Herbig-Haro objects in the Pelican Nebula
Posted: Sat Aug 08, 2020 4:53 pm
Active region in the Pelican Nebula (IC 5070) in H-alpha, H-beta, O-III, N-II, and S-II with multiband filters
The Netherlands in Bortle 7/8
My first *real* DSO capture. Before this, captures of maybe 1 hour. This one is 5:20 hours in total.
And still without guiding
This is a part of the Pelican Nebula with star formation. It includes several Herbig-Haro (HH) objects of which HH 555 is the most prominent one.
An HH-object is a jet of particles and gas ejecting from forming stars. This with several hundreds of kilometres per hour.
In the top of the large, vertical dust pillar is an invisible forming star. But the jets are visible, in this case the small horizontal line.
Other HH-objects are there but not with such prominent outbursts.
Meade LX65 8" f/10 ACF OTA
Ioptron CEM25EC mount (no guiding)
Optolong L-Pro multiband filter
Optolong L-eNhance multiband filter
Zwo ASI294MC Pro camera
Captured with SharpCap Pro @ -10 graden Celsius / Offset 30 / White balance R50/B50
160 x 60 sec / Optolong L-Pro (over several night in between bands of clouds)
80 x 120 sec / Optolong L-eNhance
Stacked in DeepSkyStacker with 100 darks (experiment) + 100 flats + 100 dark flats for every set.
Stacked the L-Pro set, saved as FITS
Stacked the L-eNhance set, saved as FITS
Stacked the 2 saved FITS, saved as TIF
Processed in PS: Levels, Curves, Shadows/Highlights, color strengthening. Astronomy Tools actions: Contrast enhancement, noise reduction.
Copy/paste and black/white conversion including altering the color channels to grey.
Made composition, bit more noise reduction.
