As it has a PN G Number - the G, incidentally, standing for Galactic, agree with this idea.

Hope that explains it.

Silly me, I should have known because of its size.
The planetry is one of the closest to us? Talk about lackluster.
Has anyone found a way to search to see if hubble has taken a photo of it?

Hubble has, but it is not that much chop!

Hi Enchilada & All,

Okay, well I'm more than moderately surprised to be reporting a visual observation of K 1-27 -- particularly as Kent had failed with it. What's more I have two other observers who confirmed it. I found it was best observed sans filter -- the OIII and UHC killed it. The conditions at Bargo were quite good for there last night (I just got home 20 mins ago).

At about 10.30pm just before the observation was made I took three SQM readings of 21.46, 21.44 and 21.43 which when averaged come out at 21.44(as near as makes no difference) and a ZLM of 6.36.

I located the field easily using the Argonavis and did a local sync on the nearby LMC O.C NGC 2203 one field away. There is a distinctive curl of four stars near the PNe, mags 12, 11, 11, & 10 N-S about 6-odd arc-mins long. The PNe is a little offset but basically between the southernmost two stars that are third and first brightest of the four. I found x247 worked best, with x317 being a little soft in the average seeing.

The PNn is said to be at about mag 16.5 according to the A2 but seems a fraction brighter than this visually and can be held steadily with A.V. After looking at this star for just 10-odd seconds I could intermittently see a small halo around it about 30" diameter. Difficult certainly, but not extraordinarily so.

Confirmed by Gary Mitchell and Andrew Hincks using my 46cm. We also looked with Gary's 50cm and he also independently confirmed that filtration kills it.

Hope this helps. Frankly I'm a bit flummoxed 'cos I was expecting to report a negative.


Best,

Les D
