NGC 5139

NGC 5139    Using short exposure astrophotography techniques.

I captured this image on the 13th January 2018.

The image consists of the following:

100 X 25 second exposures.
Darks and flats applied.
ISO 1600
Meade series 4000 UHC nebular filter.
Skywatcher 102.
Canon 1200D without any astro mods.
Raw files stacked with DSS and processed in PS and Star tools.

I did not get the object framed well and so it sits off center and I cropped the image some to compensate, NGC 5139 really deserves a nice wide field image so you can appreciate the size of this GC.

Anyhoo, here it is warts and all.
