We have placed two PW Delta Rho 350 telescopes on one GM3000 mount from 10MICRON. Given the telescopes’ large focal ratio of f/3 this allows a quick generation of extremely deep photos. Here, too, we use two cameras QHY 600M Pro, cooled down to minus 10 degrees and using binning 2×2. For the creation of data CMOS LRGB, H-Alpha, OIII as S2 filters from Baader.
At every clear night with good or very good seeing we collect subframes with an exposure time between 0.5’ and 10’, depending on the brightness of the object. Our location south of 37 degrees northern latitude allows covering a significant number of interesting DSOs, many of them do not rise sufficiently in central Europe.
