Granulation - Surface Texture

Post by Carbon60 » Mon Sep 24, 2018 6:11 pm

I managed a quick image of the sun this morning, capturing this 'granule texture'. Inverted view.

250mm RCT under less than ideal conditions.

Thanks for looking.

Looks good Stu...always a challenge in the near UV and poor seeing makes it worse.
