As you all probably know by now, the 305 F3.8 Astrograph is in full production with prices listed on our website.

Bubblelicious

A short window of opportunity opened up last night for blowing some bubbles. I managed to obtain several 20 minute exposures. Here is preliminary result. It will obviously need 3 - 4 hours to get a smooth background. Maybe later in the week.

P.S for the sharp eyed, can you spot the camera defects in this image and identify where they came from?

M31, M32

Posted By Roland Christen
Last night was clear and good seeing. Had a 2 hour window of opportunity. M32 has such a large variation of brightness from the outer arms to the core that it is difficult to bring out detail over the whole galaxy. The exposures were limited to 60 seconds to prevent the core from burning out. The result shows the tiny star-like core with surrounding dust.

There was a fairly large gradient caused by the nearby gibbous Moon. Required a bit of processing in Photoshop.

AP 305F3.8 astrograph, SBIG-STL11K camera. Approximately 45 minutes total exposure, 60 second subs.

M33

It's finally clear and steady here in the Midwest. last two nights have been very nice for imaging, temperatures dropping down to 30F. A couple of images of my favorite fall objects.

Same equipment as M33. Exposures of 7 x 600 seconds. Lots of little galaxies sprinkled throughout the field.
