- Introduction.
-
-
- The Night Sky is a computer planetarium capable of plotting
- depending on your disk system, either 24,000 stars to magnitude
- +7.49, or 45,000 stars to magnitude +8.49.
-
- The Night Sky is a very easy to use menu - driven program.
- This program was written by an amateur astronomer who, when
- he is not looking at the stars, drives a London Transport bus.
-
- He has spent many hours working on this program, which was
- originally started as an excise in programming. Only when it was
- almost finished did the author think of distributing it as a
- shareware program. He hopes you enjoy this program and perhaps
- become interested in looking at the real night sky.
-
- The author would like to thank David Belinfante for his kind
- help in testing the Hercules version and writing the Hercules
- graphics version of the Moons disc.
-
- A.C.Stevely is member of the user supported software association
- (ussa). ussa wants to make sure the user supported software
- principle works for you. If you are unable to resolve a
- software-related problem with a ussa member by contacting the
- member directly, ussa may be able to help. The ussa Mediator can
- help you resolve a dispute or problem with a ussa member, but does
- not provide technical support for members products. Please write

- Configurations supported.
-
-
- The Night Sky runs on any IBM personal computer (PC, AT, XT)
- or true compatible. For example, The Night Sky was written
- with a Amstrad 1512 PC and a Viglen 80386 SX. The program supports
- all computer systems:
-
- Hercules (R) CGA EGA VGA
-
- Using MS-DOS 2.0 or later, the program also supports all disk
- drive systems.
-
-
- The Night Sky Disks.
-
-
- The Night Sky program was distributed to the shareware libraries on
- four standard 360 K 5.25 inch disks. You should now make a backup
- copy of The Night Sky disk set and mark the disks.
-
- 1) NIGHT 2) STAR DATA 3) SOLAR 4) STAR ATLAS
-
-
- When using the program in a single or double drive mode the Night
- Sky program will ask you to remove and insert these disks using the
- above names.
-
- The disk set contains the following files.
-
-
- Disk one. (NIGHT)

- Running The Night Sky
-
-
- To run this program first load MSDOS. If you wish to print
- any of the sky maps, now load GRAPHICS,to prepare your PC
- to print graphic screen displays. (CGA mode only) Please note
- this program reads the system clock. On some computers (i.e
- Amstrad's) the clock runs slow if you load the program Mouse.Com.
-
-
- CONFIG.SYS
-
- When you first start up your PC, the text file CONFIG.SYS is
- automatically processed by MS-DOS. You should have the
- following commands in that file. For example, my CONFIG.SYS
- file reads as listed below.
-
- Files=20 Buffers=5
-
-
-
- 5
-
-
- The files command sets the number of files that can be opened
- simultaneously. The Night Sky will open simultaneously in
- some of the programs up to 9 files. The buffers command sets
- aside an area of memory for holding data being moved back and
- forth between the disk and the program.
-
- Please note that this version does not require the DOS file
- Command.Com to be copied onto the NIGHT disk for users with a
- double disk drive.
-
- So after loading MSDOS etc, type NIGHT and press Enter to
- load and run The Night Sky.
-
- You will first be asked if you wish to skip the configuration
- mode. The configuration mode sets your computer system and disk
- type. Your location is also set and then will be written to the
- HOME.DAT file. When first used the program is set to the
- following location.
-
- Latitude 51.28 North
- Longitude 000.01 West
- Name of Location Saint Johns
- Country England
- Time Zone 0
- Correction for daylight saving 0
-
- The first time you use this program you will most likely press
- U,as in - <U>se the same location as Saint Johns. Later on, you
- will have to set the program to your own location by pressing C,
- to <C>hange the location, or by pressing S, to <S>elect a city.
- The latitude and longitude, including the time zone settings are
- used for plotting your local sky and the rising and setting times.
-
-
- The locations you can select are :-
-
- Greenwich Bristol Birmingham Manchester
- Edinburgh Glasgow Paris Berlin
- Rome Athens Moscow Peking
- Tokyo Jakarta Cairo Khartoum
- Dakar Lusaka Sydney Montreal
- Anchorage Dallas San Francisco Mexico City
- Bogota Rio de Janeiro Honolulu Saint Johns
-
-
- If your city is not on the list then you will have to look up
- the latitude and longitude of your city in an atlas. To set
- your town or city, just follow the instructions and the
- program will write your location into the HOME.DAT file. If you
- are using disk drives, leave the write protect tab off.
-
-

-
-
- After reading your location, the program will now show the
- Main Menu, where you will be given the following choices:-
-
- NIGHT SKY
- 1....Stars 2....Planets
- 3....Comets 4....Local sky
-
- SOLAR SYSTEM
- 5....Eclipses 6....Sun
- 7....Moon 8....Jupiter
- 9....Transits
-
- STAR ATLAS
- 0....Night Sky star atlas
-
- <Q>uit to MS-DOS

- astronomy.
-
-

- Bright star catalogue, Deep sky catalogue, 21 brightest stars
- and an Atlas.
-

- SHAREWARE
-
-
- Shareware is the distribution of software by which the value
- of a program is best determined by the user of that program.
- While the copying of this program is encouraged, it should be
- distributed in an unmodified form and no charge made, expect
- for a small fee for postage and materials. Copying of The
- Night Sky is allowed for the purpose of backup and to allow
- others to try out and evaluate the program.
-
- If you found The Night Sky useful and enjoyable please think
- about registration. The author has spend many long and arduous
- hours working on this program.
-
- The cost of registration is only 30.55 (Pounds Sterling).
- Registered versions can be ordered from THE PUBLIC DOMAIN SOFTWARE
- LIBRARY Ltd. Winscombe House, Beacon Road, Crowborough, Sussex
- TN6 1UL, England. (ACCESS or VISA cards)
- Telephone 0892 663298 Fax 0893 667473
-
-
- Registration provides other benefits, such as support. You will
- also receive any one of the following versions, all contain the
- same programs.
-
- i/ Four standard 5.25 inch 360K disks. plots
- 24,000 stars to magnitude +7.49.
-
- ii/ Six standard 5.25 inch 360K disks. Which is
- version i, plus two extra disks for hard disk
- users. Plots 45,000 stars to magnitude +8.49.
-
- iii/ Three standard 3.5 inch 720K disks. Plots
- 45,000 stars to magnitude + 8.49.
-
- The author would be interested in any comments on improving this
- program. Some of its better/best ideas came from suggestions by
- registered users. While this program as been fully tested, no
- doubt some minor errors will have crept in. The author would also
- like to hear about them.
-
- Registered users will always receive free copies of any later
- updates to the program. The way it works is I write and tell you
- about a new version, you send me blank disks and I return the new
- version.
-
- You may if you wish, print the order form by using the file
- ORDER.FRM on the NIGHT disk.
