C/2020 F3 (NEOWISE) 2020-Jul-11 Chris Schur

The comet is sinking lower in the eastern sky each morning, making it harder to get in a dark sky. Such are disadvantages of our southerly lattitude. The tail was seen while the head was in a cloud bank this morning, protruding about 15 degrees upward. Such an amazing sight. The gas tail is now separating from the dust as seen here, and the comet is requiring shorter and shorter focal lengths to fit in the field.

The image is my first attempt at getting the comets spectrum. Here, a 150mm f/2.8 macro lens was used with a 15 degree wedge prism on the front to get some nice spectral lines in this object. That was a 5 second exposure.
