Another try at M13..There was only a small break in the clouds so I took what I could get! Would've liked a few more subs. (my focusing is getting better but I would still like to make/acquire a focusing mask one of these days)
A group of Wheaton Academy students put together a detailed diorama of the allied landings in France on D-Day.
Cantigny Park in Wheaton commemorated the 70th anniversary of the D-Day landings with vehicles, reenactors and a series of engaging activities so that young people could learn the history in engaging ways. As a special treat, there were veterans of the beach landings who were there to share their experiences and answer questions.

I have removed sky background because it was too much noisy, so the rendering is somewhat space ...

Another version of M13, after having my way with it using PixInsight. I used DBE to try to fix some gradients and vingetting in the image, though I still ended up cropping the image a bit so that the background in the corners don't look too ugly when stretched. Also fiddled with the color saturation a bit, too. Same raw data as the last image.
