PemPro and the SPC900NC
March 22nd, 2010
If you have been looking to get accurate periodic error correction then you have probably found your way to PemPro by now. If you have an SPC900NC webcam, like many of us do as it is the default model for long exposure modification, and you have found PemPro, then you have likely found out that the two of them together makes for rather a mess. Pempro crashes every time you try to set the exposure levels for the cam.
Here is a quick way round that, you will need some software that works with the webcam, I use the free version of K3CCD Tools and WcCtrl (web cam control) to manage the webcam settings.
- Start K3CCD, centre a star and set the correct exposure and gain to get the image.
- Start WcCtrl, connect it to the webcam so that it inherits the settings, I’ve found WcCtrl won’t let you switch to manual exposure by itself.
- Stop K3CCD, leave WcCtrl open and start PemPro.
PemPro will now run with the webcam settings defined in WcCtrl, and you can now use the software to sort out your PEC.
