Quote:I couldn't get PEMpro to work. I have the older controller. I was using my guide camera to try to get it work, an Orion SSAG.Which is plugged into the the ST4 port and then USB'd into my computer. It was not recognizing the mount. Should I have had the RS232 cable plugged from the mount into the computer as well or is that guide scope setup enough? Also what other software do I need for PEMpro to work? Thanks!
Quote:I think with 8406 you can guide with PEC on through the standard ST4 port. I can check that next time I am under the stars

Quote:It has been recommended that I begin at an image scale of no less than 2 arc-seconds/pixel. At that scale, the Ring Nebula occupies only 75 pixels. Rather than start with something small and cheap and upgrade repeatedly until I find a satisfying combination of mount and telescope, I would prefer to do enough research to jump straight to the final one.
Quote:Hi-I just noticed you may be using a DSLR. In that case you can't measure with the raw images very well and you need to debayer them first. So I would calibrate them with darks/flats/bias - or however you do it - then debayer - then measure fwhm.Frank
Quote:Alfredo,You could also get a trial of CCD Inspector. You can easily measure FWHM of several images. It is a good tool for analyzing your images to help troubleshoot issues with your imaging system. http://www.ccdware.com/products/ccdinspector/
