"Looking forward to trying the Coma Corrector when the clouds clear. Otherwise, wanted to improve my image spot for my full frame camera as my current smaller 2 inch coma corrector showed too much vignetting."

"Excellent performance on my 300mm f4 Newtonian using APS-C ZWO ASI 2600MM camera. Fits nicely into my Moonlite Nitecrawler 2.5"" focuser. Tight stars into the corners and very low vignetting at APS-C also the 70mm back focus is welcome for extra accessories."

I am very impressed with coma corrector. My equipment is 300mm f4 GSO truss newtonian, Moonlite 2.5" nightcrawler and a APC-S ZWO ASI2600.

Almost no vignetting and tight round stars into the corners. My 4 element GPU produces nice stars but this is another step up due to the larger diameter and less vignetting.

"Impressive optical quality. But be careful, a previous one bought had the lens mounted wrongly."
