I am setting up a new to me STF 8300/FW8-8300/OAG-8300 and noticed the mirror in the OAG has a few scratches on it (two kind of significant). Will these be a factor and mess up the guider image, if so are replacements available? On another subject, what kind of cooling performance should I expect from the STF? (I usually run my Apogee and QSI 8300's @ -30, 50-60% power) Thanks Paul
Make sure there isn’t a protective plastic film on the mirror. But don’t scratch it trying to determine that! Regardless it shouldn’t have any impact on guiding. Standard version cooling delta is about 35C.
