The focuser is moved per the Auto Focus Step Size, exposures are taken per the Auto-Focus exposure time, and contrast is measured via different techniques. The curve obtained is close to a Gaussian Curve, where the maximum of the curve is the point of highest contrast and therefore best focus. An example would be as per the below.
The Default Auto Focus Exposure Time won't be used if a filter wheel is connected, and Auto Focus Exposure Times have been set up in the Filter wheel section of the Options -> Equipment view. Instead, the per-filter exposure times will be used depending on the filter set at the time.
Proper focusing is a critical part of astro-imaging. Poor focus will yield softer images and lower SNR. As such it is common for imagers to focus with precision tools such as a Bahtinov mask prior to imaging.
Be out of focus Negative when starting autofocus and then start the SC autofocus routine with the Positive button. I try to get close to focus then I hit the Negative button so it takes me back at least 200 steps. Even when I back it up 500 steps things work perfectly.
An automatic solar tracker helps by allowing the solar panel to automatically shift with sunlight. An automatic solar tracker senses the sun’s position and moves a ccordingly. This means the s olar panel moves from east to west with respect to sun. There are two major types of residential solar panel tracker: single axis and dual axis.
It is possible to set an auto-focus filter, as described in the Equipment Options Section.
