NGC-1275-Re-Do
Image Information
Quoted from SEDS:
From SEDS.org
NGC 1275 was one of William Herschel's discoveries; he found it on
October 17, 1786. John Herschel included it in the GC from observations
of d'Arrest and apparently never observed it himself.
It is the dominant member of the Perseus Cluster of Galaxies and a
strong radio source, therefore named Perseus A, and 3C 84 from its entry
in the 3rd Cambridge Catalogue of Radio Sources. It is also a strong
X-ray source. Its nucleus shows emission lines and is of Seyfert type 1
- this galaxy was in Carl Seyfert's original list of galaxies with
peculiar emission lines in their nucleus, now called
Seyfert galaxies. Filaments of gaseous material are moving
explosively outward at 1500 miles per second.
Supernova 1968A was discovered in NGC 1275 on January 25, 1968 by
Lovas 7"E and 24"S of the galaxy's nucleus and reached mag 15.5 (IAUC
2051).

There are 17/15/16 RGB - 20 minute and 22 -
20 minute luminance images
used in this LRGB image. A total of 23-1/3 hours
of data was used for this image. All data was
acquired using MaxImDl/CCD version 5.15 using ACP. Images
were reduced and saved in MaxImDl version 5.
Alignment, average combining, along with histogram stretching,
deconvolution, and HDRWavelets was done using Pix Insight. Two new
tools in Pix Insight, HDRMultiscaleTransform and
MultiScaleMedianTransform, were used to greatly reduce noise and bring
out the faint detail in NGC-1275. Photoshop CS 5 was used to create the JPG versions for web presentation.
The image data was collected between October 29 - Nov. 2, 2011 using ACP
version 6.2.
