Annotated CCD Image (50% size, linear scale) 5 x 60s exposure (average combine), 3x3 binning, C Filter 2021-08-10 01:38 UT (#904024-28) 12" LX200R (at f/10.4) + ST-10XME Auto-guided using TS 80mm APO, ZWO ASI178MC & PHD2

Nova Cas 2021 / AT2021hkn - 2021-08-10 (T+144.6d) Image below (2021-08-10.066) was taken 144.6 days after discovery of Nova Nova is shown by white cross hairs.  Measured magnitude +8.16 Note: star object is saturated and shows some blooming, mag is probably underestimated (linked with Detection Threshold = 50)
