| Object | NGC 3576 |
| Info |
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. |
| Date | 14th & 15th(Ha) 26& 27th (Lrgb)/ 2/ 06 |
| Location | BayTop Observatory- Streaky Bay South Australia |
| Instrument | Vixen VC200L working @ f9/ 1800 FL 0.77arcsec/pixel |
| Mount | Celestron CI700 controlled by a Mel Bartels Goto Control System with Vexta PK264m-01b motors with a pulley and belt system |
| Camera (CCD) | Starlight Xpress HX916 monochrome with Hm, made filter slider |
| 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. |
| Guiding |
Orion 80ED refractor F7.5 with a Meade LPI imager. Mounted via a side by side accessory plate. |
| Filters | Astronomik 13nM Ha & typeII clr rgb filters |
| 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. |
