NGC 1087 NGC 1090 in Cetus



Scope: C8 f/5.6; Location: Laguna Mountains, CA;  29 September 2008; Camera: Artemis285

Exposure: 8 x 8 min Luminance exposure (bin 1x1) with Baader IR Block Filter; 6 x 3 min RGB (bin 2x2)

Processing: Images were captured Artemis Capture (as FITs). Aligned/stacked and dark subtracted in Astroart with Sigma Combine. Luminance and Color channels were scaled and rough color balanced in Astroart.  Central Gradient was removed on all channels in Astroart. Channels were co-registered in Astroart. The 8 minute IR block exposures were used for the main luminance construction with level adjustments and curves to bring out object features.   LRGB combine was done in Photoshop. G2V  factors applied to color channels.  Final Image size is approximately 1392x1040.

This image was guided; North is up.  NGC 1087 is the galaxy in the lower right. NGC 1090 is the galaxy in the upper part of the image. Both are in the optical vicinity of M77 but not associated with M77 as a grouping - they are background galaxies at a further distance. NGC 1087 is estimated 66 million light years distant from Earth.; NGC 1090 is estimated at 122 million light years distant. The next most prominent galaxy (NGC 1094) in this field is near the left edge. There are several other smaller galaxies throughout this field. Horizontal FOV is 27'

Image Center is approximately - Equatorial 2000: 02h 46m 53s Dec: -0021'38"
