AstroDMx Capture 2.18.1 Released (All Platforms)

I’m pleased to announce the release of AstroDMx Capture 2.18.1. This is a significant release that implements full support for the SVBONY SC571CC full 16-bit camera and also implements a new 16-bit transform as well as other improvements.

SVBONY SC571CC

AstroDMx Capture now has full support for the SC571CC camera. This is a true 16-bit TEC cooled camera which is proving to be an exceptional deep sky camera.

16-bit Transform and Preview Display

This release introduces a highly optimised image processing engine featuring a mathematically robust Median Absolute Deviation (MAD) and Midtone Transfer Function (MTF) transform pipeline. This update provides astrophotographers with precise automated stretching, bringing out faint deep-sky details instantly in the live previewer without manual setup.

The MAD/MTF transform can be improved by changing the display quality setting which is located in the Controls: Preview control group. Note: increasing the display quality uses significantly more memory and requires a relatively fast CPU.

Alongside these visual upgrades, the core rendering engine has undergone a major performance and architectural overhaul. This improves the rendering loop performance significantly especially on single-board hardware like the Raspberry Pi 5

FITS Improvements

Two new keywords have been added.

IMAGETYP: This field holds information about the image intent. It can be set in the primary image capture dialog or is auto-set when capturing calibration frames via the built in calibration capture functionality. The values are:

• Light
• Dark
• Flat
• DarkFlat

FILTER: This is a FITS keyword that holds the filter name. If a supported filter wheel is connected, this information is updated automatically. If not using a filter wheel, then the user can now enter the name of the filter that is currently in use. This is set in the primary capture dialog.

Warning Messages

As AstroDMx Capture continues to grow in capability, the demands placed on the host system have naturally increased. While the software remains compatible with a wide range of hardware, very low-specification systems can sometimes struggle to provide the performance needed for smooth image capture and preview display.

To help users identify potential performance limitations, AstroDMx Capture now includes optional hardware advisory notifications. The application will warn when running on systems with fewer than four CPU cores or less than 4 GiB of installed memory. These notifications are intended as guidance only and do not prevent the software from running. Users who wish to continue using older or lower-powered hardware may permanently dismiss the warnings using the provided “Don’t show again” option.

General

For more information about this release, please see the changelog. The new version (2.18.1) can be found on the main downloads page.

The post Release notes for 2.18.1 first appeared on AstroDMx Capture.

We’ve expanded hardware compatibility with the addition of three new SVBONY cameras:

• SVBONY SC715C
• SVBONY SV305C PRO
• SVBONY SV905C2

These cameras are now fully supported, bringing more options for astrophotographers.

New Features & Enhancements

16-bit Auto Stretch Transform

A new 16-bit auto stretch transform has been added, improving real-time image display for high bit depth captures. This option can be found under the “Controls: Preview” control group and is non-destructive. This means that this functionality does not affect the saved data.

Native Apple Silicon Support for QHY Cameras

QHY cameras now run natively on Apple Silicon (M1/M2/M3/M4), eliminating the need for Rosetta translation and enhancing performance.

User Interface Changes

The user interface for Mounts, Focuser Devices, Filter Wheels, and INDI Cameras has been redesigned to improve usability. These changes enhance workflow efficiency and provide a more intuitive experience.

If you’re upgrading from a previous version, please check the updated UI layout to familiarize yourself with the new design.

SDK Updates

To ensure the best camera performance and support for the latest cameras, we’ve updated multiple camera SDKs:

• SVBONY SDK
• Touptek SDK
• ZWO SDK
• Atik SDK
• OGMA SDK
• PlayerOne SDK
• OmegonPro SDK
• QHY SDK (includes firmware updates for Linux users)

Significant Internal Refactoring

This release includes major internal refactoring of the legacy codebase for advanced controls, specifically Mounts, Focusers, Filter Wheels, and non-native cameras. These changes enhance maintainability, performance, and long-term scalability.

While this refactor does not introduce visible new features, it lays the groundwork for future improvements. Additional refactoring is currently in progress and will be included in a future release.

For more information about this release, please see the changelog. The new version (2.12.1) can be found on the main downloads page.

The post Release Notes: 2.12.1 first appeared on AstroDMx Capture.

The AstroDMx Capture website has been redesigned from the ground up and most of the content has been rewritten. There’s a revised section called AstroDMx Overview which covers most of the main functionality as well as specific technical pages for Linux, Windows, macOS and ChromeOS that hopefully will help the user.

Please feel free to contact me if you have a problem using this site.

This website also has a new page called “News”. I will post updates about new versions and highlight known issues here as and when they become available or pertinent.

AstroDMx Capture is an astro imaging application (astrophotography) designed specifically to be platform independent. It’s available for 64-bit Linux, 32-bit and 64-bit Raspberry Pi (and other ARM based Linux distributions), macOS, Windows and ChromeOS.

• Touptek;
• OmegonPro;
• Bresser (Touptek Derived Cameras).

If supported by the camera hardware, each of cameras listed above have full cooling functionality implemented. That is, fan speed, dew heater, cooler power and cooler target temperature. The hardware specifically tested is as follows, however, any camera by the same manufacturer should function correctly.

• OMEGON veTEC533c;
• MTR3CMOS09000KPA.

The new release can be downloaded from the main downloads section of this website.
