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.
Did you know my homepage and the English written Abell project?
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
