We had four relatively clear nights in a row. Some didn’t start great but all four produced usable imaging time even if the nights aren’t much more than 4 hours of astronomical darkness this time of year.
A couple shots with the Canon 6D DSLR and a Rokinon 135mm wide open at f/2.

This trip to Cherry Springs State Park promised an amazing clear stretch but was marred by dense smoke obscuring much of the sky from the wildfires raging in CA and other parts of the US.
We had some great weather for the annual star party at Pickett State Park, TN last new moon. This star party is still young and looking to grow. The park rangers are doing a great job, it’s a great venue for presentations and a great field for observing / photography. I’m not sure why it still remains a hidden gem of sorts.
Overall sky quality, other than some early clouds, was excellent. With SQM measurements around 21.77 mag/arcsec^2 this was the darkest I’ve seen Pickett. I would note too that of the other dark sky sites I routinely visit, this quality of night is nothing to complain about.
We had a great clear spell 7/23 through 7/27 with only moderate lunar interference in the early hours of the morning. This is 14 hours of exposure divided equally across Hydrogen-alpha, Oxygen [III], and Sulfur[II] emission lines. Scope was an AP130GTX with Apogee U16 CCD on an AP1200GTO mount. Located outside Clinton, TN. The following are crops from the main image.
Finally, here is the nearly full frame image encompassing the whole area.
With weather looking wet and wild for the 2019 Cherry Springs Star Party and things looking slightly less soggy at Calhoun we decided to cancel on Cherry Springs and gamble on Calhoun. Good thing we were setup on the top of a ridge so we never had to deal with muddy conditions considering all the rain we didn’t know was coming.
Unfortunately we were mostly clouded out for the star party. From the sounds of it some of the other big star parties going on concurrently were also clouded out. It just wasn’t a good weather weekend for a large portion of the eastern US. Regardless of the clouds, the rangers at Pickett put together some good food and speakers for the event to keep it entertaining. I stayed for only one night and snapped a few pics of the hazy skies with the Milky Way trying to peak through.
