Hi there, I recently got a BORG 89ED APO F6.7 Refractor, which I plant to use for imaging too.
I had a search around for a flattener/reducer, but the original Borg-made stuff is already out of production, apart from being super-expensive too!
I've read someone here, also a Borg owner, had a success using Hotech universal flattener:
But that one is just a flattener while I'd need a reducer too.
Could anyone suggest a viable solution to this?
Any imput would be much appreciated, thanks!
