Hi Folks;

I had really good seeing early on last night and managed to capture M56 (faint small globular cluster) with good definition:

and then M15 with it's super bright core of stars:

Seeing was more turbulent for M15 and I was guiding off a Mag 8.x star too.

This was the same set up used for my Veil image excpet 7 minutes Luma, 8 minutes red, 6 minutes green and 6 minutes blue exposures. I'm hoping to capture M29 or maybe M11, depending on turbulence, as the weather turns cloudy / unstable starting tomorrow afternoon and stays that way for the rest of the week, or at least I hope it does. We could use some rain and a break from the 30 to 37°C heat wave.

TTYL..
