This useful adapter fits neatly between the flattener/reducer and M56 threaded drawtube of the Skywatcher ED80, ED100 and ED120 focuser (so doesn't affect the camera's ability to achieve focus) and accepts regular 2" astronomy filters.

I purchase this as I introduced a 2" L-Enhance filter onto my .85 reducer, as without it I was unable to use the filter as the threads did not line up. It also minimally affected my back focus

It fits in between the .85 corrector/flattener and the linx astro M48 adapter on the focus tube but there is not enough inward travel to get focus. I was looking forward to using my 2" Optolong L pro on the 72 but as usual things never work.
We don't list the 72ED in the compatibility list for this reason. You are welcome to return this for a refund.
The latest versions of the 72ED have a shortened telescope tube to help with inward focus travel so this should work fine in versions purchased since late 2019.
