Welcome to DeepSkyStacker 4.1.0
This version of DeepskyStacker is supported on Windows 7, Windows 8, Windows 8.1 and Windows 10 and completely supercedes DeepSkyStacker 3.3.2, 3.3.4 and 3.3.6.
We now provide DeepSkyStacker and the other programs as both 32-bit (x86) and 64-bit (x64) builds based upon the latest version of dcraw. There are separate installers for the 32-bit and 64-bit versions.
Installing the 32-bit build will remove earlier versions of DeepSkyStacker (3.3.2 and upward). If you are running an earlier version than 3.3.2, please remove it manually.
You can install both the 32-bit and the 64-bit versions on 64-bit versions of Windows without problems.
PLEASE NOTE: If anyone who installs this gets: "This program can't start because api-ms-win-crt-runtime-l1-1-0.dll is missing" when they try to open the programs, the solution is to install:
https://support.microsoft.com/en-us/help/2999226/update-for-universal-c-runtime-in-windows
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.
Enjoy,
Luc Coiffier, Tony Cook, David C. Partridge
We've fixed a number of problems since 4.1.0 beta 1:
-
Fixed a problem when using drizzle and Intersection mode which resulted in an output image that was 4x or 9x too large with the image in the upper left corner.
-
Worked around a problem with incorrect display of the left panel on high resolution monitors. (Set the DPI Aware flag in the application manifest to No).
-
Changed our build of libtiff so that we use Unix style rather than Win32 style I/O as the Win32 code is wrong in x64 mode (known problem with libtiff).
-
A number of other size_t/DWORD/long issues in the code were fixed for the 64 bit build (to ensure computed values were indeed 64 bit sized).
-
Small change to improve the responsiveness of the post-processing screen (faster display of the final image).
