| Object | NGC 3324 |
| Info |
This nebulosity field is situated in the southern constellation of Carina. It lies north west from the famous Eta Carina nebula and is probably part of this nebulous complex. Discovered by James Dunlop from Parramatta, NSW, Australia. The 7.7mag B- type star HD92206 illuminates the HII emissions along the dark nebulous ridge. |
| Date | 26th & 30th/ 1/ 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:20' L: 40' R:30' G:30' B:30'( 5min sub exposures) All images were unbinned, no dark frames removed. Sigma rejection combined. Luminance and Ha composites layered in PS and then combined as a HaL. RGB elements combined using Steve Canistra's corrected Luminance technique. Image has been reduced to 85%. |
| Guiding |
Orion 80ED refractor F7.5 with a Meade LPI imager. Mounted via a side by side accessory plate. Note: Lum and RGB's were auto guided. Ha was unguided @ 5min subs! |
| Filters | Astronomik Type II clear, RGB and 13Nm Ha |
| Notes/ Conditions |
This morning had very poor conditions. Smoke from recent bushfires in South Australia and in the state of Victoria was pushed into my far west coast area by strong south easterly winds. Auto guiding at F9 with luminance was proving to be a chore with the auto guider chasing the seeing. I GEM flipped and decided to do some Ha, however I lost my guide star so for an experiment decided to see how many unguided images I could keep. I took 5, 5min exposures, 1 of which I threw out. On the 30th when taking the RGB's the conditions were once again very poor. Wind gusts were severe coming from the sth east exactly where I had the dome open to. |
