Galactic field in Lacerta

[Dan_Paris]

Hi,

this small constellation at the edge of the Milky Way is seldom visited, nonetheless it contains many interesting objects, including small but beautiful galaxies and lot of IFN.

Here is a field containing the barred spiral galaxy NGC 7223, interacting with the elliptical PGC 214803 as well as the spiral galaxies UGC 11919 and UGC 11927. I took this picture last night with my 8" newtonian astrograph from my light-polluted backyard in Paris suburbs.

Thanks to rather good seeing conditions (2.1" FWHM after stacking), I managed to extract interesting details from these small objects (NGC 7223 is 1,4′ × 1,1′ only), even with my 750mm focal length.

 

First a crop centered on the main galaxies:

 

And the full picture, with several other galaxies and some traces of IFN in the upper part :

 

 

Thanks for looking,

Dan

omg doesnt a photo like this make us all look a bit small and insignificant within the universe?
