The site had the following in the homepage, "Maximal Shutter Speed for Night Sky Photography without Tracking." I noticed that the web site stated " When taking night sky photography, we need to grab as much light as possible by increasing the ISO, using a larger aperture andor using a longer shutter speed." They also stated " However, larger ISO means more noise and there is a limit of aperture size. If the shutter speed is too long, star trails. The star trails can be avoided by attaching the camera on a equatorial mount."
