deep sky

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.

Something I did long Time ago, one of the few RGB images I  tried with SXV-H9C
 

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.

Crescent nebula in Cygnus last night just past full moon. Two hour exposure (12 ten minutes exposures) tak toa 130 sxvh9 starlight express camera.

M106 0ne and one half hour exposure in one minute increments. Full moon rising. Closest Seyfert type galaxy with a black hole at the center and jets.

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 !
