R Coronae Borealis

As there has only been one imaging night for the whole of October 2015 I have had to look for other things to get on with.

I took a Sky 90 image of the R Coronae Borealis (RCrB) region in August 2013 and again with the Canon EF 200mm DSLR lens in May 2015.  In August 2013 RCrB was at its minimum around mag 14 or 15, and in May 2015 it was around mag 7 to 8.  I put the two images together in an animation that you can see running here.
