Alex, that was a very interesting post you made above regarding matching eyepiece design to telescope types. Do you have any original sources you could point me towards as it is an area I would like to investigate further. I didn't realise the superviews were basically an Erfle (which autocorrect seems determined to change to earful) Many years ago I had a 30mm Erfle, a big brass thing with the old RAS thread fitting, I think I picked it up second hand at Fullerscopes in London. I used it on my home made 6 inch F8 Newt and it gave very nice views. I also had an adapter and a selection of 0.965 Orthos which I used. Probably unthinkable now, but back then Orthos were the bee's knees!
