Description

First attempt with Nikon 600mm + TC14 (giving a FL of 840mm) and ASI294 color. Manual focus is challenging and takes time to nail, but the quality of this lens is superb. I am happy with this first shot that also include NGC 5474 irregular dwarf galaxy with PGC 4545422 galaxy overlying it.
