Description

* Red, Green, Blue, and L (UV & IR-Cutoff) Filter set mounted in 1.25" (31.8mm) cells.

* Each filter blocks the IR, no additional filter necessary

* Transmission of nearly 100%

* Coatings protect amazingly well against scratching, aging, and humidity.

The transmission curves of the Astronomik RGB filters are optimised for CCD astronomy. Continuum radiators like stars and galaxies as well as objects that shine only in single lines (e.g. planetary nebulas), are reproduced in their true colours.

Because of the design of the band pass of the filters, the colour sensitivity of the human eye is optimally reproduced. You get CCD pictures that show objects in their optimal colours, just as if you would see it if your eyes were sensitive enough.



Each Astronomik Type II filter will permit colour pictures without an extra IR- cutoff filter, because all three filters are blocked near to the infrared (~1150nm).

All three filters have the same thickness, so that colour images between the singular pictures will be possible without re-focusing.

They are designed to work with nearly all CCD sensors available on the market. With these sensors and this filter set you will get pictures with very good colour balance.

* Astro- optimized transmission curves for images without colour shift

* Each filter blocks the IR, no additional filter necessary

* Correct images for very red as well as deep blue objects because of reproduction of the eye´s sensitivity

* Transmission of nearly 100%

* Same optical thickness for all filters

* Insensitive to high humidity, scratches and aging

* Glass substrate of very high quality. You get the sharpest images your scope can deliver Image shows Red, Green, Blue and IR Cutoff filter.

This package include the "L" Filter, which is offers UV & IR-Cuto
