Description

Dumbbell Nebula last night from Phillip Island (29 degrees above horizon). Skywatcher 200mm/f5 and ZWO ASI224mc (100 exposures at 15 seconds = 25 minutes exposure; Gain 270). Ran out of time on this one as it disappeared behind the eaves after just 25 minutes. Dark and Bias frame corrected - but still sorting out how to take flats (it shows around the edges!). Think I also need an IR-cut filter to rein in the star bloat (if that's what is causing it) which is common to the ASI224mc, as it is apparently very sensitive to IR wavelengths. Alternatively it could be my post-processing.
