Comet 46P/Wirtanen has been featuring in many astro photo's recently so it would be remiss of me to not share one of my attempts!

This is from last night 8th December. Three nights earlier I was in the WA Central Wheabelt under dark skies and the comet was naked eye when viewed with averted vision.

This was also a good test of my new ZWO 30mm guide scope and ZWO 290MC camera. Not the camera I intended to use with the guidescope but it seems my QHY QGuider has been outpaced by windows versions and no longer functional simply due to driver availability.
