Need to use 3 extension rings to reach focus -normal?
Hi,
This is my situation, I have a Explore Scientific 80ED . My second scope and first refractor .
When using the ZWO 178MC camera with this scope without the diagonal as was suggested to be better I need the two 2" Extensions supplied and an additional one which I am using part of the Bintel Projection adapter to reach focus. If I add a Barlow can't even get focus would need another ring.
I see others setups and this seems a little unusual to have it hanging so far back. Is this a characteristic of this scope ?
Appreciate any ideas,
Cliff
