About this product
Part Number: 20973
These ultra wide angle 1.25” eyepieces offer surprisingly good views. Good enough to bother more expensive brands!
The huge 82 degree apparent field of view, good field-edge correction and high contrast combine to provide a wonderfully immersive viewing experience.
Constructed with 7 fully broadband multi-coated lens elements in 4 groups. This together with edge-blackened optics and internal baffling provides bright, high contrast views.
Parfocal design means little, if any, refocusing is required when switching between the three eyepieces.
All have large eye-lens elements, soft fold-down rubber eyecups and 12mm eye relief.
Threaded nosepiece accepts regular 1.25” astronomy filters.
Weight approx 170g.
Note: These new eyepieces feature the same optics and coatings as the previous Nirvana models but have a slightly different mechanical design.

I have had this eyepiece for around a year now and it performs well in all my telescopes, including a short tube refractor, a Maksutov and an SCT. I particularly like it as a "finder" eyepiece in my small refractor, and as a lunar eyepiece in my SCT. It is a lovely size, giving a wide field of view (for a 1.25" eyepiece) while still being small and light. Another nice thing is it looks right at home alongside my Explore Scientific eyepieces which are very similar in style.
