George Abell published his catalog of Planetary Nebula in preliminary form in 1955 and in final form in 1966. The catalog contains "old" Planetary Nebula, of which half were discovered by Albert George Wilson and the other half by Robert G. Harrington,  Rudolph Minkowski, and George Abell on the plates of the first Palomar Observatory Sky Survey (POSS I).

The Observing Atlas comprises George Abell's complete catalog (except for the two known plate faults). Each PN is presented with two finder charts with fields of view of 25° and 5° to locate the field. A 30' x 30' DSS print allows to locate the planetary and to get an estimate of its apparent size.

Additionally, there are two close-ups of each planetary from the POSS II blue and red plates, which might be helpful to judge the visibility of the PN in the visible range. The relative spectral sensitivity of our eye compares roughly to that of the POSS II blue plates, which are most sensitive in the range from 450 to 550 nm, while the red plates are sensitive in the range from 620 to 700 nm (the emulsions used for the POSS I survey, on the other hand, had a quite different spectral sensitivity ranging from 350 to 500 nm and from 620 to 670 nm, respectively). 

The comparison between POSS blue and red plates may give you a hint to the degree of excitation of the gas shells of the planetaries. The OIII lines of doubly ionized oxygen are at 501nm and 496nm (with only about a third of the intensity of the 501nm line), while the HII lines of ionized hydrogen are at 656nm for H-alpha and 486nm for H-beta (which carries again only one third of the intensity of the H-alpha line). If a PN is visible primarily on the blue plates, it will likely be an object for the OIII filter. If it is much brighter on the red plates, this may be due to its emission in H-alpha and therefore indicate a considerable line strength in HII. As this implies as well emission in H-beta, a UHC filter that does include the H-beta line as well, might be the filter of choice.

Note that some PN have their strongest emission in NII (655nm and 658nm). In those cases, a "bright" appearance on the red plates does not necessarily imply strong HII emission (in that case H-alpha at 656nm)! As most astro-imaging H-alpha filters (with the exemption of the very narrow 3nm filters) transmit not only H-alpha, but as well both NII lines, even most "H-alpha" images do not distinguish between HII and NII. For these planetaries, the OIII filter may be the filter of choice, even that the planetary appears deeply red on images.  For further information see also here.

DSS 12'x12'

Abell 11 in Orion

05 37 22.1 +08 15 37

This is very likely a misclassification and rather a reflection nebula, as it shows no emission lines.

Nothing visible at 350x.

DSS 12'x12'

Abell 12 in Orion

06 02 20.0 +09 39 15

With OIII filter at 500x, it takes some time until the PN can be discerned for the first time. After that, it is a relatively easy object and appears as a small disk in the glare of µ Ori.

Carsten Dosche

DSS 12'x12'

Abell 13 in Orion

06 04 47.8 +03 56 36

Despite that the red color is intriguing,  this PN is strongest in NII and not in HII. According to Frew 2013 the ratio is 3.5.

For visual observers, it is therefore not necessarily an H-beta object.

This is likely a plate fault on a POSS I red plate. Nothing is visible on the corresponding POSS I blue plate, which was exposed 60 minutes earlier or on plates of later surveys.

Surprisingly, you  may find positive observing reports ...

Abell 18 in Monoceros

Abell 24 in Canis Minor

07 51 39.3 +03 00 29

This is again one of these funny red nebula that should respond well to H beta, but don't. According to Madsen et al., the red color is not due to to HII, but NII, which is about 5 times stronger than H-alpha and 7 times stronger than OIII. This makes OIII the strongest visual line, even that it doesn't look like this.

Nevertheless, even with OIII filter, the PN appears extremely faint, round and featureless.

Abell 29 in Pyxis

08 40 17.0 -20 54 14

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.

DSS 18'x18'

Abell 30 in Cancer

Abell 31 in Cancer

This is the largest Abell PN with a size of 17'x16' (of which, however, only the central part is visible) !

With OIII filter at 100x, Abell 31 is a relatively easy object and appears diffuse with no distinct boundaries. Internal structure is suspected but difficult to pin down.

Abell 33 in Hydra

09 39 09.1 -02 48 32

With OIII filter at 200x, this is a beautiful and perfect PN with distinct disk next to star. Darker center suspected. Well defined NW edge, lesser defined towards SE, appears therefore a bit oval. A bit less distinct with UHC.

This is the second largest entry in the Abell catalog with 16'x11', of which again only the central part is visible. Abell 35 is possibly a Strömgren sphere and not a true PN (Frew, thesis).

With OIII Filter, this object is immediately there as a diffuse patch around a group of three stars. The band structure in the S part was suspected. Distance of this object is about 500 LYs.

Abell 43 in Ophiuchus

17 53 32.2 +10 37 25

With OIII filter at 200x, Abell 43 is an easy object and appears as a filled disk with superimposed stars. Not anular. Can also be discerned without filter. There are hints to internal structure, which is, however, difficult to verify due to the superimposed small stars.
