Download DeepSkyStacker 4.2.6

Note: the installers will uninstall any previous version of DeepSkyStacker.

PLEASE NOTE: If you get a message saying: "This programme can't start because api-ms-win-crt-runtime-l1-1-0.dll is missing" the solution is to install for your specific version of Windows.

This problem should only affect users of Vista / Win7 / Win 8.x who are behind on WindowsUpdates, or are running an offline system and opting out of WindowsUpdates.

The list of the DSLRs supported by the latest version is available on the libraw web site.

Alternatively you can convert your RAW files to DNG using the free Adobe DNG Converter available here before feeding them to DSS.

Changes in previous version  3.3.2

Integration of DCRAW release 8.98 rev 1.431

Bug Fixes:
The dark factor used to optionally scale dark frames was incorrectly used. Fixed
Ampglow was sometimes incorrectly considered as a group of hot pixels. Fixed.

Previous Release Notes

Installation: just unzip in any folder and run Setup.exe.
In case of installation problem (dll is missing...) check that you are using the latest Windows Installer which you can download
here. This could be the case especially if your are running Windows XP without the SP2.

Supported platforms:
Windows XP SP2, Windows 2000, Windows 2003 Server, Windows Vista, Windows 7, Windows 10
(it may work with Windows 98 and Windows NT 4 but I never tested these platforms and I can't guarantee it).
GDI+ must be installed. If you are not using Windows XP, Windows 2003 Server or Windows Vista,
click here to download GDI+ for your platform
(GDI+ is already installed with Windows XP, Vista and 2003 Server)

Minimum resolution: 1024x768

Memory requirement: depends of the pictures sizes.
256 Mb for small pictures (less than 1000x1000 pixels)
512 Mb for pictures created with a DSLRs like the Canon EOS 350D
Of course, the more the better (It avoids using the swap and speeds up the processes)

Processor: from an 800 MHz PIII.
Again, if you want to speed up the processes the faster, the better.
