The filter does as intended, however the service from FLO was outstanding. The filter was in the post within an hour of ordering and arrived first thing next day. Thanks FLO!

Arrived well packed as usual ,sensible price does the job .

Works well on my CMOS camera and a decent price

A must if taking any frames or just viewing anything that includes vegetation. Very satisfied with results.

Great Filter , just what I needed. Another first class service from FLO.

They work fine, would recommend.

I bought this filter for my zwo asi294mc pro as the 2 inch was out of stock. I fitted it with the attachment that came with my 294MC pro and dfit tight up to the lens, I still get a bit of vignetting in the corners as the sensor is bigger but this can be calibrated out with flats. It makes my final processed image much more sharp and contrasted, so we'll worth the money and does all the more expensive ones do.

Appears to work well when used for imaging planets. However, I wanted to stack with a UHC filter for deep sky imaging and the internal thread mentioned in the description for this purpose wasn't present on the 1.25" version I got as a package with a ZWO camera.

Excellent experience..easy and quick transaction ..thanks

Looks great. But when fitted to my ZWO 224mc it will not fit into my Celestron 1.25" light back. It's just .5mm too wide. Perplexed by this.
