Description

M74 was easy to find tonight by lining up the Telrad with visible stars in Aries and Pisces. It was visible in my cameras with exposures of about 5 s or perhaps less. There are intermittent clouds tonight and gusty wind playing havoc with this image. I did go to 480 s subframes, significantly longer than I usually use. Bottom line: not enough time on target, too many clouds.
