Here’s my latest image that I took over the warmer summer months. Seems so long ago that I got this data, but it sat for some time waiting to get processed. I like dark nebulae a lot, but they’re pretty challenging to image from my house due to the LP. This one is a more prominent dark nebula and was barely visible in one frame. The contrast was largest with the red filter since most of the intervening dust scatters blue light and appears more reddish-brown.
As always, C&C are welcome!
The dark nebula LDN 673 is a massive molecular cloud complex about 7 light years across in the constellation Aquila and lies some 600 light years away. Mixed in with the dark cloud is a very rich star field, some of which are formed within these clouds.
