Description

I've decided to shoot at the small pixel ratio/long focal length of my 8SE/Pentax K3 II regardless of the fact that the seeing at my house isn't great, being at the foot of an island mountain range, the San Francisco Peaks.

I am getting OK results and learning things, but feel like better seeing might reveal more details at .55"/px .

Learning all the time!
