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.

Orion Through Light Cloud Cover

I’ve been trying to experiment on wide field views, at lower ISO, and longer exposures, but the weather has not been cooperating. This is a single 4-minute exposure of Orion, obscured by light cloud cover, I think it was still a nice effect.

Tech Specs: Canon 6D with Canon EF70-200mm f/2.8L USM lens mounted on an iOptron ZEQ25GT mount. Single 4-minute exposure, ISO 400, 70mm, f/2.8. Imaging was done on December 25, 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.

NGC 1535 Planetary Nebula in the Constellation Eridanus

Here is a beautiful planetary nebula cataloged as NGC 1535, it is found in the constellation Eridanus and is about magnitude 10.5. Distances vary to this object and range from 5500 to 7500 light-years. Even a 15-second exposure at ISO 5000 reveals a lot from this object. I particularly like the double ring/shell.

Tech Specs: This image is composed of 44 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 1514 – The Crystal Ball Nebula of Taurus

This planetary nebula is located right on the border of Taurus and Perseus. It is cataloged as NGC 1514 and is also known as the Crystal Ball Nebula. Even this 14-minute exposure shows a lot of details in the nebulosity. The magnitude, depending on the source, is listed at 10.9.

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 November 6, 2016 from Weatherly, Pennsylvania.
