Sirius and the 'Pup'

About this image

I have been trying for most of the winter to find the right combination of camera sensitivity and image capture speed to capture the 'Pup' without Sirius A being so bright that I couldn't stack both in the image. For this I used planetary lucky imaging techniques and this is the best stack from a number of videos that evening.
