Seven summer nights of shooting. A mosaic of five RGB regions and two Ha. Mixed up the mosaic corners again, so the lower right corner has low integration and poor SNR.

Cool. In the fall, I'll also be shooting with my Askar FRA500.

Perfect scale for a 500mm lens. I had to make a mosaic to fit it all in (560mm).

I'll be shooting with a reducer, which will give me 375mm, perfect for my 294 camera. I already have work done at the same focal length, but with a smaller tube. I'm expecting more from this tube)
