THE ELUSIVE MESOSPHERE OF OUR SUN:
Have you heard of the solar mesosphere before ? the mesophere is a very thin layer of the sun atmosphere, located between the solar surface (photosphere) and the pink chromosphere. It is usually captured through flash spectrum where it shows up as a myriad of blue emission lines.
it is probably the first time the mesosphere is captured so clearly in regular imaging. Capturing the mesosphere requires both excellent resolution, and ultrashort exposure. I have captured it at the beginning of the totality, where it shows up as a very bright, blue layer at the bottom of the chromosphere. Even with 1/32000s of exposure and 64ISO, the mesophere was almost saturating the sensor.
Captured with Nikon Z8, 1/32000s, 64ISO, and 190mm diameter Maksutov Newton telescope.
