    Default Next Steps



    When I receive my ES 82 18 & 8.8 later this week, these will be the EPs I will take afield.

    EP ---- Mag - Exit Pupil - TFOV

    30mm Zhumell ------- 41.67 -- 6.10 - 1.63
    18mm ES 82 ---------- 69.44 - 3.66 - 1.18
    11mm TV PLOSSL --- 113.64 - 2.20 - 0.44
    8.8mm ES 82 -------- 142.05 - 1.79 - 0.58
    5.5mm Meade UWA - 227.27 - 1.12 - 0.36

    My next step will be replacing the 11mm PLOSSL, and I'm thinking of going with this:

    13mm T6 TV Nagler -- 96.15 - 2.64 - 0.85

    Last will be upgrading my 30mm and I'm undecided between these two options. I was originally leaning towards the 24mm because of exit pupil, however I just got a new pair of glasses and asked the optometrist to measure my pupil diameter. She wasn't precise, but said it was between 6 & 7 and closer to 7, so now the 30mm is back in play and I'm leaning towards that choice.

    30mm ES 82 -- 41.67 - 6.10 - 1.97
    24mm ES 82 -- 52.08 - 4.88 - 1.57

    Any thoughts on the choice of the 13mm Nagler & 30mm ES considering my current inventory? With those additions my kit would look like this:

    30mm ES 82 ---------- 41.67 - 6.10 - 1.97
    18mm ES 82 ---------- 69.44 - 3.66 - 1.18
    13mm T6 TV Nagler -- 96.15 - 2.64 - 0.85
    8.8mm ES 82 -------- 142.05 - 1.79 - 0.58
    5.5mm Meade UWA - 227.27 - 1.12 - 0.36

    Those look like solid choices to me and a good range of magnifications for a variety of objects. I own the 30mm ES82 and it's a wonderful option for widefield low power viewing. The 13mm Nagler should fit nicely between your 18mm and 8.8mm and the wider 82* fov compared with the 50* fov of the plossl it is replacing will be noticeable. I don't own any Naglers myself, but I do own a Delos and it's the best EP in my collection. The 12mm Delos would also be a good fit for your collection, the Delos have excellent eye relief and they're on sale like the rest of the TV EPs currently are.

    I use and love all the T6 Naglers, but for less than half the price I may also recommend looking into the ES 82 14mm. If looking for Naglers I really recommend looking and searching the used market. They can usually be found at around 75% of retail.

    I would also say to hang on to the 11mm Plossl. You'll likely being going back to it for planetary and possible double star viewing. The FOV is a little narrower, but the sharpness and contrast is hard to beat.

    If you're thinking about the 13mm T6 Nagler, but would like more eye relief, then the 12mm Type 4 Nagler is worth a look.

    The reason I decided on a Nagler over the ES 82 14mm is I understand that EP was the weakest in the ES82 1.25" lineup. And yeah, my TV PLOSSLs aren't going anywhere.

    Eye relief isn't a problem for me. My glasses come off when I'm over the EP.
