Hi guys
A mega project progress pic, dimish, not many amature pics I can find of this, annoyingly, again, not in the Sky X database. Click here for big (http://fredsastro.smugmug.com/Photography/Astrophotography-1/i-hsN5m5Q/A)
Taken on an RCOS 10" RC Scope at f9, SBIG STXL6303E Camera and PME mount at itelescopes Siding Spring Observatory.
Processed with CCDstack, Star Tools and Photoshop.
63 off 40min subs 3nm Ha 42hrs total exposure.
Taken over all November, much more OIII, SII and RGB taken I will add later.Its so much work, I thought I would post this in the mean time.
I agonised over the look, its not over processed, it is that narley.
Following description stolen from Don Goldman.
Henize 70 (N70, DEM L301) is part of the Large Magellanic Cloud in the southern constellation of Dorado about 170,000 light years distant. Henize 70 is a superbubble in which fast, energetic stellar winds from massive, hot stars (OB association LH 114) clear out a bubble from the surrounding interstellar medium. You can see a group of hot blue stars near the center of the bubble. The energy released into the bubble ionizes elements, such as hydrogen, oxygen and sulfur, and causes them to glow. It has also been suggested (Skelton et al., Pub Astro Soc Pac, III, 465-481, 1999) that supernova explosions within the last million years also contributed to the structure of the nebula. The nebula is about 300 light years across.
