Hi,
I just purchased a new 17.3mm TV Delos and am unable to thread standard filters (one color and one IR from different manufacturers) more than 1/2 turn into the EP barrel. The same issue occurs while trying to attach the filters onto a couple other TV eyepieces (24mm Panoptic and 3-6 Nagler Zoom). The filters fit all my older TV Plossls and Celestron Ultimas and some of my newer TV eyepieces.
Any ideas on what's causing this?
Thanks, Tom
