Oh, well

Well, last night was not as clear as the previous nights. The moon was easy enough, and we did get to see Mercury through one of the telescopes before sunset (so it was still relatively high in the sky), but the haze and clouds moved in and you couldn't see it. You can see how the moon's light is diffused through the haze... See also how much the moon moves from one night to the next? Compare to Tues night.

But since we were out there, I did get some pics of the moon through my telescope ... The horizon is not great, so I couldn't get Mercury in mine. Besides which, it would still have only shown up as a dot in a photo through that scope. So here's the moon...

Why is the sky so dark considering the time I took it? Well, I applied auto-color in PS7...

Moon and Mercury

Monday night was also clear, but we had open house. Last night (tue), I had a student intern working his last night. Although it was clear, we were both working on computers inside analyzing images (me, the asteroid pics I took Sun night). About 8:50, I remembered something, jumped up, and headed outside. Had to run up the hill of our parking lot and over some to get the right angle. You can see the nice little crescent moon. Look at the larger version and you'll see Mercury as the little "star" down and left of the moon. Once I saw that I could see the Moon and Mercury, I hollered to my intern so he could take a look. Then I went about rushing to get my camera setup because of course it was all setting very quickly and as you can see, I don't have a good horizon in that direction!

I also wanted to get some zoomed in shots, so I connected the camera to my Orion Shorttube 80. By this time, they had disappeared behind the tree line so I had to go over into the landfill which has higher ground... just enough to get a few more shots...

Tonight (wed), the moon will be above Mercury and getting closer to Mars...

Up already, why not?

So, since I got home pretty late Sunday night (more like early Monday morning), I took a short 30 minute nap, then went to the roof to take a pic of this -7 IR Flare. Remember, this is from Alexandria... inside the Beltway... lots of light pollution... and processed in PS7, hence the metallic look. Jupiter is the bright object off to the right, the flare is what looks like a shooting star. From my perspective, this was a very slow moving flare, so the exposure ended up a bit longer and the stars had time to trail.


Here's an 'unprocessed' version to be fair...

Rare Night, pt 2

Well, Saturn is also visible. It's over by Regulus in Leo. Okay, the pics don't look great when they're small like this... It's a short exposure and there's light pollution. Click on it to get a bigger version.

Saturn is farther away than Mars, so it's motion against the background sky is not as noticeable. But if you pay close attention you'll see Saturn starting to drift away from Regulus.

Rare night

Sunday night was a rare one... clear, dark... couldn't pass it up so I went out to the observatory to image some asteroids (no luck on those). While there I also took some sky shots.

This shows Gemini with Mars just to the left of Castor and Pollux. They look like they're in a straight line almost (Mars -- Pollux -- Castor). Well Mars is moving and the alignment will change over the coming weeks. In the full size image, you can also see M44, the Beehive Cluster, in the upper left.

Fri (9 May) evening, the crescent moon will be below Mars. For some parts of the world, the moon will occult (eclipse) Mars during the night (but it won't be visible from east coast USA). Saturday evening, the waxing crescent moon will be above Mars and just below the cluster (use binoculars).

Although the sky is slowly setting, Mars is drifting east. On May 19, Mars will be at the corner of Cancer. And over the next several nights, it will drift through the small constellation and through the Beehive Cluster. That will be a nice photo op!
