1. How to Focus for Star Photography
2 aug 2023 · Simply put your camera on a tripod, enter live view, magnify the image as much as possible, and manually focus until everything looks sharp.
If you like taking landscape photos at night, you’ll surely be familiar with one of the main challenges: successfully focusing on the stars. Often, you can’t use autofocus, since there isn’t enough light for your camera’s focusing system to lock onto anything. Unfortunately, even manual focus doesn’t always work, which means you may need to use some out-of-the-box techniques to make it work. This article goes through some of the most useful tools that you have at your disposal.

Description: Auto focus is highly useful for keeping you in focus through the night; however, auto focus can often be difficult to understand what's going on "under the covers". This should help to demystify those issues. The purpose of the Auto Focus implementation in Sequence Generator Pro is to maintain focus through an imaging session. It is not designed to handle large focus swings. Because of this you will need to start out fairly well focused before you begin an imaging run with Auto Focus enabled.

In order to focus an image, Ekos needs to establish a numerical method for gauging how good your focus is. It's easy when you look at an image and can see it as unfocused, as the human eye is very good at detecting that, but how can Ekos possibly know that?
7. Continuous Real Time Autofocus - Innovations Foresight
Unlike traditional auto-focus software looking at the size of the star for focusing using a V curve approach, SharpLock uses the shape of the star instead.
Focusing a telescope is a fundamental task for astro-photographic imaging. Maintaining best focus is crucial but over time load transfers due to the mount motion as well as changing temperature often cause a significant change in focus, see our eduction “how much focus error is too much?” page for further information on this matter. A less known and subtle focus problem can be traced from temperature gradients inside mirrors, as well as differential thermal inertia between secondary and primary mirrors. These types of issues are not easy to solve leading eventually to recurrent refocus interruptions. Imaging software packages typically allow for periodic refocusing. The classical procedure calls for slewing the scope toward a bright enough reference star, then running an autofocus (AF) utility, such as a V curve focusing algorithm, and finally reacquiring the target. This is, at best, a time consuming procedure during which you are no longer imaging your target. It can also result in additional problems if the mount is unsuccessful at accurately reacquiring the target after the focus routine. As a general rule, every time you move away from your target, you not only lose precious imaging time but you also open the door for problems. It is quite common to find that the first frames after the target reacquisition have a poor FWHM due to the mechanical settling time linked to slewing. Our patent pending SharpLock technology provides better and unique way to deal with focus chan...
