Some of the best known ones are the open star clusters Messier 36, Messier 37 and Messier 38, the Eskimo Nebula, the Christmas Tree Cluster, the Cone Nebula and the Rosette Nebula. But NGC 1532 is the real treat here. The core also appears irregular. Through a large scope, this galaxy’s nucleus has a slight east-west elongation, which puts it in the barred spiral category. Think the Perseids are the only shower worth watching? Prominent constellations that can be seen in October include Cetus, Pisces, Aries, Triangulum, and Andromeda. Through an 8-inch scope at 100x, you’ll count two dozen stars. Second, head to as dark a site as you can find because my list contains galaxies, and you won’t see those from a city. Many observers see this 20'-wide object before they spot IC 1805. Choose a unit that magnifies between 10 and 15 times. By signing up you may also receive reader surveys and occasional special offers. Constellation: Ursa Major. This book reveals, for each month of the year, the choicest celestial treasures within the reach of a commercial CCD camera. The Trifid Nebula, and the … This phenomenon is also variously known as “[the] ashen glow”, “[the] old Moon in the old Moon’s arms”, or [the] “Da Vinci glow”, after Leonardo Da Vinci, who was the first observer in recorded history to explain the science behind the phenomenon. Each requires at least an 8-inch telescope and a dark sky. Constellation: Aquila All told, more than 100 young stars brighter than magnitude 12 spread across the association’s 3° width. Many group into whirls and other patterns. Located about 47 million light-years away in the constellation Cetus, this magnitude 9.6 galaxy stretches across 170,000 light-years, which makes it one of the largest galaxies listed in the Messier catalogue. Through a small scope, NGC 925’s figure appears indistinct, but an 8-inch or larger instrument reveals the spiral arms that fold back abruptly from a long bar. Don’t confuse it with NGC 1272, a similar but slightly fainter galaxy just 5' to the west. The following Deep Sky Objects are found in constellations that peak during the month. This could make it difficult to obtain clear views of either planet without the aid of an atmospheric dispersion corrector. View our Privacy Policy. The Deep-Sky Observers Year is a month-by-month guide to the best objects to view. This is the best night of the month to observe the night sky, since light from stars and faint deep sky objects won't have to compete with bright moonlight. The head appears denser, while the body surrounds a small star cluster within. M45 (mag 1.3) is visible in the evening sky, becoming accessible around 17:12 (PST) as the dusk sky fades, 28° above your eastern horizon. Deep-sky objects AT2018cow , a large astronomical explosion detected on 16 June 2018. A 12-inch scope resolves about 20 more stars. The Orion StarBlast 4.5 Astro Reflector Telescope is … On my scope I don't consider there to be any one "best magnification" for deep sky observing. I really recommend beginners using a planisphere; it makes it so much easier finding constellations and objects. Through a 6-inch telescope, NGC 1535 has a sharply defined disk (18" across) surrounded by a faint envelope. It sits 3.4° east-southeast of Atik (Zeta [ζ] Persei). The galaxy spans 8.9' by 6.5'. Plan a family 'staycation' exploring the night sky, 40 years after Voyager, scientists push for new missions to Uranus and Neptune, Hibernating lemurs may be the key to cryogenic sleep for human space travel. Medium and large telescopes should reveal the planet in the constellation Aries, about ten or so degrees to the southward of the constellation’s brightest star, Hamal (alpha Arietis). As winter melts into spring, we sample both familiar and overlooked deep-sky treasures in the "empty space" between Gemini and Leo, home of the Crab. Through a 4-inch telescope, use 150x to spot 50 member stars spread across 18'. At the cluster’s southwest edge sits a magnitude 8.5 star. Observers refer to NGC 1554 as Struve’s Lost Nebula, and NGC 1555 is Hind’s Variable Nebula. A short version of the Top 10 Night Sky Objects can be download as PDF and printed. The brighter northern half’s lane enters from the east and is thin. Spend some time with this cluster at magnifications above 200x. Four cluster stars shine brighter than 8th magnitude, including double star ADS 2426 at the center. There sits globular cluster NGC 1049. Sharp-eyed observers may just detect NGC 1528 as a hazy star from a dark observing site. It spans 6'. Keep the magnification under 20x. However, while this shower is not expected to produce more than 5 to 10 meteors per hour, this Southern Taurids is known for producing particularly bright meteors, at least some of which should be visible although the Moon will be close to full during the peak period. – Object type: Open