I could never have gotten near as much nebulosity without a filter from my location. This
shot was taken at F/6 with a TMB100 using an AP .75X reducer. I used an Astronomik CLS
clip-on filter (there are other filters just as good or better. This is just the one I
have) in a modded Canon XS at ISO1600. I was able to go 20 minutes on exposures, whereas
4 or 5 minutes was pushing it without one. This exposure is 5 hours and 10 minutes total
(10x15 minutes, 8x20 minutes).
