Messier 97 – The Owl Nebula

The Owl Nebula (also known as Messier 97, M97 or NGC 3587) is a planetary nebula located approximately 2,030 light years away in the constellation Ursa Major. The owl-like appearance is caused by various formed shells expanding away from the central star.

Tech Specs: This image is composed of 23 x 60 second images at ISO 3,200 with 4 x 60 second darks and 4 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 April 14, 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.

NGC 2438 – Planetary Nebula in Puppis

NGC 2438 is a planetary nebula found inside the open cluster M46 in the constellation Puppis. I remember the first time I imaged M46 and spotted this fuzzy planetary nebula, I thought I discovered something new! My star atlas, at the time, did not show this NGC object. This planetary nebula is actually not part of the open cluster, it just appears in the same line of sight. It’s estimated distance is 3,000 light years away and has a magnitude of 10.8.

Tech Specs: This image is composed of 40 x 15 second images at ISO 5,000 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 February 18, 2017 from Weatherly, Pennsylvania.

NGC 2022 – Planetary Nebula in the Constellation Orion

NGC 2022 is a small planetary nebula found in the shoulder of the constellation Orion, it is roughly 6000 light-years away and is roughly ½ light-year across. The magnitude is listed as 12.0.  I did manage to capture some details inside this PN.

Tech Specs: This image is composed of 104 x 15 second images at ISO 5,000 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 December 27, 2016 from Weatherly, Pennsylvania.

NGC 2372 Planetary Nebula in the Constellation Gemini

Here is a different looking planetary nebula designated as NGC 2371 and 2372 found in the constellation Gemini. You can just start to make out the “wings” on either side of this nebula with a 14-minute exposure. Distance to this is listed at 4,400 light-years.

Tech Specs: This image is composed of 56 x 15 second images at ISO 5,000 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 December 27, 2016 from Weatherly, Pennsylvania.
