The above article explains a lot.
You don't say which Celestron 130 package you have. So I can't tell what kind of Celestron eyepieces came with the package.
If the included eyepieces, are Celestron Plossl eyepieces, those are pretty good. Not as wide as the AT Paradigm or the Celestron X Cel LX, but petty good. If they are Kellners, then they will work but provide a fairly narrow FOV. I would replace them with a 24/25 mm Paradigm or X Cel as time and budget allows.
I often recommend a 32 mm Plossl for low power wide view but some small low focal ratio scopes will show a shadow of the secondary mirror with a 32 mm Plossl. I don't know yours so I can't say. But the 25 mm, if it is a Plossl, or one of the 60 degree eyepieces can serve that purpose. A 25 mm Paradigm would provide about a 2.3 degree FOV for star hopping, sky scanning and viewing wide DSOs.
The TV Plossl is an excellent Plossl, better than the Celestron but still around 50 degrees AFOV. (see the article for AFOV)
Assuming a limited budget, I suggest you build out your AT Paradigm or the Celestron X Cel LX eyepiece set. Wherever you see a need, go to one of these series first.
AT Paradigm line 60 degree AFOV.
Discussion about Paradigm eyepieces
If the budget is higher, consider one of these.
Explore Scientific 68 degree and 82 degree line. I have the ES82 14, 8.8, 6.7 and 4.7. The ES 68 24 is a very popular low power wide view eyepiece. Many reports compare these favorably with the premium eyepieces.
Eyepiece Designs - This is the one I turn to when I am trying to understand or explain the differences between the various designs. There are many different designs, Many are named for their original designer, such as Huyghens, Ramsden, Kellner, Plossl, Konig, Erfle, Branden and Nagler.
