Subject: [QSI-CCD] Tadpole Galaxy image

This is an image of Arp 188, the Tadpole Galaxy, a highly distorted spiral galaxy in Draco about 400M light-years away. ?The striking "tail" is a stream of gas and new stars that is about 280K light-years long. ?This tail is believed to have been caused by a tidal interaction between Arp 188 and a smaller galaxy that closely approached it. ?This interloper galaxy can be seen shining through the disk of its larger companion - it's the small, oblate, blueish object at the 5:00 position relative to the center of Arp 188. ?Models show that this galaxy probably crossed in front of Arp 188, then orbited around it and now resides about 300K light-years behind it. ?The field is littered with very distant background galaxies, many of which appear distorted or interacting. ?A Hubble image of a small sky area immediately surrounding Arp 188 revealed over 6000 such galaxies.? The rendition shown here is heavily cropped in order to highlight some of the structural detail in the target.

The image was captured during 6 nights in June 2024 from SkyPi Remote Observatory using a 12.5" PlaneWave scope and a QSI-640ws camera at f/8 for a final LRGB integration of 16 hours.



Thanks for looking,
