    A great little scope

    I am using the 55FL with a QSI CCD camera and am thrilled with the results. It is very well built, easy to focus and yields wonderfully detailed images owing in part to the fast focal ratio of f/3.6. It holds focus throughout imaging sessions that often span 6 hours or more. I am very pleased that I purchased this little gem and look forward to many years of imaging with it. Highly recommended!
