Recent Observations: NGC772, the Fiddlehead Galaxy


NGC772 is a spiral galaxy which has one elongated spiral arm that leads to the informal name of "Fiddlehead Galaxy". It is believed to be twice as big as the Milky Way galaxy and 130 Million light years away. There is a second galaxy near NGC772 at roughly the 8 o'clock position which is believed to be the cause of the distorted spiral arm.


Here are a group of Fiddleheads for those who are not clear on what that is (from wikipedia, licensed under the Creative CommonsAttribution-Share Alike 4.0 International license).


This galaxy is in the constellation of Ares and extends 7 minutes of arc by 4 minutes, which is fairly small and makes it difficult to capture much detail without launching a telescope into space.




The image was captured at Lac Teeples on October 6 2021 using over 4 hours of data (stacking of 1 minute subframes). It was processed using 2X drizzling, doubling the resolution and giving a pixel scale of 0.62 arcseconds per pixel. RASA-11, ZWO ASI6200.
