Shot this earlier this month as I was waiting for another object to get high enough to shoot. Scaled darks, so not the best.

Looks nice. I can see a hint of the shock waves toward the core. Martin

Hi Robert,
I was curious why you used such a short sub frame? I am always struggling with this as to what is right. The Starizona site has a calculator to determing "ideal" exposure and I have used that sometimes. But, 2.5 minutes seems pretty short.
