My first attempt at doing 5 minute exposures, for the most part, did not go too well. I think mainly because of transparency issues. I had ran 4 minute long exposures the night before and they came out great. Those posts will be up as soon as I get the data totals on target that I want. However, my data on the Horsehead Nebula, in my mind, came out alright!

The two images at the top are my final edit / process. The ones here above are my first. I am including them because in someways they may be better plus I really like how the negative image looks.
