Hi, so next month a comet will come to say hello and I was wondering if anyone has some insights into how to image a comet using LRGB and possibly NB imaging through my F5.5 APO. I understand that, with OSC cameras, one would do images in intervals and later combine them using either the comet or the stars as registration reference. I am not after doing an animation, just a nice, deep shot of the comet in front of the stars and ideally some interesting details in the tail (either broad- or narrowband data). My questions What might be a sensible exposure chain for that purpose using Mono cameras and filters? Something like LRGBLRGBLRGB using, say, 10sec exposures with 5min breaks in between? I would be worried that the relative movement of the comet makes it hard to get individual filters stacked cleanly for a given exposure time point. Any insights or pointers to useful tutorials would be appreciated! Cheers, Marc |

Thanks Marc for bringing this up. I am in the same boat trying to shoot the comet with ASI1600mm MONO. I think first I need to understand how to collect the data correctly. Then I could figure out the processing details later . |
