LRGB/HA/O3 with stretched flux added

PuWe1 (PNG 158.9 + 17.8), in Lynx

PuWe1 (PNG 158.9 + 17.8), in Lynx, is one of the largest PN, that has an apparent diameter of 20'. It has been discovered by Purgathofer & Weinberger in 1980 on a Palomar sky survey print.
As almost all this kind of old diluted PN, it is very faint and requires long exposures to get details. The Halpha signal is the strongest and draws a ring with several details in the structure while the OIII signal is extremely faint with a disc shape and no visible structure. I was looking for an outer halo that may have been possible in this object. From my observations I don't see any O3 data past the disk itself. In LRGB data it looks like the extended data is IFN flux nebula. Thanks Sakib Rasool for another fine target!
