154P is pretty dim at the moment, a vis obs from Outbackmanyep last night at m1 = 12.7. Given that the obs encompassed a fairly extended object it is a very hard get. CCD obs are getting around 13s-14s. I imaged it (roughly!
) last night, no great shakes but it shows an extended greenish coma. Star trailing is due to movement of the comet over the exposure time - this was stacked on the comet head. C/2012 V2 (LINEAR) in morning skies is easily the brightest comet about at the moment (~mag 9). However moonlight is interfering. Err, and cloud if you live in my neck of the woods!
