What a nice night for wind

The Clear Sky Clocks (www.clearskyclock.com) were showing a clear sky for last night. I decided to prep the Astronomy Vehicle and head up on the mountain. As soon as I hit the top of the mountain, the wind became very notable, and slightly angry. I decided to proceed to the observing site, hoping that the wind would not be as bad on that side of the elevation. Upon arrival it did seem to be a bit protected, so I started to set up. I had the heat going and several tripods set when the first big gust came through. I figured it would be an occasional thing, so I continued to set up under dark skies, while the thin crescent moon continued to set. Suddenly, in the distance, I heard a truck driving down a nearby highway. It was odd because I have never heard a truck driving down that highway before tonight. Then, as the trees started to rustle and bow, I realized it wasn't a truck but a large gust front heading my way. I ducked inside the warm bus just in time as the massive gust of cold wind slammed into the vehicle and rocked it steadily for almost a minute. That gave me all the time I needed to decide that I wasn't going to be able to do any astrophotography in these conditions and observing would be in question as well. So I loaded the tripods back up into the vehicle, turned off the heat, and headed back down the mountain. That wasn't the first time that happened, and it certainly won't be the last. But, nevertheless, it is hard to leave clear skies, especially when they are hard to come by in this area.

Merry Christmas to all

Merry Christmas to everyone. I hope you all have a great holiday season, and you take some time to gaze at the heavens.

I was awarded an Astronomy Grant

In case no one noticed, it has been rather cloudy lately, so the astrophotography opportunities have been very slim. I fully intend on taking advantage of any opportunities as they come available. I received great news this month. I received a grant from a group in California, called the Riverside Telescope Makers Conference (RTMC). It is called the Clifford W. Holmes Grant, and it is given to people who are actively involved in astronomy outreach. My submission for the grant was through my use of my Astronomy Mobile Outreach Vehicle (AMOV). I use the vehicle to help me carry telescopes and equipment to astronomy outreach programs in the area. I will be purchasing a solar telescope with this grant so I can expand my solar programs. I am pleased that this group has recognized my efforts, and I thank them for their assistance in helping me bring astronomy to the Roanoke Valley. The solar telescope will also be used at outreach events held by the Star City Astronomy Network, a local group of astronomers dedicated to observational astronomy, and astronomy outreach.
Keep hitting the blog for new images as I shoot the night skies.

Images from Late November

The stars and deep sky objects of winter are starting to make their way into the night sky. Among some of these objects are the brightest star in the night sky, Sirius, or alpha Canis Majoris. Also, one of the few naked eye nebulae, M42, the Orion Nebula, is prominent as the center star in the sword of the constellation Orion, the Hunter.
Of course, the beautiful open cluster, Pleiades (M45), is prominent in the zodiacal constellation, Taurus, the Bull.
Still in the sky is the Andromeda Galaxy, M31, overhead and working its way into the western sky late in the evening. Below are some images I shot on November 26, 2008.


This image is of the Double Cluster in the constellation, Perseus. You can see the two distinct clusters in this image.
Camera - Canon EOS 40D
Lens - Sigma 300 MM f2.8 Lens, set at f3.5 - ISO 800 - (480MM effective focal length)
15 Minutes of exposure (15 x1 minutes)

This image is of M45, the Pleiades Cluster in the constellation Taurus. The gases around the stars reflect the starlight. Therefore, the nebulosity around the stars are called a reflection nebula.
Camera - Canon EOS 40D
Lens - Sigma 300 MM f2.8 Lens, set at f3.5 - ISO 800 - (480MM effective focal length)
30 Minutes of exposure (10 x3 minutes)

The center of this image is M42, the Orion Nebula in the constellation Orion. The gases around the stars are excited by the radiation from the embedded stars, and glow. Therefore, the nebulosity around the stars are called an emission nebula. It is a stellar nursery, and the bright stars in the center of the nebula are "baby stars".The Orion Nebula is to the right, and the "Running Man" Nebula is to the left. Notice the difference in the colors of these two nebulae. The "Running Man" Nebula is a reflection nebula, usually indicated by the bluish color.
Camera - Hap Griffin Modified Canon EOS 350D
Lens - Sigma 300 MM f2.8 Lens, with a matched 1.4x Teleconvertor, set at f4 - ISO 800 - (672MM effective focal length)
5 Minutes of exposure (10 x30 seconds) +
20 Minutes of exposure (10 x2 minutes) +
27 Minutes of exposure (9 x3minutes)
Total of 52 munites of exposure

This image is of IC 2118, the Witch Head Nebula in the constellation Eridanus. This is also a reflection nebula, with the dust reflecting the light from the bright, supergiant star, Rigel (Beta Orionis), the lower-right star in the constellation Orion. This reflecting dust lies 40 light years from Rigel, and about 700 light years from us.
Camera - Hap Griffin Modified Canon EOS 350D
Lens - Sigma 70-200MM f2.8 zoom lens, set at 200MM, f4 - ISO 800 - (320MM effective focal length)
