The Baader Zoom Barlow is 2.25x.

That means the 24-8mm range becomes a 10.7-3.6mm range.

The Barlow is a simple thread-on unit, and then you have a 3.6mm to 24mm range.

I'm just sayin'........

But then you have to fiddle with screwing the Barlow on and off.  I'd rather switch back and forth between a couple eyepieces than deal with screwing that little Barlow on and off in the dark.  

 

I do have two Baader Zooms.  I could take them both out and keep the Barlow on one of them.  But I don't like putting that Baader Zoom plus Baader Barlow at the end of a diagonal.  It is a cantilever.  I don't like cantilevers.   In fact, I only use the Baader Zoom + Baader Barlow in 2" format.  Then I put a 2" extension over the little Barlow.  The whole end below the shoulder fits into a Dob focuser.  Still not so good for telescopes that use a diagonal.

 

Besides, the Baader + Baader Zoom only goes down to 3.6mm, not 3mm like the Nagler Zoom.  

 

I think I'll stick with the Baader 8-24 Zoom and Nagler 3-6 Zoom.  I suppose I could bring along the 7 DeLite to help bridge the gap between 8 and 6.

Hmmm...

I use a 3x Barlow, which gives me a continuous 24mm-2.7mm.

 

If you want to go your route, and bridge the gap between 8mm and 6mm, you need more than just a 7mm. How about a Morpheus 6.5mm, along with a Kasai 7.5mm, which is still being sold. All three together would make a great gap bridge. wink.gif

With most any Barlow on an eyepiece that goes into a diagonal, you tend to create the cantilever effect.  I like to avoid that.

 

Oh, I have other eyepieces to more thoroughly fill in that 6-to-8mm gap.  But then I would be upsetting my grab-n-go protocol.  IMO, bringing out a half-dozen or more eyepieces for grab-n-go can get a little silly.

A half dozen? You need to do your part to uphold the dignity and honor of the G&G community. Start with two dozen, and work your way up. ;)

I bought my first set of orthos eyepieces from UO when I was 14 in 1975. I went in person. Zeeb Road was in the country then. It's all developed now. I bought my set of Claves a few years later. Sold them off as they where duplicates. Last year I picked a 25 mm Ortho last year. Looking pickup a 12 and six.

 

I noticed that the Kohi Orthos went up in price.

 

Well, we still have the Brandons.

 

Where in Zeeb Rd was the shop?  I don't remember many businesses there in 1975,  PB's & UMI maybe.

I don't remember. I didn't drive, my mom did. I remember it being a small single room metal building. But it was a long time ago. I think the building was behind his house. It certainly was a small out building on his property. It would be easy to miss if you weren't looking for it.

Also,remember lots of this early stuff was before the Internet.....S&T advertising and ??? was the source of knowing about UO.

 

I learned about UO from a shop in Oakland/Berkeley, California where I bought my UO 11x70 binoculars in the 70s.

I used to pour over his brochures for hours dreaming of a ten inch newt I wanted to build but had no money (I was in my teens),

I think my first purchase from UO was an ortho eyepiece back in the early '70's.  The eyepiece is long gone now.  I included it when I sold my Edmund Palomar 4-1/4" f/10 Newt to a middle school science teacher in the early '80's.  The year I sold it, not the teacher.  :grin:

You can still get the same eyepieces marked with the Kokusai Kohki badge in place of UO at Agena... But the 25 mm & 4 mm units are out of stock at the moment...

http://agenaastro.co...epiece-set.html

Sad to see Jan Seyfried retiring... It won't be the same without him, though I've known this was coming for awhile now... I started buying eyepieces & other accessories from Jan back in the 1970's. Besides being a GREAT place to do business, he was a lot of fun just to talk to on the phone... LOTS of knowledge going way back...

Another one I really miss is Kenneth Novak... I still have his parts on some of my telescopes... Like Jan, always good stuff...

Very sorry to hear this but everyone deserves a bit of retirement. UO has served the amateur astronomy community very well over the years... yet another reason to treasure my UO VTs.

I have a complete set of UO VTs. You can have them when you can pry them from my cold dead hands.......

Just came across this news!  I echo all the other positive tributes to UO.  I have a number of their EP's and their Orthos hang in there with my Brandons and Delos while costing a fraction of their price. Can't help but feel a little bit of loss, although I wish the owners all the best.

Here's a photo of the University Optics eyepieces that the Astronomical Society of Harrisburg owns - a 55mm Plössl, a 40mm MK-70, a 45mm Plössl, a 32mm König, a 25mm MK-70, and a 1.25" 32mm König.

Truly sad to see them go.  Personally I love my UO VT orthos and very glad I bought them when I did.  I did have a set of the original Baader ones as well but sold them when people started paying silly money for them in the great ortho stampede a few years back.

Way back in 1969 I bought a set of their UO Professional Orthos (4, 6.8, 10.2, 28, plus the 16mm Koenig) and used them as my main eyepieces for 25 years. I loved their little leather cases. When I was working for Gary Hand I ended up selling them to him so I could buy a set of the then new Pentax XLs as I finally gave in to using my glasses for observing. Right now I have one UO eyepiece that I picked up last year, the UO 55mm Plossl. I have now owned the big three of that size, the TV 55 Plossl, the Meade 1st gen 56mm Super Plossl, and finally the UO 55mm Plossl. They were all very good. Still have the Pentax's after another 25 years.

I've shown these before, but I thought it might be appropriate for this thread.  I've tested everyone of these and they produce perfect Airy discs from edge to edge in my 6" f/8 APO.  Except for the 2" Konig, which needs at least f/10 for the same performance, but nevertheless is a fine wide field eyepiece.

I like mine, so glad I got them.  Two full sets no undercuts except for one 25mm, it has the undercut, not that I care but some hate those undercuts.  I use them all the time, absolutely love the volcano top design.
