Meade SWA 2" 40 MM.   Bought it for $125.00 on the Meade blowout sale a few years back.  Though that I would only use it as a finder eyepiece.  Turns out its a great performer in my SCT. 

That's my favorite as well.

But the O/P asked about 1.25  inch low power eyepieces not 2 inch.

I have the entire Meade 4000 SWA, and UWA, and love them.

However the 24.5 SWA is a little soft at the edges.

Can those of you that own the ES 24MM 68* tell me if it's sharp all the way to the edge?

 

Steve

I used a 24mm Meade 5K SWA for 1.25" only low powers but I prefer a 2" visual back with a 40mm WO SWAN.  Since getting an f/6.3 reducer, I still prefer the 24mm Meade though if I go 2", I like the 22mm Nagler T4 or 28mm Meade 5K SWA.  Any wider than that and the vignetting is complete, with dark edges.

 

None of these EPs are sharp to the edge without refocusing as the wide FOVs show some of the SCT's inherent field curvature.  Adding in the reducer/flattener removed 2/3 of the field curvature relative to f/10 with no corrector, but there's still a bit there.  Younger viewers can probably accommodate it and if I focus about 40% of the way from the center, I can see everything in focus.  There is little to no astigmatism in any of these EPs, maybe a touch in the Meade 5K SWA at f/6.3 but none at f/10.

I have an Antares 25mm 70 degree that I got from ScopeStuff. Inexpensive and works great!

24 Pan. Widest true fov for a 1.25" ep in an 8" SCT, Very comfortable ep to use, with or without glasses.

I have to agree. The 24 Pan gives terrific views in my 8se.

The longest eyepiece I have is a 32 TV Plossel but my favorite low power eyepiece for my 8" sct or my 4" refractor for that matter is my 28 Edmund RKE. It has a portal to outer space charateristic that I just love.

Another vote for the 24 Pan. I did buy a TV 32 Plossl and while it works nicely as a daytime planet-finder EP, at night there's nothing it does better than the 24 Pan, and I much prefer the latter. It's also my favorite low-power EP for the TV-85. I don't like using 2" EPs with either of those scopes.

The only thing that concerns me about the Pan is the tight eye relief. Astronomics lists it at a usable 11mm...pretty short for a 24mm of any flavor. Do you have to scrunch your eye really tight to see the whole field and is beaning a problem?

For me only light pressure against the unfolded eyecup is required to see the field stop all the way around at once. While I can force some blackout by really pushing in further there's no need to do that. It's an exceptionally easy and comfortable EP to use, for me anyway. Most of the rest of my EPs are Radians and I use the eyecup on those adjusted to a very similar feel that the 24 Pan has naturally. I don't use my eyeglasses when observing.
