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

Nice image considering your absence from the hobby and a difficult target too
Well done and welcome back

Nice work Wayne. As is often said, itís nice to have good guiding numbers but itís better to have nice round stars and youíve definitely got them ! And at focal length of nearly 2 meters ! Keep them coming !

Thanks Martin and Ryan, yes i hope to have more time now for astrophotography, M27 is a particularly difficult target for my position in the back yard as there is only a 1 hour window of opportunity to image it in the gap between my house and a row of large palm trees in the neighbors yard.
