      5.0 D&G 5"F12


      Excellent optics. Great contrast!! Planetary and lunar awesome


      Need a capable large mount. Big refractor


      I owned a D&G 5"f12 ota made for me by Barry Greiner of D&G optical. Barry installs his optics in oversized tubes. According to Barry the larger tube facilitates quicker cool down and less interefering distorting heat waves in the optical path. He is definetly right on that aspect. This is a BIG Ota. This particular one did not have the newer astrophysics focuser, but the focuser as supplied was more then adequate. Opticaly the scope was outstanding. False color was seen only on the brightest of objects like Sirius and Vega. Very subdued even on Venus. Planetary images were incredible, Jupiter and Saturn appeared like mini hubble photos!!. This OTA could easily handle 60 power per inch and more on days of excellent seeing. Barry makes the BEST achromats, PERIOD. At the time I had a super planetary 12.5F6.7 dob that I made and won first prize at Stellafane for optical. So the D&G was being used less and less. Regretably I sold that fine scope, and have been kicking myself since. If you are looking for a real refractor, and don't mind the size, give Barry a call and I am sure you wont be disappointed!!
