Hi, Saw a very lovely view from my hometown a minute after sunset and a couple of minutes before unseasonal clouds sealed off the ceiling of the sky. My...
A CBET announcement this morning indicates that V1647 Ori and the related McNeil's Nebula are again in an outburst state, about as bright in the near-IR as it...

Question - With a 20" is it possible to see a Saturn moon's shadow transit across Saturn? If so, when? Dan...
I thought about this subject earlier this year, as I hope to image one some day next year. I posted a summary to Cloudynights. The table is specific to...
Dan, Good question! According to GUIDE, there are quite a few of the moons that will actually cast a shadow on Saturn's cloudtops, but they are all pretty...
William Rutter Dawes recorded/drew shadow + disk transits of Titan a number of times during the mid-19th century. He was using a 6-inch refractor. As for some...
Tom - Thanks for your response. I went to your Cloudy Nights site. Since I observe around Kansas City looks like I won't be able to see a Titan shadow transit...
From Jean Meeus, here are the UT times of Titan and Rhea shadow transits. Note that the times will be the same no matter where you are on Earth because it is a...
Wow - thanks Jean! Dan ... transits. Note that the times will be the same no matter where you are on Earth because it is a shadow on Saturn, not a moon...
The "tadpoles" in NGC 410 are striking in images, e.g. at http://apod.nasa.gov/apod/ap060815.html The surface brightness looks good. But the "heads" are less...
I was observing the IC 410 region about 2 months ago with my 10-inch under alpine skies (ZLM ~7.0). While the northern tadpole was not visible at all, the...
Hi Bob, the brigther one is not as difficult in medium to large dobs. I had observed it with 14" and 22" without problems under average skies using filters. In...
I used the JPL Horizons site to create a couple figures that show the changing inclination of the rings of Saturn in coming months. I was aware that the rings...
Hi all, Thanks again for another year of sharing Astronomy. Have a lovely season and I wish you all just the very best of stars for the New Year 2009. Magda ...
15480 Empire Rd. Benson, AZ 85602 hm ph: 520-586-2244 Thanks, Magda. The best to you and everyone on these lists. Can another year have passed so quickly? This...
Maybe Jean can help me with this too. We've all know since childhood that Marvin the Martian is trying to destroy Earth because it blocks his view of Venus,...
Of course Jean has been asked about mutual planet occultations as seen from other planets before and he has written about it: Morsels III p 305. He only...
Winter is beginning to rear its head. We're getting snow in the surrounding mountains and windy, cloudy weather for awhile. Clear skies and Happy Holidays, ...
Before anything, Merry Christmas to all and Happy New year! I was testing some shots with a Orion SkyGlow filter and took these pictures of Betelgeuse with...
Hi Celso, you will have to give a link to a site, because this list server does not permit image attachments. There are many possibilities for reflections in...
I am in the process of writing a piece for the Webb Society on the Holmberg galaxies and was wondering what observations might be around of them. I only have...
I also observed Holmberg II = UGC 4305 and the observation was published in the Webb Society journal in the article that was called something like "Seeing...

Hmmm, I also told Owen that I vaguely remembered someone doing a piece covering the Holmberg galaxies in Deep Sky or possibly the Webb Society journal in the...
There was something Ronald Stoyan did in Interstellarum a long time back but I can't find that piece but I will keep looking. Anyway as requested here are the...
Owen, in 2002 I took pictures of Holmberg I-XI My Camera a ST7XE my telescope a 12" newton f/4,8 I can send these pictures via email to you. These are the...
Owen, I've never pursued Holmberg galaxies, but I have one of them anyway and a very weak maybe on another. UGC 4305 254/1494mm Newt, 213x Very faint, fairly...
The supernova hunters are busy in the morning sky. An event has been reported on CBET 1636 in the bright galaxy Messier 61. It was discovered by Koichi...

Dear Owen, see my book "Galaxies and how to observe them", p. 161. CS, Wolfgang...
Friends, The veil was real, but not in the interstellar Milky Way but most probably in the Earth's atmosphere. I took more pictures of Betelgeuse and ...
