Does exactly what its supposed to
Friday, 13 August 2021  | 

So much easier to change filters during an imaging session with this. Pricy for what it is, but its well made and very useful. Worth considering an extra filter holder too, to avoid threading/unthreading the filters in the dark

Nice little filter holder

A nice, well-made filter holder. The drawer is held in place with two magnets, but also with a spring-loaded pin in the side of the holder, in line with the drawer knob. This pin can be adjusted in and out with an Allen key, which alters how much it holds the drawer in place. If you're having problems putting the drawer in, you might want to back off this pin a little!

Excellent service, and the filter drawer is excellent, makes it much more simple to swap filters than having to dismantle the optical train.

Excellent addition to imaging equipment

Bought to enable a quick change of filters without having to disturb the camera. Extremely well made yet light and easy to fit to either DSLR or CCD. Allows easy change of filters during an imaging session. Holds the filter securely. Nice anodised finish.

Good, but...

I've had to put a rubber band around mine to stop the drawer falling out during telescope slews. Turns out the magnet isn't so strong after all. Yes, there's a lock screw, but on my set up that's inaccessible unless I remove the camera, which defeats the purpose of having the filter drawer in the first place. But I can live with that - this is a very useful accessory.

Perfect, as im a osc user, this is all I need for changing out filters without upsetting the imaging train, especially if youre in the midst of a session out in the dark. Product is nicely engineered complimenting the set up.

Simple, headache free item.

I own two 2'' filters and wanted simple solution for filter swapping. Traditional filter wheel is to expensive and simply not necessary for my requirements. This drawer solved problem immediately. Fantastic build quality, easy to use. No light leaks. Highly recommended.
