINT-PT) from Shoestring Astronomy.
I intend to use PHDguiding software on my laptop.
As yet I am still waiting for the port guide to arrive to test if my ST4 is working correctly.
I have a pretty limited budget (zilch lol) but have quite a few video cameras and was wanting information on perhaps using one for a guiding camera.
I don't want to use the vidcam for photography just guiding the scope.
One of the cameras I have is an old Panasonic NV-GS35, specs below:

Lens Part
Image Sensor Total: 1/6CCD (800k pixels, Total), Image Sensor - Moving Picture/Still Picture: Moving Pictures / Still ,Pictures-400k, Effective, F Value:F1.8 (Wide) /F3.9 (Tele), Optical Zoom: 30 x Variable Speed Zoom, Focal Length: 1.9 - 57mm, Filter Diameter: 30.5mm, 35mm Film: 35.7 - 1072mm, Lens Brand: Panasonic
Camera Part
Minimum Illumination: 2 Lux (Colour Night View), Focus: AF/Manual, White Balance: Auto/Indoor/Outdoor/Set, High Speed Shutter: Tape Mode 1/50 - 1/8000 sec. Card Mode 1/5 - 1/5000 sec. Iris: Auto/Manual Programme AE: Yes (Sports/ Portrait/ Low Light/ Spot Light/ Surf and Snow), Backlight Compensation: Yes, EVF: 0.33(113k pixels) Colour, Monitor: 2.5inch LCD(105k pixels), Microphone: Stereo Zoom Mic, Wind Noise Reduction, Date Recording: Auto Date (In Data Code), Fade in/out: Black or White, Rec. Review: Yes, Image Stabilizer: SIS, Digital Zoom: Yes (50x/1000x), LED Video Light: Yes, Quick Start: 1.7 sec.(approx.), WEB Camera Function: Yes (Motion JPEG 320 x 240 approx. 6fps)

Would this be suitable for the purpose?

If this is suitable I need some guidance on how to mount the camera and where about on the scope.
I had intended to use a quick release mount like the attached pics with a bit of modification but was wondering if there was something else available?

I suppose more importantly does PHDguiding have provision to use the video camera? Would I need to install ASCOM drivers?
:thanx:

Have decided to source a spc900nc and spotting scope, thanks

I'm a big fan of breaking from the norm and doing things a bit different, but I believe the camera will struggle to be sensitive enough given the 2lux min illumination. I have also experienced zoom lenses have optical artefacts even on expensive set ups and need to be stopped down a bit to reduce them.

The guide scope I currently use an old 80mm Achromatic f5 with a UV/IR fringe filter and DSI 2 pro behind it and most times I get a star bright enough to track on.

Good luck with your endeavours.

I agree, not sure if you 2lux will cut it.

But using video for autoguiding is certainly possible. I use a Watec WAT-902H2 video camera, connected to a Video2USB converted and Metaguide as the guiding software. All works nicely, at the moment I am trying to fine tune the guiding.

The Watec camera is connected to my finder scope (9x50) and picks up the brighter stars, the spc900nc would be good as well.

Thanks for the replies, I located a 900nc and have modified an 8x50 finder scope to take it. All I need now is some good weather with clear skies.
A bit like hens teeth at the moment here in Adelaide.
