Description

Fun time out at the dark site! First time out at my dark site Bortle 4 with the Samyang lens. And first light using the new L-xtreme filter! I really like the data it collects! You have to do long exposures though. I definitely need much more Integration time on this target.
Seeing and transparency was the best it has been in months. 8/10.
The Uv-Ir data was captured from my Bortle 7 backyard. I only used this data for some star color.
