1.25 inch UV-IR cut luminance filter for CCD astrophotography, planetary imaging
The ProStar UV/IR rejection filter is specifically designed for use with modern CCD cameras where no UV/IR blocking filter is installed. With hardened optical coatings and high polish finish this filter blocks all wavelengths longer than 750nm. The UV-IR Blocker gives you a perfect parfocal filter for the luminance channel. It is also great as a dust protection for your telescope and camera
This is essential for maintaining true colour integrity when doing tri-colour imaging with monochrome CCD cameras and avoiding bloated stars.
If you're practical about your budget and want a filter that can do just what the others do, then the ProStar UV/IR cut-off (used by many established amateurs) is a great choice.
Screws into standard 1.25-inch threaded camera nose piece or eyepiece barrel.
