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.

The Cigar Galaxy and Bode’s Galaxy in Ursa Major

Here is a combined view of the Cigar Galaxy (M82) and Bode’s Galaxy (M81) taken during imaging session in February 2017.

Tech Specs: Bode’s Galaxy (on the right) composed of 53 x 60 second images, Cigar Galaxy (on the left) composed of 28 x 60 second exposures. All at ISO 3,200 with 5 x 60 second darks and 5 x 1/4000 second bias frames (captured using BackyardEOS software) using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount. Guided using an ASI290MC mounted on a Canon 400mm f/5.6 lens using PHD2 software. Imaging was done on February 20 and 26, 2017 from Weatherly, Pennsylvania. Manually aligned.

Globular Cluster NGC 2419 in Draco

Here is a view of the most distant globular cluster in the Milky Way, NGC 2419, some have postulated that this may be an extra-galactic object. I have seen distances as high as 285,000 light-years distant. It appears small and dim, but it is actually very large and very bright (if it was a bit closer to us), there are estimates of 300-400 million solar masses in this cluster.

Tech Specs: This image is composed of 44 x 30 second images at ISO 3,200 with 5 x 30 second darks and 5 x 1/4000 second bias frames (captured using BackyardEOS software) using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount. Imaging was done on February 19, 2017 from Weatherly, Pennsylvania.
