AIP4Win v2.3.0 includes the following new features:

Improved processing for DSLR-camera images.
- Many more cameras supported in 12-bit raw images. Click here for a list of cameras that have raw file support. NOTE: YOU WILL NOT SEE YOUR CAMERA LISTED IN THE Cameras.dat file window. The Cameras.dat file has nothing to do with raw file support. The raw file support comes from one of the supporting DLLs that is automatically installed on your system. The Cameras.dat file is used by the CCD Calculator and the SNR Calculator, as well as by the file reader to determine the pixel dimensions, which are assumed to be square if the camera is not listed in the file.
- Automatic de-Bayerization when stacking images.
Improved processing for Bayer-array camera images.
- Full support of 16-bit raw Bayer-array images in FITS format.
- Automatic de-Bayerization when stacking images.
- Wide range of de-Bayerization options.
DSLR and Bayer-array options include:
- Automatic, camera, scale-factor, grayscale, or raw output formats.
- Binlinear, VNG, AHD, and PPG de-Bayerization algorithms.
- Single-point customization for settings in Preferences menu.
The Magnitude Measurement Tool for stellar photometry.
- Direct generation of AAVSO extended format reports.
- Direct generation of CBA-style reports of CVs.
- Guide-star tracking for scopes without autoguiding.
Numerous changes and improvements too many processes.
All reproducible software bugs reported by users are corrected.
