Autofocus support for 2 cameras, 2 focusers, across 2 imaging platforms. Most users will configure one imaging software platform (MaxIm DL, TheSkyX Camera Add-on) to control the main imaging camera and autoguider. At the push of a button or via a script, you can toggle between each system configuration and autofocus your telescope hands-off. FocusMax V4 allows the user to configure their imaging system:
Imaging platform #1
Imaging platform #2
Multiple precision focusing algorithms are provided allowing further optimization of your autofocus configuration.
Focus Convergence is a dynamic focus algorithm which adapts to varying seeing conditions to provide the best possible focus to place your optical system in the “Critical Focus Zone”. If seeing is good then the focus process may require only a few images. If seeing is poor, which is typical in early evening, then FocusMax will take additional images until the predicted focus position meets user requirements.
Use AcquireStar to automatically find and acquire a suitable focus stars using PinPoint or TheSky X Image Link technologies. Define the magnitude range for each filter and FocusMaxV4 will find multiple stars, slew the telescope, center the star, autofocus then return to original position in the sky at the push of a single button or via script
Graphics and simple statistical tools are provided to:
Display autofocus progress due to seeing variation
Quickly assess the quality of Vcurve data
Analyze temperature compensation data for focusers with temperature sensors
FocusMax V4 provides an extensive COM interface to allow host applications such as CCDAutoPliot, ACP/ACP Scheduler, and other automation programs to set autofocus parameters and initiate automated autofocus runs. Custom scripts may be created by the user to accomplish specific goals which can be loaded on the System window and run. An example might be a script to set the zero of a Crayford style focuser to remove potential slippage of the drawtube that can occur due to the weight of the hardware that it is supporting.
First Light Wizard quickly characterizes your optical system to autofocus
Temperature Compensation Wizard collects data during the night for determining your temperature coefficient. The temperature coefficient once define, may allow you to extend the time between autofocus runs so that more time is available for valuable observing time.
Jog functions are available to eliminate hand controller:
Focuser Jog window can be opened to jog the focuser in/out or to move to a specific location
Telescope jog control is available to aid in centering a star for autofocusing
Other FocusMax features include:
the ability to define focus exposures for each filter.
focuser position and temperature are continuously updated in real time
ability to save Vcurve and autofocus images during the night for future review
integrated telescope monitor of position - Ra, Dec, Local Sideral Time, Hour Angle, Azimuth and Altitude
a Log window may opened display focuser temperature and position during the observing session
you may change font and font size which is useful for laptop users
ability to enable temperature compensation for focuser with temperature sensors
ability to customize the interface with different style buttons and colors.
