The first image is of the beautiful spiral, the Triangulum galaxy(M33), about 3mil lys away he used over three hours of Luminosity and 80 min Red, 80 min of Green and 80 min of Blue light taken in October 2017. He stacked the images in Pixnsight then processed in Pixnsight and Photoshop.
The next shot is of the Horsehead Nebula, also known as Barnard 33, which is much closer at about 15lys away from Earth and very difficult to see visually, especially here in New Jersey!
He use 4 hours of narrow band Ha light over many nights due to various weather conditions during November and December 2017. Vlad also used darks and flats as well, stacking it all together using Pixnsight and then processing it in Pixnsight and Photoshop.
And last but not least; he took this great shot of the even further away Coma Galaxy Cluster, at a mean distance of about 325 mil lys from Earth on January 26th, 2018. He using 3 hours of Luminosity staking with Pixnsight and processing with both Pixnsight and Photoshop.
This is impressive work Vlad, thank you for sharing!
