New AstroGear at Stellafane

While attending the 67th annual Stellafane Convention last weekend I had the opportunity to use three new pieces of astronomical gear, two of which have not yet been officially unveiled.

On Friday I had some spellbinding views of solar prominences and filaments through a new Tele Vue refractor, the TV-102i. This instrument is a binoviewer equipped TV-102. It has a shorter tube and a new barlow system to allow low power binoviewing. Extension tubes allow use without the binoviewer.

On Saturday night I had the pleasure to observe a number of objects through a new Tele Vue ocular (actually a pair of them), the 24mm Panoptic. The 24mm is much smaller than the old 22mm Panoptic and is eminently suited to binoviewer use. The views of the Double Cluster, Stock 2, Comet Hoenig, and other celestial objects were excellent indeed. Just as with a Tele Vue Bizarro a few years ago at Stellafane M27 appeared to float above the background starfield in a classic example of the binoviewer induced pseudo-3D effect.

A bit later I ran into Phil Harrington and was transported onto a delightful cosmic tour via a 15x60 Zeiss Classic binocular. I was very impressed with how the comet and a host of deep-sky objects, M31 in particular, looked through these expensive armored glasses.

A 24mm Panoptic?? COOL! How was the eye relief on that one, especially as compared to the 19mm Panoptic? This could replace my pair of 19mm Pans and the 27mm Pan...Any idea of price?

Dave,

Thanks for the report.

Phil noted in his latest Starware that the Zeiss 15x60's had better optics than the Fujinon 16x70's. I've owned both and agree. I tried the Zeiss 15x60's just before Zeiss took them off the US market a couple of years ago and I bought them immediately. Extensive side-by-sides with my beloved Fujinon 16x70's resulted in the sale of the Fujinons.

A couple of things to consider. Zeiss has since reintroduced the 15x60's to the US market. The Zeiss and the Zeiss Jena are two _very_ different animals, the Zeiss being the better optical instrument by far. The latest iteration, the Zeiss 15x60 B/GA T*, is the one to get, in part due to its better eye relief over previous versions. It's pretty impressive that they could put optics like that into a body about 7 inches long, 8 inches wide -- hand holdable for me, unlike the monster Fujinon 16x70's. Its center focus is a plus for birding and marine use, too, although close focus isn't its strong point.

I can't wait for the 24 Pans. Sounds like a great replacement for my 22 Pans in the binoviewer.
