Utterly unedited, uncropped photos of Venus and the Moon, both with 8″ reflector telescope and 25mm eyepiece, (65x magnification), so you may see the apparent size comparison:

2:21 PM CST 11-29-11 (20:21 UT). Venus is still further away from us than the Sun is, and will appear much larger when the June 5, 2012 transit approaches.

2:27 PM CST 11-29-11 (20:27 UT). The crater Langrenus may be discerned right in the middle of the lit part of the Moon.

Cell phone camera + toy microscope = a new adventure that’s only just beginning:

Many must have seen the lovely, thin waxing crescent Moon this evening, as I’ve had many hits from people looking for 11-27-11 Moon photos. Alas, I have none. It was cloudy most of the day, and when it cleared off in the evening, I had just one beautiful glimpse of it minutes before moonset, through the panoramic picture window of a loved-one’s hospital room; but only a glimpse, because I was not there to gaze out the window.

Being eager to please, I’ll offer this hazy-but-passable shot of the Moon at the same illumination (11%) at 9:48 PM CDT 6-4-11 (2:48 UT 6-5-11):

Io zips around Jupiter in only 1.77 Earth day, Europa in 3.55; Ganymede orbits in 7.16 Earth days, and Callisto in 16.69. Thus Io does the most disappearing and reappearing, though they all do it from time to time:

Above: 10:15 CST 11-27-11 (4:15 UT 11-28-11). Left to Right: Ganymede, Europa, Jupiter, Callisto.
Below: Exactly one hour later at 11:15 CST, Io has popped out of Jupiter’s shadow. Left to Right: Ganymede, Europa, Io, Jupiter, Callisto.

All with 8″ reflector telescope and 25mm eyepiece.

“And now for something completely different,” just this very evening I’ve expanded my horizons to include Inner Space as well as Outer Space:

A dash of Real Salt, magnified thirty times with this old Lionel toy microscope that I’ve had for eons:

All with my usual LG VX8360 cell phone camera. Click for larger view.

Below: The Concordia Choir performs Eric Whitacre’s Lux Aurumque (“Light and Gold” in Latin) at the 2005 Christmas Concert of my alma mater, Concordia College, Moorhead, Minnesota

My college and others like it are preparing now for this year’s Christmas concerts, and I love seeing and hearing each new group of young people participating in this timeless tradition. Some, like the angelic-voiced young woman in the video, take on prominent leading roles; hundreds of others simply are voices in the chorus. There are a number of choirs and other ensembles involved in the Christmas Concert, some more prominent than others; but each voice is important, and I, for one, would rather be a small part of something big, excellent, and meaningful, than to be a big part of something mediocre. Believe me, I’ve experienced both.

Throughout college I was involved in the Orchestra as well as the Fargo-Moorhead Symphony, but I was in the big Christmas Concert just once, during my senior year in 1986, which happened to be Dr. Clausen’s first year as director of the Concordia Choir, and he was the first one to introduce the Orchestra into the Christmas Concert. Thanks for including me, Dr. Clausen!

Kinda reminds me of this song:

As of Thanksgiving night, 2011, the retirement village over yonder has their outdoor Christmas tree lit once again. With no magnification:

With the 60mm refractor telescope and 25mm eyepiece (28x magnification):

This morning, with the 8″ reflector telescope, 17mm eyepiece and 2x Barlow (191x):

The following crowds were gathered on Thanksgiving Day, but they appeared quite serene and completely unaffected by “Black Friday” hype:

Now to astronomy: Jupiter and the Galilean moons at 12:24 AM CST 11-24-11 (6:24 UT), with the 8″ reflector and 17mm eyepiece. From left to right: Callisto, Jupiter, Europa, Io, Ganymede:

These days, just after sunset, you will see Venus shining brightly in the southwestern sky, and Jupiter shining much higher in the eastern sky. Keep watching, because during the next few months they will treat you to a striking spectacle. Evening after evening they will draw closer together until they make a magnificent conjunction high in the western sky after sunset in mid-March. Then, even after Jupiter fades into the sunset, Venus will continue to blaze brightly until the upcoming historic Venus transit on June 5, 2012. You may learn more about the transit here, and much, much more about it at www.transitofvenus.org/

As a “preview of coming attractions,” here’s a table of my previous Venus observations, with my recent 11-20-11 Venus photo added at the bottom:

About 2:30 PM November 21, 2011:

Our first lingering snow of the season has fallen, but a nearby warm water discharge keeps ducks and geese in the neighborhood all winter.

Pluto investigates signs of webbed-feet activity.

To my eye these duck footprints in the snow are creating a multistable perception effect. How about for you?

I’m sharing this for no other reason but that it’s utterly fun, and groovy, man! Far out! Outta sight!
