Ngc247

It's been a few months since posting an image. Lots of cloud has stalled a number of projects. Some now have to wait until the coming apparition to be completed. This image is from the AG12 #2. I am now using an SBIG Aluma 694 with this scope. It still needs some tweaking to get things right but overall it is capable of producing an image now. It needs a lot more data but I have run out of time on it for this year and well I needed to process an image.

This image is of NGC247 which is located in the constellation of Cetus. It is a well known interesting looking galaxy and accompanied by several nice looking galaxies in the background. Some are quite distance and well red shifted. I counted quite a few of those. Feel free to have a count of the red shifted galaxies alone.

One thing I have noted though is that the filters or camera does not handle flares from stars just outside of the field of view all that well. I found that I was getting an annoying arc on the images. I'll let you find it, I have tried to disguise it but I am sure it can still be seen. I need to find the source of the flare though.

Image contains just under 8 hours of data, luminance which was only 135 minutes, Ha was 100 minutes and the rest shared by RGB.
