M51 Supernova

Posted By Dave Mitsky
After watching the Harrisburg fireworks last night, I observed SN 2005cs with the ASH 17" f/15 classical Cassegrain under less than ideal skies. Using magnifications of 249 and 259x, I was able to see the supernova and the two field stars more or less bracketing it with averted vision.

Recent Tempel Observations?

Posted By Dave Mitsky
My friend Tony Donnangelo and I may, and I stress may, have seen the comet on Saturday night at the Green Bank Star Quest II using his 14.5" Starmaster.

David,

This is a fairly well-known object, which was christened with the nickname of the Muscleman Cluster by the veteran observer John Davis. Phil Harrington mentions it in a couple of his books I believe.

M51 Supernova Visual observation

Posted By Dave Mitsky
My friend Tony Donnangelo and I observed SN 2005cs again on Saturday night from the grounds of the NRAO at Green Bank. We also viewed SN 2005cf in Libra again that night. We used Tony's 14.5" Starmaster Sky Tracker Dob.

"Bivalent" Eyepieces

Posted By Dave Mitsky
Hybrid eyepieces have a 2" skirt for reasons of safety and convenience. The clear aperture is limited to that of the 1.25" barrel and the field stop of the ocular so the answer to your first question is no.

Has anyone mentioned the new Orion Express 80mm f/6 "semi-apochromat"?

Mars as big as full moon!

Posted By Dave Mitsky
This "rumor" been making the rounds for some time now. The OP apparently mixed up the 2003 and 2005 Martian oppositions. The original message stated that Mars would appear as large as the Moon does to the naked-eye at a magnification of about 75x, which was correct for the 2003 opposition.

An interesting experiment and some SSO's

Posted By Dave Mitsky
Inge,

Anything outside of the solar system should be considered a deep-sky object, even individual stars.

Objects in Cygnus

Posted By Dave Mitsky
The North America Nebula (NGC 7000), the Pelican Nebula (IC 5067-70), the Cygnus Loop (Veil Nebula complex), and the Northern Coalsack (B348-9) come to mind.
