There do not appear to other versions on Astrobin. Apparently first observed on 9/20/2012.
Again did find O-III in the center of this one. The large foreground star made a mess of the PN colors so the cropped view is the NB colors enhanced with 3DLUT like the prior PN. You can see what the star does to the RGB in the published images.
Information for this image is from the
Isaac Newton Telescope Photometric Hα Survey of the Northern Galactic plane (IPHAS) PN Catalogue.
It is apparently 62 arcseconds across. Morphology is Round asymmetrical (Ra).
I believe the imaging and spectroscopy was done at "OSN" the 1.5 m Observatory of Sierra Nevada in Spain.
Note below the size was based on a 120s H-alpha exposure on a 2m telescope.
Published data:
Since I plan to image more of these (there are a lot) here is a table of descriptors from the original paper cited above.
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 Intermediate Dispersion Spectrograph (IDS) on the 2.5 m INT and the spectrograph ISIS on the 4.2 mWilliam Herschel Telescope (WHT) located at the Observatorio del Roque de los Muchachos on La Palma in the Canary Islands
IN – INT 2.5 m
SM – San Pedro Martir 2.0m Telescope (SPM) in Mexico with its Boller& Chivens (B&Ch) spectrograph.
KP – KPNO 2 m
GC – Grantecan 10 m
OS – OSN 1.5 m Observatory of Sierra Nevada (OSN) in Spain
MS – ANU 2.3 m with DBS
WI – ANU 2.3 m with WiFeS
SA – SAAO 1.9 m
