That filament was very striking around 19:40 UT during my second observing session with my new Coronado PST.

Posted By Dave Mitsky
I was at CSSP this past weekend. I'll be there next month for the BFSP as well.

Russ,

I spent some time with your group last year and I'd certainly like to have the use of one of your binoviewers during this year's BFSP.

Pluto observation from BFSP - Sep 11-12 2004

Posted By Dave Mitsky
Doug,

Tony Donnangelo and I also observed Pluto during the BFSP. We used his 14.5" Starmaster Sky Tracker Dob and had no trouble picking it out among the very dim field stars shown on Tony's computer generated chart. It was much easier to see than it was three weeks earlier when we also viewed it from CSSP. A number of our campsite neighbors had no difficulty seeing it when we coached them on exactly where to look.

I usually have little trouble detecting Pluto under magnitude 5.0+ skies with the 17" classical Cassegrain at the ASH Naylor Observatory in Lewisberry.

Phil Harrington has seen B33 from the Winter Star Party using a 80mm binocular with H-beta filters attached.

What am I seeing?

Posted By Dave Mitsky
Sarah,

The change in colors is a result of atmospheric dispersion. Here are some links on the phenomenon:

What Can I Expect to See Through an 8" SCT?

Posted By Dave Mitsky
You may be expecting too much from an 8" SCT. The effects of increasing aperture are simulated in an approximate manner at http://www.globaldialog.com/~obsessiontscp/m13page.html

See true spirality in M51 is not that easy a task. Dark and steady skies are required, as well as a fair sized aperture, some say 12.5".

HELP! What was I looking at?!

Posted By Dave Mitsky
Do these sites narrow it down any further?
