    SCTs are slow scopes (f10) and not all that fast (f6.3) even with the reducer/flattener, so you should find that even budget designs work well.

    For long focal length standard AFOV 2" eyepieces, everything I've tried has worked well, including the budget designs - you don't need fancy designs to get good results.

    For ultrawide AFOV eyepieces, the televue Naglers (and, presumably, ethos) will work brilliantly in just about any scope, including SCTs... I've managed to pick up a couple of 2" Naglers used over the years...

    The William optics UWANs also work well - I have the 28mm, which is a big chunk of glass (my only eyepiece so far with a noticeable cool down time) - I also have a budget 30mm 80 degree eyepiece from moonfish (probably a rebadged Chinese made one) - which is a little soft at the edge (and suffers a lot more in a fast scope, although the centre remains OK) - but works amazingly well for something around a third the price of the UWAN.

    I haven't come across the ES eyepieces here in the UK, but they get good write ups from people who have them.

    What do you want to view through the eyepiece, and why do you want a 2" one?

    Which one is "best" depends on whether you want to view planets or DSOs, as well as on personal preference and budget. There is no advantage to a 2" barrel except that it allows a wider field of view on long focal-length eyepieces.

    The 8SE comes with a 1.25" diagonal, so you would need to upgrade the diagonal before you could use a 2" eyepiece.

    Hi,

    The range of 25mm to 40mm is about all you can do in 2inch with SCT.. had a 56mm and sold it as it had large dark area in center from secondary..

    I have been using some Meads that have been on sale recently.. and very happy with the 40mm Mead 5000 60 degree view..
    Meade 40mm Series 5000 Plossl Eyepiece - 2"(D) - OPT Telescopes

    The 40mm is much better than the 32mm... But it is giant and heavy... Size of 8 oz water glass.

    Its disconinued but you can still find them butr as keith said you first need to invest in a good 2" diagonal..

    With my 11" and 8" I use the Ethos 21mm to 6mm in two inch but then I also use them on my much more demanding refractor as well. And the FOV does make you feel like you are swimming in space.

    That said with a good SCT I would recommend the Explore Scientific 82* 18mm and 24mm or 30mm. I used the 18mm quite a bit when I had it for wide field stuff and rarely the 24 mm for the super wide field. For the price the view is very very good and you get the swimming in space feeling as well for 1/5 the cost of a Televue.

    If you look at cbrucker's signiture and mine you will notice somwhat simular equipment. My Naglers were bought for the APO it just wows you with high end eyepieces. The 8" Celestron is not inferior just different being an f10 compared to f8 for the APO. A 9mm is about the max in the SCT on ok to good nights and a 4mm in the APO. As the numbers go down the price goes wildly up for viewing. Unless you are imaging do not be put off by a scope that is slow f9 and up, they are great for viewing and do not demand nose bleed priced eyepieces. Getting back to your question my Nagler 82 deg eyepieces out perform the Meade QX's in the Celestron 8" SCT ( yes I have a 2" everbrite diagonal on the SCT). The Meades compete very well in the SCT against the Naglers for 10-20% of the price Yes the dialectric 2" mirror is better than any 1 1/4", and 2" diag is needed for any 82deg over about 20mm. I have not tested 100deg eyepieces in the SCT they are out of my budget. It does well with 68deg up to 36mm, and 82 deg up to 22mm. Beyond those I do not know. Quality 68 deg eyepieces are down right cheap compared to 82's and very nice in the SCT. Quality 82' are just over half the price of 100's. Hope this helps.

    Instead of BEST EYEPIECE I would ask what is the most "useful" FOCAL LENGTH 2 inch eyepiece...In my own case using m C8 and C11 my inexpensive Proxima 31 mm seems to be in the diagonals more then my 26 35 or 41 mm 2 inch eyepieces on most nights...But that's me and since I sold my few Naglers and converted over to 68-70 degree eyepieces for "comfort" reasons you may enjoy a 35 more.

    The difference visually between my Panoptics and the cheaper Agena , Hands on Optics Proxima is very very small visually ..so from my experience you sure do not have to spend serious money to get good views...

    I bought a set of Orion Q70 70 deg eyepieces but the weather has been horrible and I haven't had a chance to try them out yet. They got very good reviews when used in the slower F8 - F10 or more scopes. At $99 ea or $249 for the set of three, 26mm - 32mm- 38mm, they are a real bargain. Now if the weather would just clear for one night!!!!!!!!!
