M35  

M35, in the constellation of Gemini, was first described by Philippe Loys de Chéseaux in 1745 and independently by John Bevis in1750.  Charles Messier included it in his catalogue on 30th August 1764 and credited discovery to John Bevis.  It is 2,800 light-years away and is about 24 light-years across.  At its centre the density of stars is estimated at 6.2 stars per cubic parsec.  It is estimated to be 100 million yeaars old and is approaching us at 5 km/sec.

	M35 captured with 58 mm SLR lens.  The field of view is about 4.8×3.6 degrees, but the diameter of the cluster is only about 28 minutes of arc.  The cluster as a whole has a visual magnitude of 5.3 so it should ve visible to the naked eye in a totaly dark sky. Date and Time: 10th February 2008 22.34 UT Camera: Atik 16ic colour Telescope: 58 mm SLR lens at f/4 Capture: ArtemisCapture. Exposure 60 sec. Processing: K3CCDTools. 106 frames stacked, histogram 15-255, unsharp mask 3,0,100
	This is a much closer and more detailed view of M35, captured with a DSLR and Ritchey-Chrétien telescope.  The field of view is about 47×32 arc minutes (about the size of the full Moon). Date and Time: 26th February 2019 21.33 UT Camera: Canon 600D Telescope: 8-inch Ritchey-Chrétien Capture: EOS. Exposure 30 sec. Processing: Registax 5. 10 frames stacked           Focus Magic 4.
