Faint PN

[glenc]

Has anyone seen the faint (mag 11.7, size 215") PN Lo 5?
It was found in 1977 by Longmore at RA 11h 13m 51s, dec -48d 5.5m.
The image below is from the DSS 2 red survey.

Jenni Kay FRAS The following observations were made with a 12.5” f/5 Newtonian, form my semi-rural home site at Lobethal, SA. The skies here typically have a limiting naked-eye magnitude of 6.1, with the seeing rated at ANT II-III.

Longmore 5 : 11 13.9 –47 57 (Centaurus)
120X: Obvious enough, as a faint, large, round, hazy glow. Much improved with the UHC filter, showing a bright, doughnut shape, 3.5’ in diameter. 240X: Relatively bright annular, with a faint star at the centre, which may or may not be the true central star. Seems to be a little brighter along the western edge. 360X: There can be seen some six stars around the rim. Some catalogues place this planetary some 8.5’ too far south.

I will have a try for this object when we get a dark sky again.ARGO NAVIS data base give the coordinates as RA=11:13'50" DEC=48:05'29" still whithin the field of view of a widefield eyepiece from the coordinates given in your post
There are a few faint large Longmore Planetary Nebulae that can be seen whith medium to large sized amateur telescopes.

Here it is in Star Atlas pro, showing the FOV with by 10 inch, and 6 inch scopes.

The ESO Online Digitized Sky Survey
gives Lo5 = PNG 286.5+11.6 the coords
RA = 11:13:54.1 DEC = -47:57:00.6
It is 20' from the mag 6.5 star HD98022 in pa 265d.
