Spring is the optimum time to observe this beautiful edge-on spiral galaxy. It is situated approximately 40m light-years from our Milky Way and measures 100,000 light-years from end to end. This evening the sky was remarkably transparent and stable which gave good guiding and generally excellent image quality. It…

Imaged over the course of three nights where the seeing was the best for several months. M81 was high in the sky thus avoiding (though no totally) the negative effect of the ever-worsening light pollution. I included a lot of time on the Hydrogen Alpha channel to enhance the star-forming regions in the spiral…

Orion will soon be gone from the sky for another season. I wanted to have a new attempt to produce a satisfactory photogrpah of the bright star-forming region around the Trapezium in the Great Orion nebula which is so…
