Since this mirror started out as a tube dob I can't really call it first light.
I didn't stay out long. It's 12F outside right now. I just wanted to do a rough collimation and check my focus point. The secondary only needed a couple of little tweaks, but the primary was off by a mile. I expected it to be a little closer than it was. I touched that up and then checked focus. I had used some wooden trusses to test for the proper length so I would only have to drill the holes in the aluminum trusses just once. All my eyepieces came to focus and I had plenty of travel in both directions.
The wind started blowing so I took a quick picture and brought the scope back in the house.
