Great Focal Extender
I bought this X 2 Focal Extender to use with my 1.25 eyepieces. It is mechanically a very high quality. It is excellent on most DSO. I have not had a chance to use it on planets yet due to the time of the year. I do notice a hint of light scatter on ...

Worth it for the price

Excellent quality, affordable accessory!
I recently got this unit and I am impressed. It is very multi-functional: I can thread it onto my 2" EPs for a ~1.7x magnifying factor, or use as a 2x with the stock assembly. Multi-coatings are very nice, and the fit and finish of this accessor...
