Halley's Coronet consists of two interacting galaxies, NGC1532 is the larger edge on spiral galaxy that we can see in the image whilst NGC1531 is the smaller galaxy that looks like the turret on a gun ship. I don't know where the name Halley's Coronet comes from but to me the galaxy looks like the star ship enterprise (yes, I am a Star Trek fan ).
The galaxy is located in the constellation of Eridanus approximately 57.8 million light years from Earth. The two galaxies are engaged in an intergalactic dance with the gravitational pull of NGC1531 causing the distortions in the shape of the main galaxy. The interaction of these galaxies has caused a burst of star formation resulting in the bluish colouring that we can see in the outer spiral arms. A fascinating cosmic collaboration to be sure.
Love this shot Rodney, the hours spent in compiling this image has all been worth it and your careful processing has complimented it wonderfully. Soft and tasteful, without losing the fine details within NGC1532 and the many background galaxies which are accompanying it. The generated star spikes on the brighter stars also improve the overall presentation. Great job!
Great result Roddles. An incredible looking galaxy. I enjoyed zooming in to see the cool details..and...looking for worms (I..caaan..'t.. heee...lp...IT! )....buuut found none . You are certainly getting some really good results with your pretty modest gear mate, sign of a talented imager

Thank you kind sir. It is certainly a tad on the small size for my set up this galaxy but large enough for me to get away with it. I am both pleased and honored that everything looks ship shape . One of the good things about this forum is that there are some very critical (in a good way) eyes that can review the works offered and provide substantive and valuable feedback.

Thanks Michael, you are very kind. It does make for an interesting field with all of the stuff going on in addition to the complex shapes. I went the extra mile with the data acquisition as I planned to use drizzle integration knowing that I would have to crop down the field some. I find that it helps with the improved resolution. The star spikes are interesting in that they are not artificially generated even though I am using a refractor. My theory is that there are two possible effects that result in the diffraction spikes. One is a reflection in the imaging train and the other is as a result of the use of the masked stretch process in Pixinsight. Not that this is an issue as I have grown to like them actually.
Thanks again and let's look forward to some clear skies some time soon.
Nice image Rodney, the colour is really pleasing as too is the detail. I am working on this object too but need the sky to be clear around new moon to collect data.
Thanks for the positive comments everyone. I trust that the weather gods will be kind for this new moon Paul. This object should do well in your setup.
