http://planetarynebulae.net/FR/page_np.php?id=683
Coordinates: 01:06:28.60 +53:40:52.30
Constellation Cassiopeia
Diameter: 5 arc minutes
Type: extremely faint, bubble-like planetary nebula with central white dwarf (CSPN), high amounts of HII, low amounts of OIII

Dr 36, PN-G 125.3-08.9
Year of discovery: 2019
http://planetarynebulae.net/FR/page_np.php?id=681
Coordinates: 01:07:40.04 +53:52:24.02
Constellation Cassiopeia
Diameter: 2.7 x 2.1 arc minutes
Type: faint, bubble-like planetary nebula with surrounding ISM and central white dwarf (CSPN), high proportions of HII, low proportions of OIII
CSNP:
Distance (average) 3653 light-years
proper motion of the star: pmra: 2,466 / pmdec -8,912 mas/yr
The high proper motion of the star explains that the CSNP is not in the center of the object.

i want to thank Chris Sullivan for "introducing" me to Marcel, and also thank you Marcel for the opportunity to image one of your new discoveries
who knew there'd be another one so close by :)
