Product Description

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.

  • Complete observatory integration. Controls all of your astronomical equipment.
  • Integrates your camera, autoguider, filter wheels, focusers, camera rotator, telescope mount, observatory webcam, remote switches, weather station, and dome.
  • Fully ASCOM compliant.
  • Built-in mini-planetarium helps you maintain “situational awareness”.
  • Designed for efficiency. Create your own presets for finding, centering, focusing, and imaging sequences.
  • Multithreaded hardware interfaces for smooth and responsive operation.
  • Automated shutdown with user-definable triggers (including weather) and sequencing.
  • PinPoint V6 with online all-sky solving – easily recover if your telescope gets lost.
  • Automatic pier flipping with guide star reaquisition.
  • Multistar and differential autoguiding.
  • Monitor and control your observatory with dome webcam, remote switches, and weather monitoring.
  • Stack hundreds of images of different targets in one operation – with automatic alignment and bad data rejection.
  • Blend in narrowband data to create fully realistic images or false color representations of your data.
  • Includes a complete image processing toolkit, including a large variety of filters, deblooming, curves, deconvolution, color tools, and much more.
  • Analyze multispectral photometry data for huge numbers of images including multiple targets; export light curves and AAVSO reports.
  • Instant Raw image color preview – see Raw images in full color without Bayer conversion.


  • Complete integration of all your observatory hardware in a single package.
  • Supports your equipment – compatible with more equipment than any competing package. Supports ASCOM equipment plus a huge variety of cameras and filter wheels.
  • Multi-threaded equipment control for smoother operation.
