South Shore, Lake Ontario
I was observing from the South Shore of Lake Ontario in St. Catharines on this occasion. The wind was bitterly cold and from the north-west so it was difficult to look into the camera and telescope. The camera used was the Pentax MZ-7 SLR with Fujicolor 1600 film. The diffraction grating was inserted between the camera and back of the telescope to enable photographing of spectra.
All lights will seem somewhat duller than is normal due to their being seen through the grating.
The distant shoreline lights in the area of Mississauga were bright and obvious but very few in number, which was a bit odd. The pictures show duplicate lights as the mirage effect over the lake was producing doubles of everything.
The Toronto skyline was very clear and the grating provided spectra of the lights of the downtown area:
Here are some events taken with the Pentax attached to the Televue Pronto telescope. The film used is Fujicolor 1600. The orbs are in the lower part of the picture just above the real horizon. The upper part of the picture shows the spectra of the orbs. Spectra resolution is not of very good quality unfortunately.
