M51 – Box Brownie version!

Seeing  all the recent splendid images of M51 made me regret that I didn’t acquire some images of M51 when I had the chance last week!

So,I had to satisfy myself with re-processing images I acquired a couple of years ago using processing methods learned in the intervening time

This one therefore is a stack of 9X20-second images from 2015 and 25X20 second images from 2016 – 680 seconds in total.

The box-brownie snapshot version!
