RCW 130-aka Sh2-10 in HaRGB

Sharpless Sh2-10 is an emission nebula located in the constellation of Scorpius. It’s very rarely imaged despite being, so to speak, in plain sight between two of the most popular targets in Scorpio-The Lobster (aka The War and Peace ) Nebula and The Cat’s Paw Nebula. It is quite faint but presents interesting structure even when imaged with a small telescope.

 

This image was constructed with four hours of Ha data acquired with a Sharpstar Z4. 2 hours of colour data was acquired with a William Optics RedCat51. Ha and RGB data was stacked in AstroPixelProcessor. and the stacked images were registered and aligned in APP.

 

The registered and aligned images were cropped and processed in PixInsight

 

after gradient extraction with the SetiAstro ADBE script, the RGB image was plate solved and Spectrophotometrically Colour Calibrated.

Blur X was NOT applied on RGB- it was found to create " worms" -artefacts after stretching.

 

Stars were removed with StarNet ++ and the starless image was stretched with GHS.

 

A similar process was followed for the Ha data except Blur X was run twice, SPCC was not used (obviously)

 

After GHS stretching Dark Structure Enhance and Local Histogram Equalisation processes were run

 

starless RGB and Ha were combined using the combine Ha with RGB script

 

The resultant image was blurred with light deconvolution and a LRGB image was constructed using the combine LRGB script

 

Stars were processed using the SetiAstro star stretch script and added to the starless image with Pixelmath
