Comet 38P along with comet 46P are both peaking this fall/winter. 38P will stay relatively dim, but at least it has a tail. This image of it was just a test of the Sony IMX224 on a half-decent comet.
I really wanted to shoot it with my DSLR and I was going to, but the weather changed abruptly Saturday night late and Sunday morning was clouded out. Heck, it even rained before sunrise. I had to tear down the rig before the comet was out with the fast change in weather. Darn the bad luck!
