Has anyone tried using eyepiece projection with a webcam??
I've been frustrated with small jupiter images and until I get a bigger scope I need to try everything possible (a 2x barlow is all I've tried so far). I've been mucking about with a 20mm lens and think I can successfully mate the Pixel Plus. Unfortunately cloudy skies haven't given me a chance to try this yet - Anyone tried this yet?? Dave Grennan, I'm sure you would have some advice.

All I could recommend to you John from what little experience I have done, is perhaps find a method of 'fixing' your webcam to the eyepece you want to use. Perhaps with tape? Then, using the programmes 'window' on your pc or laptop, manually focus as best you can and start taking an avi that way (then do your Registax or ImagePlus etc.).
Of course, start with the 20 to 25mm eyepiece first, then work your way up. Don't go straight for the 6mm - you'll be very disappointed, especially with the shallow elevation of Jupiter at present!

John,
In my inital setting up of a webcam I found it useful to pick a distant object during the day to check the focus and setup. It is alot easier when you can see everything and the target is stationary. You can also get a feel for the typical distances involved by just holding the webcam close to the eyepiece till you get an image on the screen.
Hope this is of some help.

The clouds cleared last night so I had a bash at this. Unfortunately there was virtually a gale force wind also, and the scope was getting buffeted all over the place.
Things did look promising, I was able to focus a half decent image of Jupiter using a 9mm lens. I didn't bother taking any AVIs due to the wind. Size of the planet has definitely substantially increased over prime focus with barlow so hopefully I will get more detail the next clear calm night.
