Presented for your enjoyment and edification are the following tips that may provide some assistance to those who are just starting out in amateur astronomy.
Nightwatch: A Practical Guide to Viewing the Universe by Terence Dickinson is considered by many to be the single best book for novice amateur astronomers. As far as other beginning observing guide books are concerned, I highly recommend Phillip S. Harrington's Star Watch: The Amateur Astronomer's Guide to Finding, Observing, and Learning About over 125 Celestial Objects and Turn Left at Orion: A Hundred Night Sky Objects to See in a Small Telescope--and How to Find Them by Dan M. Davis and Guy Consolmagno. Star-Hopping for Backyard Astronomers by Alan M. MacRobert is an excellent book on learning the technique of star-hopping but, unfortunately, it's out of print. Another out-of-print book that's worth looking for is Deep-Sky Observing with Small Telescopes by David Eicher.
At a more advanced level, The Backyard Astronomer's Guide by Terence Dickinson and Alan Dyer is a worthy guide to astronomy and amateur astronomy. Another very good, yet inexpensive, source of general information is A Field Guide to the Stars and Planets (Peterson Field Guides) by Jay M. Pasachoff. Yet another is Stars and Planets: The Most Complete Guide to the Stars, Planets, Galaxies, and Solar System - Updated and Expanded Edition (Princeton Field Guides) by Ian Ridpath and Wil Tirion.
Sue French's Celestial Sampler: 60 Small-Scope Tours for Starlit Nights and Deep-Sky Wonders: A Tour of the Universe with Sky and Telescope's Sue French are two other fine books to consider.
The Observer's Sky Atlas: With 50 Star Charts Covering the Entire Sky by Erich Karkoschka and Objects in the Heavens by Peter Birren are two inexpensive but very handy atlases/field guides.
For more advanced observers, The Night Sky Observer's Guide is the best one currently available.
As far as books on astronomy gear are concerned, the final edition of Phil Harrington's Star Ware: The Amateur Astronomer's Guide to Choosing, Buying, and Using Telescopes and Accessories is now dated but nevertheless contains some excellent information. Astronomy Hacks by Robert Thompson and Barbara Thompson is another highly-recommended book full of great tips on equipment and the art of observing. For recent reviews of astronomy equipment, the periodical Astronomy Technology Today is a good source.

Active observers may eventually desire a paper star atlas in order to locate various stars and deep-sky objects or DSOs. Paper star atlases run the gamut from the simple and inexpensive to the complex and costly. Here are a few to consider: Orion's DeepMap 600, Norton's Star Atlas and Reference Handbook, 20th Edition by Ian Ridpath (Editor), Sky & Telescope's Pocket Sky Atlas and Pocket Sky Atlas – Jumbo Edition by Roger W. Sinnott, the Bright Star Atlas 2000.0 by Wil Tirion and Brian Skiff, and The Cambridge Star Atlas by Wil Tirion. The Sky Atlas 2000.0 by Wil Tirion is a more advanced and expensive atlas. The Uranometria 2000.0 goes even "deeper" in stellar magnitude and displays the positions of a greater number of deep-sky objects. The newest high-end star atlas is the interstellarum Deep Sky Atlas.

A wealth of good astronomy freeware is listed at https://www.skyandte...-and-shareware/ and https://listoffreewa...ftware-windows/
Stellarium, Cartes du Ciel, and C2A are all fine freeware planetarium programs. Celestia is a simulator program. The Virtual Moon Atlas - which can be downloaded without cost at http://www.ap-i.net/avl/en/start - is a great aid for lunar observing. There are also many excellent commercial planetarium programs on the market, including MegaStar, SkyMap, Sky Tools, Starry Night, and TheSky.
SkySafari is an excellent planetarium program and much more.
Two planetarium programs and an app are discussed briefly at http://jeffpolston.com/software.htm

Binoculars are a great way to get started in observational amateur astronomy. These instruments are relatively inexpensive and are eminently portable and easy to use. Using both eyes definitely enhances the visual experience.
Binoculars are ideal for showing the "big picture". They can readily display objects that are too large to fit into the fields of view of most telescopes. In addition, binoculars can often be useful in "surveying" the area where an object is located prior to conducting a telescopic star-hop.
A surprising number of celestial objects, including many binary stars, open and globular star clusters, nebulae, and some of the brighter galaxies, can be detected with binoculars. Scanning through the heart of the Milky Way with a binocular from a very dark site is a very memorable experience.
I recommend purchasing a 10x50 (i.e., 10 power and 50mm aperture) binocular for astronomical use. A 10x50 binocular is usually not overly heavy for most people to hand-hold and provides a 5mm exit pupil that will be appropriate for most observers when age and observing site darkness are taken into account. People who must wear eyeglasses while observing may want to look for a binocular with at least 14mm of eye relief.
Most binoculars are made in China nowadays and are sold by a variety of vendors under a host of different brand names. Some of them have surprisingly good optics. Celestron, Nikon, Oberwerk, Orion, and Pentax are good mid-price brands to consider.
Reclining in a lounge or zero gravity chair makes hand-held binocular observing far easier.
Mounting a binocular on a tripod or a dedicated binocular mount (guider) will improve views markedly. Information on binocular mounts is posted at http://www.cloudynig...ts/thoughts.pdf and http://binocularsky....binoc_mount.php
An alternative method of mounting binoculars is discussed in the article posted at https://skyandtelesc...our-binoculars/
Image stabilized binoculars are very expensive but work very well indeed.
A glossary of optical terms pertaining to binoculars is posted at https://www.bestbino...-binoculars.php
Articles with advice on buying binoculars and with discussions regarding the physics of magnification and other aspects of binocular performance can be found at the following URLs:
In my opinion, the best binocular observing guidebooks currently available are Touring the Universe through Binoculars: A Complete Astronomer's Guidebook by Phil Harrington, Binocular Astronomy by Craig Crossen & Wil Tirion, Binocular Highlights: 109 Celestial Sights for Binocular Users by Gary Seronik, and Observing the Night Sky with Binoculars by Stephen O'Meara.
Phil Harrington discusses various targets in his Cloudy Nights Binocular Universe column at http://cloudynights....category_id=182 and in a monthly column in Astronomy. He offers an excellent freeware planetarium program known as TUBA (Touring the Universe through Binoculars Atlas), which also includes information on purchasing binoculars, at http://www.philharrington.net/tuba.htm

Sketches of a number of deep-sky objects as seen through binoculars can be found at http://rodelaet.xtre..._astronomy.html
The vast majority of deep-sky objects visible in amateur telescopes are quite faint and are best seen from a dark location. Stargazing from light-polluted locales can be quite challenging. However, there are a number of DSOs that can be seen by urban observers. The Moon, the bright planets, bright binary stars, bright open and globular clusters, bright nebulae, and bright galaxies are all possible targets.
Light pollution reduction and nebula filters may be useful to some degree on certain nebulae. However, the rising use of broadband LED lighting may render such filters ineffective.

Urban astronomy is also discussed at these sites:
Books on the subject include Urban Astronomy by Denis Berthier and The Urban Astronomer's Guide: A Walking Tour of the Cosmos for City Sky Watchers (Patrick Moore's Practical Astronomy Series) by Rod Mollise.
