7" F11 or 8" F10 Newtonians if I can be so inclined to set them up but usually 5" F8.9 and 4" F15 refractors

A very difficult question to answer as to an exact favourite, but for high resolution visual work, I tend to use eyepieces from TMB SuperMonos, Clave, UO/Baader HD orthos and Zeiss Orthos. Performance / value wise the HD Orthos are very good. I get very good results from these but it all depends upon which scope I am using. Wide field I like my 37mm NATO Konig and my 44mm Kaspereit. But have others I quickly grab for a casual view. If I had to nominate a favourite? Not ultimately the best performing but much better than many modern eyepieces are two a 18mm Erfle and an 18mm Symmetrical both bough when I was a kid from HW English I have quite a large collection so am spoilt for choice

Thanks for the information will investigate Stelledoppie.

Splendid thanks Mark Simon

Hi Mark, thanks for that, I have just bought one of these so will find someone to make me an adapter or I can have a go on my Dad's lathe, do you know off hand the thread diameter? I will search out a suitable bit of Ali metal. Thanks Simon

Hello Was the military EP easy to adapt for use in a focuser? is it being used in a 1 1/4" unit Thanks Simon

Maybe this would work out? I may get one of these so that I can use my old 1100/10.5 MTO Lens? https://www.teleskop-express.de/shop/product_info.php/language/en/info/p1752_Adaptor-from-M42x1-to-T2-and-to-1-25--with-compression-ring.html
