Description

I purchased some Astrodon O-III & S-II filters in July to compliment my 3nm Ha filter. I had been meaning to do this for a while but just got around to it. M17 was my first test with them. It isn't a lot of exposure time with only one 30 minute exposure for each channel, but it turned out rather well, so I kept it around for more than just test data.
