On other Hyperions, I found that a ring spanner like this was a great help

Ebay UK Lens Ring Spanner


Nice tool; the old vice grip can also surely unscrew any stubborn nosepiece (just make sure several layers of protective cloth are wound around the sleeve before engaging the grip to prevent any marring).

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?

Regards


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:

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.......................


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.

Best,

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?

I just leave mine in 1.25" mode and use an adapter in the focuser, as I have 2" & 1.25" oculars. Simplifies things.

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.

First time I've heard of loose rubber twist-eyecup on the zoom, it might belong to some other unit as my 2 zooms' eyecups both have a snug fit. If it were mine, will get in touch with the vendor and have it replaced, just pluck it out of the zoom, it would be easy to mail.

Hernando,
Thanks for the reply and the pics- I believe I will stick with the TV 2X barlow for now. It looks like there is not much of a difference in length in the two when you compare the space between the focuser and the bottom of the zoom. There is however a huge difference in the length in the barlows on the end that fits in the focuser. Once again thanks!
Tim

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

A penumblar lunar eclipse was visible here tonight and I used the 8mm setting of the Hyperion zoom to take a shot of the eclipse at its peak,

Bill


Bill can you explain this more since I tried mine with a barlow and had the same problem (needed a slightly shorter barlow to enable my telescope to focus). Wasn't sure if I just needed a different barlow or something else.

If you look at my image, you can see that barlow sits lower, because I used a 1.25 adaptor that had a side cut for the locking screw. Most 1.25 adaptors sit higher and have the locking screw in the side. This seems to be a common problem when using this barlow at least when I'm using mine on my Lunt Solar wedge. I think the Locking ring adaptor in the previous post could help.

EDIT: A 2" adapter is not really necessary when going for the 2" format w/ the Baader 2.25x barlow, just use the zoom's 2" sleeve:

Using the Hyperion zoom in my refractor scopes posed no in-focus problems (more so on my SCT & Mak), like with the William Optics Megrez 102ED scope shown below:

Posted Image
Hyperion zoom on a WO Megrez 102ED refractor

Or with my Antares 6" refractor:

Posted Image
Hyperion zoom on the Antares 1529 152mm refractor

Or the Orion ST80:

Posted Image
Top: Orion ST80; Bottom: William Optics 66mm petzval

But the WO 66 ED refractor shown above (my RDS - Rapid Deployment Scope for quick looks & favorite for lunar photos w/the Hyperion zoom) was a bit finicky and wouldn't come to focus with the zoom using an OPT diagonal (which came with the scope when I purchased it used in immaculate condition in its WO soft-case and a WO 188 tripod all for $290). It required more in-focus racking.

The good thing was that the OPT 2" diagonal's EP-side lip can be unscrewed:

Posted Image
OPT 99% dielectric 2" diagonal lip (EP side w/Hyperion 21mm)

So I had a substiture aluminum low-profile lip custom machined to screw-in to the diagonal, replacing the original EP-lip, and that solved the problem by moving the light path closer to the EP; the Hyperion zoom now works glitch-free focusing on the WO66mm . There are also off-the-shelf low profile adapters available as have been discussed in other threads on here.

The WO66ED/BHzoom duo is my favorite afocal astrophotography gear for Moon shots.

My focusing problems might because I mainly use the barlow with my Lunt Solar wedge and it does extend the position of eyepieces.

Bill, have you tried the BH zoom/barlow in your Lunt Solar scope in the zoom's 2" configuration?

No, always use the 1.25 nose piece and the don't use the barlow often with the Lunt as the power is usually too much for Ha viewing, image is just too dim. I always use the barlow with the wedge, as white light viewing can take high power and still be bright and sharp.

Thanks, that's good to know. Visually, from the pics posted, it just seemed as if using the 2" sleeve of the zoom w/barlow will make it protrude less on the Herschel wedge, bring it closer to the light path, and possibly do away with the need to use a low-profile 2"-1.25" adapter.

I can't remember if I ever tried that, once the clouds leave and the Sun sees some more action, will try.
