Do I understand correctly that I can fit in about 50mm of backfocus if I screw the Hyperion Zoom directly to this prism with 2"/2" Inverter Ring – #1508020? Or am I misinterpreting the "optical length" value?
Unfortunately, this only works with 2" mirrors. This is because the housing of a 1.25" prism is filled with the glass of the prism so that the lower part of the eyepiece cannot penetrate the housing.

have this eyepiece and Skywatcher 150p with 2" focuser and about 45-50mm of lightpath to spare. I really want to save my neck and use sky diagonal or a mirror. Is there any way to stick this eyepiece to Baader mirror/diagonal without resorting to glasspath correctors with my constraints? Which one do i need specifically?
We are very sorry, we are not aware of any possibility to connect our Hyperion Zoom with a zenith prism to a Newtonian with so little backfocus. The reason for this is that a focal length extending element such as a glass path corrector or a Barlow lens cannot be mounted at the necessary point in the beam path. This element would have to be mounted directly in front of the secondary mirror.
