Description

This is a mosaic of two images of the Rosette Nebula.

The focal length of my Esprit 120ED at 863mm is too big to get a single full frame image of the Nebula. So I used Telescopius to set co-ordinates to image the top half and bottom half of the Nebula with a 15% overlap through the plan mode of my ASIair Pro.

After stacking in DSS I stitched with Image Composite Editor. In PixInsight I did some deconvolution and enhanced the luminous. After stretching I removed the stars with StarXterminator, then split the channels and created a new green channel with 60% red and 40% enhanced green and then combined them back together and brought out more colours with Curves Transformation and then added back the stars with Pixelmath.

I finalised th image in Photoshop and added some star spikes with Starspikes Pro 4.
