Product Description

Cyanogen Imaging® MaxIm DLTM includes an extensive suite of image acquisition, processing, and analysis tools. Starting with complete observatory integration, MaxIm DL takes you from gathering raw data through to the final high-quality result with the minimum of effort.

A typical imaging sequence will include hours of autoguided images with dither, automatic filter changes, and pier flipping – all the while slewing your dome and monitoring the weather.  Every image is tagged with extensive data in its FITS header. When your weather sensor reports unsafe conditions MaxIm DL will automatically shut down your equipment, park the telescope, and safe the dome.

Once your images are collected, MaxIm DL can automatically assemble your calibration images into groups, select the correct groups for each individual image, calibrate, and stack your images.  You can process hundreds of images from different targets with just a few mouse clicks.

MaxIm DL also includes advanced photometry and astrometry capabilities.  Photometric measurements are made using best practice median-mean and partial-pixel algorithms vetted by professional astronomers.  Astrometric measurements are performed using PinPoint LE, widely recognized as the most powerful and accurate package available today.
