no-one else seems to have asked so i will- why the extra diffraction spike ? (the softer vertical one)

The ST-10XME has a microlens over each individual pixel designed to increase quantum efficiency. For scopes with f-ratios less than 7 (such as the BRC-250), this can show up as an extra vertical spike. SBIG has software that can remove the spike but it doesn't bother me.
