Finally got some clear weather to image Comet Leonard again. It had been 20 days of clouds and poor conditions. A day or two before this night, it was announced that the comet was in outburst and had gotten significantly brighter. I was lucky to have the weather clear up just in time for me to catch it while it was still in outburst and displaying a dazzling tail!
Oh, here’s further work I did with those 15sec tripod mounted shots below. I was able to get 9 of the better ones to stack in IRIS and created this image showing the tail length better.
