The Pinwheel … Stitching together images of adjacent parts of the object to create a mosaic lets you capture these extended objects. The exception is the 5th-magnitude sparkler SAO 12969 that sits in the center. Earthshine occurs when sunlight is reflected off the surface of the earth, and onto the part of the surface of the Moon that is not illuminated by direct sunlight. Collectively, these constellations contain a variety of spectacular deep-sky objects, examples of which we will cover later on this guide to October’s night sky. Designation: M101. Before you start, let me offer three tips. A magnitude 8.0 star sits slightly southeast of the cluster’s center. Magnitude 9.4 NGC 1360, however, appears twice as long as it is wide, extended in a roughly north-south orientation. Look for this galaxy about 0.7 degrees to the east-southeast of the fourth magnitude star Delta Ceti, and decide for yourself if the object resembles a nebula, a star cluster, or a galaxy. In a few months, Orion and his magnificent wintry retinue will take center stage. A 12-inch scope shows lines and arcs of the brighter members and brings 50 more stars into view. Through a 12-inch telescope at a magnification above 200x, both sections have a darker lane crossing them. Many group into whirls and other patterns. Can you see three? The list provides basic information about each object: magnitude, number of stars, page in Uranometria 2000, comments, common name, etc. It will continue to be observable until around 04:39, when it sinks below 12° above your western horizon. George and Laura Mishler/Adam Block/NOAO/AURA/NSF. Best for Combining Photography & Astrophotography: Canon EF 300mm f/4L IS USM William Herschel discovered that Polaris was binary in 1780. Sharp-eyed observers may just detect NGC 1528 as a hazy star from a dark observing site. The magnitude 9.3 spiral galaxy (known as the Perseus Lenticular) measures more than twice as long as it is wide (8.6' by 4.2'), stretching in a rough east-west direction. Through the eyepiece it scarcely spans 4'. Many observers see this 20'-wide object before they spot IC 1805. The image above shows an instance of Earthshine, which phenomenon can be observed this October during the waning crescent Moon phase from the 11th to the 16th, and again from the 17th to the 22nd during the waxing crescent Moon phase. Collectively,  these constellations contain a variety of spectacular deep-sky objects, examples of which we will cover later on this guide to October’s night sky. The core also appears irregular. 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). The Crystal Ball Nebula is a round, magnitude 10.9 hazy planetary that spans 114". Order now to get your Black Holes Collection from Space & Beyond Box! Constellation: Sagittarius. – Mars will be the brightest it will ever be until September of the year 2035. At the southeast end of Kemble’s Cascade, in the same field of view, sits the tight open cluster NGC 1502 (7' across). Through an 8-inch telescope at 150x, you’ll spot 50 stars evenly distributed across its 11.0' by 7.6' face. To find it, look 5.6° northeast of Alpha Fornacis. With magnifications of 200x or more, the brilliant core appears surrounded by an oblong haze. From there, move 5' northeast, and you’ll encounter the variable star T Tauri, which usually shines at magnitude 9.6. The object. Although the yellow magnitude 2.0 primary outshines the blue magnitude 9.0 secondary by more than 600 times, the separation is a worthy 18.3", so a 3-inch telescope at 100x easily will show you Polaris B. Located about 130,000 light-years away from the core of the Andromeda Galaxy‘s core, Mayall 11 is the biggest and most massive globular star cluster in the entire Local Group of galaxies. Keep the magnification under 20x. You won’t see much of the thin spiral arms no matter what scope you observe through. You’ll need a telescope to see its individual stars, but you won’t miss its overall magnitude 5.7 glow. At magnitude 11.9, spiral galaxy NGC 1275 is the brightest member of the Perseus galaxy cluster (Abell 426). Since it is at least twice as massive as Omega Centauri (the Milky Way‘s most massive globular star cluster) most investigators believe that Mayall II is not a true globular cluster, but rather that it is the remains of a small dwarf galaxy that had been destroyed by the Andromeda Galaxy in the distant past. Used my heavy gun - NMT 20F/3.3, my Galaxy hunting scope and the only one I use on dark locations. Thought about this Edit for a while. When you switch to a telescope, select your eyepiece that provides the lowest magnification. Of course, you’ll also be able to spot them several months before and after this month. – Uranus will come into opposition with the Sun on the last day of October, and should therefore be visible during the hours of darkness for all of October. Another bright nebulous knot, NGC 896, lies 1° southwest of the Heart. 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. To see the stars better, remove the nebula filter. The Deep-Sky Observers Year is a month-by-month guide to the best objects to view. You’ll find this nice open cluster not quite 6° east-southeast of Epsilon Cassiopeiae. Although M45 is a great target to just look at, it’s terrific through binoculars. Through a 6-inch telescope, it appears twice as long as wide (7.3' by 3.3') and aligned nearly east-west. It will then reach its highest point in the sky at 22:03, 66° above your southern horizon. Dozens of foreground stars populate the field, adding a third dimension to the view. Double that aperture to 12 inches, and you’ll begin to pick up this object’s color. Through a 6-inch telescope, NGC 1535 has a sharply defined disk (18" across) surrounded by a faint envelope. It spans 6'. It’s the Pleiades (M45). I really recommend beginners using a planisphere; it makes it so much easier finding constellations and objects. Look 39' east of Delta (δ) Ceti, and you’ll find this magnitude 10.6 spiral galaxy. This object shines at magnitude 12.6 and measures roughly 1.2' across. Despite this though, Pierre Méchain, who discovered it, described M77 as a nebula, while William Herschel described it as a star cluster. Set aside some time under a moonless sky to view this wide variety of celestial treats. This book reveals, for each month of the year, the choicest celestial treasures within the reach of a commercial CCD camera. To find it, look 2° east of Algol. But NGC 1532 is the real treat here. This galaxy glows at magnitude 11.9. However, this only becomes an issue with the largest deep-sky objects. Plus, get FREE SHIPPING & BONUS GIFT! Prominent constellations that can be seen in October include Cetus, Pisces, Aries, Triangulum, and Andromeda. The magnitude 14 central star is easier to see than its brightness suggests. Even though summers are associated with shorter … This magnitude 8.9 open cluster lies 5.7° west-southwest of Epsilon Persei. The best example of a barred spiral — NGC 1365 — languishes in Fornax, more than one-third the way from the celestial equator to the South Celestial Pole. It all depends on your seeing. View our Privacy Policy. We do not sell, rent or trade our email lists. Note that Venus will remain a bright pre-dawn object for the remainder of 2020. Four cluster stars shine brighter than 8th magnitude, including double star ADS 2426 at the center. Links to constellation maps are offered for all stars and deep sky objects. 