Here’s the obligatory M45 image for the month of October, 2013. I shot this while waiting for other objects to get into position.
M4 and NGC 6144 are two globular cluster near the bright star, Antares in Scorpius. I shot this while waiting for Comet Pan-STARRS to come into view.
An easy to find open cluster that lies just below Sirius, the brightest star in our skies here in the northern hemisphere. I had just setup and needed something to test the rig and make sure everything was working. M41 was convenient so I shot 10 x 3 minute sub-images and combined those to get this final image. There was lots of moonlight and LP, so open and globular cluster shooting is about all you can do in such conditions.
I camped out on Friday night, April 19, 2013 at the old family farm property. I brought everything I needed to image with my Televue TV-85 APO refractor, including my Atlas EQ-G mount. What a load! lol I had fun even with a bright moon out. As soon as Omega Centauri was visible, I started imaging it. Three minutes at ISO 400 was as much as I could go with the moonlight and LP, so I tried to get as many sub-images as possible. I ended up with 42×3 min for a total of 2 hours and 6 minutes worth of integration.
I struck out trying to image Comet Panstarrs on Sunday evening, March 24, 2013. It was just too short of a time to find it in bright twilight, bright moonlight and with its low altitude. However, I tried something to redeem myself while I still had the equipment setup. I shot the Pleiades with a bunch of 15 second unguided exposures. I managed to catch them and Comet C/2012 L2 (Linear) in the shot. This is cropped down quite a bit to just the cluster and comet.
By the way, the comet is in the lower right. Its that small greenish smudge. 🙂

One of my better images of this rich Milky Way area containing the Trifid and Lagoon Nebulae. Shooting in the middle of summer is always tough, but I got a break when I took these some time in July of 2007.
Back when the southern sky was still dark enough to shoot long exposures, I managed to do 3 minute subs at F/2.8 and ISO 400 speeds. Taken sometime in July of 2007.
