About this product

Model:  ae_sw_ed_m56_filter_cell

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.

Not for ed 72 ds pro
Wednesday, 19 February 2020  | 

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.
