DescriptionA pair of dwarf galaxies in the Andromeda Group which I selected to include in the January CN EAA Challenge. I observed them on multiple nights, usually in less than perfect conditions, and found them surprisingly challenging to image. These observations were captured on my 3rd or 4th try.
