SKY:Lab® Astronomy Software Newsletter November 2003                       www.skylab.com.au

Dear STAR Atlas:PRO User,

Welcome to the latest edition of the SKYLab Astronomy Software Newsletter, issued periodically to keep you in touch with the latest STAR Atlas:PRO software upgrades and other related news.

The latest version of
STAR Atlas:PRO, Version 5.2, is now available as a free upgrade to all registered users.

Major new features include a new Day Mode colour scheme that switches STAR Atlas:PRO's colour scheme to tones of the colour grey for daytime use, or back to tones of red and black for dark adaptation.

There is now improved
support and additional features for the Argo Navis™ Digital Telescope Computer and support for
High Precision Telescope Pointing for Meade Telescopes.

A
greatly expanded collection of Star Names ultimately improves star labelling on charts and can also list other names and historical names that a Star has previously been known by.

Another new feature generates star charts as Postscript files which may then be printed at the highest possible resolution on your printer, transformed into an Adobe PDF file, or used in typesetting applications.

There are also dozens of minor corrections and improvements that will improve STAR Atlas:PRO overall.
Following is a more complete description of Version 5.2 and introductory details for using each new feature.

Finally you will find instructions on to download and install the Version 5.2 Upgrade Package.

I hope you enjoy the latest version of STAR Atlas:PRO.

Clear Skies!

New Daylight Colour Scheme
Since it's inception STAR Atlas:PRO has maintained it's red and black colour scheme to suit dark adaptation. However with STAR Atlas:PRO being used more and more at the desktop a new colour scheme is introduced in this version. The new Day Mode colour scheme consists of a mixture of grey colours similar to those of typical software applications that run on Windows.

How to toggle between Night and Day mode colour schemes.
1. Select [Chart Prefs] from the main floating menu.
2. At top right of the Chart Preferences and Program Settings window you will see the two new buttons, [Night] and [Day], select either to suit your preference.

Improved collection of Star Names
The number of common Star Names is greatly increased resulting in improved star labelling and a new easy way to lookup and locate Stars by name.

To Locate a Star by name.
1. Choose [Locate] from the main floating menu.
2. Choose menu number [57] Star Names.
3. Choose [Find Star] from the Star Names window that appears.
4. From the quick locator buttons along the top of the window, choose the letter that beginning letter of the Star you are looking for. As an example, if you are looking for the Star called Rigel, click the [R] button and then all star names beginning with the letter 'R' are listed in the window.  You can then double-click to select Rigel from the list, you are returned to the main Star Names window where you can click [MAP] to locate the Star position.

Bright Comets now displayed on Sky Chart
STAR Atlas:PRO's Sky Chart now displays Comets brighter than Magnitude 10, making it easy to spot the brightest Comets in the Sky.

2. then choose [ Connect ] to make a connection with the Argo Navis.
3. Once connected, select [ Argo Navis Panel ] from the Scope Control Toolbar (menu) that appears after STAR Atlas:PRO makes a successful connection to the Argo Navis. The Argo Navis Panel window that appears automatically displays the Internal Unit Temperature, Altitude and Azimuth Encoder Step Positions and Internal Date and Time. The values display are for the current instant and are updated if you click the [Refresh] button.

How to download Observation Planner Objects into the Argo Navis
.
1. Choose  [ Scope ] from the the main floating menu,
2. then choose [ Connect ] to make a connection with the Argo Navis.
3. Once connected, select [ Argo Navis Panel ] from the Scope Control Toolbar (menu) that appears after STAR Atlas:PRO makes a successful connection to the Argo Navis. The Argo Navis Panel window will then appear and automatically display the current R.A. and DEC. values along with Internal Unit Temperature and other values. Note: the command buttons are disabled whenever communications between STAR Atlas:PRO and the Argo Navis are in progress.
4. Choose the [Export] button to start the download process. Following the instructions that are displayed by STAR Atlas:PRO, which tell you how to setup the Argo Navis so that it is ready to accept the download of objects from STAR Atlas:PRO (the lower part of the STAR Atlas:PRO screen contains the Argo Navis User Catalog command section, each command is explained in the following table ).

User Catalog commands.

[Purge]

New Default BAUD Rate Setting for Argo Navis Driver.
When you select the Argo Navis telescope driver in [Chart Prefs]
[Telescope Setup] → [Select Driver], the Baud Rate now defaults to 38400 (this is the manufacturers default Baud rate setting for each of the Argo Navis Serial Ports).

Improved Meade Telescope Driver
STAR Atlas:PRO's inbuilt Meade LX200 driver now supports Meade's High and Low Precision Telescope pointing modes.

For further information on High and Low Precision Telescope pointing modes, consult your Meade Telescope manual.

Low Precision Mode provides Telescope Pointing accuracy to 1/10th of an arc-minute in Right Ascension and to the nearest 1 arc-minute in Declination.
High Precision Mode provides Telescope Pointing accuracy to 1 arc-second in both Right Ascension and Declination.

How to toggle High & Low Precision Telescope Pointing Modes.
1. Choose  [Scope] from the main floating menu
2. Choose [Options] from the Scope Control menu that is displayed
after a successful connection is made to the Telescope.
3. Click the [ High / Low Precision Mode ] button to toggle STAR Atlas:PRO and the Telescope between High and Low Precision Pointing modes.

Note: Each time STAR Atlas:PRO is started, it assumes your Telescope is set to Low Precision Mode.

High Resolution Postscript Charts
STAR Atlas:PRO's new Postscript feature allows you to output the displayed chart to a Postscript file.
The Postscript star chart may then be imported by a variety of other software applications to produce high resolution Adobe PDF (Portable Document Format) files for printing, viewing, and easy publication. Applications that can import Postscript files include GSview (see http://www.cs.wisc.edu/~ghost/gsview/ ), Adobe Distiller and Jaws PDF Creator.

How to generate a Postscript File for the displayed chart
1. Choose [ Print ]
from the main floating menu
2. choose [ Postscript File ]
(Note: STAR Atlas:PRO will then generate a postscript output file called "starpro.ps" , you can choose another file name and/or folder to store the file).
3. Use a Postscript compatible software application that can open Postscript files to print, display or export the chart to an Adobe PDF file.

Precessing Telescope Co-ordinates
Telescopes and Digital Setting Circles (including the Argo Navis) may report their pointing co-ordinates for the Epoch of the instant in time when the telescope is being used, which do not match the J2000.0 Epoch of STAR Atlas:PRO charts. This results in some inaccuracy when plotting the pointing position of the telescope on a STAR Atlas:PRO chart.

Applying precession to Telescope Co-ordinates.
1. Choose [Scope] from the main floating menu
2. Choose [Options] from the Scope Control menu
3. Enable [
] Precess Telescope co-ordinates option.

Minor Corrections and Improvements
-
Celestial objects with a Magnitude of 0.0 (zero) are no longer erroneously displayed in Sky Chart mode.
- Some Time Zones located West of Greenwich, were miscalculated when selecting the Observer's Location from the list of choices.
- The Planetary database now displays the current actual distance to each Planet in kilometres.
- The Interval between Position Updates setting in [Chart Prefs]
[Telescope Settings] function is improved.
