Description

DrSti 1, PN-G 125.1-09.1

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

Year of discovery: 2019

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
