NGC 1365 in Fornax



Scope: C8 f/6.7; Location: Blair Valley, Anza Borrego Desert, CA;  20 December 2008; Camera: Artemis285

Exposure: 12 x 5 min Luminance exposure (bin 2x2) with Baader IR Block Filter; 7 x 3 min RGB (bin 3x3)

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 5 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. Background noise reduction was applied (selective Median filter) in Photoshop.  Selective sharpening was applied to galaxy features. Final Image size is approximately 1392x1040.

This image was guided; North is up.  NGC 1365 is a fine example of a barred spiral galaxy. It is located in the constellation of Fornax. The "bar" appears golden yellow with prominent dust lanes. The bar ends with the graceful blue spiral arms extending outward. NGC 1365 is about 60 million light years distant from Earth. Horizontal FOV is 23'

Image Center is approximately - Equatorial 2000: RA: 03h 33m 36s Dec: -3608'17""
