Thanks for the heads-up regarding Andrews - yes, the website does look like something out of the late 1990's!
I currently use the Bintel 30mm wide field in my SCT (which I believe is rebranded GSO SuperView) and find it quite good at f/10.
I want to try out something wider to get more FOV for the upcoming Lunar Eclipse in end-May. Was hoping to buy used in case it doesn't work well as I read some conflicting threads on Cloudy Nights etc. on the 42mm GSO with vignetting issues etc. Unfortunately can't afford the top-end Panoptics or Pentaxes
Still open to purchase if anyone has upgraded their long focal length EP and has a spare GSO 42mm SuperView available for sale
Glad to note that 42mm SuperView is a good match for the SCT though. If I don't hear from anyone in the next couple of weeks, I may end-up buying it new...
Thanks & clear skies,
GR
