  • 1 for the Vixen 4" refractor and Canon 400mm F5.6 lens (3mm bars).
I would order the larger size for each and then insert a home made foam ring to reduce the mask for the smaller tube in the OTA pairs above.

So far, my testing has led me to believe that I can use one mask per OTA either at prime focus, barlowed or with a reducer/corrector. Also, $82.50 doesn’t sound too exorbitant for such a crucial task as focusing, which we may perform several times per session over the life of the OTA. Worth every penny!

Cheers

OK then - send me your dimensions and I will draw up the template in CAD to send off - after i test some more

do you like the template or do you prefer the complete striated version of your own?
