As with M37 and M38, it has a bright central star&#8211;orange in color. Some yellow and blue stars to the north and east spiced up the color a bit. To the west-southwest, a soft, unresolved glow indicated a more distant cluster (NGC 2158) which made a nice counterpoint to the wide open stars on the left half of the view. M35&#8217;s shape is roughly circular and not condensed, with its brighter stars scattered evenly. Its diameter appears to be 28&#8242; across (which matches exactly the dimension listed by SEDS&#8211;Wahoo!). NGC 2158 is roughly 8&#8242; in diameter, with a soft glow that doesn&#8217;t appear to have a central condensation&#8211;just a soft fade at the edges.<\/p>\n<p>[Edit Jan 6, 2010: Cleaned up and re-framed the digital version of sketch. The original version of the sketch can be found here: <a href=\"http:\/\/www.perezmedia.net\/beltofvenus\/archives\/images\/2005\/img2005020303_M35.jpg\">2005 version of M35 sketch<\/a>.]<\/p>\n<p><b>Object Information:<\/b><\/p>\n<p>M35 consists of 400-500 stars with 120 brighter than magnitude 13. It is 2700 to 2800 light years distant with a diameter of about 24 light years. It is estimated to be about 100 million years old and contains several yellow and orange giants. The cluster is approaching us at 5 km\/sec. It was discovered by Philippe Loys de Ch\u00e9seaux in 1745-46, independently rediscovered by John Bevis before 1750, and catalogued by Charles Messier in 1764 (Messier acknowledges Bevis&#8217; discovery).<\/p>\n<p>NGC 2158 is situated 15&#8242; southwest of M35, glows at magnitude 8.6 and has a diameter of 5&#8242; (compared to my estimate of 8&#8242;). It is much more compact than M35, ten times older and 5 times more distant. With an age of over 1 billion years it contains many yellow stars. It was once thought to be a candidate for a globular cluster. It was discovered by William Herschel.<\/p>\n<table width=\"470\" border=\"1\" cellspacing=\"0\" cellpadding-left=\"4\">\n<tbody>\n<tr>\n<td><b>Subject<\/b><\/td>\n<td>M35 (NGC 2168) and NGC
