Nicely done and processed. Very fine detail in the granulation.

And I can also see 2 small dark feature below it. Are those sunspots as well? Or dust?

Care to share how you process the image?

I think that 2 small spot are sunspot as well. Since it near to the main #1093 sunspot, thus counted as a group.

I just use Registax to do the stacking and PS for coloring.

You can see granulation of the sunspot really clearly in the picture above.

Does this mean that the CaK filter used on this scope has wavelength leakage? Or does this mean that the granulation extends up to the chromosphere?

Just curious. Will want to join you in one of your future sun observation.
