I just found out I had a 25 mm in a odd's and sod's box so I managed to get the barlow and an eyepiece to focius so all I need now is to try and get the wecam to focus and the jobs a good one...Here 's hoping for the next clear night .

So just to re cap ..LPF for DSLR focus.. 50mm extension for the eye pieces to focus remove the 50mm and replace with a 25mm extension for eye piece and a barlow.. Now god only knows what I need for the webcam..

Cheers guys,

So I have a brand new LPF for DSLR focus, a 2 inch extension tube for visual and what would you say I need then another 2 inch for use of my barlow and Webcam.. OMG add my barlow and eye piece and I will need tp buy some step ladders also..LOL

I need advice please…Am I missing something or I have I got to buy another piece of kit to use this scope.

I have a f4.8 short tube Orion Optics Newtonian, I changed the focuser for a lower profile one so I could achieve focus using a DSLR.

I then found I could not achieve focus using my eyepieces so I purchased a 2 inch extension tube I can get focus now with my eyepieces , thing is I can’t use a barlow with any of my eyepieces or achieve focus using a webcam with or without the extension tube in place.

What else do I need or where did I go wrong, I spent one of the very few clear nights this week faffing about trying to focus the webcam on a bright star before attempting to capture Saturn.

Collimation was spot on, cooling down time was allowed, no dew issues and the seeing was as good as we have had for ages, my other scopes were operating fine during the same session so I don’t think it was down to any of the above factors.

Any thoughts or advice would be most welcome

Yes, use any capture software you have. It won't show the webcam as "connected" otherwise.

VM stands for Virtual Machine, google it, you may be able to download a trial version and do your doings and never use it again..You do need a copy (Legal) of XP OS to run on VMWare though. PM if you want more on VMWare.

I think the long exposure mod will sort out the sensitivity issues. Question!! would you need the IR/UV cut filter if you were only using this as a guide cam?

I had trouble after flashing mine in VMWare 6 running XP on a Vista laptop. After flashing it I closed VMWare and expected my original SPC900NC drivers to pick it up but it did not, all I had was "Unidentified HardWare" showing in "Device Manager" I even tried the original drivers disk that came with my SPC900NC..Vista failed to install any drivers until I had uninstalled the "Device" I then download and ran the driver that "Russ" linked to. Works fine now. Shows up as an SPC900NC in Vista. Don't know what I am going to do with 3 of them, I have a guide cam..lol