cluster. I’ll tell you my top 3 winter deep sky objects further down this post. It will then reach its highest point in the sky at 22:03, 66° above your southern horizon. Through an 8-inch telescope, you’ll see a 6' by 3' haze that’s brightest at the northeastern end, where a magnitude 10.5 star that illuminates the nebula resides. Located about 30 million light-years away in the constellation Pisces, this spectacular magnitude 10.0 galaxy, seen directly face-on, is a perfect example of a so-called “grand design” spiral galaxy. However, while the three showers listed below are not particularly productive, observers who have access to dark skies might see some bright meteors from the showers listed below, nevertheless-. This galaxy’s spiral arms wrap so tightly around its core that it appears elliptical through most telescopes. October 19 2020 Observation Report - posted in Deep Sky Observing: Hi, I want to share a wonderful observation session I had on October 19 2020. From a dark site, you’ll find the Spiral Cluster with your naked eyes roughly 5° west-northwest of Algol (Beta [β] Persei). View it through a 3-inch telescope at a magnification of 50x, however, and you’ll spot two dozen stars spread across an area 15' wide. This system measures 10.5' by 6.3'. Thought about this Edit for a while. Even fainter is magnitude 12.2 NGC 1035, 23' northeast of NGC 1042. – Jupiter / Saturn will continue their joint progression across the sky during October, until they will reach what is known as their “great conjunction” during the second half of December 2020. This odd group has a 9th-magnitude star at both its north and south end, a couple more 10th-magnitude stars, and about a dozen magnitude 12 and fainter stars. Move 6.9° west of magnitude 4.0 Beta Camelopardalis to find the Blue Oyster Nebula. That said, I’ve spotted this object through a 4-inch refractor using a wide-angle eyepiece. Meanwhile, Cassiopeia and the Milky Way are both nearly directly overhead, with the Milky Way stretching across the sky from east to west. Before you start, let me offer three tips. The object. For the best conditions to see galaxies, nebulas, and other deep sky objects, plan a stargazing session for the night of October 16th, when the New Moon will provide dark skies. This will make it visible as an early morning object for about three hours or so before dawn. Use the autumn constellation patterns to locate the Andromeda Galaxy and other deep-sky objects. – Venus starts the month rising at about 02:00 (BST), but rises progressively later until at month’s end, it will rise at about 04:00 (BST). In it he explored the dim denizens of the deep sky — asterisms, double and variable stars, open and globular clusters, nebulae, and galaxies. It’s tiny (1'), so use a big scope. Through a 4-inch telescope, you’ll see about 20 stars spanning 12'. The other arm, only slightly fainter, appears somewhat blotchy, revealing huge star-forming regions within it. You’re looking for a faint haze just brighter than the background sky. Use a magnification around 100x to catch all three galaxies at once. [12] [13] As of 22 June 2018, this astronomical event has generated a very large amount of interest among astronomers throughout the world [14] and may be, as of 22 June 2018, considered a supernova tentatively named Supernova 2018cow . First, dress warmly, because observing involves just sitting (or standing) and looking. Through a 16-inch scope, an arm that radiates to the north of the core and turns abruptly to the west is quite prominent. Plus, get FREE SHIPPING & BONUS GIFT! Only 15' to the southwest lies the magnitude 11.0 spiral NGC 1042. This galaxy appears small and nearly circular (3.2' by 2.3'). The nights are getting longer, the air clearer, and those pesky summer mosquitoes are a thing of the past. Find this pair 1.5° northwest of Upsilon4 Eridani. Find astronomy targets and generate object lists for your observing and astrophotography sessions. Note also that due to it approaching opposition, Mars will be visible throughout the night during October, but at about 03:00 (BST) on the 3rd, the planet will be within one degree above the (nearly) Full Moon. Note that Venus will remain a bright pre-dawn object for the remainder of 2020. It’s time to decide which Deep-sky object you’re going to image. You’ll find this mix of emission and reflection nebulosity 3.3° west-southwest of Omicron (ο) Persei. I'll concentrate on objects in Sagittarius, Cygnus, Vulpecula and Lyra that are well placed for observing during the two hours beginning at astronomical dark. Don’t expect to see an object that even approaches the cataloged size of 25'. NOTE: Other meteor showers during October include-. A magnitude 7.0 star glows at the heart of NGC 1027. 0. … Infinity & Beyond — Episode 9: Saturn's rings, Infinity & Beyond — Episode 8: Black holes 101.
