Description

I've always loved this galaxy and have been imaging it each year for the past four years. I started with a cheap 70-300mm achromat lens and a Sony dslr. I then upgraded to a Canon DSLR and an ED80 scope. Next came an ASI1600MM with the ED80. And finally, my 9.25HD with 1600MM. Each year has been quite the improvement in equipment and acquisition/processing. I feel it is always great to look back at what we have done and how far we have each come.
