The filter is not glued in, but unfortunately, sometimes threads get stuck. This may happen also with other adapters. They get even harder to unscrew when you grab them at the side, which can change their shape slightly.
We recommend to put them flat on a rubber mat (e.g. sponge rubber) and put another piece of rubber on top of it. Then put your flat hand on the upper rubber mat and rotate it - this way, the pressure is distributed on the whole filter cell, and the the two parts shut come off easily.

You can use
Reducing piece M48a / T-2i # 2958553
with an optical length of 0,7mm to mount the M48-ring directly to the MPCC. That's good enough, as the distance should be 55+/-1mm, and that close to the MPCC, vignetting is no problem, as the lens is smaller, anyway.
But please take a look at the Nikon bayonet or the adapter: The clear aperture of Nikon F-mount is relatively small, so that vignetting might be caused by the T-ring or camera body.

The Nikon Z-cameras have got a back focus of 16mm.
The Wide T-ring need 8,3mm, no matter if you use it with T-2 or with the additional S52 / M48 adapter #2958552

The MPCC requires 55+/-1mm distance, when used with T-2 or the optional Baader M48 Spacer Ring for MPCC III / Protective EOS T-Ring
# 2458405, or 57,5+/-1mm when used with the M48-thread, but without the adapter #2458405

If you use either T-2 or M48 with the adapter #2458405, you need an additional 30.7mm-extension (+/-1mm) in T-2 or M48.
For T-2-this can be done e.g. with
2x Baader T-2 / 15 mm Extension Tube (T-2 part #25A) # 1508154
1x Set: T-2 Fine-Adjustment rings (0,3 / 0,5 / 1 mm) - Aluminium # 2457910
or
1x Baader VariLock 46, lockable T-2 ExtensionTube 29-46mm with spanner tool (T-2 part #25V) # 2956946

For M48, we do not have the spacer rings yet, but you could use
2x M48 Fine-Adjustment ring 1mm (gold) - Aluminium #2457918
1x Baader Hyperion Finetuning-Ring, 28 mm # 2958228

If you use the MPCC without the optional adapter #2458405, you need a 33.2+/-1mm-extension - for this, we do not have a solution at the moment.

For a fullframe camera, we'd recommend the M48-adaptation because of its larger clear aperture.

We are sorry there is no other version available
