12.5" Meade,Discovery or equivalent quality with excellent coatings.
Need f4.8, but 12"-f5 or 13.1"-f4.5, etc. will do, as long as the F/L is close to 60". Will consider buying cell also (for 15" tube). Will also consider OTA, or complete Dob if price is not much more than the mirror, and if you are close to Birmingham, AL.
