Thanks for the suggestion of Explore Scientific's 100 degree EPs. I have found numerous discussions online and the general consensus is that there is virtually no difference between their performance and the TV Ethos line, apart from shorter eye relief, and they are indeed half the price.
Would that be a fair statement to make?
How do ES100s work with dioptrx? I don't know how dioptrx works in practice, I know it is a barrel lens to correct astigmatism, but do they have to screw into the eyepiece or like filters can they be put into a filter tube and then you can use any eyepiece you like, provided of course you have adequate focuser travel.
Do any Perth people have either an Ethos or ES100 I can check out, either at a star party or just to visit on a clear night? It sounds like the ultra wide eyepiece thing is liked by some and loathed by others, I guess I should find out which camp I'm in before I buy!
