This is a faint galaxy (surface brightness 14.4 mag/sq arc min) in Hydra.
Big one here
Wikipedia: The Galex ultraviolet image shows strong spiral arms and a central bar, but there is no nucleus. It is the smallest spiral in the local group.
Aspen CG16M on 20 inch PlaneWave on MI-760 mount. Luminance 14 x 30 mins unbinned. RGB: 90 mins each, 2x2 binned. Acquisition and processing all using our own in-house software. Seeing was 2.2 arc sec, ok for high summer at Euchareena.
At first glance, Big Blue here is the only galaxy in the image, but a deep surf through the original image shows two very nice pairs of interacting spirals, and quite a few very small and distant fellows also showing form, and typically a much more orange colour.
Really good to be back in the saddle.
