Bode's Nebulae, taken using FSQ-106/QSI 683 hosted by DSW. The original has some more information on the background, but not used, because I didn't see a good way to fit it in. Some efforts have been placed on NGC 3077, trying to reveal some detail, but anything strong affect the other two adversely. Was told not to use any manual drawing in the mask. Gave up.
