Notes: * This object (and Maffei II, currently in progress) has been difficult to image ... Maffei I was imaged during a mild off-shore (Santa Ana) event that made the seeing very poor, and the nearly full moon got close enough to cause very uneven filed illumination on the last day I imaged (11/5). Also, see Maffei II, imaged after Maffei I.

* Maffei I is listed as behind the Galactic (Open) Cluster Czernik 11, which I assume is the scattering of stars on and around the obvious nebulous object. See the CDS listing for "UGCA 34".
