The images were taken with the following equipment:
|Location||Rowe, New Mexico|
|Focal length [mm]||530|
|Exposure time [min]||105:140:120|
Data calibration and registration and the final processing was done with PixInsight. The result was as follows:
The faintest star in this image has an apparent magnitude of 21.5 magG (DSSR 15).
The three highest redshift quasars [Flesh 2015] in the image are:
SDSS J171822.76+423945.2 z=2.90 magG=21.2
VPM J17160+4330 2=2.90 magG=19.8
VPM J17197+4309 z=3.20 magG=19.2
