As always another excellent article. Did I miss the PDF?
Thanks for Small Wonders and look forward to many more.

Nicely done. As you know, PN's are high on my priority list. NGC246 is one of the better ones this time of year. You are right about the "small cluster" making it easy to overlook it. I spent quite a while looking for it one night with the 6" Newt. and after 1 frustrating hour, I realized I had passed right over it numerous times.
I'll have to see if I can spot the Hickson group next time I get out (if the snow ever stops here in Michigan!)

Just a note on the Packman nebula: I thaught the Packman was NGC 281 in Cassiopeia?

There's multiple Pacman nebulae.
I've always heard this one called "the skull", but O'Meara calls it the pacman in one of his books.

Thanks Olivier.

I've always heard this one called "the skull", but O'Meara calls it the pacman in one of his books.
I too have heard NGC 281 in Cassiopeia most commonly called "the Pac Man Nebula", as it shows the notable "mouth" gap in its southwestern side while NGC 246 is more of a complete disk. NGC 246 is one planetary which is really helped by the OIII filter, as the inner scalloped dark detail really comes out when using that filter.
On M77, one detail which is rarely mentioned is the very faint outer "ring" (actually two very dim spiral arms which almost merge), which is roughly three arc minutes out from the bright almost stellar nucleus of the galaxy. The usual bright main section of the galaxy is only about two arc minutes in diameter, but the outer faint ring is probably at least six arc minutes across. I have just barely glimpsed it in my 9.25 inch SCT, although it should be somewhat easier in a larger aperture. Clear skies to you.
