I cam across sky rover 82 deg and 100 deg eyepieces. has anyone used these. From just the appearance, they appear to be similar to explore scientific eyepieces but ES eyepieces are Argon purged so probably they are more weather resistant.
I am currently using a 20mm 68deg eyepiece and like it better than the 8-24mm zoom or the celestron/orion plossles (13mm, 25mm, 40mm), so I want to try the wide angle eyepieces.. I understand ES and TV eyepieces set a benchmark but cant afford the nagglers and ethos.
