Description

While the main scope (Orion 250 F 3.9) was imagine the "eyes" galaxies in the Virgo cluster (ngc4438 and ngc 4435), the secondary scope (TS65 Flat) put on top of the Orion was imaging the same starfield. But as for the focal differnce and for the size of the camera sensor (Nikon d5300 agains QHY183) the TS65 was able to image the full Markarian Chain of galaxies.

It's a large and famous galaxies group in the Virgo constellation.

Stacking with DSS, processing with PS and artificial flat with Astroflat pro plugin.
