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

10 x 1min subs iso 1600
10 x 2min subs iso 1600
10 x 4min subs iso 1600

Scope: 12 inch Meade LX200 at f6.3 (alt/az de-rotated mount)
Camera: Sony Nex 5n DSLR (full spectrum modified)
Guiding: Off axis Orion starshoot autoguider with PHD2

Processing: DeepSkyStacker, Startools, gimp
