CHARA is a complete, all-in-one application originally designed for my observations at the eyepiece, and which I have used successfully (apart from a couple of bugs which proved useful in redesigning this all-singing, all-dancing version here) for a couple of years. My original version consisted simply of the one screen for bringing up star charts and entering observation details. This version however consists of three screens each with a different function. These three functions are:
A few points to note: first, please read the attendant help, since this contains details of where you should store your charts and what to call them. If you do not do this, the app will not work as it should. Since this app may be used by people with different preferences, a standard format had to be chosen. Basically, all charts should be named after the star (so ss cyg.gif for example) and be in the .gif format since not only does this minimise file size, but is the only file format the app allows. Even the most basic image app such as paint will allow you do export as .gif files, and more advanced programs such as photoshop will permit mass-export of many files at once.
You can download CHARA from here as a zip file (about 30MB). Run the setup file and on installation if asked to install various data access components, just say yes. The app installs successfully on my at-the-scope laptop, which is XP, and also on this present system which is Windows 7.
The first time the app is run it will create the folders where you store your charts, the native database, and the folder for your AAVSO files. When you come to upload your report to WebObs, this is where your files will be located.
It will also write a 'dummy' record for SS Cygni in the charts database, so you can practice with it if you want in the database screen - though if you want the observation screen to display it, you will of course have to have a properly-named chart for SS Cyg! Obviously you won't be able to use the app for observing until you actually have charts installed in the charts folder.
You don't of course have to use the app to its full potential; you may simply want to download your AAVSO observations into the database to look at them.
Finally on the subject of databases - the charts database is accessible only through the app itself. Even if you have good old Access 97 (which the app uses) you probably won't be able to open it from there unless you are a master hacker. Sorry - this is a security measure.
Also note: At the moment CHARA is suitable for visual observers only. Discussion with AAVSO staff may engender development for other forms of observation if there is a need.
Although I have tested the 'personal' version myself, this extended app has not been used in the wider astronomical community, so I would be pleased to receive details of any problems users may encounter. You folks are, to some extent, guinea pigs! Feel free to contact me via the email link on my AAVSO profile space.
