Solar Features, High Res & FD | Sept 23rd 2019

Heya,

Woke up to a pleasantly clear sky and some ok seeing. Was able to get a little data at a few different scales.

I namely wanted to look at angular resolution differences between two wavelengths, in this case, 610nm and 430nm. 430nm has 41% higher angular resolution than 610nm. The difference is pretty close to comparing apertures of 150mm to 200mm in terms of resolving power, but also balancing angular resolution of the wavelength of light with it, so that they're similar.

Convection cells (150mm F16 at 430nm with 2.9um pixels):

Convection cells (200mm F10 at 610nm with 2.9um pixels):

High Res Spicules at the Limb (200mm aperture)

Prominences and chromosphere features (120mm aperture)

Full disc (52mm aperture)

Very best,

Love those convection cells!
