Messier 108 – The Surfboard Galaxy

Messier 108 (M108), nicknamed the Surfboard Galaxy, is a barred spiral galaxy located in the constellation Ursa Major. The galaxy lies at an approximate distance of 45.9 million light years from Earth and has an apparent magnitude of 10.7.

Tech Specs: This image is composed of 27 x 60 second images at ISO 3,200 with 5 x 60 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. Guided using a Canon 400mm lens and ZWO ASI290MC camera. Imaging was done on February 26, 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.

The Eskimo Nebula – NGC 2392 in Gemini

Here is a quick 15-minute exposure of the double-shell planetary nebula called The Eskimo Nebula or NGC 2392. It is located in the constellation Gemini and is about 2,900 light-years away at a magnitude of 10.1. I need more exposure time to bring out the filaments in the outer shell to make it look like a face surrounded by a parka hood.

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 (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 18, 2017 from Weatherly, Pennsylvania.

Messier 81 – Bode’s Galaxy in Ursa Major

Here is a 53-minute exposure of the large spiral galaxy known as Messier 81 (M81 or Bode’s Galaxy). It is referred to as Bode’s Galaxy as it was first discovered by Johann Elert Bode in 1774 and later picked up by Messier and added to his catalog. The magnitude is listed at a bright 6.9 and the distance is about 11,800,000 light-years.

I was particularly happy with capturing some of the dust clouds on the inner spiral arms during this imaging session, hoping to add more data on a later date.

Tech Specs: This image is composed of 53 x 60 second images 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 26, 2017 from Weatherly, Pennsylvania.
