This image was taken on Dec. 25 in Tucson and consists of a stack of 30 4-minute exposures. The Crab Nebula is a supernova remnant and is located in the constellation Taurus and is 6,200 ly from Earth. It was first observed by Chinese astronomers in 1054 A.D. I posted an image of M1 in an earlier post - Dec. 2090 - one of the first images I took but didn't have enough exposure time to reveal its detail.
The above eclipse sequence was shot last night in Tucson between 11:20 pm and 12:50 am. Each image is a single shot: the first four with an exposure time of 0.01 sec. and the last with 6 sec. Unfortunately there were clouds and the moon was slipping in and out of the cloud cover. The first image was taken just prior to the Moon entering the Earth's shadow; in the last image the Moon is fully within the shadow. It wasn't a perfect night for imaging but the progression of the eclipse is clear.
This image was taken on December 13 in Tucson and consists of 20 4-minute exposures. NGC 1893 is the open cluster in the middle of the image. It is embedded in IC 410 which is a emission nebula. They are located in the constellation Auriga, near the Flaming Star Nebula (IC 405).
This image was taken in Abbotsford in October and consists of 44 4 minute exposures. The Triangulum Galaxy is located in Trangulum constellation and is about 2.8 million ly away. It is the third largest galaxy in the Local Group after the nearby Andromeda Galaxy and our own Milky Way. It was catalogued by Charles Messier in 1764.
This image was taken in Abbotsford during September. It consists of 20 4-minute exposures. The Pleiades (aka The Seven Sisters) is an open cluster located in the constellation Taurus. The main stars are visible to the naked eye.
The Flaming Star nebula is an emission nebula located in the constellation Auriga. The image consists of 53 4-minute exposures taken in Tucson on Dec 1, 9, 12. It is located about 1,500 ly away and is about 5 ly across.
