Abstract:
We present the key results from an intensive and coordinated 10 year
observational amateur program designed to uncover and confirm Galactic
Planetary Nebulae (PNe). This has been undertaken and led by a
dedicated group of largely French amateur astronomers in collaboration
with professional colleagues. Over this period this group has
uncovered a total of 209 spectroscopically confirmed True, Likely and
Possible Galactic PNe with the work accelerating over the last 3 years
in particular. These new discoveries represents ∼5% of all 3831 True,
Likely and Possible Galactic PNe currently known according to the HASH
database as of March 2022. A further 610 PNe candidates are awaiting
follow-up. These figures demonstrate the power and value of the
amateur community in undertaking a coordinated and focused program
such as this. A dedicated on-line database has been created by this
group to record and present this work: www.planetarynebulae.net
Description:
Amateur and professional cooperation in the discovery, research and
analysis of planetary nebulae candidates. A total of 209
spectroscopically confirmed True, Likely and Possible Galactic PNe are
presented. For each PN usual names, PN G Galactic coordinates,
equatorial coordinates, angular size, details or origin of any spectra
and imaging are provided.

Our pro-amateur group was forged with time and perseverance to build a
team able to work together and bring the knowledge and competence of
each to this research field with the discovery and analysis of PN
candidates. The people involved are numerous and each one contributes,
according to their degree of involvement and know-how to the relevance
of the work and the reactivity that amateurs can show. QAP thanks the
Hong Kong Research Grants Council for General Research Fund research
support under grants 17326116 and 17300417. AR thanks HKU for the
provision of a postdoctoral fellowship. We would also like to thank
