Has anyone ever visually tried a filter wheel with a newtonian/dobsonian....successfully that is... ;)
My thinking is using this instead of buying 2" filters and a filter slide...

The main problem is that some filter wheels when installed may be too tall to allow eyepieces to come to focus in some Newtonians that have low-profile focusers with limited travel. Some require that the primary mirror be moved up in the scope a bit (or in my case, the trusses be shortened). Clear skies to you.

I haven't tried it, but where would you mount it? On the outside of the UTA? In order to be inside, you would need a flat side on the UTA. I suppose a square or "D" shaped UTA would allow that.

I think I can easily work around any focus issues.
It would mount between the focuser and eyepiece.
I'm thinking that this would be no different than using one of the Lumicon filter slides...as far as filter position relative to the eyepiece is concerned.

I've had a filter wheel on my 28 inch scope for about 8 years now and have found it to be the main reason I use my filters so much. I got mine from Aurora Precision http://www.aurorap.c...ilter-wheel.htm and covered both sides of the wheel with a thin sheet of ABS plastic to keep the filters clean and to prevent dew from forming. It’s worked great, and I particularly like the click stop feature so I know when the filter is centered.
