I have read that observers find that adding this accessory to their 35mm Panoptic greatly aids the utility of the eyepiece. I have a little trouble maintaining good eye position with this eyepiece and, for a few dollars, this looks to be worth a try.
Anyone have experience with this extender?
Here are the details at a US supplier:-
