Description

430nm has higher angular resolution than 610nm~656nm, so I wanted to show what could be obtained from a mere 80mm aperture refractor with short wavelength narrowband imaging of the photosphere to see convection cells in g-band wavelength. The resolution here is similar to what you would see with a 113mm aperture if using 610nm wavelength (red), but with a much smaller scope. Good to note out of interest for the upcoming Mercury transit for folk with smaller instruments who want to maximize what they can get, resolution wise.
