    Hi,

 

NGC 7217 is  face-on spiral galaxy with a ring, about 50 millions l.y. away from us.

 

I imaged over two nights last week, using my 8" Newtonian with Romano Zen optics on an AP900 mount with an 183mm  camera, from my Bortle 7 backyard 20km from downtown Paris. I recycled some old luminance frames from 2022 to have more data.  Overall there's 320*60 sec of luminance and 40*60sec for each color channel, in rather mediocre conditions (moon, haze, average seeing).

 

Here's a crop on the galaxy, which is not that big (click for the full-resolution, uncropped version)

Curiously this part of the sky is relatively poor in distant background galaxies, especially compared to other parts of Pegasus.

 

 

Clear skies,

 

Dan
