Description

This is a reprocessing of the image from 2019.

I always thought that my initial result was not giving justice to the amount of data collected.

I have reworked the HaLRGB from scratch now focusing on elimination of gradients and stretching to bring out dimmer parts of the nebula. Also I went a bit more aggressive on incorporating background Ha signal.

Now it looks more like a deeper representation of this beautiful area which hosts emission, reflection and dark nebulae.

Interestingly, being in a dusty region at low galactic altitude we still see a few external galaxies peeping through. I am showing a particularly tight group in the complementary image.

Acquisition times are:

Ha: 13.5 h

L: 6 h

RGB: 1.5 h each
