Temperature Compensation

Temperature Compensation Wizard

The Temperature Compensation Wizard is designed to collect position and temperature data over the course of one night. The output is a Log with temperature and positions that can be analyzed using a (spreadsheet such as Excel) to determine the temperature coefficient that is entered into the focuser driver. The Temperature Log will be opened which will log the position and temperature from each autofocus run throughout the night.

Set the number attempts to recover the star and the delay between attempts. This feature is to allow time for interruptions such as clouds

Set the interval to trigger an autofocus run based on a time interval. It is a good idea to use AcquireStar to automatically select a stars from a star catalog in a magnitude range and slew the telescope:

set the desired star magnitude range

enable goto Zenith

disable Return slew

disable blind slew

Center with telescope option will require tracking a single star throughout the night. This will require that you calibrate your telescope movements - see Preferences / Telescope.

Park telescope option will park the telescope at the end of the data collection period.

Set the number of hours to run which will set the date time to stop the operation. This feature is used for unattended data acquisition.

Verify the autofocus settings before proceeding for Base exposure, min/max exposure time and Target flux

FocusMax will find the brightest star in the field and display the adjusted exposure time and the star flux

The Temperature Log will open and you see the temperature and position data from each autofocus run based on the time interval.
