    Default What would be the best eyepiece to get?



    My current eyepieces are the Explore Scientific 82 degree 14mm, Explore Scientific 68 degree 24mm, the Orion deepview 28mm, and a 10mm plossl with a cheap orion barlow. I want to upgrade both the 10mm and the 28mm. The 10 is ok, but I feel like the 11mm 82 degree explore scientific would be way better. The 28mm in my opinion is not a very good eyepiece and I was thinking of getting the 68 degree 34mm explore scientific. I would be happy to get both, but at the moment I will only be able to afford 1. Does anyone have any recommendations? I mostly view deep sky objects, but I use fairly high magnification on globulars and planetary nebula, the 34mm would be for open clusters and bigger objects like m31 or m33.

    The ES 82° 11mm is an excellent eyepiece as I noted in your other thread. In my dob (12"), it serves in excellent capacity on galaxies, globs, PN's, and even works well on planets, but at 138x (in my scope) the planet views are small. I typically push up to my 6.7mm for planets, or on nights of excellent seeing, my 4.7mm.

    When I first started out, I used my 30mm (GSO Superview) that came with the scope extensively, even bagging the entirety of the Messier catalog with it.

    As I've progressed and evolved into more of a galaxy hunter, I typically stick within a range of 84x to 173x represented by the ES 82° 18mm, 14mm, 11mm, and 8.8mm, with occasional assistance by the 6.7mm. These all work very well for my observing habits, my eye, my backyard, and my scope. Using this team of eyepieces, I've logged (as of Monday night) 809 galaxies.

    That said, my ES 82° 24mm and 30mm, especially the 24mm, serve well in low power wide angle views of open clusters and the larger nebulae (the North America, Eastern and Western Veil) or to just take in the vast star fields along the plane of the Milky Way, or to take in the true expanse of M31 at a dark site.

    Since you've made inquiries in another thread on the possibility of upgrading to a larger aperture scope, such as a 12", you would do well to keep a future scope purchase in mind while eyepiece shopping. Plan for the future as it were.

    The ES 68° series is well regarded also, though I have no personal experience with any of these. And of course, you won't go wrong with anything with those green Televue letters on them. Awfully pricey though.

    So as a fellow DSO hunter, with my scope, the 11mm sees a lot more focuser time than either the 24mm or the 30mm. I find it to be of greater utility. That's just my​ experience with how and what I observe. Don't know if that really helps you or not...

    I have the ES 34mm and it's an excellent eyepiece in all 4 of my scopes. The 11mm is rated as one of the best ES eyepieces and mine gets a lot of eyepiece time on my scopes. The ES 28mm is a very good eyepiece and I have one. I just don't have much time with it, clouds and rain!!! They all show up on the used equipment forums quite often and for very good prices.

    I am leaning towards the 11mm. I researched it after your post on my other thread. It seems more practical both cost wise and the use I would get from it. I would love the explore scientific 34mm, but I would only use it to find objects(especially large faint galaxies and nebulae). Maybe on down I can upgrade and btw congrats on 809 galaxies that is a huge number as I have only been able to see about 4(m31, m33, m81, m82).

    When Virgo and Coma Berenices come back around in a few months, indeed even Ursa Major and Leo, your galaxy tallies will grow considerably. Between those four constellations, I've nailed down over 300 of them.

    Also, you might consider the forum's Messier Visual Award program: Astronomy Certificate Visual Awards Program Apply Now!!!

    Loads of fun to work this list, and it really serves to hone one's observing skills. Good stuff.

    Thats going to depend on what sort of scope you have. On my SCT - 10mm just dims everything too much. On a dob though it is a good high mag option

    If you're getting the 12" dob (manual) you'll want a reasonably wide field eyepiece at approx 10mm focal length. The 11mm ES82 seems to be fine in my f/4.9 12" dob but still yet to put it through its paces... I didn't notice any optical aberrations with it but perhaps the scope you're after may have a faster focal ratio? The other other options I'd suggest would either be the TV Delos 10mm or the Pentax XW 10mm - both premium eyepieces with a premium price to match

    This is a great and comprehensive thread on observing DSOs and includes a post on choosing the right EPs.

    A Treatise on Optimizing DSO Observation

    Basically for low power you want something that will yield an exit pupil between 5mm & 7mm, but you probably want to determine your maximum pupil diameter first. Combine that with a 82 degree AFOV EP and you're set.
