IC2177 in Ha
With the moon causing problems, its time to break out the Ha filter again.
IC2177 Seagull Neb (which is confusing because TheSky is showing ANOTHER seagull Neb somewhere else). This target is really low, never rising more than 27-28 degrees above the UK horizon. A fair amout of noise in the larger version, but unsure if this was due to dodgy flats, the moon, or atmospheric interference.
