Christmas Tree cluster, Cone and the Rosette Nebulae
Images are reprocessed with my new method. This new technique will provide better color handling, softer look and high details at the same time.
Be sure to click the images to see them at a full glory.

This very seasonal closeup shows the Cone Nebula and a Christmas Tree Cluster around it.

Visual color compositions
Be sure to click the images to see them at a full glory.
Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission. This composition is very close to a visual spectrum.

INFO
In the constellation of Monoceros, just east of Orion, lies this huge nebulous duo with the famous Rosette Nebula at right and the Cone Nebula at left. The Rosette is easily recognized as a large flower to the left with bright central stars. In . The nebula on the left halves of the mosaic contains 'The Christmas Tree' star cluster in the center. The Cone Nebula lays at distance of ~2500 light years and the Rosette about a distance at 5200 light years.

This image shows the are with suppressed stars, the nebula itself stands out better by this way.

In the Cone Nebula and the Christmas Tree cluster photo, it kind of looks like a frog wearing a crown.
