M27 dumbbell Nebula
It has been around 2 years since my last effort at imaging, i almost forgot how to do the
setup for astrophotography and image processing.
The guiding graph looked like a tour de france mountain elevation map so many steep ups
and downs i was not sure if it would work, i keep getting calibration error warnings and
total RMS error reading was high at 1.2 to 2.8
