This GC is located on the outskirts of the constellation Lupus.
44 light frames at 30 second exposure each.
30 Dark frames.
30 Flat frames.
40 Bias frames.
Scope used: Skywatcher 102.
Camera is a Canon 1200D.
All stacked in DSS and post processed with Star tools.

Southern Pinwheel Galaxy. NGC 5236 or Messier 83.
This is a barred spiral galaxy that lies some 15 million light years from Earth.
It is found in the constellation Hydra and is one of the closest and brightest barred spiral galaxies in the night skies.
I used 124 light frames at 30 seconds exposure each.
30 dark frames.
30 flat frames.
30 bias frames.
All these were stacked in DSS and post processed in Star tools.
Scope used is my Skywatcher 102 and camera is a Canon 1200D.
I also did a crop of the galaxy.

May 1st 2016.
With some really nice skies for a change it was time to revisit a object I first captured back in March for the first time.
The skies were really nice and I also took out the 8" dob for a look at Mars.
Man it looked good in the 8" and 4mm EP.
Distinct surface markings were evident.
After that I surfed through some old favourites, it was great to have the dob out again!
Omega Centaurus.
From Wikipedia:
Omega Centauri (ω Cen), or NGC 5139, is a globular cluster in the constellation of Centaurus that was first identified as a non-stellar object by Edmond Halley in 1677. Located at a distance of 15,800 light-years (4,850 pc), it is the largest globular cluster in the Milky Way at a diameter of roughly 150 light-years. It is estimated to contain approximately 10 million stars and a total mass equivalent to 4 million solar masses.
Omega Centauri is so distinctive from the other galactic globular clusters that it is thought to have an alternate origin as the core remnant of a disrupted dwarf galaxy.
Scope- Skywatcher 102 ALT/AZ goto.
Camera- Canon 1200D.
I took 40 light frames at 30 second exposures and only 8 were usable.
Those 8 along with a few dark and flat frames went into DSS for stacking.
The post processing work was done in Star tools.
