I have some of the Starguider Dual ED eyepieces and I am thinking about completing the set, but the Celestron X-Cel LX eyepieces have similar specifications and are only slightly more expensive.

Has anyone compared the two under the stars?

Which one(s) are you needing?

I've had both (not at the same time) in shorter focal lengths and preferred the 2ED.

I am thinking about the 25mm and the 15mm. But the Celestron X-Cel LX eyepieces look better made.

Ah. Others will have to weigh in in those, my experience is with the <10mm ones.

I have the 15, 12, 8 and 5mm Starguiders, plus the 18, 9 and 7mm Xcel-LXs.
I find all are very good optically.
Minor differences are that the Xcel-LXs seem better made, but their twist-up eyeguard gets very stiff when it gets cold.
I recommend both - they give very good value for money- go with the ones you can get cheapest.
You will not be disappointed :).

In general these seem to be considered almost equal in performance, out of 10 people 5 will like one and 5 the other.

Pick them on price then it is the Starguiders, or if you want a slightly better selection at the smaller focal lengths then get the X-Cels.

Any experiences with the 25mm Starguider or X-Cel LX?

I had the 25mm Paradigm (same as the Starguider). I thought it was a good value -- quite nice in my refractors, sharp to the edge @ f6.9. Gave it to my brother as part of a kit I put together for him.

I have the 25, 18 & 12mm LX's and the 2x LX Barlow and all perform excellent in my 6" & 8" Dobs and my 102 & 120mm ST refractors. They are well constructed and provide great views, the twist up eye cup is a nice feature. They are a great compliment to my three 2" wide field EP's.

How does the 25mm Starguider or X-Cel LX perform at f/5?

Maybe I am missing something but don't you think you should tell us what scope(s) you are using and what are your viewing interests ? Then maybe we could be of real help to you .

I know there are inexpensive eyepieces that perform fine around f/10 but not well at f/5. I need to know how these eyepieces perform when using a "fast" refractor or Newtonian.

I use my XCel-LXs and Starguiders in my f6 refractor.
They work just fine.

I wouldn't call the XCel's inexpensive, just practical for the average scope / viewer ! They work great in my f 5 & f 6.5 refractors and f 6 & f 8 Dobs as I mentioned.

Just updating this here.

I tried a 25mm Celestron X-Cel LX last Saturday in my fast 10" F/4.7 reflector and it was excellent for the price!

Other eyepieces do not fare so well in my brutal bench test of a scope! I do not use a coma corrector and the 25mm Celestron X-Cel LX was sharp out to 85% of the field.

If you're on a budget, the 25mm is excellent.

I can vouch for the Starguiders as being very good eyepieces for the money. I use a set of 18mm for binoviewing, a single 12mm and they work very well for solar also. I have used them on a f/5, f/6 and f/7.5 refractor with good performance on each. They are also very comfortable to use. Mind you, I only use them for solar, lunar, planetary. I have no experience with Celestrons offering though.

I have not seen a better eyepiece line at the price or near the price of the Celestron X-Cel LX's.

I have the 12mm, 9mm, and a new 7mm.

In terms of design (love the twist up eyecup), quality of images in all my scopes large and small, Celestron hit a homerun with these.

I was able to resolve some very faint detail this past Saturday night on a galaxy for an upcoming GL video using the 7mm in the 12.5" f/4.8 dob. It fits very well between my 8mm and 6mm Delos.

Plus they are very comfortable to view through with nice E.R.

I would state in 47 years of observing (mostly deep sky at the edge) for the money they are the best I've seen.

The ED's are very good, also sold by Orion for $100 and AT for $60. I have the 5mm and it a solid EP.

The X-Cel are also very good and also sold by Meade. Just depends on the comfort level of your eye, but can't go wrong at this price point!

I personally think they're doing quite fine at f/5 (except in an f/5 Newt without coma corrector, but through no fault of the eyepiece itself). Well, except perhaps the last 5° or so, but that's picking nits.

I am looking at the Starguider 18mm for my Mark V binoviewer and solar scope.  My 17.3mm Delos don't work because they require too much in focus.  Does anyone know if the 18mm SG requires lots of in focus. 

 

Thanks, Kent

I have a 25mm X-Cel LX that I use in my f/4 reflector.  It's not as sharp as I'd like edge to edge as I would like.  But, most other eyepieces over 20mm with more than 52 degrees AFOV aren't much better.  Maybe it's just my scope?  I'm gonna try a 20mm Expanse clone with a 66 degree AFOV next.  That should give me a wider TFOV than a 25mm Plossl with 52 degrees AFOV.

Bad choice, Paul.

 

What you seek does not exist for your F/4 without spending the Bucks.

 

But, I'm sure you are having fun:-)
