    Default Are these EPs a good match for my scope?



    I plan on getting the Orion 14" Intelliscope (f/4.6). I've read that fast scopes like that need a much higher quality eyepiece than slower ones. I can't afford the "top of the line" stuff like TeleVue. I have tentatively selected Explore Scientific's 82 degree 6.7mm, 11mm, 18mm, and 30mm, (plus an Orion shorty barlow). Are these EPs up to the task for this f/4.6 scope?

    Explore Scientific stuff is just great, maybe not quite TV quality levels, but top notch in anyones book.

    The ES 82's are very good EP's and should work fine in your scope.

    Thanks. That's good to know. I'd seen a lot of good comments on them, but they were all from people with 8" to 12" scopes. Needed the re-assurance for such a $$$ purchase.

    Those should be excellent for you. Take your scope to a star party and borrow someone's TeleVue to compare with your ESs before deciding to spend $600.

    Hi mjw,

    I have recently gone over to the ES82deg range of eyepieces to combat the coma issue with my newt/dobs with focal speeds down to f4.68 in my 64cm(25.2") and f4.4 for my 11.4cm(4.5") and these oculars are also great in my 14"f5.07 dob. I couldnt afford TV naglers either so ES was the only way to go if I was to obtain high end performance for mid range cost. (Have to admit though to buying into an as new second hand TV Nagler 20mm T2 a few days ago.) Good eyepiece performance makes one hungry for more of the same.

    You would not regret investing dollars in any of the ES82s. My favourite is the ES82 30mm 2", but the others I have are great also.

    Best regards

    2" -- Wow, with looking at so many different brands, I had not noticed the 18 & 30 were 2". I guess that means more $$ for both 1 1/4" AND 2" filters.
    I suppose I will also need a 2" Barlow for these 2" EPs?

    I think you should get your scope and use it for awhile with what you got before accessorizing. You'll be able to tell what you need or want after a few nights. I've got 7 eyepieces and a barlow. I probably use 3 of the eyepieces about 99% of the time. The rest barley get used and I don't use the barlow very often. I also have various filters that rarely get used. I think I remember you said you were interested in nebula filters. Once again, I say wait and see what you need. You will be able to see a lot of nebula with a 14 inch scope without a filter. I can see many with a 5 inch scope so you should be able to see way more than me.

    I also think you'll be impressed with the Explore Scientific eyepieces. I've looked through one in a 15 inch dob and they hold up nicely.

    The scope I expect to buy is a "build your own", so it doesn't come with any accessories - I have to choose them. If I buy them at the time I buy the scope there is a 20% discount. With the price of these things, that 20% mean a lot of $. Therefore, I'm trying to anticipate what I will most likely need/want right now.

    Please correct me if I wrong: Since nebulae are best seen with low power it would be best to get the 2" UHC filter (for my 30mm) and forget about 1 1/4" filter for the others?
    As for the moon, I was planning on a variable polarizing filter - but I don't want to buy both 2" and 1 1/4". Do you typically view the moon best with low or high powers?

    The moon looks the best at high powers. If you want the polarizing filter I'd get the 1.25" version. Nebulas is a bit tougher. You probably won't look at nebulas much higher than 100x power. So whatever eyepieces you're planning to get that will yield around that mark, get the matching size nebula filter. Personally, I would leave the 18mm ep, which would only give you 91x, and get the 14mm 1.25 ep which would give you 117x. But that's my opinion.
