UGCA 342 - Galaxy (PGC 46093), attempted observation

UGCA 342 (Canes Venatici)   R Mag of UGCA 342 from Simbad +18.55 Alias: PGC 46093 (Catalog mag ?) Image gathered under twilight conditions , Sun Alt -10.5°.  Limiting mag of image ~18.5.  No sign of any object at UGCA 342 (PGC 46093) location marked by white circle Other galaxies in view however are : M63 (catalog mag +8.5), PGC 2189676 (catalog mag +17.3), PGC 2191787 (catalog mag +17.7) Target location needs to checked :   Coordinates for UGCA 342 from Simbad are  RA: 13 15 07.535 Dec: +42 00 11.23 (J2000) Coordinates of PGC 46093 from TheSky6 are  RA: 13h 15m 08s Dec: +42°00'01" (J2000) Coordinates broadly match - the correct piece of sky has therefore been imaged. Target needs to rescheduled for much darker sky conditions.
