I took this several nights back. It is an hour total exposure time, with 8 minute subexposures. All shot at ISO 1600 using my CAnon 300D and my Orion 100mm F6 achromatic refractor. This region is known as the " Witch's Broom" or the "Finger of God" because of it's visual resemblance. It is the remains of the pressure wave from a long past supernova explosion of a nearby star.

I shot this image of the Lagoon and Trifid Nebula's using the Stellarvue Nighthawk II and my Canon DSLR. I do not remember the statistics, only that it was 6 minute subs at ISO 1600. It illustrates the wide field available with this scope, though there is some definite curvature towrds the extreme edges of the field. It is a FAST achro, after all.
Over the course of my birthday last week, I ended up with a new telescope. A very nice little Stellarvue Nighthawk II 80mm F6 refractor. It is not an Apo, but is a very, very good achromat with a hand figured lens. I shot this image of the Veil Nebula with it. It is 56 minutes total exposure time with 8 minute subs, using my Canon 300D at ISO 1600.

The madness continues... I shot the Lagoon again, only using the Orion 100mm F6 achro and my Canon DSLR. It is a stack of 5 six minute sub-exposures at 1600 iso, all autoguided by my little 80mm F5 and DSI Pro. The moon was out was really bright. It sort of washed out the image.
