About this image

One of the three Messier objects that are not discrete objects, the Small Sagittarius Star Cloud was discovered by Charles Messier in June 1764. 

This image, taken by the remotely operated Galaxy telescope at the Observatorio del Teide, Tenerife, makes it a little difficult for anyone unfamiliar with the star cloud (yes, that means me) to get their bearings. But it seems to show some areas of dark nebulae (Barnard 92, left, Barnard 93, right) and an open cluster (Collinder 469) to lower left.

I am enjoying playing with this telescope, courtesy of the OU's Open Learn course 'Astronomy with an online telescope'. Fascinating to be able to see further into the southern part of the sky and select objects for imaging while remaining at my desk here in Cheshire, UK.

Distance c.10,000ly. Age c.220million years.
