Abell (Planetary) 5 and 9

[FaintFuzzies]

Hey y'all,

Just wondering, anyone ever catch Abell 5 and 9? Those two are the only two in the Abell Planetary catalogue that I have never successfully observed. However, I have not attempted these two with anything larger than a 22".

I know that these two are probably not high in the sky at this season, but was looking back at my observing history and remembered that I am still missing these two.


Abell 5 (Perseus)
02h 52.2m, +50 36', mag >16, size 134x121"

Abell 9 (Auriga)
05h 29.0m, +36 02', mag >18.9p, size 40 x 34"

Note: Mag figures from Megastar.

Did you know my homepage and the English written Abell project (http://www.deepsky-visuell.de/Projekte/AbellPN_E.htm)?

To make it short. I could see a glimpse of Abell 5 but no any sign of Abell 9.

To make it more detailed:
Abell 5
16", 100x, [OIII], NELM 7m0
extremely difficult PN; after 30 minutes of observing I noticed a faint hint of light NE of the 14,1mag central star; somewhat elongated; unsure observation
27", 113x-172x, UHC, [OIII], NELM 6m5+
very difficult; with 113x and UHC a very faint disc is popping in and out of view around a central 14mag star; can not hold the glow steadily; with higher magnification (172x, 4mm EP) and [OIII] filter the round disc disappears and a faint laminar and somewhat elongated glow gets into the view directly SE of the star; not steadily visible and similar to the 16-inch observation an observation at the edge of visibility

Abell 9
14", 200x, [OIII], NELM 7m5
even under perfect skies not visible; difficult star field with many dangerous faint stars north of Messier 38; other observer also only suspected glow but could not hold or confirm the observation - negative result
16", 225-360x, [OIII], NELM 6m5
now with [OIII] filters from Lumicon and Astronomic - again nothing to see from the PN
16", 51x-225x, NELM 7m2
at the north edge of Messier 38; not visible without filter
27", 293x, [OIII], NELM 7m0+
only suspected; north of a faint double star, which is visible even through the filter; can not hold the glow; unsure observation - negative result

Hey Uwe,

I actually remember seeing it a while ago, but totally forgot about it. Thanks for the link.
