A couple of definitions may help?

EP + webcam (sans lens) = EP Projection
EP + webcam + webcam lens = Afocal Projection

But why put the crappy webcam lens in the light path.

oy I'm confuzzled. I know I have to take the lens off the camera and screw in the adaptor. I know I can shove it in a barlow. I know I can screw in a filter but.....
Can I use any other eyepieces and if so how?
I know I'm being a pain.
Sorry.

The black bit in the middle screws to the eyepiece (the grey bit).  The camera with the adapter screwed in slots in the back.  This works well with an ep ~10mm LER

Hi all,
Please correct me if I am wrong, but what is missing to be said is that not every eyepiece comes with a thread on the top.  To set up the webcam as described you necessarily need an eyepiece with thread on the top so that you can screw it to the webcam tube (the one that normally slides into the focal tube or a Barlow lens).

I have just one 25mm ep threaded on the top with which I have tested the ep projection technique as described here, although I haven't found any advantage, either in focusing or image quality, on this approach relative to the use of a powermate x3 or x2, depending on the seeing conditions, as a focal extender.

Hi Fernando, the ep adapter shown above just clamps over any eyepiece, no thread required.

Hi Andy,
Thanks for replying.

Isn't the adapter (the black one) intended to go through the focus tube on the telescope when no ep is being used? If it is, it has a diameter smaller than the ep's diameter and then it wouldn't fit to be clamped on the ep's top, unless it was screwed to the eyepiece.  By the way this is the way I manage to do my testing with the ep and the webcam.

Maybe the black adapter iis not the same one that normally slides into the focus tube when you don't have any ep in the set up.  Is that right?

Hi Fernando,
One end of the black adaptor fits over your eyepiece and the toucam (with screw in adaptor) slides into the other end.
I hope this helps.

Well, it looks similar, but it only has clamping screws at one end...

I've never found that picture of the adaptor very good as it has the eyepiece attached and is low res.
I couldn't find another better one on the interweb so I've taken a pic of mine.
I hope this helps.

Please forgive me for asking this question AGAIN :-\ But I would like to ask for some advice for imaging Saturn, in colour, with the ToUcam.

I'll be using K3 for capture, my O-O SPX, with a x4 Image mate barlow with out my IR block. And I would be grateful if somebody could go through the camera control settings, for imaging Saturn :)
