Details:
Continuing my observations of the #AR2403 region on the #Sun: here is a set of images taken this morning with bad seeing (it was difficult even to focus).
The four versions are: B/W, False Colors, B/W inverted, False Colors Inverted. But, even if the seeing was bad there are some good details to put our focus on, like the region between the two cores, full of small structures and darker filaments!
The secondary core (the one towards the lower right portion) has increased in dimensions referring to yesterday, and the lower filament (here towards the upper right corner) is almost disappeared. On the contrary, the ones on the other part of the sunspot have indeed increased in number and darkness.
Instrumentation: SkyWatcher BlackDiamond Newton 200/1000 on EQ5 Motor - Astrosolar Filter - Barlow 3x COMA Apo/Apla - ASI 120 MM - 600 frames stacked on 6000. Elaborted with AS!2, Registax 6.1 and Photoshop CC.
