Compatibility with Baader UFC filter system

[Silent Running]

Has anyone encountered compatibility problems of standard filters with the Baader Universal Filter Changer (UFC) system?

I have the Filter base assembled with their camera adapter for wide T-ring and telescope-side M48 adapter, together with a couple of M48 filter drawers. It seems beautifully engineered but not cheap when fully assembled. The filter drawer fits nicely into the filter base when its empty. I then tried inserting my Hutech IDAS LPS-D2 filter into the drawer... no problem screwing it in. But then trying to slide the drawer into the base, I found that it gets stuck half way! On closer inspection I realised that the height of the filter means that it stands slightly proud of the rim of the filter drawer! Pics below.

Does anyone have experience of using other filters with this 'universal' system. Optolong? Triad?

I know this might sound daft, but is the filter screwed into the holder? On your first picture it looks like there are threads on the top of the filter however the writing is the correct way. Maybe you've not got something screwed into the filter by mistake?

I think the top of your filter should look like this.... so there is definitely something not right there. (I found this image on the internet)

Ohhh! Thanks for pointing this out! Yes you're right... I've got screw threads top and bottom. When I get home I'll check. How embarrassing if I've got another adapter screwed onto it!!!

Ian! You were absolutely right, and I've got egg on my face, hahaha, there was an adapter ring tightly screwed on to the filter!! After removing it fits perfectly! I can confirm if anyone else had doubts that the IDAS LPS-D2 filter is completely compatible with the Baader UFC filter system. Thanks again

Awesome! I'm glad I cam across your thread by change as I was searching for UFC info. Glad to have helped.
