Choosing a Focal Reducer

[nigelf]

I have a Meade ETX 105 and the Meade DSI PRO camera.
From what I've read I believe I could use a Focal Reducer.
Meade (and others) produce two - a 6.3 and a 3.3 reducer.
Which should I choose and why?
Grateful for all you help and suggestions. Nigel.

The standard meade/celestron F/R's have a sct thread but the ETX line has only a choice of 1.25" push fit eyepiece or T thread (from memory).  You will need to check that with someone from Telescope House but if so then your choices are more limited.  For a start I would suggest you checkout one of the dedicated ETX sites such as www.weasner.com for suggestions (you could also ask the chaps at TH if you're going to contact them).

Hope that helps
