DrSti 1, PN-G 125.1-09.1

Co find by Marcel Drechsler (Germany) and Mark Stiles (US)

Year of discovery: 2019


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

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



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.
