Hi folks,
Finally, after some cloudy nights and bright full Moon in the sky last weeks, I was lucky to go out for star hunting with a good friend on Friday and to pamper my new "baby" for the 2nd time. We spend almost 3-4 hours under a beautiful sky, before the Moon rises up and started to light up the whole scenery (67% waxing).
I shot less than 2 hrs in Cygnus to catch photons from NGC7000 and IC5070, aka The North America Nebula & The Pelican Nebula. Despite the few amount of integration, I'm really happy with that result and how well my gear are working. This 76EDPH is a great scope! And it's very satisfaying when everything works fine in astrophotography (polar alignement, autoguiding, focusing, image recording,...) :-)))))
All details in the description. Stacking and editing in PixInsight. Final touch-up in Photoshop.
Stay safe and healthy, guys.
Christophe
About Rev B :
While processing my image, I've found some tiny features that look nice even through an 76mm refractor. I've tried to enhance them a bit, compare side-by-side with DSS images and collect some infos here and there :
Herbig-Haro 651/652/653 : HH objects are bright patches of nebulosity associated with newborn stars. They are formed when narrow jets of partially ionised gas ejected by stars collide with nearby clouds of gas and dust at several hundred kilometres per second. There are plenty of HH objects in Cygnus. I've picked up this group located in the "Gulf of Mexico" ;-)
GAL 084.0+00.8 : An area of ionized hydrogen associated with stellar formation. Looks pretty nice despite the small resolution of my image. Found on Simbad a paper from Felix J. Lockman "A Survey of Radio H II Regions in the Northern Sky" published in 1989.
Description: A funny attempt to catch some small features in Cygnus while processing this wide field.
