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.

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

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.
Don't know if that will solve your problem, but that's what worked for me..................Jim Jeffries

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.

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.

---

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. 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.

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?

Hi, twist-eyecup too loose? In what way? Below are the twist-ups on both the Mark III (right) and the previous Hyperion zoom (left) version with helical eyecups fully extended. How different is the one on yours compared to these two which are both buttery smooth when going up or down?

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.
Tim

---

Tim, yes, you can say that the Baader 2.25x barlow is a better fit, with a shorter overall profile compared to using the TV 1.25" 2x barlow as shown in the pics below:


Top - BH zoom w/ Baader 2.25x barlow screwed-on to the zoom's filter thread; Bottom - BH zoom w/Televue 1.25" 2x barlow

For scaling perspective and size comparison, below is a side-by-side of the Baader 2.25x barlow and Televue's 1.25" 3x barlow:

Actually, there is a set of instructions on the AlpineAstro site. Here's a direct link.

---

Thing is, that pdf link doesn't show how to convert the zoom from 2" to 1-1/4" or vice versa, or what to watch out for in doing the conversion. Like showing the connector & knurled ring in a simple exploded view as suggested by Jim should do the trick.

I have the mark III.
My twist eyecup is loose enough,in a way that i cannot keep it in place,whenever i gently place my eye on it.I think the twist-eyecup-ring is a little bigger than supposed...I am using for several months the other rubber eyecup so i am used to it ,but thought asking if anyone has dealt with a similar problem.As i said you cant practically observe with this twist eyecup.

With the 2.25 Barlow attached can the zoom be set to fit in both 1.25 and 2 inch focusers without any other change?

---

You'll have to use a 2" adapter; mine's the Antares twist-lock adapter which works very well, no setscrews to fiddle with.

I just use mine in 1.25, but it's hard to reach focus, that's why I have a recessed adapt., with a standard 1.25 adapt. can't reach focus. this is a problem on my little 3" refractor, which needs much higher magnification.

For those of you with the 2.25x barlow, I'm curious about the focusing issue (i sent this not to Bill, but now am asking others). I have the 8-24 mark 3 that I've used almost exclusively on my 12" dob, but earlier this year I moved to china for a couple years and didn't want to bring the dob, so I bought a 3" table top refractor (cheap, but easy to use for planets, doubles, moon, sun). It has a very short focal length (350 mm), so with the zoom at 8 mm, I still only get 43x power. I bought an OWL 3x barlow for it, but when I add the two, I can't focus (I need the combination to sit a little deeper in the focuser, it is just out of reach, which is why I asked the question about the recessed adapter).

So this is why I'm curious. One option is I can buy the 2.25 Baader zoom and see if that solves my problem (and then I have a usable zoom when I go home for my dob or an upgraded refractor), but I would hate to do that and find out that I have the same problem. My other option is just to buy a "cheap" 3.2mm ortho for the scope.

So for those of you using the baader barlow, are you having issues with focusing in certain scopes?

---

Hi,

If you haven't already tried it, see if this will work. Your Owl 3x barlow has a barlow element at its bottom that can be unscrewed, just like in the pic below:


Barlow elements unscrewed: Top - GSO type 2" 2x barlow; Bottom - Celestron EP kit/Omni 1-1/4" 2x barlow

Remove the barlow element & screw it unto the 1-1/4" filter thread of the BH zoom. The effective power in that case would be around 1.8x instead of 3x. See if it will focus in your 3" refractor.

With regards to the Baader 2.25x barlow, I tried it with my 2.5" refractor (388mm focal length) upon reading your post. Using a standard 2" OPT diagonal with no modifications, the scope will not focus with the BH zoom (required just a little bit more in-focus racking to be able to focus). Same thing when I used a TV 3x barlow with the zoom (required even more in-focus racking than the zoom alone). But when I screwed on the Baader 2.25x barlow onto the zoom, the scope came into focus.

Hope this helps.

Best,
