Description

First attempt at the Rho Complex, very heavy light polluted part of the sky (facing south towards Toronto) and very low in the sky (max altitude I got was just under 20 degrees and the majority was taken just above 15 degrees). So not ideal conditions. Either way I am happy to say I captured something! Almost 3hrs worth, 90s subs with the RedCat 51 and ASI071 color camera.
