I purchased this to add to my NightCat51 and a Nikon Z50--could not back focus Nightcat. Still researching. The unit would be perfect except for that. Was not given all info at time of purchase

This was purchased so I could change filters with a previously purchased filter holder. Unfortunately, the new filter drawer is a bit too wide to fit in the drawer. I’ll try and file it down, as not worth dealing with returning small item.

Was looking for a secure (mechanically speaking) method to attach my camera and a filter to an SCT without worry of it falling off. Since everything in the optical train is ******* in I now have one (as opposed to things that slide or nose in).
