Changing Focuser
I am going to buy a new focuser for my AR-127L frac.
The new focuser will need an adaptor or a new end piece made up for my ota to fit as the Hexafoc 2.5" is 82mm inside diameter, not a size that I've been able to find.
So, my main question is does the new focuser have to be the exact same distance from the front lens as the old focuser?
What happens if l move the focuser further away?
Old focuser is damaged, not repairable and not available new.
I've googled these questions and can't find anything, maybe a trip to the library is in the cards
Thanks.
Rod
