I had time for just a quick peek at Comet Johnson before moving on to my main target, Comet 45P.   It was not at an optimum spot and ISO 400 maxed out at 60 sec exposures with all the LP and moonlight.   So, it was not very deep and has noise and low color.  But, at least I can see that not much has changed since the last time I shot it.   This is supposed to be the next photogenic comet, coming this summer to a sky right above you.   🙂
