Messier 13 from my own „Sterntaucher“ observatory
My next project in 2019 was the globular cluster Messier 13 in the constellation Hercules.
Here is an overview of the used equipment and the exposure times:
Equipment | Telescope 1 | Telescope 2 |
Location and date | Krefeld, May 2019 | Krefeld, May 2019 |
Telescope/Lense | 10″ Newton ohne Namen | TSQ-65ED Apo |
Focal length [mm] | 1000 | 420 |
Focal ratio | 3.9 | 6.5 |
Mount | Skywatcher EQ8 | Skywatcher EQ8 |
Camera | Moravian G3 16200 FW | Moravian G2 8300 FW |
Autoguiding | DMK21 AU04 on TSQ-65ED | DMK21 AU04 on TSQ-65ED |
Filter | L | R:G:B |
Exposure time [min] | 420 | 170:180:130 |
Resolution | 1.23″/px | 2.63″/px |
Data calibration and registration and the final processing was done with PixInsight. The RGB Data was upscaled to the luminance data. The result was as follows:

The two highest redshift quasars [Flesh 2015] in the image are:
SDSS J164411.85+361404.7 z=3.20 magG=20.4 (Gaia DR2)
SDSS J164250.78+360531.7 z=3.16 magG=19.3 (Gaia DR2)
