Description

9 July 2021. Messier 25, open cluster in Sagittarius. I only have a short time to observe this object as it is low in the south and due to the height of my observatory south wall and some trees. As Messier 25 is so low in the sky transparancy needs to be good, seeing is always rather bad. 20 images of 60s each were taken, calibrated and stacked with MaximDL 6. The FITS image was converted to TIF with FITSLiberator and processed in Photoshop CS5.
