42mm projector and photo eyepiece (2")

When doing afocal astrophotography special eyepieces might be needed.

The GSO 32mm and 40mm photo eyepieces are Plossl eyepieces but the eye rubber can be removed revealing a T2 thread. This T2 thread can accept many different adaptors. Using the proper one almost all of the cameras can be mounted and breathtaking images can be captured. Using a bayonett adaptor even DSLRs can be used.

The T2 thread distance can be adjusted, so the important camera lens - eyepiece distance can be finetuned, or using a DSLR the magnification can be adjusted slightly. Using the eye rubber the eyepieces can be used for visual purposes just like any other eyepiece.
