Asteroid Ceres

Posted By Dave Mitsky
Off the top of my head I can recall seeing 1 Ceres and 4 Vesta (which is visible to the naked eye) through binocs. A number of others are bright enough at opposition to be seen thusly - http://www.jas.org.jo/ast.html

Who Invented the "Newtonian Reflecting" Telescope?

Posted By Dave Mitsky
Phil Rounesville built a 6" f/31.2 Gregorian (Sky & Telescope, January 1992, pages 16-17) that is usually on display at the Stellafane Convention. I've looked through it a number of times at Saturn and other targets appropriate for its long focal length.

Here's an image of a Gregorian of antique vintage:

Jeff,

That is without a doubt one of the finest amateur shots of B33 that I've ever beheld.

Visual observation of Encke division?

Posted By Dave Mitsky
I believe I saw the Encke Division on the morning of December 31st using a 17" classical Cassegrain at magnifications up to 404x. The seeing was very good indeed.

A new supernova in M51?

Posted By Dave Mitsky
There's no mention of it at http://www.rochesterastronomy.org/snimages/

Could it have been an asteroid perhaps?

Colourful DSOs?

Posted By Dave Mitsky
I certainly agree with Maurice concerning the Jewel Box Cluster.

Other colorful objects not mentioned include IC 418 (the Raspberry or Spirograph Nebula), the Homunculus Nebula (a distinct orange), NGC 40, NGC 1535, NGC 6369 (the Little Ghost), NGC 6445, NGC 6210, and NGC 6826 (the Blinking Nebula).

Nowadays seeing is NOT believing.

Favorite Southern Targets

Posted By Dave Mitsky
In addition don't miss Gamma Velorum, NGC 2477, IC 2602, NGC 3532, NGC 4755 (the Jewel Box), NGC 5128 (Centaurus A), and especially NGC 5139 (Omega Centauri). The Coalsack Nebula is a great binocular object.

There are a lot more worthy targets on these lists:

Orion's missing arrow

Posted By Dave Mitsky
The arrow-shaped Collinder 65 is in that general region but I'm not sure that it's what you saw.
