NGC 4145 - Spiral Galaxy

NGC 4145 (Canes Venatici) There is a discrepency between the planned target NGC 4145A with expected distance of 1.29 Gyr, z=0.0980 and this apparently larger (obviously much closer) NGC 4145 galaxy  lying at a distance of only 68 mly. The bright star on left edge of field is HIP 59366 (mag +6.85) The intended target NGC 4145A (alias UGC 7175, VV 814) is a different galaxy located 12 arc min away from NGC 4145 and is outside the field of view. The correct target to be rescheduled for a later session.  [ Distant Galaxies ]

Annotated CCD Image (50% size, square root scale) 2 x 180s exposure (average combine), 3x3 binning, C Filter 2021-01-18 02:52 UT (#851042-43) 12" LX200R (at f/10.4) + ST-10XME Auto-guided using TS 80mm APO, ZWO ASI178MC & PHD2

NGC 4145 -  Detail NGC 4145 appears to be nicely formed spiral galaxy but is poorly shown here due to sky conditions. Target to be rescheduled for a later session (see later images from following session S852 2021-01-19)
