Single strontium atoms held in optical tweezers have so far only been imagedusing the broad $^{1\hspace{-0.3ex}}S_0$-$^{1\hspace{-0.3ex}}P_1$ transition.For Yb, use of the narrow (183 kHz-wide)$^{1\hspace{-0.3ex}}S_0$-$^{3\hspace{-0.3ex}}P_1$ transition for simultaneousimaging and cooling has been demonstrated in tweezers with a magic wavelengthfor the imaging transition. We demonstrate high-fidelity imaging of single Sratoms using its even narrower (7.4 kHz-wide) $^{1\hspace{-0.3ex}}S_0$ -$^{3\hspace{-0.3ex}}P_1$ transition. The atoms are trapped in\textit{non}-magic-wavelength tweezers. We detect the photons scattered duringSisyphus cooling, thus keeping the atoms near the motional ground state of thetweezer throughout imaging. The fidelity of detection is 0.9991(4) with asurvival probability of 0.97(2). An atom in a tweezer can be held under imagingconditions for 79(3) seconds allowing for hundreds of images to be taken,limited mainly by background gas collisions. We detect atoms in an arrary of 36tweezers with 813.4-nm light and trap depths of 135(20) $\mu$K. This trap depthis three times shallower than typically used for imaging on the broad$^{1\hspace{-0.3ex}}S_0$ - $^{1\hspace{-0.3ex}}P_1$ transition. Narrow-lineimaging opens the possibility to even further reduce this trap depth, as longas all trap frequencies are kept larger than the imaging transition linewidth.Imaging using a narrow-linewidth transition in a non-magic-wavelength tweezeralso allows for selective imaging of a given tweezer. As a demonstration, weselectively image (hide) a single tweezer from the array. This provides auseful tool for quantum error correction protocols.
