Yes, very high magnification is required to tease out some detail in this wonderful little bi-polar PNe that really tolerates high magnification well, but only if the seeing is up to the job.

As luck would have it, I also spent about a 1/2 hour on it on Saturday night up at Mudgee where we had a very good sky transparency wise, but excellent seeing. I was able to use quite high magnification on Saturn (x371) with a pretty stable image and used x462 and x634 on NGC 5307.

I was able to repeat my earlier observation of it and saw slightly patchy and lumpy off-set "parentheses" with a lower surface brightness nebula between the them. Besides being simply a nice object, it was part of a talk I gave at the Mudgee star-party along observing notes on a collection of other bi-polar onjects -- many of which were PNe so I went and looked at all of them that I mentioned in my talk.

Three others also took a look and confirmed what I could see.

Still absolutely in love with NGC 5189 -- the most sensational PNe in the southern sky! Spent another 1/2 hr gawking at it too!

Oh ... and NGC 6445 wow!


Best,

Les D
Thanks Les
I am glad you too got some good observing in
NGC 5189 is a big favourite of mine
NGC 6455 is now on the list for future observation
Cheers
