assembled NGC 40 in colour

Processed NGC 40, aka the Bow-Tie Nebula, in colour.

Followed Trevor Jones's general advice for making a HaRGB image. A handy tutorial on his AstroBackyard web site.

It worked. It boosted the red in the image, emphasising the bi-polar features of the planetary nebula.

Used the data from 8 Aug '16 and 14 Sep '17 to assemble the full colour image.

Prepared in Photoshop.


The red offset is a little off-putting... I'll have to employ a mask...
