Does anyone know how I can put an IR blocking filter on my ASI224MC with the 2.1mm lens that comes with the camera?  Wanting to do allsky and have the greens come out correctly.

Interesting challenge, incorporate a cheap 2 inch filter in a custom dome maybe?

ZWO sells replacement windows for their planetary cameras.  I cannot find a link for Astronomics, but Agena Astro has them.

I looked on another site and only found the larger ones that were not for my camera.

This one will work!

 

Thanks

This doesn’t work.

The wide angle of view of the lens means the edges of the field are looking at an angle through the filter. Which band shifts the filter resulting in strange color gradient vingetting.

Did you find any solution yet? I'm facing the same issue...

You need one of these to replace the one in the camera.
