So I need to make a new UTA external baffle for my scope (25"f4 Obsession). Currently I have a "thumbnail baffle" that extends 14 1/2" above the UTA, that covers 1/3 the circumference of the UTA, placed opposite the focuser. I am contemplating shortening it a tiny bit, but making it go all the way around the UTA. If I put my eye at the very bottom of the focuser and look all the way up, I can see just the tiniest bit above the baffle when it extends 12 1/2" above the UTA, so I'm thinking of making my new one 14" high AND having if goe ALL the way around. So two questions for y'all:
Would I gain any advantage by making it higher?
Do I gain any advantage by making it go all the way around the entire circumference of the UTA?
While I'm interested in any info on the subject, I would love to hear from people who have tried different forms of UTA external baffling.
And yes, the entire UTA is flocked.

Thanks for your help,

Josh Wright.
