On the weekend I purchased the 2" adapter for my WO 66SD refractor. The main reason was so that I can get great low-power wide field views using my 2" EPs. Well tonight I tried it out for the first time, but can't get any EPs to come to focus using my WO 2" diagonal in the adapter. I just can't bring them close enough to focus. I tried 6 different EPs (only 2 are 2") with and without barlow. I could only get EPs to focus using a 1.25" diagonal (which has a shorter lightpath).
So it seems that you can only use the 2" adapter straight through, without a diagonal. Not what I expected, and not exactly convenient.
I'm surprised that I hadn't heard of this limitation before, as I've seen the adapter mentioned various times in forum threads, etc. I was really looking forward to this configuration, so I'm rather disappointed. I guess it will still come in handy if I want to hook up my DSLR to it.
Has anyone else got this adapter, and if so did you have the same issue - or is there some way around it (I really can't imagine what though)?
