Hi Chris , this is a report I did on the Ghost of Jupiter you may be interested in.
NGC 3242 Ghost of Jupiter (revisited)
30 mm plossl 60xmag very bright Azure slightly elongated ball.
30mm plossl with X 2.5 Barlow 152 x mag, Wow central star plainly seen and the duality of the nebula was seen giving one the impression
of an eye,with the exstensions plainly seen.
The O111 filter brightens the nebula so much that the double nature of the planetary almost disappears, the eye and central star is not seen.
Also same with the UHC.
17mm Nagler 107xmag Just stunning,so beautiful and crisp and bright,
I was blown away by how crisp the eye and exstensions where
THE 17mm gives the best view closely followed by the 30mm+2.5xBarlow
The filters where as above .
13mm nagler and 7mm where just to much power and so spoiled the impression
of the eye in the sky effect.
It was part of Suzy's May/June observation challange found
Here
Also Ngc 5307 found

I hope they are of interest and help
Cheers