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. Constellation: Aquila The June sky is well placed to reveal a variety of deep sky objects, including the Whirlpool Galaxy and the Ring Nebula. Helpful hints and advice on framing, exposures, and filters are included. This galaxy is three times as long as it is wide, but doesn’t show details through most scopes. [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 . Although you can spot M77, which glows at magnitude 8.9 and measures 8.2' by 7.3', through any telescope, an 11-inch or larger instrument and a magnification above 300x will let it put on a show. Use a magnification around 100x to catch all three galaxies at once. Good luck! 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. Through an 8-inch scope at 100x, you’ll count two dozen stars. Tonight's Sky's mission is to provide an online tool for amateur astronomers to plan their observing sessions. The Star of Bethlehem: Can science explain what it really was? The planetary’s face also appears patchy, with several small dark areas visible. The magnitude 3.5 primary appears white or “just a bit” yellow. * For southern latitudes, flip the season listed. Deep-sky objects AT2018cow , a large astronomical explosion detected on 16 June 2018. It combines the magnificent edge-on spiral NGC 1532 (magnitude 9.9) with elliptical NGC 1531 (magnitude 11.7), which sits less than 2' to the northwest. Seeing — the steadiness of the air above your observing site — is the key to discerning the individual spiral arms. This magnitude 8.9 open cluster lies 5.7° east-northeast of Almach (Gamma Andromedae). NGC 1316 is about half again as long as it is wide (11' by 7.6'), and it orients northeast to southwest. A 12-inch scope resolves about 20 more stars. Through an 8-inch telescope at 100x, you’ll see the brightest 15 or so members in front of a haze of fainter stars. Peter Christoforou Look for Mars in the constellation Pisces, about 7 degrees from the fourth-magnitude star Alrisha (alpha Piscium). 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. List includes all Messier, Herschel, Caldwell, SAC's best of NGC, and ~150 additional DSOs. This object is brighter along its rim. This shower is produced by debris left by the comet Halley. Constellation: Ursa Major. Through your finder scope, Stock 23 is an unresolved clump of stars. This attractive, nearly face-on barred spiral galaxy glows at magnitude 10.1 and measures 12.0' by 7.4'. Only 15' to the southwest lies the magnitude 11.0 spiral NGC 1042. One of the finest naked-eye objects also ranks as the sky’s brightest star cluster (magnitude 1.2). In October, these spectacular deep-sky objects, viewed through a reasonable sized telescope, can be observed in the constellations of Cetus, Pisces, and Andromeda. It’s a spectral class F star, which is hotter, and therefore should be just a bit whiter, than our Sun. To find it, point your telescope 2° east of Gamma (γ) Trianguli. These three objects are all simple to locate in the summer sky, between July and September. Meanwhile, Cassiopeia and the Milky Way are both nearly directly overhead, with the Milky Way stretching across the sky from east to west. Remove the filter, and your mind will fool you into thinking the reflection nebulosity has gotten brighter. The Best Deep Sky Objects for Summer. – Object type: Open cluster. 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. – Mercury reaches its point of greatest elongation on the first day of the month, but although it is located 26 degrees east of the Sun on this date, it sets very shortly after the Sun, which makes the planet visible for only a few minutes low on the horizon, at best. While the autumn night sky appears devoid of bright stars, it’s still home to a rich array of double stars. It glows at magnitude 6.7 and spans 15'. 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. The Trifid Nebula, and the … NOTE: Other meteor showers during October include-. The Orion StarBlast 4.5 Astro Reflector Telescope is … Note though that it may be difficult to discern the planet’s blue-ish tinge, given that it will be no brighter than magnitude +7.8. This small-telescope target is also known as Stock 23. On my scope I don't consider there to be any one "best magnification" for deep sky observing. 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. A fainter arm extends due east and ends near a 15th-magnitude star. Adam Block/Mount Lemmon SkyCenter/University of Arizona. Because most of our readers live north of the equator, I didn’t select any targets in the far-southern sky. From Chi2, which is the brightest, move 1.3° east-southeast. Although October sees the peaks of seven meteor showers, only three are worth staying up for. It inclines only 1.4° to our line of sight, glows at magnitude 9.9, and measures 13.0' by 2.8'. Hind’s Variable Nebula appears as a faint wisp of nebulosity near T Tauri. The following Deep Sky Objects are found in constellations that peak during the month. A 16-inch scope reveals striations that extend away from the southern tip. The core is quite a bit brighter, and ghostly hints of spiral structure appear at high magnifications. A magnification of 15x works best for framing the starry chain. This will make it visible as an early morning object for about three hours or so before dawn. Deep-sky observing is easily the most popular field for amateur astronomers. Use a 14-inch or larger scope, however, and you’ll see that the central region spans half of this galaxy’s overall length. … An OIII filter will dim it.
