flies high through the August night 24 00:03:03,470 --> 00:03:00,099 using bright Vega as your guide star 25 00:03:06,750 --> 00:03:03,480 look for the cross just to the east 26 00:03:11,250 --> 00:03:06,760 Cygnus is also known as the northern 27 00:03:15,199 --> 00:03:11,260 cross Albireo at the head of the Swan is 28 00:03:17,910 --> 00:03:15,209 a showpiece for small telescopes this 29 00:03:20,580 --> 00:03:17,920 spectacular pair of stars features 30 00:03:25,850 --> 00:03:20,590 contrasting colors of sapphire and 31 00:03:29,819 --> 00:03:25,860 golden topaz Deneb the Swans tail is a 32 00:03:32,789 --> 00:03:29,829 supergiant star if Deneb replaced the 33 00:03:36,650 --> 00:03:32,799 Sun in the center of our solar system it 34 00:03:40,650 --> 00:03:36,660 would engulf Mercury and Venus on a 35 00:03:43,530 --> 00:03:40,660 clear night hazy patches of nebulae can 36 00:03:48,630 --> 00:03:43,540 be seen by casually panning across the 37 00:03:51,660 --> 00:03:48,640 Cygnus area with binoculars the most 38 00:03:54,870 --> 00:03:51,670 prominent is the North America nebula an 39 00:04:03,500 --> 00:03:54,880 area of gas and dust illuminated by the 40 00:04:11,479 --> 00:04:06,899 cygnus also hosts several clusters of 41 00:04:16,680 --> 00:04:11,489 stars the easiest to find our m29 and 42 00:04:19,439 --> 00:04:16,690 m39 m29 is found near the center of the 43 00:04:23,810 --> 00:04:19,449 northern cross when viewed in a small 44 00:04:28,740 --> 00:04:23,820 telescope it resembles a small square 45 00:04:32,430 --> 00:04:28,750 best seen in binoculars m39 is a loosely 46 00:04:40,200 --> 00:04:32,440 bound cluster of about 30 stars just to 47 00:04:43,020 --> 00:04:40,210 the north of Deneb just south of Cygnus 48 00:04:46,740 --> 00:04:43,030 lies the small constellation vulpecula 49 00:04:50,219 --> 00:04:46,750 the little fox first charted by polish 50 00:04:57,840 --> 00:04:50,229 astronomer johannes hevelius in the 17th 51 00:05:00,390 --> 00:04:57,850 century vulpecula hosts the dumbbell 52 00:05:03,510 --> 00:05:00,400 nebula which can be seen as a faint 53 00:05:28,870 --> 00:05:03,520 smudge in binoculars a small telescope 54
