Grab n' go imaging with JrPro

I decided to try my grab n'go with the Jr Pro this weekend (8/7). The ST-80 is F5, but I used a Barlow lens for the images of the Dumbbell and the Ring Nebula. Planetary nebulae have a small angular diameter and they are vanishingly small in the ST-80 FOV. I cropped the images and made some adjustments in Photoshop (it was a warm night and the Jr Pro is uncooled, so there was significant noise.
