Summary

Description
English: I capture the Whirlpool Galaxy every year hoping to do a little better job on it each time. But when I combined this year's data with last year, I had so many files because of my short exposures that it took me a full day just to calibrate and integrate them all - over 2,000 files. Here is more info on the hardware and software:
