The 2″ IDAS-D2 LPS filter for use with my William Optics Zenithstar 61 refractor telescope with a Canon 5D MkIV camera.
This is a quick play using the IDAS-D2 filter on the Canon 5D MkIV camera and a Canon 100mm macro lens to see what the colour cast was like in diffused daylight.
The filter bandwidth rejection ranges can be seen below;
For info, I used a standard M58-M48 stepdown ring to mount the filter to the Canon macro lens and I think that configuration will work for normal DSLR night photography with the Canon lens without any significant vignetting.
In the ‘real’ world the IDAS-D2 filter is performing very well
