Edmund/OFS filter stack for the 1010nm image, Astronomik 742, 10" f/5 GSO dob, DMK21 and ASI462. Winjupos simulation added for completeness. The dark patch near the limb, if it's a detection, might be Ovda Regio. Isthar Terra in the North (down) is even less obvious but there's a darker area near where it should be.
