Enhanced Feature List as of 03/04/08
and Download Page

Every bug reported to us via aip4win@willbell.com since the release of version 2.1.10 that we could reproduce on our computers has been corrected in this release. Additional enhancements are as follows.

To reduce congestion we have three download sites for this update:
Site 1
Site 2
Site 3

NOTE: AIP4Win V2.2.00 requires that you uninstall your current version of AIP4Win before you begin the new install of V2.2.00.
(Start/Settings/Control Panel/Add or Remove Programs, and select the currently installed version and click on "remove".)
Before you do this install, backup your AIP4Win\Data folder (to preserve your user-customized data).
The update is provided as a compressed ZIP file which must be decompressed to retrieve the AIP4Win V2.2.00 install program.

DSLR Raw Image Loading. DSLR raw images now open directly to color. Color balance and brightness adjustments are specified in the Preferences menu, so that once you have found the optimum setting for your camera, your raw images will be opened with those settings. We recommend using your camera’s “daylight” color balance, and setting AIP4Win to open images using the camera’s color balance. Click here for more details (PDF)

• The New Color Image Tool. This tool provides a fast and effective way to adjust the brightness, contrast, and color balance of any color image (DSLR raw-format images as well as all other color images). The new Color Image Tool uses intuitive histogram-based controls (similar to the Levels control in PhotoShop) supplemented with automatic endpoint setting and additional controls for image gamma and color saturation.

Enhanced Auto-Process Deep-Sky Tool. Take advantage of stacking to multiply your image depth. You can now stack DSLR raw, JPEG, and color TIFF images. The addition of sigma-clip stacking allows you to remove cosmic rays, airplane trails, and improving the roundness and quality of star images. Click here for more details (PDF)

• The Enhanced Histogram Tool. Histograms are vital to accurate image processing. The histogram tool has been enlarged and made more flexible. You can select and control a range of pixel values in your histogram, and then float your mouse over the histogram to read out the pixel value versus percentile values. For those with an analytical bent, histogram data to can now be saved to a DataLog for plotting in Excel or other spreadsheet software. Click here for more details (PDF)

• The Enhanced Pixel Tool. The Pixel Tool now provides statistics and histograms for selected regions. You can analyze the characteristics of your images with more precision and more control than ever before. You can even set the range of pixel values and bin size to customize your histograms. Statistical information and histogram data can be saved to a DataLog for plotting in Excel or other spreadsheet software. Click here for more details (PDF)

• User Defined Image Resizing. Different strokes for different folks. If you’re stacking images or joining color channels to make color images, use the Auto-Size mode. If you’re measuring or analyzing images, turn off Auto-Size and you have full control over the size and location of the images you’re working on. Just check (or uncheck) a box in the Preferences > Customize tab to customize AIP4Win the way you like it. Click here for more details (PDF)

• The Magnitude Estimation Tool. Accurate CCD photometry is now as easy as click-on-thevariable, click-on-the-comp-star, and click-on-the-check star. Based on the time-proven methods used by the American Association of Variable Star Observers, the magnitude estimation tool is designed to be used with AAVSO charts and field photometry. Data is output to the DataLog in a simple text format or in the AAVSO’s Extended Format v. 1.1. Click here for more details (PDF)

• The Enhanced Multi-Image Photometry Tool. Since AIP4Win’s release, observers have performed photometry on millions of images using this tool. In addition to the standard formats, data can now be output to the DataLog in the AAVSO’s Extended Format v. 1.1. Click here for more details (PDF)

• The Enhanced Profile Tool. With a sweep of the mouse, you can see a “slice” of data from your images. Observe the intensity distribution of a comet; quantify the brightness of the spiral arms of a galaxy. Data from the Profile Tool can be saved to a DataLog for plotting in Excel or other spreadsheet software. Click here for more details (PDF)

• The Enhanced Magnifying Glass. For fast and detailed inspection of your image, use the magnifying glass. Enlarge areas of interest up to 1600%; see every pixel large and clear. Very useful, especially with today’s enormous DSLR images. The new Magnification Tool goes from 200% to 1600%. Click here for more details (PDF)

• Series Analysis Tool. If you have a large number of images that you want to analyze, the series analysis tool can help you. You can gather statistical information for a whole image, a defined region, or a single pixel through the whole image series. Check the stability of temperature control in dark frames; monitor the increase in sky brightness in long stacks of photometric images. Data from this tool is saved in the DataLog.

• Characterize CCD Camera Tool. Observers who are interested in science applications of CCD images need to know the gain, readout noise, and mean dark current of their CCD camera. This tool now uses an improved method that requires two bias frames, two flat frames, and one long-exposure dark frame. Click here for more details (PDF))

• Julian Day Calculator. No need to go on-line in search of the Julian Day. AIP4Win provides an improved JD calculator that includes the time zone, clock error correction, and heliocentric correction to compute JD or HJD, plus a separate tab that computes sidereal time, hour angle, and air mass for an object of your choice.
