Tom,

THank you for your interest.

I have found this focuser
http://www.teleskop-service.de/Selbs...g.htm#TSOAZ2CN

But I am not sure it is really low profile... My Newtonian is a GSO
200/800
(http://www.teleskop-service.de/gssei...hau.htm#200800)

Cheers

Chris,

It depends on which variety of focuser you have on your
Newtonian. Some of them have an extension on the 2"
adapter. If you have one of these, it may be very difficult to
reach focus with. I found that the Vixen 2" adapter for their
refractor focusers worked on mine, allowing it to reach
focus (it takes up essentially no backfocus), and did thread
onto my focuser. Can't guarantee it will on yours, as I used
this on a 200/1000 (8" F/5) Newtonian. Short of that, the
only other option I would be aware of would be to replace
the current focuser with a low profile Crayford unit. I know
it would be somewhat costly, but the improvement in finding
focus might be worth it. You could always use an extension
tube to find focus visually. Both Feathertouch and Moonlight
Instruments make focusers that shoudl fit your scope. There
may be a lower cost alternative out there.

Thanks, Tom Davis

Hello,

I have a Canon Rebel (300D) on a 2" focuser (Newton 200/800 telescope).
The problem is that I cannot focus with the MPCC because the focuser hits
the tube. Is there a workaround?

Thank you

Chris
