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.

NGC 6879 – A Compact Planetary Nebula in Sagitta

I wasn’t sure what to expect from imaging this planetary nebula, most images I found only showed a small blue dot. It looks like I ended up with the same type of image. This planetary nebula is found in the constellation Sagitta and is magnitude 12.5, and very small. Cropping, zooming and manipulating the planetary nebula region revealed no details.


Tech Specs: This image is composed of 60 x 15 second images at ISO 3,200 with 5 x 15 second darks and 5 x 1/4000 second bias frames using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount. Imaging was done on October 5, 2016 from Weatherly, Pennsylvania.

He’s Back in the Evening Skies – Mighty Orion

I think it is safe to say that Orion is officially back in the Northern Hemisphere evening skies – can’t wait to do some imaging. I’ve already been seeing a lot of nice images of the Orion Nebula and the Horsehead Nebula. My first imaging session is going to be the planetary nebula NGC 2022 located near the head of Orion.


Tech Specs: Tripod mounted Canon 6D and Canon EF70-200mm f/2.8L USM lens, two exposures combined using Microsoft Image Composite Editor, each image was 10 seconds, ISO 3200, f/2.8, 70mm. Photo taken on November 22, 2016 from Weatherly, Pennsylvania.

Canis Major in the Early November Morning

Here is an image taken on November 2, 2016 showing the full constellation view of Canis Major as seen from the Northern Hemisphere, it is sitting right at its peak elevation in Pennsylvania. If you are view this on Facebook I have included both the lines and unlined version of the photo. Light clouds seemed to frame the area around the constellation for a short period of time.
