Description

This is kind of an unplanned experiment to see what's possible to acquire during the Santa Ana wind season in CA. During these 2 nights, the wind was between 10 and 15 mph. With the high dust content in the air, seeing was between 3" and 4" FWHM, compared to my normal 1" to 2".

I was only able to acquire 45 minutes of L during this very unsteady period and a bit more RGB. Unusual for me, but nevertheless challenging and fun to process.

"NGC 7814 is a spiral galaxy about 40 million light-years away in the constellation Pegasus. The galaxy is seen edge-on from Earth. It is sometimes referred to as "the little sombrero", a miniature version of Messier 104. The star field behind NGC 7814 is known for its density of faint, remote galaxies."
