Although the product worked, it wasn't the best build quality. The threads are not great and didnt give confidence in it holding up my camera.

Due to the everlasting clouds in the night sky I have yet to use it in anger

Structurally well made. The T2 thread was tight but useable with the addition of a spot of oil. Not a problem as the assy. will be used permanently assembled but could be a problem if regular dismantling required

This is just what I needed to connect to my filter wheel to the Skywatcher 80mm field flattner on my Orion ED80
Tried using the Baader adapter before but the threads were too short causing the filter to twist off and also difficult to remove.
This one is a lot better
Plenty of thread so no filter wheel twisting off and a good grip on the outside ring making it easy to remove.
