This picture was taken arbitrarily in Canes, looking for a test object to verify the corrections I did to the optical train. In the previous image (M3) I noticed some tilted focal plane. That was due to an extension ring which was not tightened enough. The main galaxy here is NGC5353
This is a group of galaxies in Leo, the Lion constellation that dominates spring nights. M65, M66 and NGC3628. At distances of 35, 42 and 37 Million light years, they form a fysical group in space Tidal forces rip apart the extremities of NGC3628. The smallest galaxy identified in this image is PGC1423398 at a distance of 2 Billion light years: so glad those fotons travelled that distance in space & time only to get caught in my camera!!
Picture with: C11 Starizona LF SCT reducer F 7.2 FL2010mm Nikon D750 FF Optolong L-Pro 2″ 800iso 27x600s
This is a very familiar sight and thousands of pictures have been taken of this little “seahorse” or horsehead in the sky. Taken with the Celestron C11 on an EQ8 mount, Starizona LF corrector for Schmidt-Cassegrains, a Nikon D750 DSLR modified for extra H-Alfa sensitivity. 22 frames of 300 seconds each are combined in this image
