The focus throw is the amount of rotation needed to go from close focus to infinity: a large focus throw makes it easier to make finer focus adjustments. High-end modern lenses are also good at the manual focus game, but kit and budget lenses may be more difficult to focus and less precise Dual focusers are also used in astrophotography because the perfect focus is essential for a good image. Electronic Focuser. This is more like an upgrade to your existing focuser. It features a small device that is mounted on the focuser, or you need to replace one adjustment wheel with it. It is even better than the dual speed focuser because.
Auto focus software can significantly improve image focus; especially when images are captured over several hours during an imaging session. One of the biggest challenges of Astrophotography is making sure images are in focus. Manual Focus Method. Most astrophotographers do their initial focus using a Bahtinov mask to perform the initial focus . For this, we will be using a bright star as reference and achieve perfect focus in less than a minute. We also have a video walkthrough to further help you with focusing your lens In prime-focus astrophotography, the telescope both gathers light and magni-fies the image. This means it has to track the stars perfectly. That's why experi-enced imagers advise spending mor Finding razor-sharp focus when shooting astrophotography can be hard - stars appear as point light sources, and there are no detailed surfaces to aid the eye in achieving focus A Bahtinov mask can help you achieve a sharp focus for your astrophotography images. This process is an essential step of any deep-sky astrophotography session. With so much time and effort put into your polar alignment and autoguiding accuracy, it would be a shame to spoil a photo due to poor focus

Astrophotography is closer to science than art, and there is no such thing as getting it right in camera. This means you cannot simply point the camera at the sky and snap away. Lock the focus, so that the camera will not hunt for it between images. This will also help to keep the focus consistent through the shooting sequence An astrophotography camera is any camera that can be used to take pictures of the night sky. While some people use standard DSLR cameras for astrophotography, dedicated deep-sky astrophotography cameras require a telescope and software to run properly Prime focus astrophotography requires an SLR because to do it, you must remove your SLR's lens and attaching the camera directly to the telescope, effectively using your telescope as the lens. All that's required to do this is a ring adapter designed to fit your camera's mount (Canon, Nikon, etc.) and a T-Adapter which includes an eyepiece. Here I review one of Nikon's new mirrorless models, the Z6, tested solely with astrophotography in mind.
