I never used this, I had a custom adapter made with a filter drawer.This is a combined pair of Gerd Neumann adapters which allow
connecting a Canon EOS camera lens to an astrophotography
camera having a female T-thread port.
The pair consists of:
1 universal eos ccd adapter plus
1 M48x0.75 to M42x0.75 (T-thread) adapter.
The URLs describing each are:
I measured the combined length of this to be 0.794 inches using calipers.
Please factor this into the back focus requirements of your specific
imaging system before buying.
Price includes PalPal fee. Buyer pays shipping.
