Noctilove is a website devoted to low light photography and astrophotography with a barn door tracker. All of the images on this website were taken without a telescope. Just a regular DSLR and lens. You'll find images of comets, meteors, galaxies and nebulae, as well as night landscapes, Aurora, noctilucent clouds, and lightning. Almost all images on the noctilove website were taken from a light polluted area of England at sea level. Far from perfect conditions! To build up the detail and to reduce noise, images have been 'stacked' with Deep Sky Stacker and processed with Photoshop to make them as pretty as possible.
