    I have created a script for AstroArt 9 which picks up a target list from another text file. It creates a new directory based on the date the script is run and automatically saves all the images based on the target number and name and the Julian date (this is so that if you take another set of images on the same object on that day they are not overwritten). The target list text file does not need to have the correct RA and Dec as this is calculated during running of the script. It also automatically gets the magnitude of the object from the built in star Atlas and or the MPCOrb dat. The Object magnitude is used to control the exposure time. You can choose an area of the sky for imaging based on hours before and after the meridian and limits on altitude, along with a maximum magnitude figure, any objects that do not match all these variables are skipped, the script loops through the list as many times as you desire so during the course of a session some objects will enter and leave the observing window. It drives the telescope to the object, does a full frame autofocus then a short imnage to check position and if necessary correct it then it starts PHD2 and takes a sequence of images and saves them to your chosen directory. It also creates a log file (.csv file) with a line for each image and saves this to your chosen location. The longest continuos run I have had with it was 10 hours where it performed with no problems and even coped with intermittent cloud cover, all the targets were visible on the images. I am using it for Asteroid light curve work but it could equally well be used for variable star, exoplanet, comets (although the magnitude information would need some changes), Deep sky imaging. If this is of interest please let me know and I have attached a copy of the script and the target list file. Some of the commands in this script are yet to be released, I have been working closely with the author of AstroArt and he will send a pre release of Service Pack 4 to anyone who wishes to use the script. It may be possible to get it working with some reduction in functionality using earlier versions of AstroArt. If you would like to get involved with the Asteroid and Remote Planet Section asteroid light curve work that would be appreciated. If any one from another section would like to use it and needs help to create a target file based on their needs let me know.
