Would I be better with a 2" or 1.25"?
Any thoughts on the this on http://www.myastroshop.com.au/guides...ar-reducer.htm or there's one at andrews on the Guan Sheng Acc. page.
Any thoughts/suggetions.

John...if you go to the ED127 yahoo forum in my sig then there are posts all about this.
But here is the guff for others....Explore Scientific are just about to beta test a new dedicated 2" FR/FF and a 3" FF.
They tried this around 2 years ago but those units failed testing so this is the "back to the lab result from them".
I spoke to one of the guys who is going to do testing (and to ES). He Knows of it but doesn't know when he'll get one to test. I believe (I could be wrong) ES has them built already and are awaiting this testing to release them. ES told me of the 3" FF unit.
Ok a 2" FR/FF will be restrictive but better than nothing. A 3" FF...hmmm I'll have one.
Hope this answers the question...oh and other FR/FF don't work 100% well with this scope (IMHO) but there are quite a few FF that work ok.
