Hello,
Here is an image of Terzan 9, one of the 11 Globular Clusters discovered in 1968 by Agop Terzan in France whilst doing infrared work. Although I didn’t consciously set out to record the entire set of these esoteric GC’s, I have ended up with 3 of them; Terzan’s 11, 10 and 9. Weather and enthusiasm permitting, I might continue until I grab the complete collection, provided of course, that Gerald continues to extend the loan of his SBIG ST2000 and CFW10!
Imaging these faint objects via a series of quick raids into Sagittarius and Scorpius has kept me ticking over during a somewhat unproductive 2010, mainly due to unfavourable weather in Brisbane and my somewhat erratic enthusiasm. This image of Terzan 9 was captured beneath some quite soft, hazy skies which eventually turned into fog hence the clarity has suffered.
