There do not appear to other versions on Astrobin. Apparently first observed on 9/25/2011.
From the
Isaac Newton Telescope Photometric Hα Survey of the Northern Galactic plane (IPHAS) PN Catalogue.
It is apparent 31 arcseconds long. Morphology is "Ba".
The morphology of Ba indicates Bipolar type a: one-sided enhancement/asymmetries.
I believe the imaging and spectroscopy was done at "SM" or San Pedro Martir 2 m.
Note below the size was based on a 120s H-alpha exposure on a 2m telescope.
This scope has 31,400 cm squared of surface area, compared to my C11 with 2,529 or about 8% mirror surface. But, I did expose for 6 hours versus the 2 minutes.
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
IN – INT 2.5 m
SM – San Pedro Martir 2 m
KP – KPNO 2 m
GC – Grantecan 10 m
OS – OSN 1.5 m
MS – ANU 2.3 m with DBS
WI – ANU 2.3 m with WiFeS
SA – SAAO 1.9 m
