Astronomy and Astrophotography by Michael Booth. I live in the south of Tasmania and in the breaks between the cloudy days and nights I like to get outside and enjoy observing and photographing the night sky.

Great Orion Nebula and the adjacent Running Man, NGC1980 and NGC1975) taken the night of the 11th December with one of my old trusty gold skywatcher ed80 Pro doublets with an Orion 0.80 focal reducer, UVIRcut Filter and a SVBony 405CC OSC Camera. This particular night I was using a HEQ5 mount ex Peter Sayers, ex ex Katina Edmunds. Once I get some clear nights to really establish its guiding performance (this night around 1 to 2 arcsecond variance) I plan to do a belt mod. I was also using 'in anger' for the first time, a mini PC with Nina, PHD2 and Carte Du Ciel to polar align, auto focus(with a Gemini Focuser), guide and capture. Studying and Learning from Cuiv The Lazy Geek's Video on how to remotely access a Mini PC via it's wifi hotspot from a nearby computer made removing a direct cable direct connection to the telescope possible. This will be handy for those sessions where I might like to sit inside in the warm just like you can with an ASIair setup. Why do this when I already have multiple ASIairs? Well just because I can? The image comprises 20 x 2 minutes frames and 20 x 0.5 second frames for the core around the Trapezium Stars, Processed and combined in Pixinsight and then further enhanced in Photoshop and Photoshop Raw. I am quite happy with the response of the colours and PixInsight's ability to hone in and enhance these mainly using the Curves Transformation function. Also I used the Local Histogram Equalization Function to further enhance the colour contrast.
