I stand corrected. As you say the sunspot is twice refected so it can be used to determine index error in the same manner as a star or planet would be used.

Can you explain how the sunspot image appears in "reciprocal". Intition tells me this is wrong. The reflected image is twice reflected. Experience just now looking at my neighbors house tells me this is wrong.
