Hello,
I had thought about the baffles refractor V reflector and I am guessin' that the baffles are there to collect scatter caused by the lens in a refractor. So, not stray light per say but induced scatter by the front lens.
(Pretty much is due to costs, difficulty and being lazy. Baffling the mirror and the focuser cage components seems to be the extent of major gains as well).
Good point about airflow, it had been creeping into my design thoughts a bit, but the idea of easy baffles was all consuming apparently. Certainly tube flow should come first. So unless the baffles are removed from the apex of the tube to allow for airflow I think I'll go backwards.
I'm running NftW with the dew shield on, and had the tube at 230mm which is the same a GSO D8F6. With the dew shield set to 200mm in front of focuser, I am getting baffles from 224mm at the opening to 202mm at the mirror face.
gives me something to think about in smoothing at least... Thanks for the replies.
