WebMay 4, 2024 · Altogether I believe that it will not produce that much aberration if I am only constricting the wavelength to 656 or 500 nm. I have been looking at a few scopes from Celestron and Explore Scientific that are around 100-150 mm in size. If anyone has used achromats for deep sky narrowband imaging any help or information would be great.
