Description

13 Hours of 55second exposures from my light polluted driveway in Arlington. This is the Cone Nebula (on the left) and the Christmas Tree cluster, and a whole lot of nebulosity that I'm loving.

As with my other images, this was taken with my D750 DSLR (unmodified), attached to an AR102, riding on an AVX mount, guided/automated by NINA.

Because this is an emission nebula, I did shoot it through the Orion SkyGlow filter, and as soon as I can arrange for a couple days of uninterrupted time on the home PC I'm going to use APP to separate Ha and OIII channels so I can play with HOO coloring. The skyglow filter really isn't enough of a narrowband filter to do HOO justice, but it does a passible job for someone at my skill level.
