I've always used the eyepiece with the 2-inch nosepiece. Last night I wanted to use a filter to look at Jupiter. I could not get the 1-1/4 nosepiece to attach to the main eyepiece body. There is an adapter with a knurled outer that it will screw into, but otherwise there is nowhere to attach.

Is it me or the eyepiece that is missing something?

I'm not totally certain about this, having only played with one at NEAF a few years ago, but if I'm not mistaken, you must first unscrew the 2" nosepiece and you'll then be able to convert it to 1.25" Take a look here and click on the small image showing the zoom with all the various attachments.

You know.........I thought I was going to be able to help on this one, as I just got a new one about a week ago. I took mine apart and set it up for 2", because that was how I planned to use it. For the life of me, I can't figure out how to get it back to 1.25"!!!
There are a total of (3) pieces involved, that much I know, as mine is brand new..........1.25" nose-piece, 2" nose-piece, and the flat knurled ring(???) Guess I'll have to follow this thread as well :thinking: :foreheadslap: :thinking:

LATE EDITION: After looking things over a bit more, there IS a rubber washer/grommet that is about the same size as a lens cap, with a hole in the center............that may(??) play a part, but I'm too busy with company to check it out.

Here's an illustrated guide on how to convert the Baader Hyperion Mark III zoom from 2" to 1-1/4" (works with the older Hyperion zoom as well).

The Mark III zoom in 2" mode:

Posted Image

Start by Unscrewing both the 2" sleeve & connector ring:

Posted Image

The tricky part is when only the 2" sleeve is unscrewed but not the connector ring - both of them must be unscrewed (not necessarily together) to convert to 1-1/4". Shown below is how the 2 look like when separated (set both of them aside for this operation):

Posted Image

Next, find the knurled ring and the 1-1/4" sleeve shown below which you must have put away somewhere when converting from 1-1/4" to 2"

Posted Image

Screw on the knurled ring as shown below:

Posted Image

Finally, screw on the 1-1/4" sleeve onto the knurled ring thread and you're done.

Hope this helps.

The tricky connector ring. It seemed to belong there and I didn't want to push too hard. :) I'll give it another try when I get home. Thanks!

"Thank You"!..........I'll have to go try that out myself. I doubt I'll ever use it in 1.25" mode, but at least I'll know how :)

You're welcome. Yes, sometimes things don't seem what it is with this zoom because of its seamless modular design, like some owners miss out that the zoom has a helical twist-up eyecup that seemingly does not exist.

Jim, you're most welcome, yeah knowing how to convert might come in handy someday. About the rubber washer/grommet that you mentioned earlier which comes with the Mark III, it's used when going binoviewing with two zooms. The top eye segment of the zoom can be unscrewed (again, seemingly not an option but it's possible) and the grommet replaces it and becomes a fold-up eyecup instead of the default helical twist-up. In doing so, the diameter of the zoom's top is reduced yielding more nose room when binoviewing. Can't be done on the old/previous zoom version.

Best,

Thanks!!..........that is also good to know. It's also nice when someone knowledgeable on here is willing to help, and not be a snob.

Don't feel bad,you are not alone , after attaching the Hyperion barlow, I couldn't get it back together or figure out how I could use the 2" nosepiece again. I was finally able to use both nose pieces, but it can be a mystery of attaching different adaptors. Wait till you try their barlow. :crazy:

Lol :grin: Thanks Bill; I have a lot of barlows - TV 2x, 3x, Powermate, GSO, Antares, Celestron, etc., but because of its small compact profile, I've gravitated more and more towards using the Baader 2.25x barlow that you've mentioned and shown in your pic above.

Hernanado, Thanks for the great pics and making it clear.

Here's my problem. I bought a Mark III used. It came in 1.25" mode the with various adapters. Mint condition.

It was not until several months later that I thought about changing to 2" mode. Yikes! The "knurled" ring is on so tight I can't budge it. Ditto for the 1.25" nose piece. I tried as much twisting force as I dared (hard to get a grip) and then gave up.

Anyone else had this problem?

YES!! -- Initially...........when I first took my new one apart, it was tight as a tick!! I finally figured out that the 1.25 nose-piece must be removed first, then the knurled ring. Can't do both at once.

Exactly as Jim said, start by unscrewing the 1-1/4" nosepiece first. Don't worry about anything/lens falling out when you do that, nothing will, it's just a metal sleeve. After that, do the same with the knurled ring. Having tried twisting the knurled ring first might have locked the 1-1/4" nosepiece, so try a tightening motion on it before unscrewing it. Let us know how it works out.

Jim and Hernando,

Thank you both. I will concentrate all efforts on the removing the 1.25 nose first. It's on there tight! Now that I know the proper order, I'll go at it with more confidence.

Alright, try some tightening action on the knurled ring too to make it inch up a bit back to its old position, so as to allow the 1-1/4" nosepiece some leeway.

Best,

I'm sure it must seem redundant to those that are experienced, but it WOULD be nice if manufacturers would put in even a simple "exploded drawing", so that a guy could see how some of this works.......................

Hernando, funny how few people now about this barlow. I found out from you and like you mentioned, it's small size and performance is hard to beat. It's another reason I love my Hyperion zoom.

Usefull information!Thanks!
BTW i am the only one that has a twist-eyecup too-loose-problem that you can't practically observe with it,but i have to use the rubber eyecup that came with it?

Agree, a simple instruction sheet with an exploded view would be helpful and hope that Baader is listening here.

That's right Bill, the Baader 2.25x barlow seems to be a well kept secret. :) Well, they're missing out on a good barlow option - it's sharp, compact, versatile, easy to use, and as you've said too, performance is hard to beat. Just a conjecture here - the usual notion of a barlow is that it's big with a hallow cavity to insert the EP snout into, but that's not the case with this small-profile barlow so just maybe, some might be thinking - nah, that's not a "proper" barlow. :foreheadslap: Furthermore, many are not aware that the barlow can actually be used not only with the zoom but with regular 1-1/4" EP's too by simply screwing it onto the EP's filter thread. Wait 'till they get to actually try one out.

Best,

Hernando,
I own a TV 1.25 2X Barlow that I use with my Hyperion Zoom. Would the Baader 2.25X barlow be a better fit? It looks like they stick out from the focuser just about the same.
