Description

This is Arp 158 or ngc 523, which bears more than a passing likeness to ngc 520 in Pisces, also an Arp peculiar galaxy.

Pretty small, faint at mag. 13.5 and probably a very long way from here, there is not a lot to say about Arp 158. Haton Arp placed it in his 'disturbed with interior absorption'' class and declared the faint ESE extension to be the challenging feature. NGC 523 measures 2.5' x 0.7'.

The little edge-on galaxy lower right is ngc 512, mag. 13.7.

21 x 180 sec exposures through the 10" f4.8.
