On 2/02/2014 it was a very nice day here for a change. The outside air temp during the day was 15 F! A warm spell. I decided to set up my 6" F5 Orion reflector and take a look at the Sun. I used a full aperture Baader film white light filter. Through a 26mm Plossel EP there were several sun spots visible with group 1967 the largest. I decided to image it. I used my Canon 600D at Newtonian focus. I took several images and number 19 turned out the best due to atmopheric turbulance. This image was at ISO 100 duration 1/2500 sec.
I decided to leave the scope set up as the forcast for that night was clear but very cold (-5 F). I resumed imaging again about 9PM CST. It was very cold. The first object that came into veiw that I could image was M45. I targeted it and set up the SSAG guiding. I captured 15 subs of 2 minutes each. These were at ISO 800. Canon 600D at Newtonian focus. Final image was processed with Photo Shop Elements 8 and Canon Digital Photo Professional. I had to toss about half the subs due to freaking sattelites going through the images! Must be a main highway up there for sattelites! Anyway here is the image.
Now M42 had moved into view. I moved the scope over to M42 and took a few test shots and got it centered. The mount is an old EQ-5 clone and does not have GoTo. It just has dual axis drives with a modified HC for ST4 guiding. I shot M42 for about 45 minutes. Same settings as for M45.
I looked around the sky and Jupiter caught my eye. I removed the Canon and replaced it with a Televue 2.5X barlow and my Logitech 300 webcam. This brought the 6" F5 reflector up to 1875mm focal length. I took several AVI's and stacked them using Astro Stack. Still have more to process but here is the first run.
I wish Jupiter had turned out better but it was so cold I didn't spend much time with focusing. I may have also gone to long on my AVI's and planet rotation messed up the stacking. Jupiter spins fast and you can only go for a couple of minutes on the AVI's. Also atmospheric turbulance was pretty bad that night.
I also have some images of B33 that I haven't processed yet. Something to do on these cold and dreary days.
