Here, I list the highlights of some of my favorite atlases.
Key element number 1: All of them are great. All things considered, which one is best for you? That relies upon your experience, your objectives, and your telescope.
In case you’re simply beginning your experience into space science, pick an atlas that shows the stars you can see without an optical guide. Such atlases show stars to about magnitude 6.
Apprentice atlases likewise demonstrate a wide swath of sky on each page and may incorporate constellation diagrams.
These atlases additionally limit the quantity of plotted profound sky objects to just those unmistakable through a 4-inch telescope.
That rundown incorporates the 109 Messier objects, chosen objects from the New General Catalog (NGC), and the most splendid and most vivid double and variable stars.
Beginner’s atlases.
The Edmund mag 6 star atlas check on Amazon here.
My first pick is certifiably not a regular star atlas. All things considered, for four decades, the Abrams Planetarium Sky Calendar has advanced the cause of fundamental skywatching.
As its name suggests, the sheet for every month appears as a schedule. Charts track the Moon’s movement past the planets and splendid stars alongside remarkable groupings of sky objects.
The Sky Calendar is an incredible reference for beginner and intermediate space experts alike.
The other side of the sheet demonstrates the month’s mid-night sky for scope 40° north, which makes it valuable anyplace in the mainland United States.
And keeping in mind that the greater part of the star atlases in this story contain a large number of stars, the Sky Calendar demonstrates just the most brilliant 400 or so, contingent upon the month.
That number functions admirably for novices or for the individuals who see under moderate light contamination.
Abrams Planetarium distributes the Sky Calendar in free leaf structure and sends it quarterly (3 months for every mailing).
The Mag 6 Star Atlas distributed by Edmund Scientific Company of Barrington, New Jersey, first showed up in 1982. This 66-page work contains 12 graphs, each with a file of objects. You can find it here on Amazon.
Generally speaking, the atlas contains around 7,000 stars to magnitude 6.2, the independent human eye’s estimated point of confinement from a dull site. The atlas likewise plots almost 1,000 double stars, variable stars, and profound sky objects.
Swarmed locales in Orion, Virgo, and Sagittarius have point by point close-up diagrams that make it simpler to disclose to one object from another.
The most seasoned atlas on my rundown is Norton’s Star Atlas and Reference Handbook.
The primary version dates to 1910, and in 2003, Benjamin Cummings Publishing discharged the twentieth release. Norton’s contains eight diagrams.
Two roundabout diagrams demonstrate the sky to 40° away from every one of the celestial poles. Six rectangular diagrams partition the sky into sections 4 hours of right climb wide.
Each demonstrate the sky between declinations 60° to –60°. Every one of Norton’s maps are two-page forms.
Norton’s showcases roughly 8,800 stars to magnitude 6.5. It likewise indicates many double and variable stars, and in excess of 600 profound sky objects. Each diagram has two pages of records and notes about that guide’s most fascinating objects.
After numerous releases imprinted on typical paper, Norton’s presently print on glossy stock, which doesn’t retain dampness like prior manifestations. That implies the pages don’t get as wet when you see where the humidity is high.
The main part of Norton’s close to 200 pages examines sorts of divine objects, time, heavenly positions and coordinates, cosmic equipment, and how to watch. The solar system part incorporates maps of the Moon and Mars.
Another most loved atlas in the amateur classification is the Bright Star Atlas by Wil Tirion. Mainly published for clients with the smallest telescopes, the Bright Star Atlas shows stars to magnitude 6.5.
It additionally incorporates around 600 double stars, variable stars, and profound sky objects.
The Bright Star Atlas isolates the sky into four polar and six equatorial zones.
The maps incorporate constellation limits yet no constellation figures. Amplified inset diagrams demonstrate the Pleiades (M45) and the locale around Orion’s Sword.
A keyed arrangement of six discoverer diagrams indicates perusers how the atlas maps identify with the present night sky.
Wil Tirion additionally made the more comprehensive The Cambridge Star Atlas 2000.0, which includes around 900 profound sky objects to maps that plot stars to magnitude 6.5.
The 20 diagrams that make up The Cambridge Star Atlas 2000.0 demonstrate the sky in different hues: Stars are dark, the Milky Way is blue, star bunches are yellow, nebulae are green, and worlds are red.
The hues make this an alluring atlas when utilized during the day (for arranging sessions or to survey an earlier night’s perceptions), and they don’t degrade its value around evening time.
Online resources and apps for star charts for stargazing.
So far we’ve only talked about star maps and atlases that are available in print. But moving on with time, modern cosmology has evolved to be completely digitized and now can be accessed with ease right from your smartphone.
Many of the companies develop and publish their maps online for users so that it is easier for a potential beginner to quickly glance through the resource when he needs it.
A lot of these applications are also available offline which means you can still access the data without a working internet connection, making it great for people that are looking to travel for a night of joyful stargazing.
And the best part is, it can all be accessed from your phone which means that there is no need for you to carry additional things like the physical charts which can easily get misplaced, damaged or lost.

SkyView additionally incorporates a “time travel” mode that enables you to see the sky as it would have shown up previously or will show up later on, in light of what we are aware of each object’s developments.
Night Sky (iOS: Free)
Night Sky on iOS is another dazzling application that exploits Apple’s push for AR applications to convey an extremely pleasant looking expanded reality sky map.
Clients can see a great many stars, satellites, planets and constellations; Night Sky takes things further with Apple Watch bolster that brings the sky guide down to your wrist.

The new form offers up a rich disconnected database of stars, planets, and other divine objects that you can see on an AR star diagram, total with vivified perceptions and information about the history, folklore and science behind these heavenly objects.
The $2.99 Cosmos Collection in-application buy opens extra highlights, for example, described voyages through the sky, orbit mode and systems to see.
Much further developed variants, SkySafari Plus and SkySafari Pro, incorporate an extended database and more highlights, for example, support for WiFi-controlled telescopes. Android clients can in any case go to the more established Sky Safari 5.
Pocket Universe (iOS: $2.99)
Pocket Universe is another incredible across the board sky viewing application that gives both a versatile sky map just as an abundance of additional items like increased reality modes.
Clients can see a guide of the sky above, complete with marks and constellations, just as track individual objects and planets (with a “show me” mode to control your point).
An increased reality orrery gives you a chance to see the solar system in your very own living room, and the application incorporates additional exercises and assets like tests and Wikipedia connections to different objects.
