Markarian's Chain, captured on April 2nd. Every astrophotography session is a learning opportunity. For this image, the main issue was to contend with the gradient (despite shooting at a Bortle 3 location since there's still quite a bit of light pollution to the east and south). I used the method described in https://astrobackyar...ents-photoshop/ with some modification, and it worked out well.

And a wider view showing M87, M88, M89, M90, M91, M58, and others. What an amazing piece of sky - and this is not even the full frame. On the full frame I counted more than 100 galaxies!
