Sh2-273 in high resolution
To complete the set of my Sh2-273 images in the gallery, I created this high-resolution photo by combining datasets from SPA-3 and AUS-2 telescopes. Both telescopes have the same aperture and focal length and were equipped in the past with the same CCD camera model. With 9um pixel size, frames are significantly under-sampled. Two datasets have around 70 frames per filter, enough to try dithering while processing them.
