Changes in version 3.3.0

Integration of DCRAW release 8.95 rev 1.425

Bug Fixes:
Description html file was not created when using Batch Stacking. Fixed.
Nikon Coolpix 5000 NEF files were incorrectly decoded using an RGB Bayer pattern instead of a CYMG one (other DSLRs using CYMG Bayer pattern might have been in the same case). Fixed.
Background calibration mode was not written in the html description file. Fixed.

DSS Live: Bit depth was incorrectly shown as 16 bits in the file list regardless of the true bit depth (It was not modifying the process though). Fixed.
DSS Live: Link to copy current image to clipboard was not available in the Stacked Image tab. Fixed.

Previous Release Notes


Installation: just unzip DeepSkyStacker.zip 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
(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.
