Eta Carina Nebula
An image of the Eta Carina Nebula taken by Bob Winter at ‘Space Ops’ in the Atacama desert in northern Chile, while on an eclipse tour to Easter Island.
Eta Carina is a massive star (100x Solar Masses), emitting dust and gas, and will be a Supernova at some point.
Image Data:
Pentax 75 APO refractor.
QSI 583 Astro camera, LRBG image using L, Ha, Olll, Hb.
33 files at 30secs each, total 16.5 min. Calibrated bias and dark.
Unguided.
Short exposures had to be used as there was star trailing at longer ones due to the great difficulty of polar alignment in the S Hemisphere. In fact the whole thing was very demanding!
