I tried shooting some sub-images of Comet ISON on Saturday morning, Oct 12th, but the fog and murk near the horizon was too much and the comet was barely registering. So, I switched to Comet Lovejoy, which was much higher in the sky. With the dawn quickly approaching, I went with one minute exposures and managed to get 24 good ones before twilight put a stop to my efforts. Twenty-four subs gives me enough noise reduction to make it worth while.
This is a busy area in the Auriga constellation. M38 is an open cluster at the top of the frame. Beneath that is NGC 1907, another open cluster. To the right side is a faint nebula listed as LBN794 in Cartes du Ciel. At the bottom of the frame another patch of nebula known as IC 417/LBN804.
Edit: I managed to add 40×30 sec @ ISO 6400 sub-images to this and the above image has been updated. Below is the original details and image:
Here’s the obligatory M45 image for the month of October, 2013. I shot this while waiting for other objects to get into position.
Here is the October 2013 version of this photogenic area of the sky. I used a high ISO and lots of sub-images. Noise was low, which was good. Color was more difficult to deal with than a lower ISO stack normally is.
Just before dawn broke on Wednesday, October 9th, 2013 and put a stop to imaging the night sky, Comet Lovejoy cleared the trees in my backyard. I was able to get 20 minutes worth of data on it before the sub-images were too blue from the twilight to use for stacking.

It is somewhat unusual to have 3 relatively bright comets all in the morning sky at the same time. This one, I think, is the brightest and the other two, Comet Lovejoy and Comet ISON, are close behind. Anyway, I managed to get data on all three comet in two mornings of imaging. Its a comet hunter’s dream come true!
Here is my first Comet ISON image. It was low in the east in lots of light pollution, but I managed to get enough shots to make a reasonable image. I had to cut down a small tree the afternoon before taking this to get a clear shot.
This was taken with my TV 85 and a modified Canon T3. It is only 26×180 sec sub-images @ ISO 1600. I was just testing the scope, mount and computer to make sure it all still worked, since the last time I used it was last April.
A new film is out with the best high quality images available of Earth and Space taken by various space probes, professional observatories and amateurs. Maarten Roos, a planetary scientist, is the filmmaker and William Zeitler is the musical soundtrack composer.
Here’s a video excerpt from the DVD:
Below are a couple of stills from their website. The first image is a NASA/JPL image of Comet Hartley 2 from a spacecraft and the one below it, (by yours truly,) is an image from Earth.
Quote from their website:
“Do you look up on a clear night and gaze in wonder on the stars deep into the Universe? They provoke inspiration and awe, a moment of calm, quiet, and peace in our hectic world. Serene Universe combines the awe of the Universe with these healing moments of serenity. It is a unique one hour film experience in which images and music are intimately intertwined. Starting on our beautiful planet, Serene Universe takes you slowly above the Earth, into the Solar System, the Galaxy, Deep Space and finally your inner space.”
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.
