Re NGC 2867, I took a good look at this last night out at Bargo and it is an impressive object with a strong cyan tint comparable to the Blue Planetary (NGC 3819) in Centaurus & a few others. Good conditions allowed me to apply a fair bit of magnification (with UHC & OIII x317, x371 & x464 -- though the latter was a bit soft looking) The inner disc seems about 12" diameter and round with a very hard edge to it. It dims weakly to centre but at centre (or nearly so) I suspect there is a very, very tiny (<1" dia) much darker hole or dot -- looking like a pin-hole. Surrounding the inner-disc is a thin very LSB outer halo only 10-15% larger than the inner halo -- say almost 15" diameter that is very tenuous. Beautiful field.

There is an HST image here:

Best,

Cheers Les thanks for posting your own observations of this object. This outer halo...is it best seen with or without an OIII filter?
