Well, hard to believe I finally spent 30h on a target but here it is.  I think the inner ring is probably the H-alpha and O-III overlap most.

For those chasers of Hydrogen-alpha, here is a nice recent article: High-resolution Hα imaging of the northern Galactic plane and the IGAPS image database.

This is The definitive version from Doug. 80+ hours. 

From the Isaac Newton Telescope Photometric Hα Survey of the Northern Galactic plane (IPHAS) PN Catalogue.



This is also Object #6 in the IPHAS Catalogue and they come up with a diameter of 189 Arc" and a "Rar" morphology.  Was discovered on 9/23/2011.  S[ectroscopy was from the San Pedro Martir 2 m scope in Mexico.

Rar from the description below indicates R=round a= one-sided enhancement/asymmetries and r = well-defined ring structure or annulus.

Since I plan to image more of these (there are a lot) here is a table of descriptors from the original paper cited above and other sources.

Major and where relevant, minor axis dimensions in arcseconds: the measurement of PNe size was done from the 120 s exposure Hα images so we are limited in description of the exact extent of the nebulae.

Morphological classification: assigned following the ‘ERBIAS’ morphological classifiers to indicate Elliptical, Round, Bipolar, Irregular, Asymmetric or quasi-stellar (unresolved or barely resolved) PNe.

The additional sub-classifiers of ‘amprs’ were also used where evident:

one-sided enhancement/asymmetries denoted with ‘a’

multiple shells or external structure as ‘m’

point symmetry ‘p’

well-defined ring structure or annulus ‘r’

resolved, internal structure as ‘s’.

Telescope and date for first spectroscopic confirmation: a two-letter code is used to identify each telescope used for spectroscopic confirmations as follows:

WH – WHT 4.2 m

IN – INT 2.5 m

SM – San Pedro Martir 2 m

KP – KPNO 2 m

GC – Grantecan 10 m

OS – OSN 1.5 m (Observatorio de Sierra Nevada, Parque Natural de Sierra Nevada, Granada, Spain)

MS – ANU 2.3 m with DBS

WI – ANU 2.3 m with WiFeS

SA – SAAO 1.9 m

For those interested in these classifications there is another nice description around in the MASH Catalogue:
After review of the variety of then extant schemes previously developed, an adaptation of the current Corradi & Schwarz (1995, A&A, 293, 871) classification was employed, based in turn on that developed by Schwarz, Corradi & Stanghellini (1993, in Proc. IAU Symp. 155 on Planetary Nebulae, p. 214). The authors used a basic 'ERBIAS' classifier to indicate PNe which are Elliptical (oval), Round, Bipolar, Irregular, Asymmetric or quasi-Stellar (point sources). They made the added distinction between elliptical and purely round PNe on the basis of interest in these particular canonical Stromgren spheres, where an object is considered to be Round (circular) if the difference between estimated major and minor axis is < 5%. In uncertain cases a dual classification might be applied, such as E/B.The authors then added a sub-classifier 'amprs' which indicates that the main object has a one sided enhancement/asymmetry 'a', or has multiple shells or external structure 'm', or exhibits point symmetry 'p', or has a well defined ring structure or annulus 'r', or has resolved internal structure 's'. A morphological classification should normally have only one basic 'ERBIAS' classifier but can have several 'amprs' sub--classifications as the image resolution and clarity allows which are ordered alphabetically.
