Hello Lawrence,


here is the more info of the SECGPN for the object at this location, from an extrafile I sent to Bill, some time ago:

Data concerning the central star:
B magnitude: 18.00
For UBV see photometric bands

Data concerning visual observations of the PN (a):
Steve Gottlieb's observation: successfully seen with a 13" telescope
Dr. Jack Marling's observation: successfully seen with a 17.5" telescope
Kent Wallace's observation: successfully seen with a 20" telescope

Miscellaneous data:

Sky Atlas 2000.0 Chart number: 01
Uranometria Chart number: 037
SECGPN finderchart page: 199


The Strasbourg-ESO Catalogue of Galactic Planetary Nebulae includes 1143
true and probable PNs; 347 objects which status is (1982) unclear were classified among
"possible" PNs, and 330 objects have been rejected.
The two latter categories are displayed by GUIDE in separated catalogues.
The designation system of the planetary nebulae of the SECGPN follows the structure
PN G111.1+22.2, where PN means "Planetary Nebula", G stands for Galactic Coordinates,
and 111.1+22.2 the galactic longitude and latitude respectively, truncated to one decimal place.


Some of the visual magnitudes were calculated by Dr. Jack Martling using spectroscopic data.
Most of the visual magnitudes were calculated by Owen Brazell using Dr. Marling's equation,
and are from O. Brazell's "A New Catalogue of Visual Magnitudes for Planetary Nebulae", Webb
Society Quartely Journal #104, April 1996.
Additional magnitudes were provided by David Frew.

I invariably use Guide as my arbiter of what does or does not exist. So what is
it showing in my image(s) at RA 01-53-04 dec +56-24-18? It looks like a
circular nebula but nothing is shown in Guide. Nothing is shown in the
corresponding DSS image.

Lawrence Harris
