Depending on your camera and telescope aperture the known good values are known to vary between 2-5 seconds of exposure and 5-200 units for -sigma. The -sigma option can be used in conjuction with the exposure time to improve the detected stars SNR and limit the number of items interpreted as stars. Try to estimate field size from FITS headers Recommended options to experiment with: -sigma Nĭo not create a new FITS file with integrated WCS headers Target declination (from telescope if applicable)Īny/all options changing output file locations and names Working directory (thru AstroTortilla config file)Ĭonfiguration file location (thru AstroTortilla) Reserved options not available as custom options (showing only short variants): -D The majority of the command-line options for solve-field can be set thru the xtra configuration entry or thru the GUI entry Custom options. The plate-solver engine is used to determine the location, orientation and coverage of the imaged star field.
Set the nebulosity option to "3" instead of "2" and point the path to your Nebulosity 3 installation directory. Nebulosity 3 may work, but it has not been tested. Nebulosity module has been tested with Nebulosity 2.4 and 2.5 only. The current image name in Nebulosity is not changed. The resetpath option supports following parameters (use escaped form in configuration file): %(date)s If the resetpath is set, the given value is set as imaging directory after the image for plate-solving is taken. Nebulosity module cannot detect current imaging directory from Nebulosity and thus it has to set the imaging directory to a temporary one. Setting a filter value to -1 means current filter, any other value is passed as filter index to supporting imaging software.īinning is always set as symmetric, and it's supported by MaxImDL, Nebulosity and ASCOM camera modules. The MaxImDL and Nebulosity camera modules support using a specific filter for solved images. Minimum telescope property refresh interval The search radius and RA/dec information is not used when solving an image from "GoTo image" or "Add bookmark from image". One additional performance test is to make sure your Cygwin doesn't have Bash autocomplete enabled, it can add several seconds to the solve time if enabled. The fastest way to solve an image is to use a scale_low a bit smaller than your actual image size and searchradius of around 45 degrees (eg EQASCOM cannot sync with >45degree mismatch), to use binning instead of down-scaling, to disable plotting and to optimize the exposure-time and -sigma values for approximately 100-200 stars. If you see a systematic error of a few arc-minutes, you can try changing the epoch setting.

If set, all work will be done under the given directory. Log file name (name only or absolute path) Settings_path = C:\Users\MyUserId\AppData\Local\astrotortilla.sf.net\AstroTortilla There is no need to have any particular section present in a configuration file, and it is recommended you edit the additional saved configuration files to cover only the parts of AstroTortilla settings you want to change quickly and easily on the field. The percent -sign ( %) must be escaped with another escaped-sign in the configuration file. The configuration file structure uses the familiar INI-file structure and it is currently in 7bit ASCII only. This enable creating a quickly switchable profile library for different telescopes and for annotated plots from stacked images. leave only the solver specific section in the files. You can remove any unwanted sections from the saved configuration files, e.g. It is recommended you save the configuration files into the default directory. You can also store additional (partial) configuration files for quickly switching between various setups.
AstroTortilla stores its configuration files in the user's application local settings directory structure, under the astrotortilla.sf.net\AstroTortilla directory.
