MaxIm DL

MaxIm Intro

MaxIm DL Software

Cyanogen Imaging® MaxIm DLTM is the complete integrated solution for all of your astronomical imaging needs. Whether you are collecting and analyzing science data, or making beautiful portraits of the night sky, MaxIm DL Pro includes everything you need.

Product levels available:  MaxIm LT (SBIG camera control, webcams, and basic processing only), MaxIm DL IP (image processing only),  MaxIm DL Pro ( includes all cameras and features), and MaxIm DL Pro Suite ( all Pro features plus MaxPoint software, ).  See Compare tab below for details.

Also available:  MaxIm DL Maestro – synchronize multiple cameras operating simultaneously.

MaxIm DL PRO Suite

Product Levels



Cyanogen Imaging® MaxIm DL™ 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.


Key Features (MaxIm DL Pro level)

MaxIm DL runs under Windows 32-bit and 64-bit operating systems.  Please see System Requirements for more information.

Please see Compare tab above for the feature list for each product level.  Additional details are available here.
