Orionid Meteor Shower 2012






The 2012 Orionid meteor shower will peak this weekend! Fortunately, the waxing crescent moon will set way before the prime time hours for watching the Orionids. The chart at the top of this post shows the radiant point for the meteor shower, which is in the constellation Orion the Hunter.  The meteors will appear in all parts of the sky. But if you trace the paths of the meteors backwards, you’ll see they all seem to come from single point within Orion. Expect to see 30 meteors per hour.

My First Attempt at the Pleiades






This image was taken on 11th October using my canon 550d and 55-250mm lens set at 250mm. I stacked 8 JPEGs with 1 minute exposure each @ ISO 1600 and f/5.6, 7 darks and 10 flats. Actually I wanted to obtain more nebulosity but couldn't, may be because this image was taken from the city and one minute long subs are not enough to obtain nebulosity.

Andromeda Galaxy (first attempt)



This image was taken by me on the night of 7th October 2012 from a dark site a few kilometres north of Bhuj. The sky was very dark and I decided to travel with my friends carrying my camera and equatorial mount. The image was taken with Canon 550D and EQ5 mount ran by just a RA motor. As the mount was not very well polar aligned I could get short subs. I stacked 9 images with 2 minutes exposure each at ISO 800 and f/5.6. I used a 55-250mm Canon EF-S lens and set to 250mm. This is my first attempt of taking image of Messier 31. Hope to get better result next time.

JUPITER NEAR GIBBOUS MOON


Clicked this on 5th October 2012 when Jupiter was nearly a degree away from the Gibbous moon. I took two shots with different exposures using my Canon 550D and Sky-Watcher 4" f/5 refractor, and then merged them using photoshop CS5. The telescope was used with EQ5 mount and single axis motor to avoid trails. If you look carefully then you can easily see the four Galilean Satellites of Jupiter!

The Great Nebula in Orion!


I took this image on 26th September 2012 using my Canon dslr camera and EQ5 mount. After purchasing single axis motor (RA motor) for my mount this was the first opportunity to try capturing this beautiful nebula. This time my mount was perfectly polar aligned so I had no problem taking shots with longer unguided exposures. First I tried with 30 second exposures and then I kept increasing exposure timings and finally I could take 16 shots with 2 minute exposures out of which I stacked 12 JPEG frames in Deep Sky Stacker with 10 dark frames. This is my reprocessed image and I did a lot of work during post processing in CS5. My previous image is here.

I am quite satisfied with the result as this was taken from the city. Next time I want to try RAW images with even longer exposures and hope will get more better result :)
