Low Profile Focuser

I recently purchased a Celestron C8N-GT, and am looking to upgrade the focuser for a more photography friendly focuser. I would be interested in hearing anybody's experiences on any suitable low profile focusers. At the moment I am removing the 1.25" adapter and attaching the Camera (350D) directly to the existing focuser using the T-Ring, however this precludes me from using any UHC or LPR filters. Be good to hear of others experiences.

Dunno if its what you're looking for but the Finger Lakes PDF is top drawer:

Its pricey but I have one and I can't praise it enough. Totally automated (with FocusMax - free software) and talk about fine focusing - 1.25 micron per step and there's 7000 of them. And it'll carry a huge weight - I can;t remeber what the spec is but I have about 4kg hanging off mine...

Thanks Dave but its well over my budget.

John,
Just to confirm, are you physically attaching the EOS T-ring to the focuser, or, are you simply inserting the T-Adapter into the focuser?
I have an EOS T-ring and a 2" T-adapter. This allows me to insert the 2" T-adapter into the focuser. The 2" adapter can then take screw-on filters. The only thing "sticking out" beyond the focuser is the EOS T-ring and the camera.
Is this of any use to you?

Thanks Michael (I'm attaching the T-ring to the focuser) - but what I'm really looking for is a review of a low profile focuser like a KineOptics (helical crayford) or a JMI, or a GSO 10:1 low profile (currently available on ebay for just $134) sse the link : cgi.ebay.ie/GSO-10-1-Crayford-Focuser-fo...122#ebayphotohosting . What I was really wondering is if anybody on the boards might have had any experience with any of the above and the Celestron C8N-GT. Looks like I'll have to blaze my own trail. What I'm wondering is if I'll need an extension tube to revert to visual use - that'd be a pain.

Have you consodered raising the primary mirror? This would give alot more focus range and may give more options in the selection of a focuser.
Unfortunately, I don't have any experience with a low profile focuser so can't help you with that one.
