Here are my first tries at M51 and M13. The exposures were about 10 and 7 minutes respectively. Please excuse the dreadful scans - they are scans of prints, and they were made with the bad scanner on my printer. I don't even know how to do computer post-processing! I can't expose for more than 15 minutes from my backyard or else the negative will get completely fogged with the light pollution that plagues most of eastern Massachusetts. I am thinking about trying my red filter with these star clusters and galaxies- it wont work as well as it does with emission nebulae, but I have a book filled with black and white film photos of galaxies, and all were taken with a red filter. Unfortunately, there is still uneven fogging on my negatives; I am thinking that when I stored my bulk roll of film in the freezer after opening it, lots of moisture found its way into the emulsion. I am also entertaining the possibility that it is caused by poor storage after hypering, so I am planning on getting some nitrogen. If all else fails, I still have another 150ft bulk roll about 6 years newer than the one I'm using now.
