Hello,
I just got a Celestron Nextar 127 SLT telescope, and I would like to know that eyepieces could be interesting for this telescope, I have a zoom eyepiece something old that does not offer good image quality.!
Greetings.

What eyepeices do you have already, and what is your budget?

You can spend $700 on a single eyepeice, but that is not usually necessary to do that.

You can put together a nice collection of 3 or 4 decent eyepeices for under $120.

But I don't even know if you have that much to spend.

There are many decent, low cost Plossls around that will give you quite excellent performnace.

They will not have the larger apparent field (the difference between looking though a narrow opening and a wide opening) of many expensive eyepeices, but they will get the job done very nicely.

I would recommend that you go with fewer, better quality eyepcies than more granular eyepeices. I personally beleive that you really only need maybe 3 eyepieces... Low, medium, and high powers.

I mean you only really need one to use the telescope, but three gives you enough flexibility for a lot of observing.

For your scope, perhaps something like a 32mm, 20mm, and 13mm Plossl would be enough for a lot of great observing.

But we really don't know much about what you have and what you are comfortable spending.

My advice would be to buy some used Plossls in these focal lenghts and try them, then once you have some experience, use these as a way to bettery develop your future requirments.

What do you like to look at?

If you have no ep's I suggest one in the range 25 to 35 for low power ,one around 15-17mm, and a 9-11mm, plus a 4-7mm TMB planetary .

Most of my views are with a 25 or 26 ,and 9 or 10,depending on which scope or lens kit ,with the 4 or 6 less often called for. How much power you want depends on your normal seeing conditions,the objects, and the scope quality.

By the way,I find the Celestron 8-24 zoom EP good enough for me as zooms go.Could probably do well with a 32mm plossl,the 8-24 zoom ,and a 2x shorty balow.

Focal length 1540mm.
Desirable magnifications: 40x, 80x, 120x
EP focal lengths: 39mm, 19mm, 13mm
Since the scope uses 1.25" eyepieces and there is no good reason to convert to 2" (the opening in the back of the scope is <1"), I would suggest:
32mm Plossl with a full-barrel diameter field stop: magnification 48X, field size 1.0 degree. Pretty good for a scope of this focal length and eyepiece size.

20mm Plossl. Magnification 77X, true field about 39'. Good for larger planetaries, many star clusters, most galaxies, all globulars, and Moon.

12mm Astrotech Paradigm or Orion Epic II ED or Telescope Service ED LER,
magnification 128X, approximate field size 28'. Pretty good for planets, Moon, small planetaries, small galaxies, double stars, globulars, small star clusters.

Later on, add a 2X barlow lens of quality for the occasional use at extremely high powers (I've had mine up to 328X under exceptional conditions of seeing). Normally, though, the above 3 should do it. My most-used eyepiece on this scope is a 16mm at 96X because I use it for a lot of lunar viewing and that magnification is seldom plagued by seeing conditions.

Do watch the diagonal's clear aperture. I've an Amici (correct image) prism that vignnettes anything longer, or of wider field than a 25mm Plossl.

I like to use 25mm, 18mm, and 10mm in my 127SLT.

My most used are 32mm 2" 70 degree for scanning, 20mm ES 70 degree and 15mm Paradigm for general use. For high power I use an 11mm TV Plossl, 9mm Expanse and for those very good seeing conditions a 8mm Hyperion. I also have a barlow if i want to go higher on the moon.

Get yourself an Orion 24mm Stratus, I think you had a post last week about focal reducers with this scope, sorry I did not have time to respond. This leads me to believe you may be looking for the widest possible view with nice eye relief without black outs.

I have tried many EPs with mine and I use this one the most, I call it a poor mans Tel Vue Pan. It will give you plenty of magnification and the widest fov.

Tele Vue Plossls is real good and I have it for 30 years! ES 68 or 82 degrees is also good, too!
