A Comet, A Planet & A Nebula

It was a short night observing with the Society at Stargard on 17th January, due to the late sunset. Most of the attention was on Comet Lovejoy but I also caught a couple of shots of Jupiter and made my first hurried attempt at M42, The Great Orion Nebula, whilst in equatorial mode.

Position angle of ion tail=82° (re zenith=273°), Length of a 0.06AU long tail=3.7°, Position angle of dust trail (not tail)=147° (re zenith=339°), Orbit direction=61° (away from Earth), Latitude of Earth above orbit plane=-42°

M42, The Great Nebula in Orion:

2015-01-17 M42 1x30sec 1×10 sec 1x 5 sec f10 2000mm ISO2500DSS HDR PS

This is not a particularly good image of M42 but I hope to try and improve on it with more detail and accuracy, as it has shown me some potential for what I can do now that I have begun the process of converting my telescope to equatorial mode.
