The Sun with OIII Filter

This one was taken with (in addition to the normal glass filter) an OIII narrowband filter, which gives a nice turquoise colour. It also provides a nice contrast. This filters out all but a narrow band of emission light due to doubly ionised oxygen.

Skywatcher 8” Newtonian, 9.5” Seymour Solar white light glass filter, 1.5x Barlow lens with OIII narrowband filter, Nikon D3200.

Registax 6 and some contrast/saturation editing.
