I will have to retry this experiment in a different location. The objective was to take a photo of the stars within an urban environment. For the night sky, the exposure settings were ISO 6,400, f/2.8 and 20.0s. For the church itself, the exposure settings were ISO 100, f/2.8 and 0.4s.
The problem I encountered was all the nearby lights that were pointed at the lens would cause some severe glare, particularly at those settings.
