I'm putting together a little grab and go kit with my WO 80 FD (555mm f/6.9), and I only have room for two eyepieces. Try to keep your suggestions reasonably priced, I know ethos's are amazing but I can't afford em. As a bonus if one of the eyepieces you suggest is small (physically small, not small in terms of focal length), you can also suggest a Barlow.
Thanks!

1. something like a 24pan/es68, or a 30 ultima or a nice 32mm plossl. 2. a zoom for everything below that (hyperion if you have the funds, or one of the cheaper 8-24s as "good enough for now")

Because of your short focal ratio, you could get by with just a zoom. I can recommend two price points...the Baader Hyperion 8-24 zoom or the Leica Vario 7-22 zoom. You get what you pay for with zooms. For planetary/doubles add a barlow.

I'd keep my 'naked' Meade 24mm S5K SWA and 8-24 zoom. The SWA is my finder eyepiece for all my 'scopes and spends more time in a focuser than any other eyepiece. The zoom is quite poor at f/l longer than 16mm, but is a very capable performer at the short end.
Having said that, I'd be bored of this combo in no time. I need variety.

David:
I have a WO 80mm Megrez ll FD, its a great scope. A couple of thoughts:
- these scopes have a 2 inch extension which has its own hole in the foam. I don't separate the tube from the diagonal, fit them at an angle in the space for the diagonal, it's tight but it works. It makes for an easier setup and frees up an eyepiece hole.
- A 24 mm Meade SWA works nicely and provides a reasonably wide 2.8 deg TFoV. If there room for a 2 inch eyepiece, that's what I would take...my 32 mm Televue Widefield is a good performer in this scope and reasonably compact.
For the other eyepiece... If you could fit two more plus the Barlow, I would say the Meade 16mm SWA or the ES 16mm, both are short and would likely travel together with the Barlow. I tried my 15mm TV Widefield, together with the GSO Barlow it fits my case.
I would add a 9mm widefield of your choice. I have both the 9mm Nagler and the 9mm TMB Planetary, I travel with the TMB.
Add the 2x - 1.5x GSO Barlow. And you would have a set that would cover the range from 20x to 120 x very nicely.
You could replace the 9mm with a 6mm, Barlow the 16mm to get 10.6 mm and 8mm and have an even broader range... But I like a 9mm and 60x...
A good zoom would work to but limit you TFoV.

Just 2 eyepieces (without a zoom) plus a Barlow is difficult thing given how short the focal length is of this scope. But if I had to would be:
28mm ES68 (or 24mm ES82 which will provide about same TFOV)
6.7mm ES82
2x Explore Focal Extender (2")
What you get from this is:
28mm - 20x - 3.5deg TFOV
28mm Barlowed - 40x - 40x - 1.7deg TFOV
6.7mm - 82x - 1.0deg TFOV
6.7mm Barlowed - 165x - 0.5deg TFOV
So gets you to s good lower planetary magnification that is still very enjoyable, and also lets you get a fairly good 3 1/2 deg TFOV for scanning with a 4mm exit pupil.

Double check on the above. 32mm Plossl, 11mmT6 and a 2x Barlow.

Your last comment may go a long way toward explaining why people continue to collect and switch eyepieces long after they've found every eyepiece they like and need.

Whew! Glad you cleared that up. I was beginning to think something was wrong with me

Wow thanks for all the good responses. I don't know if you noticed, but I didn't say which eyepieces I had right now, as I was hoping to get a really broad range of opinions rather than "ya that's good enough".
FIRST THANK YOU JON. I went back to my case and re arranged things, and your right! I can get 3 eyepieces in.
So the only decent eyepiece I have is a Celestron Ultima 35mm (49 degree AFOV), and I'm glad to see that similar eyepieces were already suggested. this eyepiece will give a similar FOV as an wide angle 24mm or 28mm eyepiece, but I miss out on the cool "space walk" feeling you get from the wide angles. Also, the exit pupil is also a bit large (5mm) but it'll do considering I don't have to spend any money for it. I'd like to replace it eventually but that's probably last on my list.
For my next two eyepieces I was thinking a 6.7mm and a 16mm ES82 ... but then I realized they don't make a 16mm ES82 LOL. The 18mm ES82 is a 2" eyepiece and therefor too big, and I feel like the 14mm ES82 with a 2x barlow would be too close to the 6.7mm without the barlow.... So I'm not sure what to do there.
BTW I like the look of that Baader 2.25x barlow. Really nice and compact. Unfortunately I don't think i can justify another barlow... yet...

I have an 80mm F8 Vixen APO I use for travel. My ideal set up is a 17mm Vixen LVW and a Nalger Zoom 3-6mm. Not sure of your budget, but that is the best set up for me. Good luck in your search, you have a ton of great suggestions!

Just a suggestion: ES68* 24mm (1.25"), the ES68* 16mm, with your barlow. These are both nice eyepieces and both barlow well. Hopefully, they'll be availble sometime during the year...

csrlice12: People will not always want ES eyepieces. There's more to life than ES.
Oops, did I say ES? RANT OFF.

The FOV of the 24 would almost be the same as my 35, so it doesn't really make sense to get that one. The 16 ES68 with a 2x barlow would be the same FOV as the 6.7mm ES82 so that's a bit of a waste. the 20mm ES68 would probably by the "ideal" in terms of FOV both with and without barlow... but ... kinda feels like a letdown to be spending all that money and not get an 82 degree FOV...

Re: the 24mm It's not just the same FOV, It's also higher mag. The 6.7 is a great eyepiece, but it doesn't get as much use as I like, mostly due to weather; but when the weather's good, it throws up some fantastic views. I find I use the 8.8 more; but you have a diffent scope. The 6.7 would give you 83X and would probably work well in your scope. At f6.9, the 6.7mm would give you essentially a 1mm exit pupil--which is great. Anything below that and your image will start to dim, too much past that and it'll fall apart all together as the exit pupil would be too small.
