Combination of 2, 3 minute exposures, Meade 416XTE CCD.
300mm f/6 newtonian at prime focus.
HaTr 6 is a fairly small, and faint planetary nebula in Pavo, about 5 degrees east of the 3rd magnitude star delta ara. It was not visible in a 12" telescope, even when an OIII filter was used to dim the 7th magnitude star just to the east. Probably a 20" telescope would be required.
