StellaLyra 20mm 2" 80º Long Eye-relief, Ultra-Wide Eyepiece

Premium eyepieces manufactured in Taiwan. 

StellaLyra 80º long eye relief / ultra-wide eyepieces are manufactured to a very high standard by Long Perng in Taiwan. 

Fully multicoated, high-index, low-dispersion Lanthanum glass delivers exceptionally clear, sharp, bright views with excellent colour aberration control. 

All focal lengths have an eye lens and field stop larger than 30mm so are very comfortable to use and 20mm eye-relief so you can enjoy the view even whilst wearing eye-glasses. 

A useful M50x0.75 thread is hidden under the eye-guard so a DSLR or other suitable camera can be connected using the optional StellaLyra Photo Adapter.

Available in a range of focal lengths with 1.25" or 2" nosepiece. 

Includes two end caps and a bolt case for storage.

SL 2" 20mm 80° EP.
This is an extremely competent eyepiece, with great eye relief and sharp images right to the edge of field. I can't detect any off-axis aberrations, edge of field brightening or coma. A target is easily followed across the whole FOV and you don't have to peer 'into the corners' to see the edges. It's hard to find any negatives at all.
