    Default Zoom Lens options



    I'm looking at acquiring a zoom ep. I've a Celestron Nexstar 6SE. Thinking of 3 options. Either the Celestron 8-24 wide angle unit (GBP79), the Celestron De Lux 8-24 (GBP217) or the Baader Hyperion 8-24.(GBP189). The attraction of the 2 expensive units would appear to be an increased FOV only.
    The standard Celestron has a major price advantage, will I notice a corresponding difference in quality?

    They are all decent eyepieces and get good reviews, the difference in FOV is slight between the 3 so I would get what is acceptable for your budget and fits your needs. The Baader is more expensive because of the options that it provides you with all the different adapters available.

    The Baader is MUCH wider at the short end, around 72º. It's also larger and heavier.

    Another one to consider is the Orion 7.2-21.5mm (or the Lunt version, which is the same). I have the Orion and it's remarkably sharp.

    I'm using the Baader and find it does a great job pulling in objects I'm viewing. It has good contrast, it's sharp to my eyes, and very smooth operation. It is heavy but it's a very solid build.

    First off I will say I am not a fan of zoom eyepieces. I do get that they offer nice utility for someone who wants to streamline and even for those on a budget that want to get a wider range of focal lengths for their dollar. That is why many like the Zhumell zoom.

    Zhumell 1.25 Inch 8-24mm Zoom Telescope Eyepiece - Telescopes at Telescopes

    I used to own the Hyperion Mk-III, but I simply didn't care for the restrictive AFOV, particular in the longer focal lengths of its range. In my faster dobs (f/4.5 and f/5) I found its performance good, but not great - same as the single f/l Hyperions. I eventually sold the zoom and other Hyperions I had and moved on to the ES 82 line which was clearly a better performing eyepiece. Personally I prefer single f/l eyepieces and I don't find swapping out EPs an issue.

    But of course those are my personal preferences based on my own experience. We each have to find what works for us within our budget and tolerances.

    I prefer the single focal length eyepieces myself. I do have 1 variable though, after owning a vixen 8-24mm it was replaced with a Televue 3-6mm (constant 50* FOV) and then that was eventually replaced by the Antares 5-8mm (constant 80* FOV)

    True I never had a chance to use a premium zoom, like televue. With budget zoom in particular on planets I get feeling that they just increase the object size without adding any additional details.
