Object  NGC 3576

This is only a partial/ close up image of NGC3567 nebulae's extent. (upper loops are not pictured here). It is situated in the southern constellation of Carina, located in a very star rich area of the southern Milkyway. It is amongst the largest HII (ionized hydrogen) regions in the Galaxy, containing large numbers of hot, young, massive stars. NGC 3576 has many  HII regions which are ideal areas for studying star formation over a broad mass scale in a number of wavelength bands.  This region is partially obscured by foreground dust in the Galaxy, and possess a considerable amount of internal dust, as seen. It lies at a distance of about 3000 pc, or 9800 light years.

Exposures HA:195' L:80'  R:40' G:40' B:40' ( 5min sub exposures)  All images were unbinned, no dark frames removed. Ha Median combined. Lum & RGB's sigma combined. Lum combined to Ha to produce a HaLum composite then combined to the RGB composite in Photoshop using Steve Canistra's Luminance corrected technique. Image has been reduced to 85% for better viewing.

Notes/ Conditions

 Conditions were steady on the 14th, but transparency was very average. Conditions on the 15th were not as steady and transparency was similar to the night before.  Conditions when taking the rgb's and luminance was very similar to the above.
