Adapters to achieve back focal distance between camera lens and zwo 1600mm + EFW
Hi folks
In a world of pain trying to try out my 1600mm pro with a Nikon lens.
I picked up the ZWO Nikon adapter
I picked up an old Nikon lens with manual aperture adjustment ring
I've brought the spacing in as close as I can using a little adapter ring inserted in to the ZWO adapter and a male to male m42 adapter between that and the filter wheel.
It got me close, but I still needed to stop down to about f/11 before I could focus on infinity.
My last thing to try is a $60 m54 female to m42 male adapter if I can get one, but it would take out 2mm of back focus at maximum.
Is this a losing battle? Has anyone been able to make this work?
What's left of my hair is falling out.
Thanks in advance for your suggestions.
