Three hour expousure in H alpha last night. Here hot OB stars associations light up this molecular cloud, Cederblad 214. This is one of the largest molecular cloud complexes in the Milky Way. Stellar winds and supernovae driven shock fronts produced by the hot OB stars of the association have expanded an immense 200 light year diameter shell of molecular gas which contacts the surrounding cold molecular cloud.
Out last night (Saturday 19th) for about an hour, dew came in to visit. Took one hour combined images to take NGC 6960, using H-a filter, in Cygnus with my Orion 80ED on the G8 mount. Combined in MaxIm DL/CCD.
This is a one hour image composite, 60 x 1 min exposures thru the new Astro-Tech 6" Ritchey Chretien telescope mounted on the Vixen GPD. I expected more but when you go from 3" ED scope to a 6" RC detail needs longer exposures. However I did an automatic processing in AIP for Windows and then experimented with additional processing manually. I will need to get 3-5 hours exposure or more to get more detail. And experiment with AIP. And I used a diagonal which is a boo boo !
