The $UBVRI$ CCD photometric data of open star cluster NGC 1513 are obtainedwith the 3.6-m Indo-Belgian Devasthal optical telescope (DOT). Analyses of theGAIA EDR3 astrometric data have identified 106 possible cluster members. Themean proper motion of the cluster is estimated as$\mu_{\alpha}Cos{\delta}=1.29\pm0.02$ and $\mu_{\delta}=-3.74\pm0.02$ masyr$^{-1}$. Estimated values of reddening $E(B-V)$ and distance to the NGC 1513are 0.65$\pm$0.03 mag and 1.33$\pm$0.1 kpc respectively. An age of $225\pm25$Myr is assigned to the cluster by comparing theoretical isochrones with deepobserved cluster sequence. Using observations taken with the 3.6-m DOT, valuesof distance and age of the galactic globular cluster NGC 4147 are estimated as$18.2\pm0.2$ Kpc and $14\pm2$ Gyr respectively. The optical observations ofplanetary transit around white dwarf WD1145+017 and $K$-band imaging ofstar-forming region Sharpless Sh 2-61 demonstrate observing capability of 3.6-mDOT. Optical and near-infrared observations of celestial objects and events arebeing carried out routinely with the 3.6-m DOT. They indicate that theperformance of the telescope is at par with those of other similar telescopeslocated elsewhere in the world. We therefore state that this observing facilityaugurs well for multi-wavelength astronomy including study of astrophysicaljets.
