Quote:Hello Bob^^Exept for FOV, this ASPH is better than old Leica 20x-60x zoom?I'm considering to buy Leica's zoom now. My club member said that this ASPH has large FOV but the old one is better sharpness and contrast^^Is it right?For me, narrow FOV is not problem. I'm a sincere planet observer^^ My main target is Planet and Moon^^I use ball lens eyepiece which made by myself and ultra narrow fov(about 10 degree) is no problem to me.I want more sharp and more contrasty one^^My precious line-up is thisBall lens 4.4mm, 5.9mm, 7.3mmXO 5mmCircle V celestron 7mm ortho(this one is really sharp^^)Brandon 8 & Televue Plossle 8My plan is, If old Leica is same quality with ASPH except FOV, buy 2 of it and use it with my Nikon binoviewer^^Which one is suitable for me?

Quote:Bob, thanks for your enthusiastic report. I'm very glad my recommendation for the Leica ASPH zoom turned out being the right one for you. And remember: my main recommendation was for using it with your f/7 160FL. The better if it's also that powerful - in particular together with the powermates - in a fast Newtonion.
I've no affiliation whatsoever with Leica but as a German engineer I'm glad - may be proud even - that this famous name of German optics history has managed to survive into the 21st century. Unfortunately this is not the case for many other also famous names from the past.
Enjoy your fantastic gear.

Remarkable especially since the Leica is actually 60 degrees at 17.8mm. Thanks for the great report Bob, I posted a few days ago in another thread I had excellent results with the Leica ASPH zoom unbarlowed in my f4.65 with a Paracorr 1.
