About this image

Imaged over four nights, 17^th 21^st 23^rd Jan21 and 3^rd Feb21.

Was trying to show the long tail of the “Hamburger” galaxy NGC 3628, could see it a bit but whilst processing to get the “black point” aesthetically pleasing the tail got lost – I will have to keep building on my data for this object.

This group of galaxies is approx 35 million Light yrs away, in constellation Leo.

Processing; Deep sky stacker, PixInsight with final tweaks in Photoshop and Topaz DeNoise.
