- These are reference programs that I originally wrote for my own use.
- They may be copied and freely distributed as long as they are not sold
- without my written permission, but does not exclude a charge for the disk
- and reasonable handling. Please keep all of the programs together.
-
- If you are using these programs and find them to be of value, a
- contribution would be appreciated. $30 is suggested, but feel free to
- contribute whatever you think is fair. If any suggestions, corrections,
- additions, and updates are submitted of sufficient value, I will include
- you on my registered user list regardless of the amount of the
- contribution.
-
- Anyone wanting a copy of the programs may send me $20, 2 disks and a
- prepaid mailer. If you send $30, I will take care of all the messy
- details. Please mention if you need a disk format for other than MS-DOS
- 360K.

- STAR CATALOG
- Version 5.5
-
- This version is the same as version 5 except it has been rewritten in
- the C language, and other functions have been added. Also I've made a
- few corrections and minor additions here and there. It can also now call
- the Astronomy Conversions program.
-
- This is a listing of the named and designated visible stars for both
- the Northern and Southern Hemispheres. The limit of naked-eye visibility
- is generally magnitude 6, but I included stars down to magnitude 6.5 for
- completeness. I also included some of the more interesting stars that are
- somewhat dimmer, and the stars within twenty light years, more or less.
-
- The entries should be pretty straight forward. The only abbreviation
- I used is ##.#" sep., which means "arcseconds separation." There are 60
- arcseconds to an arcminute, and 60 arcminutes to a degree. A fingertip
- held at arms length is about 1 degree wide, which can be confirmed by
- comparing with the full moon, which is a half degree wide.
-
- In multiple star listings, the first magnitude is generally the
- combined magnitude, and the second, and sometimes third, are for the
- second and third stars, respectively. I found it less confusing to do it
- this way, and a lot easier. One thing I had to contend with much of the
- time was discrepancies, quite often within the same source. A few times
- I had to resort to just plain guessing, but I think that the information
- presented here is as accurate as I can make it.
-
- I didn't include the coordinates and some other information, as there
- is only so much room on a computer screen, and I would probably still be
- working on version 4! If anyone has questions or want more information,
- just drop me a line and I'll see what I can do.
-
- There are almost 1700 entries in this version. There are a number of
- cross-referenced stars, as all of the stars with proper names also have
- Greek and Flamsteed Number designations. Also some stars have more than
- one proper name. I never did get around to counting the real number of
- stars listed.
-
- STARCAT is written in C and compiled by Manx Software Systems Aztec C
- compiler. Their address is 160 Avenue of the Commons, Shrewsbury, NJ
- 07702. I'm presently working on the next upgrade, which will add more
- stars, and upgrade the information on most of the others.

- CONSTELLATIONS 88
- Version 2.1
-
-
- This version has been completely re-written in the C language and
- compiled by Mix Software's Power C compiler. This program can now be run
- on either a Hercules card or a CGA card. It will automatically configure
- itself to whichever card you have. Of course, with the higher number of
- pixels in Hercules graphics mode, the screens look a bit smaller and are
- in the upper left as compared to CGA.
-
- Due to the pixel limitations, some of the constellation lines look a
- bit awkward, but I tried to make everything look as good as possible.
- But, as with a lot of things in life, we have to make some compromises
- here and there and live with the result.
-
- This program shows all 88 constellations in the Northern Hemisphere,
- the Zodiac, and the Southern Hemisphere. Only the stars with proper
- names are designated with their Greek letters or Flamsteed numbers. I
- would have liked to show all the Greek letters in each constellation, but
- it looked too cluttered. The constellation lines are also shown but are
- not necessarily the most common or official ones. The three maps I used
- didn't always agree so I used the ones that seemed the most logical, or I
- knew from memory to be the correct ones.
-
- The proper names are taken directly from STARCAT.
-
- I corrected a few minor mistakes in this version, and added the
- capability of turning the constellation lines on or off. Just pressing
- the "L" key will do it; it's not necessary to press the shift key also.
- It's also not necessary to press the shift key with the "?" to bring up
- the help info.
-
- Mix Software's Power C compiler is the easiest to use that I have
- seen, and also has the largest function library. I recommend this one
- for beginners, but it is also good for professional projects. It's an
- incredible bargain at only $19.95. The manual alone is worth it. Their
- address is Mix Software, 1132 Commerce Drive, Richardson, TX 75081 214-
- 783-6001.

- I've recently added a function to each of the programs on this page so
- that they handle color screens better.

- ASTRONOMY NOTES
- Version 2.2
-
- This is a listing of miscellaneous facts and figures that I've come
- across from time to time and wanted to put them in a place where I could
- find them. Its name is ASTNOTES.EXE, and has been rewritten in the C
- language. It can now call up the Astronomy Conversions program without
- having to get out of ASTNOTES.
-
- I recently added a function that will return to the same screen after
- returning from ASTCONV.EXE.
-
- This was compiled by Mix Software's Power C compiler.
-
-
- SOLAR SYSTEM
- Version 4.2
-
- This is a listing of facts and figures about the planets, moons, and
- asteroids of the Solar System. All of the measurements are in the metric
- system. Its file name is SOLARSYS.EXE and was also rewritten in the C
- language. It can also call up the Astronomy Conversions program, and was
- compiled by Mix Software's Power C compiler. I hope to add graphics to
- this one someday.
-
- This has also been modified to return to the same screen after
- returning from ASTCONV.EXE. Also, I added the names for the newly
- discovered moons of Uranus, and a name (Helene) for one of the moons of
- Saturn.
-
- CONSTELLATION NAMES
-
- This is a list of the constellation names with their abbreviations and
- other information. It is just a reference list and is not copyrighted.
- It's only along for the ride. Its file name is CONSTNAM.EXE, and I wrote
- it in the C language for practice.
-
-
- ASTRONOMY CONVERSIONS
-
- This is a public domain program that I converted from BASIC to C as an
- exercise, and was compiled by Manx Software Systems Aztec C compiler.
- It's included for the users convenience.
-
- I recently re-worked the front end as I got tired of going in and out
- of menus all the time just to get a conversion or two.
-
- This program has to be located in the default drive and directory so
- the other programs can find it.
