That's excellent Bruce,
I've not heard of this pair, but you've presented them superbly. I just checked them out in Stellarium and perhaps one for me to consider as they would fit nicely on my QSI583 sensor through the C14 with Optec x0.7 tele-compressor.

NGC 4618 (left) and 4625 (right) are two single-armed Magellanic spiral galaxies, so-named because of their resemblance to the single-armed Large Magellanic Cloud. ?Their asymmetric appearance suggests a strong gravitational interaction between the two.
?But professional observations indicate the level of interaction has been modest, suggesting instead that the single-armed structures are created by processes intrinsic to each galaxy.
The image was captured during 4 nights in April 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 17.3 hours. Thanks for looking, Bruce W. |
