That over with, I hope you find these utilities useful.

Stellarium Hevelius Constellation Art

Hevelius - Lyra

Still very much a work in progress, I have used the Hubble Source high resolution scans where they are available. For the other constellations I have used images from Wikipedia and cleaned them up by hand.

As Hubble Source adds more high resolution scans I will include them in this sky culter, also as I find and process more low resolution images I will provide updates.

No installer - just unzip the contents of the file below into your Stellarium\skycultures folder.

Last update 11/10/25.

Iris Looper

This simple little script allows you to run a FOR NEXT loop against the Iris Command window with access to an incremental variable. It is pretty crude with no input checking, so make sure you type your inputs accurately.

Updated: 4 Nov 2007, ver 1.1 due to change in source URL.

Note: If you have problems with the executable, there is a full installer for the editor that will also register the required VB6 controls.

Application Notes

TheSky PE Comet Editor

This is a really simple utility, it can either open a file in one of three ways (the text files are in SkyMap Pro format - 'cause that's what I use!).

The comets contained in the file will then be listed in the utility. Select the comets that you want to be configured for TheSky PE by checking the tick box next to them.

Finally click "Write SkyPE File" to create a file in TheSky PE format. Then use ActiveSync to copy this file to the SkyPE folder on your Pocket PC.

Photoshop LRGB Actions

Copy the action file to your Photoshop actions folder. On my system this is located in...

C:\Program Files\Adobe\Adobe Photoshop CS2\Presets\Photoshop Actions

Paste each of you colour images as a new layer into your composite image.

Highlight each layer in turn, and run the corresponding action. The layer will be renamed, colourized, and two correction layers added (Curves and Levels).

Normally you will just use the R G B or L R G B actions, but I've also included a other layers for narrow band images.

Launch SkyMap Pro

Extract the program (LaunchSkyMapPro_V2.exe) from the zip file and place it in your SkyMap Pro application folder.

Create a shortcut to the LaunchSkyMapPro_v2.exe on your desktop or start menu etc. (There is an example shortcut for SMPro v11 in the zip file).

Option 1. Have SkyMap Pro start with the initial map set to a fixed time of the current day.

In the shortcut properties add the parameters "/t hh:mm" where hh:mm is the desired map time. The 'Target' should then look something like this:

"C:\Program Files\SkyMap Pro 11\LaunchSkyMapPro_v2.exe" /t 21:30

Option 2. Have SkyMap Pro start with the initial map set to the onset of darkness for the current day.

In the shortcut properties add the parameters "/d hh:mm" where hh:mm is the default map time to use if there is no darkness on the current day. The 'Target' should look something like this:

"C:\Program Files\SkyMap Pro 11\LaunchSkyMapPro_v2.exe" /d 22:00

The utility will launch SkyMap Pro from the current folder (or use the currently running version if there is one) and set the map time. It will take SkyMap Pro out of real time mode if required.

Please note that the /d option will only work on SkyMap Pro versions 10 & 11. The /t option works on versions 10 & 11, but may work on earlier versions - it hasn't been tested though.
