Teapot of Sagittarius

Here is a view of the teapot section of Sagittarius taken early this morning, May 8, 2017.  This is about as high as it will get in the skies of Carbon County, Pennsylvania.  Looking forward to capturing some nice deep space objects later this year.

Tech Specs: Canon 6D, Canon EF70-200mm f/2.8L USM lens, ISO 3200, 3 x 8 seconds, f/2.8, 70mm, tripod mounted. Date: May 8, 2017. Location: Weatherly, Pennsylvania.

On a side note, this is my first attempt at manual stacking in Photoshop.

Poor Transparency on March 21, 2017

I tried setting up last evening, March 21, 2017, with no luck. While the skies looked good overhead (visually) and there were clouds around the horizon, I decided to try and shoot some images of M95 in Leo. The first 60-second image showed me how bad the transparency was. High level, thin clouds covered the sky which I failed to see before setting up. After I broke down the telescope, I captured this image showing the light cloud cover in the area as an example of bad transparency.

Tech Specs: Canon 6D with a Samyang 14mm f/2.8 lens, tripod mounted. Single 20 second exposure, ISO 1600, 14mm, f/2.8, Imaging was done on March 21, 2017 from Weatherly, Pennsylvania.

Corvus the Crow

The constellation Corvus reminds me of two things, an upside down “keystone” and the famous Sombrero Galaxy (actually in the constellation Virgo just across the border). Personally, I see no crow, raven or any other bird-like figure in this constellation.  Corvus ranks 70th in area out of the 88 constellations.

A special thank you to the U.S. Naval Observatory and the Space Telescope Science Institute for the graphic of Corvus used in my image. The illustration was obtained from the 17th century Firmamentum Sobiescianum sive Uranographia star atlas by Johannes Hevelius.

Tech Specs: Canon 6D with a Canon EF70-200mm f/2.8L USM lens tripod mounted. Single 8 second exposure, ISO 3200, 70mm, f/2.8, Tiffen star filter. Imaging was done on February 3, 2017 from Weatherly, Pennsylvania.
