I know this has been the subject of much joking and fun making at STO's expense over the technological mix-mash that coexists in this game. But just how striking it can be in contrast didn't really hit me until I was pulling into K7 station in my hybrid Galaxy class cruiser and saw these other ships sitting around me.
I took a screenshot as it just struck me as a wacky scene:
In this shot, my Galaxy hybrid is sitting next to a classic Constitution, an modern Excalibur, and some poor random Miranda that happened along. It just looks odd, but kinda cool in a time traveling kinda way :p
