    Default Baader to Zoom or Not?



    Help me out guys, I cannot decide what to buy.

    Option A. Baader Hyperion 8-24 zoom.

    Option B. Buy 17mm and 13mm individual Hyperions. With the optional fine tuning rings, this would give ten different focal lengths from 4.3mm up to 17mm.

    My Skywatcher dob is an f5.9 which supports both 1.25" and 2.0" barrels. My interest in purely visual at this stage (although I note that attaching cameras is well catered for with these eyepieces). I have a broad interest in viewing all that is available. My normal sequence is moon, followed by any available planets, then a quick run round some favourites (M42, M35,36,37) before settling in to the evenings project.

    Option A. Is a bit cheaper. I would lose out on the 4 to 7mm zone, which does include the recognised "maximum" magnification of 200 for my scope. I've read that the unit is pretty much parfocal and obviously negates the need for a lot of eyepiece swapping.

    Option B. I would lose out on the 18-24mm zone, but I do have a 25mm super plossl and also a 2" 32mm eyepiece when I'm in the mood for the Hyades, Pleiades, M42 etc. I've read good things about the versatility of these eyepieces but have been warned that swapping fine tuning rings around in the dark, probably with cold hands is a definate no-no !!

    So, thats what I've learned from reading. I understand that the zoom has the same AFOV of 68 degrees that the individuals have, except it does reduce at the 24mm extreme back to 52 (I think).

    I've tried to outline the pros and cons as I see it. The bottom line is I will chose the option that is best optically.

    I'm really hoping you guys have some opinions on this to help me decide.

    I can not answer your specific question BUT do you think you will enjoy or even consider sitting on your observation chaih in the middle of the night in cold weather swapping out the tuning rings etc on an eyepiece ????

    If you are like me I would not like to do that even on a nice night in the middle of the summer... My "guess" is that I'd loose a part pretty darn soon...

    Personally I'd get both the 13 and 17 but never mess with the tuning rings... I say this because while I understand the Baader Zoom is excellent, I just am not a fan of zooms

    BUT I do use a CHEAP Celestron 8-24 zoom with my 4 inch refractor at outreach events where there are always a lot of young kids who seem to be drawn to touching the glass of the eyepiece to see if they can feel the Moon etc....

    personally alec.i would go for the 8-24mm.
    you can also drop it in a barlow,so you will still get your 4mm!!
    just my opinion buddy.

    Thanks for your comments Bob and Andy,

    I also have a cheap zoom. Its unbranded, but I'm pretty sure its a Skywatcher. To be honest, I feared it wasn't going to be great. In reality, it was even worse!
    A lot of chromatic abberation making only the central part of the lens usable.

    What it did teach me though is that I LIKE zooms. Having wasted a little bit of money on this one, I didn't want to make another mistake in getting the Baader zoom. So, if the individuals are noticably better than the zoom, I will go for them.

    Andy - have you had the opportunity to use either of these Baader products?

    Clear skies to you both.

    Alec.

    Hi Alec,

    I have the Baader 8-24 Zoom and like it a lot - it is my number one grab-and-go eyepiece. For casual observing I am not bothered by the field of view (from a guy who has many wide field EP options), and the Zoom is every bit as sharp as the regular Hyperion EPs. Given the choice, there is absolutely no way I would sit in the dark, particularly at a remote site, and juggle fine tuning rings. Not sure I would even care to do this in a home observatory...

    Hello Alec,

    I have been using the full line of the Baader Hyperions, including their 8-24mm zoom. They have been replaced with EPs showing more contrast, brightness, and sharpness, after a short time. (I am still keeping their 2" aspherical.)
    According to my experience, the 8-24 zoom is maybe nice to enjoy zooming, but whenever it is about the zooms, a better choice is to have a short zoom EP, like mine TeleVue Nagler 3-6mm zoom, great for the globular clusters and planets. Otherwise, the Explore Sci EPs at fixed focus lengths seem to be the best choice regarding the performance/price ratio. Look also at Astro-Professional, they have a French page, and they offer some excellent 82deg EPs, like my working horse, the 16mm/1.25" one.

    Of course, hardly anything can beat the quality of the spotting scope EPs from Leica and Swarovski. But a convertor ring to 1.25" is required.

    Best
