At 12' X 5' NGC 3621 in Hydra is a modest size SBcd spiral galaxy with very faint outer arms. It is about half the angular size of NGC 6744 in Pavo and at 22.3 mag/squ arc sec, has almost as low surface brightness, so it is a challenge to image well.
There are many background galaxies visible but the largest (still well under one arc min in size) and just above NGC 3621 in this framing, is the prominent 16th magnitude face on Sab spiral galaxy PGC 34490
Half the luminance was taken under reasonably good seeing conditions the other half under fairly average seeing and as usual no darks, no flats etc
