Two weeks ago I met Al Lamperti and Joe Lamb up at BMVO for a night out under clear, transparent skies. I decided to try using my old but trusty Celestron C9.25 as the OTA in my astrophotgraphy setup to see how it would perform with a recently acquired Starizona 0.63x focal reducer/flattener. I chose M13 as my target and was pleasantly by the results.
