May’s Moons

Sunday, May 31st, 2009

This has been such a cloudy month, but even when it’s cloudy, I like to get out and find something to enjoy.  That usually means the Moon.  Fortunately, I did have one decently clear night night where I was able to image the Saturn-Moon-Regulus alignment.  I also remembered to capture Luna at first-quarter – typically not so exciting, but last night’s first-quarter moon was the second this month.  You can click on each of the images for larger versions.

This image is from May 27, when Luna was 17% illuminated and about 3.5 days old.  Imaging specifics were 1/60 sec., f/5.6, ISO-200, 300mm:

This is the same view, taken about about twenty minutes later, when the clouds had really moved in.  I was taken with the image’s sketch-like appearance.  Imaging specifics were 0.6 sec., f/5.6, ISO-800, 300mm:

Taken three days later, this image reveals May’s second first-quarter moon.  This month’s first first-quarter moon occurred on May 1.  Imaging specifics were 1/500 sec., f/5.6, ISO-200, 263mm:

Finally, the Moon with Saturn and Regulus in Leo.  Saturn is the golden-hued “star” above Luna; Regulus is the blue-tinted star immediately right of Luna. Imaging specifics were 8 secs., f/4, ISO-800, 18mm:

My Favorite Kind of Moon

Monday, March 9th, 2009

I love observing the moon as much as any astronomer, but let’s face it, Luna poses a real and regular problem for night sky observing. A daytime moon is a different story – (almost) equal opportunity for lunar landscape browsing without all that bothersome moonlight to diminish the fainter deep sky objects! (You can click the image for a full-size version and click the x to close.)

Now see, isn’t the moon just as lovely in a sunlit sky? I took this image yesterday, when the moon was at 94% illuminated – nearly full. In North America, March’s full moon is traditionally known as Full Crow Moon, Full Crust Moon, Full Sugar Moon, and Full Sap Moon. Knowing that these names originated with the Native American culture, you can probably guess what each one references.

Image Specs: Canon XTi/400D, f/5.6, 1/800 sec., ISO-100, 300mm, two images stacked – 1 w/ foreground focus, 1 w/ background focus.

Coincidentally, as I write this, the Kepler Mission team is announcing on Twitter that the Kepler craft just passed the Moon’s orbit, as it makes it way out of the Earth-Moon system. Go Kepler!
