DescriptionThese 14th magnitude galaxies are tiny and challenging in the best conditions; even more so with an 83% illuminated moon. This was early in our process, and obviously we did not give this enough integration time. I do intend to return to this target at some point, and would look to capture at least an hour with the mono camera, which at F/7 instead of f/10, would be the equivalent of 2-3 hours with the 294mc. That might not fully do it justice, but would be a HUGE improvement over what we see here. We've managed to save ourselves from utter embarrassment by converting the color image to black and white where we could push it harder.
