Unmatched optical quality and high efficiency hardened multi-coatings result in the sharpest and highest images possible. Review: M51 ZWO ASI585MC - Love it, works great on galaxies, ZWO ASI585MC fits perfectly. Color calibrate in seconds. Review: Great for the Celestron Origin - Got rid of a lot of red noise compared to the stock clear filter that came with my Origin imager. Helps with star bloat as well. Approximately the same number of frames in 2 examples. Not sure if it will come out well posted here, but the bottom is the Optolong and there is much less noise in those. ## Features - 1. 96% transmission at 486nm (H-beta) 2.95% transmission at 496nm (OIII) - 3.92.5% transmission at 501nm (OIII) 4.98% transmission at 656nm (H-alpha) - 5. pass from 450 to 520nm and from 620nm 6.Entire Blocking of annoying wavelengths - 7.Ideal All-round Deep Sky filter even for small telescopes 8.Not sensitive to humidity or aging - 9.Scratch-resistant - 10.
