    Default ES 82 30mm



    Well, I just ordered the ES 82 30mm so yall expect it to be crappy weather for all of Oct. (hahaha) I was torn between the 30mm and the 24mm. I was thinking, are there any nebulae and galaxies large enough to somewhat fill the view besides Andromeda, what else would the 30mm be good for. I read a lot of people love the ES 82 30mm EP so I went ahead and got it. Some examples would be helpful and much appreciated. I gotta 25mm standard plossl and love it but its only 52 degrees FOV. I thought the ES 82 24mm would be a lot better for me since I like the 25mm so much. Thanks in advance everyone

    I have the same EP but I find it to be a bit long for my fast reflector - it gives me a 6.4mm exit pupil, which under most circumstances is too big. I'll be trading it for a 25mm ES100 when/if it ever comes out. That's the same TFOV but only a 5.3mm exit pupil.

    Skaven, do you think the 24mm would have been better? What else would 30mm be good for besides Andromeda if you are in dark enough skies?

    Depends on the scope...the ES82-30 is perfect on a f/6 scope (5mm exit pupil). My scope is just too fast for it most of the time.

    I use the big 2 degree TFOV on andromeda, the Pleiades, the Hyades, the Veil nebula (with an OIII filter), the Orion nebula (with a UHC filter), M22, -- pretty much anything that exceeds 1 degree in size.

    I run mostly SCTS....and I own a 31 Nagler ..close enough to compare to the 30 ES and it gets a ton and a half of usage in both my C8 (65x and an EP of 3) and C11 (90x also with an EP of 3 ) and serves as a real nice ultra wide angle ultra low powered eyepiece in my as well as in my 100 mm f/6 refractor (20x and an EP of 5 ) which I use almost exclusivity for viewing open clusters

    Bottom line ..depends on the scope...
