Messier 5 – First Color CCD Photo Ever
by Mike Hankey, under Stars
I had a good run on globular clusters during last month’s new moon phase that culminated with this color shot of M5. Note the faint green trail of a satellite in the upper left. The only reason its green is because I was shooting through a green filter when the satellite crossed the field of view.
I have been transitioning from DSLR astrophotography to CCD photography. The CCD cameras are way better and the quality and overall ease of things is much better, but there is a bit of a learning curve. I’m still working out some issues with the optics and guiding combos. This photo guided perfectly with the MOAG, but due to the way things are connected, I can’t use the field flattener / corrector when I’m using the MOAG. As a result, there is distortion and stretching at the outer corners. I have since setup a guide-scope, so I can use the corrector and I’m getting worse guide results now. So there’s still work to be done… All this aside, M5 turned out pretty good for the first attempt at a color shot and July is starting out nicely too.
