The invention relates to a power supply circuit of a low-light-level telescope. The power supply circuit comprises a voltage-stabilizing module, a voltage comparison module, a switch control module, a pulse generation module, a first MOS switch, a second MOS switch, a first voltage-division module and a second voltage-division module; the voltage-stabilizing module outputs a stable voltage entering the first voltage-division module; the voltage comparison module monitors whether the voltage reaches a certain voltage region and a certain boundary, and sends out a level conversion signal to the switch control module; the switch control module selects an OR gate to enter a low-power-consumption low-voltage reversely-connected protection circuit or selects the pulse generation module to enter a low-voltage prompt state and control a state of a light-emitting diode; the pulse generation module provides a light-emitting diode voltage when a low-voltage prompt is given; the first and second MOS switches control the
