ZWO FILTER DRAWER M42 V2

Nice piece

Works as expected, good quality, perfectly sits in the image train, it is really 21mm, no need for additional spacers if used with ZWO cams + zwo adapters. Magnet is very strong, no need to lock in. I am very satisfied with the product.

Nice Piece of Kit

Very well made and sits in the optical train very nicely, changing out filters is a breeze.

Very handy.

This seems to work well. Just enough tension from the magnets to hold the filter in place even when upside down and not too fiddly to get the filter holder in and out. I have been using it to hold a 1 1/4 Astronomik UHC filter in place in front of the ASI294mc pro (with the 1 1/4" adapter) to help cut through a bit of the sky glow and reduce a bit of star bloat. I'm finding it to be an essential bit of kit in my image train. Also, I don't notice an vignetting using the 1 1/4" filter in front of the 294mc.
