Constellation: Ursa Major. One of the finest naked-eye objects also ranks as the sky’s brightest star cluster (magnitude 1.2). Double that aperture to 12 inches, and you’ll begin to pick up this object’s color. – The Orionids Meteor Shower is expected to peak on the night of the 21st/22nd, during which up to about 20 meteors per hour may be visible. Use a magnification around 100x to catch all three galaxies at once. You’ll find this nice open cluster not quite 6° east-southeast of Epsilon Cassiopeiae. NGC 1232 isn’t quite round. 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. 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. It spans 6'. The winter deep-sky targets in the Orion constellation are arguably the best of the Northern Hemisphere. In it he explored the dim denizens of the deep sky — asterisms, double and variable stars, open and globular clusters, nebulae, and galaxies. Bright knots intermingle with the gas on the northwestern and southeastern sides. From Chi2, which is the brightest, move 1.3° east-southeast. With my recent addition of a modified Canon T3i and 12nm ha filter, I am anxious to capture these nebulae in a new way. The exception is the 5th-magnitude sparkler SAO 12969 that sits in the center. Despite this though, Pierre Méchain, who discovered it, described M77 as a nebula, while William Herschel described it as a star cluster. On my scope I don't consider there to be any one "best magnification" for deep sky observing. October 1, 2020 … I’ll tell you my top 3 winter deep sky objects further down this post. Plus, get FREE SHIPPING & BONUS GIFT! Through an 8-inch telescope, you’ll see NGC 1097’s core as a bright disk surrounded by an oval haze. Find astronomy targets and generate object lists for your observing and astrophotography sessions. Lying 2.8" away, however, the magnitude 7.3 companion should not appear the shade of blue most observers report. This magnitude 6.4 open cluster lies 1.6° east-northeast of Lambda Persei. 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. MARKARIAN'S CHAIN - THE VIRGO CLUSTER. 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. Our next object is a magnitude 9.2 barred spiral that sits 2° north of Beta Fornacis. This attractive, nearly face-on barred spiral galaxy glows at magnitude 10.1 and measures 12.0' by 7.4'. Choose a unit that magnifies between 10 and 15 times. You won’t see much of the thin spiral arms no matter what scope you observe through. And I list them in order of right ascension, so if you start observing selections at the top of the list, subsequent objects will rise higher as the night goes on. Observers refer to NGC 1554 as Struve’s Lost Nebula, and NGC 1555 is Hind’s Variable Nebula. A 16-inch scope reveals striations that extend away from the southern tip. For an overall view, insert a nebula filter and identify the Heart’s brightest regions: the central cluster, the knot of nebulosity to the east, and the crescent of gas to the southwest. If you still have trouble spotting the nebula, try increasing the magnification to 150x or beyond. There sits globular cluster NGC 1049. – 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). Moreover, since the little planet reaches a point of inferior conjunction on the 25th of the month, it will reappear as an early morning object after this date. Hind’s Variable Nebula appears as a faint wisp of nebulosity near T Tauri. These three objects are all simple to locate in the summer sky, between July and September. Receive news, sky-event information, observing tips, and At magnitude 1.2, this large, scattered group of stars is obvious to the naked eye. Although October sees the peaks of seven meteor showers, only three are worth staying up for. At the cluster’s southwest edge sits a magnitude 8.5 star. Remove the filter, and your mind will fool you into thinking the reflection nebulosity has gotten brighter. Observers that feel up to the challenge of locating and observing M74 should be able to find it 1.5 degrees to the east-northeast of the star Eta Piscium, the brightest star in Pisces. Use the autumn constellation patterns to locate the Andromeda Galaxy and other deep-sky objects. THE TRIFID NEBULA (M20) Magnitude: 6.3. The galaxy spans 8.9' by 6.5'. The Cascade is 15 stars that stretch 2.5°. Through even a 4-inch telescope at a dark site, you’ll see NGC 1365’s bar and brighter central region. 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. The western section is slightly brighter. We do not sell, rent or trade our email lists. Look for it as a faint, fuzzy star with your naked eyes. NOTE: October has a Blue Moon, or second Full Moon, which occurs on the last day of the month. Through a 16-inch scope, an arm that radiates to the north of the core and turns abruptly to the west is quite prominent. Look through either a Hydrogen-beta or deep-sky nebula filter. Although equally as wide (1°) as the Heart, the Baby doesn’t cover as much area, so it appears more concentrated. This system measures 10.5' by 6.3'. This galaxy appears small and nearly circular (3.2' by 2.3'). 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 magnitude 3.5 primary appears white or “just a bit” yellow. Star clusters (like the Pleiades and Hyades), are also included. This will make it visible as an early morning object for about three hours or so before dawn. Infinity & Beyond — Episode 9: Saturn's rings, Infinity & Beyond — Episode 8: Black holes 101. 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. Find this pair 1.5° northwest of Upsilon4 Eridani. Don’t expect to see an object that even approaches the cataloged size of 25'. Thought about this Edit for a while. Through a 6-inch telescope, it appears twice as long as wide (7.3' by 3.3') and aligned nearly east-west. To find it, point your telescope 2° east of Gamma (γ) Trianguli. Order now to get your Black Holes Collection from Space & Beyond Box! 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. Deep-sky observing is easily the most popular field for amateur astronomers. The Pinwheel … The powerful radio source Fornax A is a bright (magnitude 8.9) spiral galaxy you can find 1.4° south-southwest of Chi1 (χ1) Fornacis. Stitching together images of adjacent parts of the object to create a mosaic lets you capture these extended objects. A magnitude 7.0 star glows at the heart of NGC 1027. Often called the Seven Sisters, most people see only six stars. Nonetheless, at about 03:00 (BST) on the morning of the 14th, Venus will be separated from the waning crescent Moon by about 3 degrees, just north of east, which should make for an interesting sight in binoculars. If you can’t split it at 50x, just double the power, and you’ll have no problem. Hey guys!! This book reveals, for each month of the year, the choicest celestial treasures within the reach of a commercial CCD camera. An 8-inch scope shows the spiral arms. NGC 1316 is about half again as long as it is wide (11' by 7.6'), and it orients northeast to southwest. By contrast, the dark region in the southern half of NGC 1360 is wide, extending all the way from the southern tip to the 11th-magnitude central star. June 2010: By Dave Huestis This month Dave Huestis examines the 5th largest constellation in the sky - Hercules. Use a 14-inch or larger scope, however, and you’ll see that the central region spans half of this galaxy’s overall length. The list provides basic information about each object: magnitude, number of stars, page in Uranometria 2000, comments, common name, etc. As a further point of interest, this phenomenon also occurs on the moons of other planets in the solar system, in which case it is known as “planet shine”. Many group into whirls and other patterns. Through an 8-inch telescope at 100x, you’ll see the brightest 15 or so members in front of a haze of fainter stars. Although the Fornax Dwarf Galaxy’s stated magnitude is 8.1, its size (12' by 10.2') makes its surface brightness low. 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.
