Just thought I'd mention the 70 degree Explore Scientific eyepieces you see around are considered "starter" eyepieces and don't possess the same quality as their 68, 82 and 100 degree lines. The 70s were included in new scope packaging just like Celestron or Orion would include with their scopes. Woodland Hills sells them and they range from $39.95 to $69.95 for the 2" models. Just thought I would mention for those who are unaware of the difference.

A few months ago, I purchased the 35mm ES-70 from OPT, they were closing them out for $50 and I needed a 2 inch Widefield to loan to someone.
Going from memory, I would recommend it over 2 inch eyepieces like the GSO Superviews. It's surprisingly heavy, over a pound if I remember, it's got some glass in it and it seems nicely made. It's sharp in the center but of course in a fast scope, it shows a healthy amount of off-axis astigmatism, it's no 31mm Nagler, 35mm Panoptic nor even a 32mm TV Widefield.
