Observation of UGC2496

DSS UGC2496 DSS UGC2496

DSS RealSky image of UGC2496 magnitude: 17.1 Spiral Galaxy (edge on) RA: 03h 02m 29.4s Dec: +4626'46" (Epoch 2000). Notice the other two galaxies top-left ( 2MASXi J0302392+462732 RA: 03h 02m 39.2s Dec: +4627'32" (Epoch 2000)) and top-right ( HFLLZOA G145.21-10.67 RA: 03h 02m 23.6s Dec: +4627'54" (Epoch 2000)). I used NASA/IPAC Extragalactic Database to identify these galaxies.

Cropped Fastar image of UGC2496 resmpled 2x to be closer to the DSS image scale to the left. This cropped image is located at the 2 o'clock position from NCG1169 and 40% from NGC1169 to the edge of the image. Star magnitudes reach 19.5 for the dim stars in the above cropped image.
