A quick & dirty Whale and Hockey stick

Nights are getting shorter and shorter up here. So while I was waiting for ngc 2768 to pass the meridian, I pointed my scope towards the whale and hockey stick galaxies in Canes Venatici

This is only 1.5 hrs of RGB data (6 x 5 minutes exposures per filter). Not all satellite trails were caught by the rejection algorithm. I will revisit this pair once I'm finished with ngc 2768, and get more colour data as well as H-alpha. It would be nice to also catch the tidal streams coming from the whale galaxy. That is also the reason for the odd framing, one of the streams extends towards the lower left corner.
