Krasnovsky

From Memory Alpha, the free Star Trek reference.

Captain Krasnovsky was a 23rd century Starfleet officer and starship commander.

In 2267, Krasnovsky's ship was put in at Starbase 11 when the USS Enterprise conducted its layover there. As a ranking officer, Krasnovsky served on the board conducting the court martial of a fellow captain, James T. Kirk, when Kirk was accused of the apparent death of Lieutenant Commander Benjamin Finney. (TOS: "Court Martial")

[edit] Background

Captain Krasnovsky, played by actor Bart Conrad, wore a blue sciences division dress uniform, making him the highest-ranking officer to appear wearing science division dress colors. All other science officers seen on Star Trek were commanders or below.

Krasnovsky was introduced as a "Star Captain." The only other starship commander to wear a blue uniform was Lieutenant Commander Jadzia Dax after being placed in command of the USS Defiant in 2374.
