Baader IR-Pass Filter 1¼" (685 nm)

When using monochrome (black and white) CCD cameras (like The Imaging Source, ALCCD5, etc) filters are needed to produce dcolor images.

The Astronomik LRGB 4 filter-kit was designed especially for CCD imaging, resulting in true color images, even when taking images with continuum or emission spectrum. This filter set is the best in its class.

The Astronomik Pro Planet 642, 742 and 807 or Castell IR-Pass filters are used to capture images in the near infrared light there atmospheric distortions are less evident, resulting in higher resolution when imaging planets or the Moon. Can be used with excellent results for Moon, Mars, Jupiter, Saturn and other planets.

The ZWO 1.25″ IR 850nm Pass Filter is suitable for IR sensitive cameras. You don’t need to debayer and get the full resolution of this sensor when use it with a color camera such as the ZWO ASI224MC or ASI185MC, because the QE responce  of sensor beyond 850nm is all the same (i.e. infrared light passes through the Bayer colour layer). So you can use a color camera as mono camera with this filter, just don’t forget to keep the WB_R and WB_B settings to 50 (no White Balance applied).
