Product Info
Manufacturer Description
The Tele Vue 41mm Panoptic eyepiece is a big brother to the 24mm Panoptic (largest 1.25" field). With its 46mm field stop, the 41mm Panoptic delivers the largest 2" field possible. An adjustable and removable screw-type top allows quick, comfortable eye positioning. The scalloped shape gives a positive grip.
The Tack-Sharp, Long Eye-Relief 68 degree Field Eyepiece
With the Panoptic series, Tele Vue has taken the Wide-Field concept to Nagler-like performance levels - A meaningful advance over any eyepiece in its 68° field class.
All Tele Vue Panoptic eyepieces have proprietary tuned full multi-coatings, blackened lens edges, high index glasses, fold-down eyeguards, rubber grip rings, cover for the eyeguard, an undercut in the barrel for extra locking security, and filter threads. All Tele Vue eyepiece lines are proprietary, in-house designs manufactured to their specifications and tolerances. Every eyepiece is individually tested at Tele Vue to ensure it meets high optical and cosmetic standards.
Concept: Using my Wide-Field design as a starting point, I looked to bring Nagler-like performance to the 60+° field class with the Panoptic series. The idea of a lens to "interface" between the eyepiece and Barlow struck me as the proper way to keep size, weight and cost to a minimum while improving edge of field performance even further. I later developed this idea into the Powermates. — Al Nagler

Televue Panoptic 41mm Eyepiece
Pros:The widest FOV in a 2" format; black background; very well manufactured.
Cons:Heavy at over 2 pounds; expensive; balance problem on small scopes.
Comments:I had an opportunity to borrow a Panoptic 41mm eyepiece the other evening for some viewing in my f/10 SCT and was very impressed with the results.
Bottom Line: Would you recommend this item? Yes
This eyepiece delivers the widest possible view in the 2" format, with excellent contrast and a view that is sharp to the edge of the field - very nice considering this is one very big and heavy eyepiece. It was not a problem weight-wise with my SCT but it could cause some balance problems with a smaller telescope.
I had no blackouts even with the 27mm eyerelief, but I had to place my eye right up to the glass. Stars were pinpoint right to the edge while star hopping and I didn't even see any pin-cushioning/sea gulling. If you want the very widest FOV and are willing to spend almost $500, this eyepiece will deliver. You may rather go for the 35mm Panoptic which will cost less and have a nice field of view, but either way this is one very nice eyepiece. You can remove the rubber eyecup for eye positioning if necessary but I didn't need to.Sort by
