Mars 5/2/2003

Posted By Dave Mitsky
Angel,

Offhand, I don't know what the CM was at the time of your image but I saw something similar to it on Tuesday morning, 4/29, through the ASH 17" f/15 classical Cassegrain at magnifications up to 381x. The use of a magenta color filter highlighted things nicely. This was the first good view of Mars that I've had this apparition.

Tall, narrow star map idea

Posted By Dave Mitsky
The Bright Star Atlas 2000.0 is quite handy in this regard because of its "vertical" layout.

Zambuto Mirrors?

Posted By Dave Mitsky
Every Zambuto mirror that I've ever experienced, probably several dozen by now, has been superb. (Some of my very best planetary views have been through Starmasters.) IIRC, part of reason that a Zambuto mirror performs so well is the remarkable smoothness of its surface.

Panoptic/Nagler Question

Posted By Dave Mitsky
Mike,

You didn't mention whether your telescope had a drive. If it does I suggest that you follow the latter course of action. If it doesn't have a drive you may just want to consider a type 6 Nagler or two as well.

Best 10mm EP for Deep Sky Observing?

Posted By Dave Mitsky
Jake,

IMO, you're being overly concerned about light throughput. The 9mm Nagler type 6, although outside of your price range, is a fantastic deep-sky AND planetary ocular. I routinely use my 9mm with my 101mm Tele Vue refractor and two 80mm achromats.

I've used a 10mm Speers-Waler on a couple of occasions. Aside from its length and issues with coming to focus in some telescopes it performs rather well.

The 10mm Pentax is very good and is probably your best overall option.

Sagitarius RULES

Posted By Dave Mitsky
Leif,

M22 is both bigger (29.0 vs 16.6') and brighter (5.8 vs. 5.1) han M13. Atmospheric extinction takes its toll on M22. You should see it from the southern hemisphere.

M24, which can be seen with the naked eye from a dark site, is a "star cloud" and is not a deep-sky object as such. It is, however, one of my favorite targets with a rich-field telescope. M24 was simply amazing through a 22" Starmaster at the Southern Skies Star Party in Bolivia last June.

Dark skies are any telescope's best friend, Ron.

Experienced observers like Jay Reynolds Freeman have logged the entire Messier list through binoculars. I've seen 80 of them myself with binos without going to extreme measures.
