NGC 1333 Star Forming Region - Deep exposure by Eric Ganz, on Flickr

With a strong reflection nebula (blue) in the center, and weaker reddish brown and mixed tan emission nebula at the edges, this star forming region contains lots of dust and numerous new stars. Remarkable complexity is observed.
36 Herbig-Haro objects are also located here. These display unusual and interesting shapes, with characteristic red features. Zoom in to see these features in detail.

The central stars are dramatically lighting up the nebula.

Imaged from Deep Sky West - Rowe New Mexico, using RCOS 14.5” Ritchey–Chrétien telescope f/9. 3340 mm focal length.

L 16 hours exposure.
RGB 5:7:6 hours. 34 hours total exposure

SUN IN H-ALPHA
Through this image we can estimate the approximate measure of solar prominences and spiculaes. Note the greater prominence measured approximately 70,000 km.
The Earth has on average an average diameter of 12,756 km, so this prominence has a measurement larger than 5x the size of the earth.
I will show in other images the greater focus on the prominences and spicules visible on this globe, in later images.

A section of the Eastern Veil Nebula in Cygnus

Pictured is a portion of the Eastern Veil Nebula, NGC 6992, in Cygnus, which was discovered by William Herschel in 1784. The Veil Nebula is the result of a supernova explosion about 15,000 years ago and is approximately 2,500 light-years away. This bicolor narrowband image was taken through a Hydrogen-alpha filter and an Oxygen[III] filter, with the Red channel assigned to H-alpha, Green channel assigned to O[III], and the Blue channel assigned to 90% O[III]. The image was a total of 8 hrs 20 min exposure with a Takahashi CCA-250 f/5 astrograph and a QSIwsg CCD camera with Astrodon filters (H-alpha 5 nm; O[III] 3 nm) on a Paramount ME in Mayhill, NM on the nights of 17, 23, 24 October 2017 (O[III]: 16 x 1200 sec lights @ -20 degrees C; H-alpha 9 x 1200 sec lights @ -20 degrees C; 24 darks; 128 bias; 128 flats). Processed in PixInsight 1.8.5.1353 Ripley (x64).
