I have a FLI CFW 4/5 filter wheel in good condition with 50mm square Astrodon Gen 1 filters and a 6nm Ha filter.
The LRGB are in good condition. The Ha has a small chip on the top corner. It still works fine even with a 16803 sensor as it flat fields out. But for anything smaller than a 16803 (which is everything right?) it won't even come into play.
New these filters are worth a lot. Together these all cost around AUD$5500. These are used but in good condition.
The FLI filter wheel can be used with any camera as it is controlled independently from the camera. I use a FLI filter wheel
with a ZWO camera, QHY camera, Starlight Express camera.
Astrodons are parfocal and also 1:1:1 exposure so no need to take longer exposures of one colour over another. You can also focus with the luminance filter and the Ha will be in focus. This is very convenient. I used these filters successfully with many different setups.
$1,975 + postage.
