What was it that impressed you with the LX200R mount?
Where in the image train was the FR located? I assume you are using a DSLR? The F6.3 SCT FR was never really designed for that size image circle so I guess you will not be happy with it. The Lumicon Giant Easy Guider however was and even though not talked of much these days, I recomend you consider it. Not sure of its performance with the new R series Meades though?

Mike,
I had the lumicon Giant easy guider on my C11...I felt it performed very well even though I only used it for the focal reducer not off axis guiding....at $400USD I was hopeing to get something more dedicated to my cause then off axis equipment....I have sent Lumicon a email but I think it will be more dedicated to the standard SCT.
The mount is Losmandy G11 and was guided with the Sbig ST-402XME through CCDSoft....corrections were prodominently less then .30 what ever that means and the sub exposure were 1.5 seconds with .5 second delay between corrections...what I liked about the guiding was the little corrections needed which I have had trouble with previously....mainly due to poor drift align and gears meshing...the guide star virtualy never moved, that's what I am more pleased with.
The FR was tried in multiple locations..first it was SCT - 2" focuser - FR - T -Adapter - T ring - Canon 350D.
Secondly I took the focuser off and had the same but straight on the back of the SCT cell....I also have some adapters and tried difference lengths of tube to vary the space from chip to FR...tried approx measurements bewtween 70mm to 110mm.....all very poor.
I did try the focal reducer with my C11 origanly and even though yes their was vignetting it was no where near as bad as this...also I forgot to mention it added a lot of Coma with my current set up.
On cloudy nights someone has tried the CCDT67 on 16" Meade LX200R with 11000 CCD and said it works perfectly and mentioned we should be looking at more refractor/RC type Focal reducers then SCT reducer.????
Ignore where the focal reducer is in these pics..that is just 1 of 5 different places I tried it.
i would like to see this one in a wide field shot.
