I can state without reservation that this is the most beautiful and informative astronomy book I currently own, and I own quite a few! But, what are the Arps? In 1966 Halton Arp published an atlas of 338 “Peculiar Galaxies”, … Continue reading
The imaging object of the month for October is the mass of emission nebulosity near Deneb in the constellation Cygnus: NGC7000 the North America nebula, and IC5070 the accompanying Pelican nebula, are both very large and very bright Hydrogen alpha … Continue reading

The last RGB image of the Veil nebula has been significantly improved by adding some H-alpha and some OIII narrowband data as can be seen in the accompanying image. However, the project has turned into an even bigger undertaking. I … Continue reading
