Quick Overview

The mono CCD cameras are generally more sensitive than the color ones. Is it possible to record color pictures with these instruments? Optolong RGB filters set 31,8mm perform just this application: the technique (trichromy) is to take a picture (that will appear in gray scale) with each filter, and then, using a special software, add them to get the color image. To perform this, you need to use filters with advanced technical specifications, just our set is!

Details

Optolong RGB filters set 31,8mm is specially designed for color astrophotos using monochrome CCD cameras: in fact they offer a higher transmittance compared to traditional filters and a better defined transmitted band. These filters are parfocal and are manufactured with the highest quality standard: so when you change the filter to record another picture, you will not have to change the focus point of your telescope (they are perfect for use with filter wheels).

 

Photographic use: Optolong RGB filters set 31,8mm is designed to allow you to record color images with monochrome CCD cameras. In fact you can take a picture for each different filter and use a special processing software (indicating that each filter corresponds to one of the R, G and B channels) to obtain the color image (trichromy technique).
