NGC891

Image Information

Quoted From SEDS
Explanation:

Discovered by William Herschel in 1784.

NGC 891 is a fine edge-on spiral with a faint dust lane along its equator. It was discovered by William Herschel on October 6, 1784, and cataloged as H V.19. However, in the appendix to his first catalog, he confused it with his H V.18 (M110, NGC 205) when discussing the discoveries of his siter Caroline Herschel; this remark was picked up by Admiral Smyth and later authors so that it was wrongly attributed to Caroline for a long time.

  • NGC 891 is a member of a small group of galaxies, sometimes called the NGC 1023 group, which also contains NGCs 925, 949, 959, 1003, 1023, and 1058 as well as UGCs 1807, 1865 (DDO 19), 2014 (DDO 22), 2023 (DDO 25), 2034 (DDO 24), and 2259.

    Supernova 1986J was discovered in NGC 891 by van Gorkom, Rupen, Knapp, Gunn on August 21, 1986 and reached mag 14 (see IAUC 4248).

    NGC 891 is contained in the SAC 110 best NGC object list. It is also Caldwell 23 in Patrick Moore's List. In the RASC's Finest N.G.C. Objects Objects list.

     

  • Edge-on spiral galaxy NGC 891 was featured in Jeff Bondono's Masterpieces Messier Missed for December, 1995

    This image is compiled from 9 - 15 minute Luminance images.  RGB data is 11 each for 15 minutes each for a total of 10 hours of data used. All data was acquired ACP Web Interface using MaxImDl/CCD version 4.56. Images were reduced and saved in MaxIm. The data was then brought into CCDStack where bloom removal, alignment, and sigma reject was performed to produce the master image. Photoshop CS 2 was used for curves and levels.  The image data was collected over November 17-20, 2006.
