M 106

May - June 2012

Messier 106 is in Canes Venatici near the bowl of the Big Dipper.  I started this late in the season. Consequently I did not have enough time to get enough H alpha data or any color data.  Fortunately I some spectacular nights furnished me enough L data.  As a result I formed a "color" image by adding H data to the L data.  Thus we have white stars but the star forming regions are still highlighted.

Processing Details



The images were processed with PixInsight.  The H alpha signal was added to linear L data using the Vicent Peris Method.  The L data was then used for the G and B channels as well as L. The resulting RGB image was used as Chrominance to the original L image.
