We are coming into galaxy season now and one of the best examples this time of year is Markarian’s Chain in Virgo. Although imaging is straight-forward under dark skies, imaging from light those that are polluted can be challenging. I made this image using a Quadband Optolong filter attached to a QHY268C camera connected to a TAK FSQ106. The total integration was 8 hours. Some time ago, I tried the same experiment without the filter, to no avail.
