I tried StarNet++ v.2.0 GUI version on windows 10 on Lenovo Legion 570i with Core i7 12700H and RTX3050Ti. Processing finished about 5 minutes with Finer tiles box checked. Oxygen III emission areas got clearer. Oxygen III emissions are at 496nm and 501nm in wavelength, and they show a bit bluish green color. All in all, this frame presented unusual view of the area around Coalsack Nebula.

Here is a frame taken without dual narrow band filter:

Equipment: Sigma 35mmF1.4 DG HSM Art, IDAS NB12 Dual Narrow Band Filter, and EOS R6-SP5, modified by Seo San on ZWO AM5 Equatorial Mount, autoguided with Fujinon 1:2.8/75mm C-Mount Lens, Pentax x2 Extender, ZWO ASI 120MM-mini, and PHD2 Guiding

Exposure: 16 times x 60 seconds, 16 x 240 sec, and 19 times x 900 - 1,800 seconds at ISO 6,400 and f/3.2

site: 2,430m above sea level at lat. 24 38 55 South and long. 70 16 52 West near Cerro Armazones Chile
SQML was 21.55 at the night. Ambient temperature was around 6 degrees Celsius or 43 degrees Fahrenheit.

This frame was a mixture of frames taken with and without dual narrow band filter. Density 50% of frame taken with clear filter was on frame taken with dual narrow band filter.

There exist many striae of dark or hydrogen-alpha clouds flowing in the same oblique direction, from east northeast to west southwest or vice versa against the galactic plane. Who know the reason or mechanism of the large structure. North is up, and east is to the left.

This frame was taken with clear filter without dual narrow band filter. Focus got off in longer exposure frames.

SQML was 21.55 at the night. Ambient temperature was around 6 degrees Celsius or 43 degrees Fahrenheit.

This frame was taken with dual narrow band filter, IDAS NB12, but the most importance is not with those hydrogen-alpha emissions.

Total exposure time was 10 hours. Data were acquired during four consecutive nights. I tried imaging through five consecutive nights, but the data acquired at first night were discarded due to rotation of ball mount a bit after the night. The frames were different in direction from others gathered at the other four nights. The rotation made it difficult for me to register them together.

The rotation was recorded in the frame containing bright meteor: www.flickr.com/photos/hiroc/53748460722
