Description: Kohteina oli Merakin suunnassa majailevat planetaarinen M97 ja galaksi M108. Piirroksen tein 32-kertaisella suurennuksella, jolloin kohteista oli mahdoton erottaa mitään yksityiskohtia. Ne näkyivät kuitenkin samassa kentässä, joka on kieltämättä ikuistamisen arvoinen asia. Molemmat kohteet erottuivat melko vaivatta, M97 oli tosin huomattavasti helpompi kuin M108.
