We ask for valuable INTEGRAL time in order to augment our ongoing program aimed at creation of an ultra-deep extragalactic field in the direction centered on M81 galaxy. This ultra-deep field will become INTEGRALs legacy for studies of the AGN population at low X-ray fluxes and shall provide a ground for unique synergy with upcoming sensitive all-sky surveys by eROSITA and ART-XC telescopes on-board SRG observatory. We ask for additional 1.25 Ms of observations in AO17 aiming to increase the exposure for this field by 10 Ms till the completion of the SRGs 4-yr-long all-sky survey mission. [truncated!
