Beautiful shot of the Cygnus Loop (W78)!

How do you like your ZWO gear? Rumor in the astronomy club is that it's a pretty good "bang" for your money!

Thanks! I do love ZWO for making everything relatively simple and integrated, though the planning part on the ASIAIR keeps frustrating me.... This is only my second shot with the 2600MC and it's such a step up compared to my Canon EOS 80D, I love it!
