    Default Aspheric lenses



    There were a few discussions here about EPs incorporating aspheric elements. Browsing internet I stumbled on this article which I found educational.

    https://www.edmundoptics.com/resourc...pheric-lenses/

    Interestingly, aspheric lenses are manufactured from glass, plastic, or combination of both.

    Oh, and my favorite EPs incorporating aspheric element are Baader Hyperion Aspheric, which I feel are underappreciated for the performance and ergonomics they deliver in very compact and lightweight package.

    Yes, I agree big time Bigzmey!

    I love mine and often use them in 2" mode on my ST80. They are lightweight and give stunning wide field low power views. They're quite competitively priced in my country as well.

    Thanks for the link, Bigz. I was browsing the Edmund Optics site again a week or so back and they have a lot of optical info there. Also some nice video material that can be found on YouTube as well.

    We need to entertain when skies are cloudy, and you can only buy as much fracs and EPs.

    Do you favor the Aspherics in a certain style of telescope Bigzmey or use them with all your telescopes?

    I like them in all my scopes, SCT and fracs. But the most fun I had was with 150R at the dark site. Dark skies, crazy light gathering power of 6" frac and low power (24x) wide field (3 deg AFV) views. I saw many targets like I never seen them before that night.

    Anza hunt and Celestron Omni 150R first light

    Another night when sky cooperated I got the best ever view of Omega Cen with SCT and 36mm Aspheric.

    On the other hand newts and DOB users don't like them that much, so I would say fracs and CATs.

    Yes that's my experience across all three scope types, fine in refractors and cats no advantage with Newts.

    The article may be missing one method of making aspheric optical surfaces that is used in Russia: molecular beam epitaxy.
