Widefield view of the Markarian Chain of Galaxies in Virgo.
4 hours of luminance only (12x20min).
Apogee U8300, Pentax 6x7 200mm lens.
Lens is wide open f/4. Focus was good, as evidenced by the dim stars,
but medium brightness stars are bloated, possibly due to chromatic aberration.
Still need to try stopping down to eliminate coma and bloating.
