Citizen science search project for non-stellar emission line objects using online sky surveys to discover new Young Stellar Objects (YSO) Herbig-Haro Objects (HHOs) and Planetary Nebulae (PNe)
The night sky is vast, and not all objects of interest have been discovered. In this context, I am participating in a citizen science project to identify unknown Planetary Nebulae.
In the meantime, I have discovered 12 previously unknown Planetary Nebulae and two new Young Stellar Objects with a bipolar structure.
The discoveries are 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.
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.
If you are interested in a collaboration please get in touch with me.
Young Stellar Objects (YSO), Herbig-Haro Objects (HHOs)
0.3 arc min
Note: The main emission lines are typical for Herbig-Haro objects (HHOs). Further data are collected
Please take a look at this online article on planetarynebulae.net: Advanced image processing techniques to detect and identify faint PN candidates
Abstract: The following article describes the use of a advanced image processing methode to improve the visibility of faint objects, with a primary focus on planetary nebulae (PN),
based on optical surveys. The procedure removes stars from the image, leaving only the background and the object to be analyzed. By separating the stars from the images,
it is possible to control and manipulate the data more consciously and to concentrate on the essential in the image processing, object structures and their
morphology are more clearly identified, artifacts are excluded. More
