        Comments about Explore Scientific 3x Focal Extender - 1.25 Inch Barrel:

        I've been looking for something to use for planetary imaging that would yield better results than my attempts with various Barlows (I own four - 2x, 2.5x and 3x 1.25" and a 2x 2") and I was quite happy with the results the first time I decided to try imaging with the Explore Scientific 2X Focal Extender. I've included a photo of a portion of the Moon, shot with a Canon T2i, Celestron Astromaster 90 refractor, and the ES 3X EF. This is a single shot at ISO 400, 1/80 sec., f/33, effective focal length of 3000 mm.
