A busy night

The great thing about long clear winter nights is that there’s so much time for imaging! These are three targets that were captured during one such evening recently:

NGC891

An edge-on spiral galaxy in Andromeda, 21 x 5min frames.

NGC1333

A reflection nebula, with a bit of emission thrown in, in the Perseus molecular cloud.┬áThere’s a lot of dark, dusty stuff in there, but my skies aren’t really dark enough to pick it up properly. However, you can “see” it by the relative absence of stars around the nebula. 21 x 10min frames

Comet 38/P Stephan-Oterma

And finally 8 x 5min frames, aligned on the comet nucleus, which diplay its movement through the stars of Gemini.

First light…

for an Atik 460ex OSC. I ‘ve tried LRGB imaging with the monochrome 314L+, but been generaly dissatisfied with the results; bloated star images through the blue filter, difficult to get good alignment of the different colour frames. So I’ve plumped for a one-shot colour camera. These images, taken last Friday (7 Sep) are my first attempts. The camera itself has worked very well, but I think I still have a lot to learn about theprocessing, particularly with regard to getting good colour saturation. All were taken through the MN190.

First up is M13, the great globular cluster in Hercules. This is a stack of 12 x 5min exposures.

Next is planetary nebula M27 in Vulpecula, also known as the Dumbbell nebula. This is comprised of 24 x 5 min exposures.

Then there was the Double Cluster, NGC 869 and NGC 884 in Perseus; a stack of 25 x 30sec frames.

Next up was NGC 891, an edge-on spiral galaxy in Andromeda; just 6 x 5min exposures.

And finally, the last quarter moon; 10 x 0.004s exposures:

An Edge-On Spiral

NGC891 in Andromeda is an edge-on spiral galaxy that looks much as our own Milky Way would probably look if you could see it from the same angle. This LRGB image was comprised of 20 x 3min luminance exposures and 20 x 1min (binned 2 x 2) for R, G and B taken through the ED80 with the Atik 314L+.
