Here is the Rosette Nebula (Caldwell 49), an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula’s gas and dust. The Read More …

Here is NGC 2264, The Christmas Tree Cluster, in the constellation of Monoceros. The Christmas Tree Cluster is a young open cluster located in the constellation Monoceros. It is part of the NGC 2264 region, along with the Cone Nebula and the Fox Fur Nebula, and belongs to the Monoceros OB1 association, a loose association Read More …

Here is NGC 1499, otherwise known as the California Nebula. This is a narrowband shot, consisting of mostly Hydrogen Alpha and Sodium II wavelengths. The Oxygen III filter did not contribute much for this target. The California Nebula (NGC 1499/Sh2-220) is an emission nebula located in the constellation Perseus. It is so named because it Read More …

Here is a true color image of the Zeta Orionis region in the constellation of Orion. This rich area of the sky is loaded with deep sky objects. The central bright blue star is Alnitak, also known as Zeta Orionis. This is the lowest star in the Belt of Orion. To the left of Zeta Read More …

This is the North American Nebula, imaged with Narrowband filters, and rendered in the Hubble Palette. Although a false color image, this is the same color mapping that the Hubble Telescope uses to present its famous images. In this image, Hydrogen Alpha is presented as Green, Oxygen III is presented as Blue, and Sulfur II Read More …
