Description

A test with the purpose to create a "super" luminance. The image is an integration of narrowband images, Ha OIII and SII, into a luminance image A total of 78 sub exposures, 38*Ha, 15*OIII and 24*SII, approx 14 houres. In addition drizzle integration is used. The drizzel scales the image by 2. I think he drizzle gives the stars a more tight and natural look. The result an almost clean image. A very gentle small scale noise reduction has been done

The luminanse image is processed in Pixinsight, DB, Deconvolution, LinearMultiscaleTransform, MaskedStretched, curves and a contrast curve.

The luminanse is added to an RGB created by using SII for Red, Ha for Green and OIII for Blue at nonlinear stage.

Revision N is a combination of a starless version and the orignal where the prupose is to reduce the stars.
