50 minute exposure, E200 film pushed 2 stops, tokai light pollution filter.
90 minute exposure, E200 film pushed 3 stops, tokai light pollution filter.
Note that the 50min exp is not focused, these details were scanned at 2700dpi from the slides, they represent about an area 5mm wide on the slide. Both images were adjusted to have an equal background brightness and color balance. They are both lousy images.
