I'm new to StarGazersLounge so I've just been having a look around and found this Marathon thread. What a read with so many topics covered! It particularly interested me as I have a 383L+ mono. It's my first CCD camera so I can't really comment on its relative merits but I am very satisfied with it. Being a bit of a Luddite I tend to use the software that comes bundled with any hardware that I buy and for the past year or so I have happily used Artemis Capture. But one point raised by ollypenrice way back in this thread (on page 5 I think) caught my attention as perhaps being worthy of mention now. In relation to Artemis he(?) said “I don't use the Camera Rotate 180 option because you can get in a pickle with upside down darks and flats. If I want to reframe after the flip I open the pre-flip image in whatever software and rotate it so I frame the flip to that.” It took me some time to work out why my darks and flats didn't work after doing a meridian flip and then using the camera rotate option so as to be able to use the same star map that had been constructed for the pre-flip images. The answer I found was to use ImagingMap, a free download from www.davesastrotools.weebly.com. Any star map created with this software can be rotated 180 degrees so the same map can be used both before and after a meridian flip without needing to rotate the camera's output image.
