Hello, Thanks to data provided by Alister Ling, few days ago from San Rafael (Mendoza, Argentina) with Rodolfo Ferraiuolo, we successfully observe the "Lunar...
Greetings, I'm doing some research on the Great Attractor and the Shapley Supercluster and, as often is the case, am coming across different figures for their...
... I observed SN 2009dd a number of times during April from several different sites. Instruments used were an 8" APM refractor, a 10" modified Meade Dob, a...
Part of the problem may be defining just what is being called the GA and Shapley supercluster. Although it may be an outdated idea, the old lore was that ACO...

... Brian, Thanks for that information. 230 Mpc puts the GA far more distant than the figures I've seen. What about ACO 3627, which appears to be...
... I'm mis-remembering---shoulda looked it up! Yes, ACO 3627 is the rich Norma Cluster that is thought to be the nexus of the Great Attractor. NED indeed...

The supernova in NGC 4088 was a fabulous sight through a 28 inch Newtonian on April 18th and 21st, but the surprise to me was how much detail is visible in the...
Howard, Even with my 12" dob I thought I could make out subtle details in NGC 4088. The galaxy appeared S-shaped due to dark clouds and low contrast of the...
I used a 24-inch f/16 Boller & Chivens telescope on the evening of April 21 to give a night sky tour to a group of 25 students.? Once the sky was dark, I...
Greetings all, So it's been almost a year since I brought up this observing challenge. Has anybody else tried for Hewett 1 since then? After another great...
Hi Scott, Enjoyed reading your post about Hewett 1 and the asterism you came across in Sextans. Over at the Deepskyhunters, deepskyhunters@yahoogroups.com we...
Thanks Dana, That was just what I was looking for. The first hit in a Google search of “Lorenzin 23” comes up with the nickname “The Cerberus”. But a...

Hi Scott, That's pretty neat what you came up with. A three headed watchdog? Well, Tom Lorenzin must've seen more than just the line of stars to come up with...
Bill Liller in Chile has discovered what's likely to be an ordinary nova in the LMC. Today Berto Monard in South Africa has measured an accurate position: 5...

We've been having some nice seeing in the late afternoon when we crank up the 60cm Clark refractor for public viewing of Saturn. I've been managing to find...

The first time I noticed the disc of Titan was in 1993, Brian was a mere 20 feet away from me. It was our first of 12 nights of visual observing at Las...
Hi Scott, I call the bottom of the chain plus a line of stars east, Dana's V. Dana Patchick, who already wrote to you, pointed it out to me long ago. As Dana...
Thanks Sue, Rinnan’s Run. I guess if I’d been more diligent two months sooner when I noticed it at the Winter Star Party, it might have a different name....
... I took a quick look 4 years ago with an 18-inch and easily picked up the brightest 3 members (ESO 137-6/8/10) of the highly reddened ACO 3627. Even in a...
While watching to see if the current active regions on the Sun produce an actual sunspot (not really, so far), I notice that the Pleiades are coming into view...

This SOHO field of view is my favorite one - more precise the field in which Sun will appear on May 29th. Then stars north of Hyades (some of them genuine...

Hello Mel, ... That is indeed another possibility! But in my case, I 'know' that the sun is closing the horizon every day. The question is can one really...
It seems that way to me too. I see a gradual darkening of the sky up to about the point where the sun passes below an altitude of -18 degrees (or so--it varies...
