The comet 46P flyby which was to be the closest comet approach for years. This was occurring on the evening of the 16th of Dec and for the first time on about 2 months it was clear. The moon was fairly large on this day and the sky was a little washed out.
Initially the sky was clear and we setup cameras etc but soon after it started to cloud. after waiting for the cloud to clear it did indeed become very clear and the sky was very clear.
the below is a composite of 10 x 60s at ISO 1600 and 180mm using a Canon 6D and a Sigma 150-600mm lens. the images are dark, bias and flat corrected.
I have been trying a new processing method for the processing of the images. This was 3 hours of images from Manitoulin each of 10 min subs and processed against 15 x 10 min darks. The image was taken with the FLT 110 and guided. The image was processed by preprocessed by dark subtraction alignment and integration. The integrated image was then split into RGB channels and each was processed individually. Once desired levels were set the image was recombined.
Bubble nebulae 31 x 10 mins
So the weekend has been spent in manitoulin and basically turning nocturnal. Friday after the drive was supposedly going to be foggy and it was believed that the probability of of an imaging would be minimal. Instead the skies cleared and the night was very very long. Friday night i images 1 hour on the cocoon as an experiment to test against the longer imaging session, The Cave nebulae for 4 hours and 10 minutes of the 21P comet. Besides the CCD I have east mid and west Milky Way data, and data for this image. the region encompasses the M8 and M20 objects as well as Saturn in the image. Saturday night was a long night imaging just one object more on this once i have new dark calibration frames.
I have taken so many images of M31 this should be the last. This is a composite of only 8 x 2 min images taken at 105mm lens on the 6D. The Image is put together in Pixinsight. It is amazing how many stars there are in this location as well as the galaxy. the stars are very rarely visible in other images as the field of view is so narrow.
