Thousand Oaks Type 2 filter

Posted By Paul Gustafson

Get the Baader film instead. I've owned both, and the Baader was noticeably better than the TO in every way. There was always detail visible in the Baader that was not seen in the TO. The regular window glass TO uses limits its performance.

New AstroGear at Stellafane

Posted By Paul Gustafson

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.

Binoviewer edge performance?

Posted By Paul Gustafson

I have both those eyepieces and find no deterioration in edge performance when used in the AP/Baader/Zeiss binoviewer.

Not sure about the design specifics of your binoviewer, but it's possible that the corrector is needed. In the AP the 1.25x corrector is designed to eliminate slight chromatic aberration introduced by the prisms. In a slow scope, I see little difference with or without the corrector, but in fast scopes it makes a more noticeable difference.

favorite bv eyepieces?...

Posted By Paul Gustafson

If one can find (and afford) them, the limited edition Zeiss Abbe orthos are the best binoviewing eyepieces available. They are my primary bv observing eyepieces. However, the short eye relief on the 6mm and the 4mm make them a bit uncomfortable to use. For wide field bv observing, I use 22 Panoptics (soon to be replaced with the new 24 Panoptics), 16 Naglers t5, 13 Naglers t6, 9 Naglers t6, 7 Naglers t6, Radians 5 and 3. I will probably add the 19 pans and replace the 5 Radians with the 5 Naglers.

As Dave Barry said, "There is a fine dividing line between 'hobby' and 'mental illness.'"

19mm or 22mm panoptic

Posted By Paul Gustafson

The 22 has a bit more "wow" factor, but the 19 is physically smaller. Other than that, it's a toss-up.

Laughable telescope ads?

Posted By Paul Gustafson

Not sure about the copy, but the Meade girl in this ad appears to be offering something more than telescopes:

Tele Vue Day at Highpoint Scientific

Posted By Paul Gustafson

>>I also had the opportunity to compare an interesting (and surprising) new Tele Vue prototype to a Thousands Oaks version of the same through Dave's telescope.<<

A new prototype what, if I might ask?

Dilated pupils?

Posted By Paul Gustafson

Next time you have your pupils dilated at the doctor's office, notice how horrible your visual acuity becomes.

Buy New 24mm Panoptic?

Posted By Paul Gustafson

Nice size, quite a bit smaller than the 22 Pan.
