People's Astronomy: November 2011
http://pchris00pnc.blogspot.com/2011_11_01_archive.html
Stories about astronomy and people. Thursday, November 17, 2011. Solar Filter Project, November 15, 2011. Never Look at the Sun Through a Telescope Without a Proper Solar Filter. When my Astrozap solar filter. At this point, I still hadn’t cut the film. I wasn’t committed to anything. I could wait and find something better, or I could cut, and live with it. I cut. I should. Note: I did have to re-glue everything Wednesday. I don't know if I didn't use enough glue the first time, if it was the cold we...

People's Astronomy: Mare Orientale, Finally
http://pchris00pnc.blogspot.com/2015/02/mare-orientale-finally.html
Stories about astronomy and people. Thursday, February 19, 2015. Mare Orientale, Finally. My previous post was about observing the the celestial western limb. Of our Moon with both favorable libration and illumination. I haven't been as lucky with the celestial eastern limb. Twice this year so far, in January and February, I've managed to observe Mare Orientale with favorable librations. Visually, I was very pleased with the view, although I didn't manage to improve much upon my images from last month.

People's Astronomy: December 2014
http://pchris00pnc.blogspot.com/2014_12_01_archive.html
Stories about astronomy and people. Friday, December 26, 2014. My Best Look Ever at the Celestial Western Lunar Limb. How many times have we heard or read that the half Moon is the best time for lunar observing? I observed over the course of many hours, and watched as features near the terminator disappeared into lunar night. While atmospheric transparency was never great that night, toward the end of the observation it was terrible, and water vapor in the air started turning the images very soft. As usu...

People's Astronomy: October 2011
http://pchris00pnc.blogspot.com/2011_10_01_archive.html
Stories about astronomy and people. Monday, October 31, 2011. Io Transit, Ganymede Occultation, October 27-28, 2011. To get the best images I could, I used the 16” LX200 at Conway Observatory. I used my own 25mm 1.25” eyepiece with a 2x Barlow lens, because that particular eyepiece is easiest to use with my point and shoot camera. For most of the images I used a yellow filter (I think #12? To reduce the glare from Jupiter, without dimming Io and Ganymede too much. Curt's predicted events times. Io Transi...

Lucky Sundogs & Other Atmospheric Phenomena: Colorful Circumzenithal Arc
http://luckysundogs.blogspot.com/2014/12/colorful-circumzenithal-arc.html
Friday, December 26, 2014. I walked out the door late this morning, and upon seeing cirrus type clouds to the north, immediately looked up. I saw this spectacular circumzenithal arc, and could not get my phone out of my pocket and unlocked fast enough. It didn't last long, only a few minutes, but it may have had the most vivid colors of any circumzenithal arc I've seen this year. Subscribe to: Post Comments (Atom). Working to bring astronomy to the public. View my complete profile.

Stories about astronomy and people. Thursday, March 29, 2012. Messier Marathon March 16-17, 2012. Gear out, and ready for the night. Larry sets up his truss tube Dob. Quick solar observing for me. Roger works the 16" LX200. Jim and Jeff wait their turn. FINALLY. Observing time. I really wanted to start the night off right by catching the faint galaxies of M74, M77, and M33. Jeremy had all but given up on them, but managed to track down M31 and companions. I was struggling with it, and gla...At 9:01 I log...

People's Astronomy: May 2012
http://pchris00pnc.blogspot.com/2012_05_01_archive.html
Stories about astronomy and people. Tuesday, May 22, 2012. Lunar Connection to the June 2012 Transit of Venus. I wanted to do this as a regular post, but it was going to take too much time to copy and paste everything together. Instead click the link in the title to see a post I wrote on Chicago Astronomer. Now that the Moon is back in the evening sky for the last two weeks before the Transit of Venus, the idea is to observe some lunar features named after people who have contributed to transit science.
