[Re: jrbarnett]       #5494191 - 10/29/12 08:02 AM Edit   Reply   Quote Quick Reply   Dear Jim, A most interesting shootout. I have obtained similar results comparing an 80mm f/11 achromat to a high quality 76mm f/6.3 ED 'scope. I doubt elevation has very much to do with your results, but of course, it's always good to test that. Been doing some work on my own 60mm f/16.7 Skylight-Carton lately. Details here; http://neilenglish.net/further-studies-on-reverend-dawes-... Regards, Neil.

From what you found it seems either one would need to be set a bit firm to carry a heavy load, like a binoviewer. Also, the design of the Astro Tech R&P looks different from the ones I'm used to seeing. Ed D Post Extras:       Wes James Postmaster Reged: 04/12/06 Re: Astro-Tech 60mm f/7 ED triplet, first report.

On the plus side of the ledger at least it isn't pink.

[Re: moynihan]       #5563484 - 12/10/12 02:04 AM Edit   Reply   Quote Quick Reply   I really like my AT72, yet haven't really used it for astro-visual as of yet (only asto-imaging). I have hooked up various combinations for imaging to test the train, yet this was under day light conditions on a distant tree. Perhaps someday I'll spend some eye piece time with it. P.S. did use it with a solar filter to check out SOL a couple times. Post Extras:       Mr Onions Two Time International Photographical Competition Winner Reged: 04/14/07 Loc: Newcastle upon Tyne.

My TV60 will be coming sometime at the start of the year,I'm sure it will go up against my Skylight { If the breeze round here ever dies down and that's not a given in the north east of England } I walked two miles last night with my 80mm to observe Jupiter in honour of the great Patrick Moore,I only managed about 20 seconds through a 32mm plossl,I just bring that as a finder. When is your LOMO due? Post Extras:       jrbarnett Eyepiece Hooligan Reged: 02/28/06 Loc: Petaluma, CA Re: Astro-Tech 60mm f/7 ED triplet, (w/ Pics now!!!). [Re: dscarpa]       #5563926 - 12/10/12 10:50 AM Edit   Reply   Quote Quick Reply   My AT72ED, too, is pretty middlin' in the optical quality department. FYI. The AT60EDT requires a surprisingly long time (for a 60mm) to cool down. Image quality improves somewhat after about an hour (assuming a 20F temperature delta to be overcome), but even so, it's not in the same league as the AT111EDT I also have. - Jim Post Extras:       Pages: 1 | 2 | 3 | (show all) Previous   Index   Next   Threaded   Extra information 40 registered and 42 anonymous users are browsing this forum.
