A rare clear Sunday night, coupled with an even rarer Monday off gave me the opportunity to image M81, in the Constellation Ursa Major, also called Bode’s galaxy after Johann Elert Bode who discovered it in 1774. It is a grand design spiral galaxy about 12 million LY’s away, with a diameter of about 90,000 LY’s. I have imaged this object with a 10 inch Newtonian telescope and a DSLR back in 2016.
I imaged it last night through my 8 inch RC and the asi1600mm Pro monochrome camera using a Neodymium filter thats cuts out UV, and reduces star bloating. I captured 26 x 300 second exposures and processed them through Deepsky Stacker and Photoshop.
I then combined this image with the one from 2016 to produce a clearer colour image.
The Rosette nebula is now too low down now to image it until later in the year when it comes back round again, however the galaxy imaging season is here.
The Corona virus ( COVID 19 ) has finally had an effect on the astronomy community, the monthly meetings held by the Somerset Levels Stargazers has been cancelled until further notice, this is understandable as quite a large percentage of the members are of the older age group, I have no doubts that the meeting for the Crewkerne and district Astronomical Society will have a similar announcement very shortly. On a positive note the cancellation of so many international flights can only have a positive effect on climate change and hopefully produce some clear night skies.
