    Default New ES 52 series coming soon



    So, I actually seen this originally posted elsewhere, (cough cough), but looking at Agena's site seems to confirm the rumor. A new Explore Scientific 52° series supposedly to arrive late summer from what I read. Stated to have generous eye relief to boot, so they're definitely not of the standard Plossl configuration. I'm anxious to see the new arrivals and learn more about their design.

    My current EPs FOVs are 100°, 82° and 60°. I've found that after using the 82° it's difficult to go back to the 60°. I'm curious what the advantage of an FOV of 52° gains you, unless it is purely a cost (read low-cost option).

    Cheers,

    I would venture that from the ES marketing side of things if would be to offer a Plossl like alternative in a more user friendly package. One of my first thoughts was this seems similar to the Vixen SLV lineup.

    Interesting! In ES style eye relief is not fixed, but varies from 15mm to 27.1mm. Depending on weight and top lens design I may pick one or two.

    That was my first thought also Frankie, did someone get a licence on the SLV? or will they just look suspiciously like them...

    Compact size, light weight and plenty of ER (20mm) - this is what attracted me to Vixen SLV line. Lets see where ES will stand.

    Whaaaa??? You're not suggesting we may be seeing imitations or copies of designs in the Asian telescope market are you?

    The wide field views don't really add much when you are looking at small compact objects. Planets, small galaxies etc. They could be an interesting addition to planetary viewing giving ES usual build quality.
