360degree rotator for lunt 50mm double stack

Post by Bill_C »

Hi All,
I am a fairly new member to this group and enjoy the images posted by the more active members. I
have a new to me Lunt 50mm scope and have recently added a front etalon to double stack with, I
am wondering if there is a dedicated rotator for this application?
Thx Bill

Not that I am aware of.

Making gaskets out of paper and stacking them between the threads of the outer etalon will allow you to offset the relative offset. This is what I did with my Coronado DS90.
