1. SFFR-70-2 .8X Reducer for 70 mm f-6 refractors

Why do you ask me to write a review if you dont post them?

Works well with SV70 ED & Cannon DSLR

Optically, the SFFR-70APO does exactly what it is supposed to do and does it well. As an added bonus currently, the focal length reduction allowed imaging of a greater portion of Comet NEOWISE.

All of my “back end” optics have been 1.25” up until now, so the heft of this 2” item was a pleasant surprise. As I use a DSLR for imaging, eliminating the 1.25” adapters makes for a much more solid connection between camera and telescope. Too bad that 2” filters cost so much more, but no one ever said that astrophotography is an inexpensive hobby.

If you pay attention to getting the proper spacing from the FF/FR to the imaging chip, this product will give you round stars all the way to the corners...at least it does on my ASI1600MM-Cool. This FF/FR is a must for astro imaging!
