Description:
Two bright but small galaxies are visible in the exepiece. Although the catalogues say that the face-on NGC 3738 is is almost 1 magnitude brighter than the nearly edge-on NGC 3756, visually the later one is clearly a lot brighter. The NGC 3738 is barely brightening near its core, and shows no star-like nucleus. The oval shaped NGC 3756 is almost perfectly even in brightness, displays no brighter parts. I notice that it's a bit asymmetric, the Western side of the ellipse is a bit flatter. SQM reading: 21.19,/arcsec2, 0°C (guess we're having a negative temperature record, where's the global warming?).
