I recently purchased a Toucam 900nc and adapted an 8x50 finder scope I had left over from a GSO dob that I purchased. I removed the rear eyepiece and rear plate from the finder and located the focal point of the finder and placed the cam into the finder scope.
I am able to focus on objects in daylight with it.
Sat up till 1 am fiddling with the set up trying to get it to work then
last night I took everything out side and fired up PHD guiding, the software locks onto the scope control which I run from an ST4 adapter and a shoestring LPT adapter.
The camera is usb direct to Win xp and the software finds the camera no problems.
I have search extensively for answers to my problem but no luck so far.
When PHD guiding shows a rendition of the stars on the screen, i centered the finder on Jupiter and the 8x50 magnifies it and shows it as quite large and bright, PHD wont lock onto it for some reason.
Should I be locking it onto less brighter, smaller objects?
When I do get it to finally lock onto something it runs for about 5 min then the bottom settings line starts to flash on and off.
I haven't been able to find a definitive list of settings for the 900nc in PHD guiding do I use Iyuy or yuy2? 640 x 320 or 320 x240.
What camera settings should I use? auto, flicker free, black and white etc?
The screen on PHD is a grey colour and not black with the stars in relief is this correct?
