Astro Photo

These are taken by 210mm focal length optics. As far as I know, this is ever the shortest focal length as telescope and creates sharper, cleaner and higher contrast images than conventional telephoto lenses. Also please note these were taken by the Hutech performance-enhanced camera. So you can see that the halo around bright stars are very minimal even in long exposure.
