Description

M80 is a medium-sized (10') and bright (7.3 Mag) globular cluster located in the constellation Scorpius. The cluster is 33,000 ly away from the Earth, contains hundreds of thousands of stars, and ranks among the densest globular clusters in the Milky Way. The center of M80 has a very high capture and collision rate between stars. M80 hosts relatively many blue stragglers, stars that appear to be much younger than the cluster. On May 21, 1860, a nova was found in M80 that has +7.0 Mag.
This image was generated in June 2023 from backyard. Now, it was completely re-processed. This processing produced improvement. I kept original picture as the panel B. This image has SNR of only 15. 

Processing:
WBPP was used to calibrate, normalize and integrate Lights using for calibration Darks, Flats and Dark Flats. 
R, G, B and Lum were slightly cropped.
GraExpert applied for R, G, B and Lum. GraExpert produced improvement in cleaning background.   
RGB were combined.
DBE was applied
Conventional Color calibration was applied. 
Blur and Noise XT for RGB and Lum.  
Stretching required one application of mask generated in GAME script. 
Manual stretching for RGB and Lum were done using HT.
Noise XT, and then stretch again. 
Mask with Lum.
LHE was applied: 40 and 150 Kernes radius (setting 0.3).
MMT was not applied.
Curve was used for star saturation adjustments.
Blue and Yellow masks were used to enhance blue and reddish stars, respectively.
Mask with Lum was used for overall star saturation.
Annotation is the panel C
Main image is the panel D
Original image is on the Panel B.
