Citizen science project for non-stellar emission line objects like Young Stellar Objects (YSO) Herbig-Haro Objects (HHOs) and Planetary Nebulae (PNe)



The cooperation between astronomers and amateurs offers innovation potential for research, in which ideas and impulses can flow into research and lead to new perspectives and questions.


Therefore, I am currently (04/2025) looking for partners and supporters, well equipped amateurs, astronomers with access to observatories.


Since 2023, we have discovered 15 new, previously unknown planetary nebulae, as well as 24 Young Stellar Objects (YSO), some with a bipolar structure. These are Herbig-Haro Objects. Further data still needs to be collected on some objects. Some of these objects have been registered in HASH PN database (Hong Kong University/Australian Astronomical Observatory/Strasbourg Observatory H-alpha Planetary Nebula Database). There is also an interaction with the Karl Schwarzschild Observatory in Tautenburg near Jena, Thuringia, and the Max Planck Institute for Astronomy, Heidelberg.


The new objects are a visual and photographic challenge for amateur astronomers. The sizes of compact nebulae vary between 10 and 30 arcseconds. The brightest candidates can be observed visually from 14", photographically from 8 inches aperture.
