    Default Celestron 93230 8 to 24mm 1.25 Zoom Eyepiece



    I have never used a zoom eyepiece before but am considering ordering the Celestron 93230 8 to 24mm 1.25 Zoom Eyepiece for convenience. I have decent Plossl eyepiece already so am not gaining any different magnification. As mentioned would be for the convenience of not having to transport a case of eyepieces around.

    Opinions are they any good or am I better off just bringing the case of a few EPs.

    Zooms are one of those eyepieces that you either like or not.
    I have had them in the past and they do add a bit of convenience but I prefer fixed focal lengths.

    I would much rather bring a small case of GOOD EPs. I say invest your money in a quality dedicated EP.

    This is the only reason to consider a zoom EP. However, zoom EP will be always inferior to fixed FL EPs in the same price range in image quality (contrast, transmittance, light scatter). As a result you will see less with less details.

    At one point I got Vixen 8-24mm Zoom EP assuming that at $219 price it should be at least as good as $50-100 fixed FL EPs. Not even close! I compared it side by side with Celestron X-Cel LX set, and Celestron EPs were noticeably better in contrast and transmittance, and had wider FOV. And for the price of Vixen zoom I can get three X-Cel LX Eps.

    I'm not a big fan of zoom eyepieces, but there are a couple of reasonably-priced 8-24's around. I like the Zhummel and Meade models. The Celestron model is short of them in the quality department in my experience.

    A few years back, I actually bought one of each for a side-by-side-by-side test with an f/9 refractor. (I'm naturally curious.)

    I find my Williams 7.5-22.5 zoom is great for public nights, so I don't have to change eyepieces too much. The quality of this one is quite good, and it holds its own with the basic plossls etc. One thing that a lot of people don't realise though is that the apparent fov actually gets smaller in a zoom as you go to the lower power, which is the reverse of what you want if you are looking for a wide-field low power experience.

    The other zoom that I use is the TV 3-6mm. This is magic for getting just the right high power for the conditions, and is excellent quality: but if you get one new (I didn't!) it is very expensive...

    Hi Normy,
    I had the same eyepiece you mention, and I'm with Gabby; you either like them or not. I found it "OK", but like a few others, I'm more happy with a fixed size lens. Just preference, I guess. Though the guy I sold this lens to was very happy to get it; his went missing and for the $50 I gave it to him for, he was thrilled.
    If you could try before you buy, that would be the way to go.
    Best of luck,
    Mark

    I have 3 zooms. An ancient UO, Vixen LV, and and Baader Mk IV click stop 8-24mm. Each has its role as far as convenience is concerned but zooms make optical compromises that are not favorable. I'll travel with fixed focal lengths as a first option.

    I have a traveling case to cut down on baggage. The eyepieces are in storage cases. Before traveling I'll transfer a selection to the traveling case.

    I too agree with Gabby. Zooms were fine in my early days in this hobby. At the time my Celestron 8-24mm zoom came as a package deal with my XLT120. However I eventually got the Meade 8-24mm zoom which I found to be noticeably better than the Celestron zoom. As I became more experienced I moved on to good separates. I rarely ever use a zoom anymore and when I do it's the Meade zoom I use. The Celestron zoom is currently lost in a "sock drawer" somewhere
