UGC10214, The Tadpole Galaxy in Draco


(Click on image for full size version)


Description: Also known as Arp188, the tadpole galaxy is a small, faint but uniquely-shaped galaxy.  Whatever disturbed this galaxy left it streaming stars in a long tail to the east.  The Tadpole was imaged by the Hubble Space Telescope and the fully detailed image in all of its glory may be seen here.  This was an attempt to see what could be done by a small, ground-based telescope in a suburban setting without guiding.
Exposure Data: 3/28/2004.  LRGB: 50x3m, 10x3m, 10x3m, 10x3m. RGB binned 2x2.
-20C, 0.59 arc-sec./pixel.
Processing: Acquired via Sequencer II and CCDSoft, reduced, aligned and combined in Mira, L 30xRL, DDP in AIP4WIN, LRGB in Maxim, final combine, curves, levels and other processing in Photoshop.
Optical System: 14.5 Ritchey-Chretien RCOS Truss @ F/6.4, ST-10XME NABG/CFW-8A CCD camera, Paramount ME. AstroDon filters with IR-filtered L. Unguided and dithered 4 arc-sec.
Comments: Seeing was around 2.8 arc-sec and deconvolved to 1.9 arc-sec.  Maximum elevation was 67.  I suspect the improved efficiency of the blue AstroDon filter contributed to the detection of the tail.
