NGC 2867 etc

Hi PGC & Parkwood,

Re printed charts -- Nope, not nowadays only take the lappy & Megastar. With the DSS overlays from Realsky, I can't imagine a more detailed (portable) printed chart could exist.

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:
