Description

This image was taken using an Astronomik CLS clip filter with my Canon 600D (T3i) + Nikkor ED180mm manual prime lens on a tracking but unguided NEQ6 mount. Using the CLS filter resulted in lots of red star halos. Processing steps to remove them were to separate out the red channel then use a star mask and star size reduction tool to lessen their impact before recombining with the green and blue channels to create the final image.

Vers B - used PS HLVG plug-in to remove the greenish cast
