Description

Not much on this one. From Vogel:

According to Tweedy and Kwitter, NII is stronger than HII with this PN, with some OIII being detectable. According to Frew 2013, NII is 6x stronger than HII.

There is a little O-III in here rendered with HOO pallet. [See the Blue in the histogram]

GENERAL NOTE ON ABELL (and other) PLANETARY NEBULA>>>>>>>>>>>>>

From Wikipedia:

The Abell Catalog of Planetary Nebulae was created in 1966 by George O. Abell and was composed of 86 entries thought to be planetary nebulae that were collected from discoveries, about half by Albert George Wilson and the rest by Abell, Robert George Harrington, and Rudolph Minkowski. All were discovered before August 1955 as part of the National Geographic Society – Palomar Observatory Sky Survey on photographic plates created with the 48-inch (1.2 m) Samuel Oschin telescope at Mount Palomar. Four were later rejected as not being planetaries: Abell 11 (reflection nebula), Abell 32 (red plate flaw), Abell 76 (ring galaxy PGC 85185), and Abell 85 (supernova remnant CTB 1 and noted as possibly such in Abell's 1966 paper). Another three were also not included in the Strasbourg-ESO Catalogue of Galactic Planetary Nebulae (SEC): Abell 9, Abell 17 (red plate flaw), and Abell 64. Planetaries on the list are best viewed with a large aperture telescope (e.g. 18-inch (0.46 m)) and an OIII filter.

It turns out to my surprise most of these are visible with my Stellarvue 130mm (5-inch) SVX.

Bottom line there are 79 imagable Abell Nebula of which I have imaged 45 (half-way point Feb 6 2012).

This is my collection:

Planetary Nebula (Abell)

These are sorted by number and behind the Abell's are other miscellaneous PNs that I have imaged... I have a list of the 100 brightest.

These are some useful Abell relevant sites:
