- REVIEW
-
- Recently, Mike Smithwick, author of Distant Suns, posted an article
- in one of the newsgroups (comp.sys.amiga.applications I believe) with the
- sad news that support has been dropped by Virtual Realities for Distant Suns
- on the Amiga. This came as a blow for astronomy lovers like myself who were
- expecting an upgrade notice instead. Once again, I felt the pang of
- disappointment that Amiga Users everywhere have become quite familiar with
- over the past few years.
-
- Just weeks later I came across a huge file, "Digital_Universe_Demo,"
- that was 3.3 MB long. Normally, I would have ignored it (my modem is 14.4K
- bps) but the astronomy category sucked me in. I installed it and to use an
- old cliche, "it blew my socks off!" I ordered it two days later.
-
- This program requires MUI. I am neither friend nor foe of MUI. It
- is already on my system for the usual reasons, and I have never felt that I
- suffered from the problems which have been reported by some users. This
- program has never crashed or locked up, and is not slow compared with
- Distant Suns on my system. You will need lots of disk space and memory and
- will want reasonable processor speed and an FPU.
-
- This is one of the NICEST programs I have ever seen on an Amiga
- computer, PERIOD. The features are so numerous it is difficult to list them
- comprehensively. Even with an extra 20,000 star-set and an image set
- addition to Distant Suns 5.0, my DS directory is 4.6 MB and my Digital
- Universe directory as supplied is 17.85 MB! Some of the features are:
-
- o Yale Bright Star (YBS) Catalogue of 9110 stars.
-
- o Smithsonian Astrophysical Observatory (SAO) Catalogue of over
- 250,000 stars.
-
- o Messier's Catalogue of 110 deep sky objects (galaxies, nebulae, and
- clusters).
-
- o Sky & Telescope's NGC 2000.0 Catalogue of 13,226 deep sky objects.
-
- o Jost Jahn's comet database containing 2298 cometary orbits.
-
- o Jost Jahn's minor planet database containing orbital information for
- thousands of asteroids.
-
- o Orbital information for approximately 900 Earth-orbiting satellites.
-
- o Can generate accurate views of the night sky for any date from
- 100,000 BC to 100,000 AD.
-
- o Over 700 pages of hypertext with over 250 pictures (AmigaGuide)
-
- o Typical accuracies of better than 1 arcsecond (1/3600th of a degree).
-
- o A context-sensitive help system
-
-
- The program can use several levels of accuracy depending on your
- needs. Star computations are fast on my system, and faster than Distant
- Suns, considering the greater number of objects being calculated. If you
- zoom in on Saturn, you will soon see a bulge (the rings) and if you continue
- zooming in you will see this perfectly rendered image of Saturn and its
- rings, all oriented correctly right down to the edge on view of the rings
- which is the case for Saturn at this time. The moons come into view, all in
- their accurate positions. Zooming on a moon will show its shape, a grid
- showing the poles, equator and orientation.
-
- Clicking the mouse on a star results in an information window with
- an amazing amount of scientific and useful information. Once you have
- scrolled through all the information, click on "More Info.." at the bottom
- and the hypertext encyclopedia opens with more information, historical data,
- all the names this star has been called through history, pictures and so
- on. Exploring the skies, looking at pictures, hearing audio in some cases
- and checking out the encyclopedia will consume an evening in short order. I
- was peeking at Pluto one evening and was surprised to see Clarion (Pluto's
- moon) swim into view.
-
- Setting your environment (latitude, longitude) is as easy as
- scrolling through the HUGE list of cities and clicking on where you live. I
- don't know how complete the list is, but I found Regina, Saskatchewan
- (Canada) in there which was just great for me! You even set your altitude
- and outside temperature.
-
- Printing at any point is through the preferences printer and prints
- at the maximum resolution your printer allows. In addition, screen shots
- can be saved as IFF ILBM's. The screen can be of any size depending on the
- amount your chip/video memory.
-
- The program was developed entirely on the Amiga. I found everything
- "as it should be on the Amiga" with no nasty surprises. I had no crashes at
- any time, nor any hint of problems. This is often not the rule for brand new
- software as we all well know. This is the largest program I have had on my
- Amiga and I was expecting some "trials and tribulations" Once installed
- though, it gave new meaning to the idea of "Plug-n-Play" I wonder if the
- developers would consider a complete Internet package?
-
- The program runs on a number of graphics boards, but I don't own one
- yet, so couldn't test this.
-
- Who is Syzygy Research & Technology Ltd. from Legal AB.? It's worth
- a phone call just to hear how they pronounce their name! I sent e-mail to
- Dan a couple of times, and got immediate replies back. I ordered my copy by
- e-mail, then phoned my VISA number to them.
-
- A favourite item in The Digital Universe deserves special mention.
- There is a report generator. It will either print or send to a file a
- report consisting of fields all selected by you. There are many choices.
- Just for example, you can select Moon of Earth, and select phase angle,
- azimuth, rise/set times, etc. for say, two weeks and each 24 hours and out
- comes a report for these moon conditions for the month. That is just one
- thing out of many choices of the kind of reports it will generate.
-
- The Digital Universe may not perfect, but it sure comes close,
- especially for the price. I hope they develop more software. My PC friends
- won't hardly talk to me since they have seen this program cook! I should
- say that I do not know the developers, have never met them, or heard
- anything about them until the demo showed up in Aminet. My enthusiasm for
- this program is entirely my own. It is a great boost to the Amiga and those
- interested in science and astronomy.
-
-
- BUGS
-
- There is a reported bug where the system could crash on the intro
- screen with some graphics boards. There is a second icon with no intro for
- anyone who might experience this problem.
-
- There may be other bugs, but I have not wandered across them yet.
-
-
- LIKES
-
- o When you click on a star, there might be actually more than
- one star in your target crosshair, even if you didn't see
- it. In this case, a small window pops up with a list of
- candidates which were within the "target."
-
- o Nice search facility with extensive wildcard support for
- the massive encyclopedia.
-
- o If you make a mistake resulting in an unwanted screen update
- and recalculation, you can abort with a mouse click without
- having to wait for the recalculation to finish. Nice for
- slower machines, or for very high-accuracy views.
-
- o Build your own horizon in a text file with any editor. 360
- lines of text define each degree's elevation of your horizon.
-
- o Produce stand-alone IFF Animations viewable with ShowAnim.
-
-
-
-
- DISLIKES AND SUGGESTIONS
-
- o No Arexx interface.
-
- o I miss a summary window for quickly seeing the moon and its
- current phase and rise/set times for objects in our solar
- system.
-
- o Date and time take up too much width in reports. I'd like
- to have more choice on how dates are formatted and whether
- the year needs to always be included or not. If you
- generate a report on moon rise & set times for a month, you
- don't need the month and year printed out 30 times in all
- those columns. I'd like to be able to get 30-Oct-95 instead
- of 30-10-95 or is it 10-30-95??
-
- o Can't save the current state. It would be nice to set view
- direction and field of view and have it saved for the next
- start-up.
-
-
- CONCLUSIONS
-
- This is an incredible piece of software for those who have great
- interest in astronomy. One PC user spent a whole evening looking at this
- program. He has his own observatory out on the farm and knows more about
- astronomy than I. Now he is looking for a used Amiga so he can use the
- program. We could use more of this type of interest in the Amiga! No
- kidding!
