Configuring Pixinsight LE
After installing Pixinsight LE, you can launch it by clicking on the desktop shortcut or the Start menu folder. The first time you run Pixinsight LE, you will see a welcome screen with some information about the application and its features. You can close this screen by clicking on the X button at the top right corner.
The main window of Pixinsight LE consists of a menu bar, a toolbar, a status bar, and a workspace area. The menu bar contains various commands and options for working with images and processes. The toolbar provides quick access to some frequently used commands and tools. The status bar shows information about the current image and process. The workspace area is where you can open and manipulate images.
To configure Pixinsight LE according to your preferences and needs, you can go to Edit > Preferences on the menu bar. This will open a dialog box with several tabs where you can adjust various parameters such as interface appearance, file formats, memory usage, color management, keyboard shortcuts, etc. You can also access some of these parameters by right-clicking on the toolbar or the status bar.
One of the most important parameters to configure is the color management system (CMS). This is essential for ensuring accurate color reproduction and consistency across different devices and applications. To access the CMS settings, go to Edit > Preferences > Color Management on the menu bar. Here you can select the color profiles for your monitor, your camera or scanner, and your printer. You can also enable or disable color management for different image formats.
If you are not sure about which color profiles to use, you can use the default ones provided by Pixinsight LE or consult your device manuals or manufacturer websites. You can also download and install additional color profiles from various sources on the Internet.
Using Pixinsight LE
Now that you have Pixinsight LE installed and configured, you can start using it to process your astrophotography images. Pixinsight LE offers a variety of tools and processes for different tasks such as calibration, alignment, stacking, noise reduction, color correction, sharpening, and more. In this section, we will give you a brief overview of some of the most common and useful processes in Pixinsight LE.
Calibration
Calibration is the process of removing unwanted signals from your images, such as bias, dark current, flat field, and bad pixels. Calibration improves the quality and accuracy of your images and prepares them for further processing. To calibrate your images in Pixinsight LE, you need to have some calibration frames taken with the same camera settings as your light frames. These include bias frames, dark frames, and flat frames. You can also use master calibration frames that are created by combining several individual calibration frames.
To calibrate your images in Pixinsight LE, you can use the ImageCalibration process. This process allows you to select the light frames and the corresponding calibration frames, and apply the calibration automatically. You can also adjust some parameters such as scaling factors, pedestal values, rejection thresholds, etc. To access the ImageCalibration process, go to Process > Image Calibration > ImageCalibration on the menu bar.
Alignment
Alignment is the process of registering or aligning multiple images of the same object or field. Alignment ensures that all the images have the same orientation, scale, and position on the sky. Alignment is necessary for stacking or combining multiple images to increase the signal-to-noise ratio and reveal more details.
To align your images in Pixinsight LE, you can use the StarAlignment process. This process uses a star detection algorithm to find and match stars in different images and calculate the transformation parameters to align them. You can also adjust some parameters such as star detection sensitivity, distortion correction mode, output file format, etc. To access the StarAlignment process, go to Process > Image Registration > StarAlignment on the menu bar.
Stacking
Stacking is the process of combining or adding multiple aligned images of the same object or field. Stacking reduces the noise and increases the signal in your images, resulting in a higher dynamic range and more details. Stacking also allows you to apply different weighting schemes or rejection algorithms to optimize the quality of the final image.
To stack your images in Pixinsight LE, you can use the ImageIntegration process. This process allows you to select the aligned images and apply different combination methods such as average, median, sigma clipping, etc. You can also adjust some parameters such as normalization mode, pixel rejection mode, output file format, etc. To access the ImageIntegration process, go to Process > Image Integration > ImageIntegration on the menu bar.
Noise Reduction
Noise reduction is the process of removing or reducing unwanted random variations in your images, such as graininess, speckles, or artifacts. Noise reduction improves the clarity and smoothness of your images and allows you to enhance faint details. To reduce noise in Pixinsight LE, you can use different processes depending on the type and scale of the noise.
For small-scale noise, such as high-frequency noise or hot and cold pixels, you can use the ATrousWaveletTransform process. This process allows you to apply noise reduction selectively on different wavelet layers, which represent different spatial frequencies in your images. You can also adjust some parameters such as scaling function, scaling sequence, noise threshold, etc. To access the ATrousWaveletTransform process, go to Process > Wavelets > ATrousWaveletTransform on the menu bar.
For large-scale noise, such as low-frequency noise or gradients, you can use the SGBNR process. This process allows you to apply noise reduction based on a mask that defines the background areas of your images. You can also adjust some parameters such as mask size, mask smoothness, noise threshold, etc. To access the SGBNR process, go to Process > Noise Reduction > SGBNR on the menu bar.
For images that need more advanced color correction, such as removing color casts, enhancing color contrast, or applying custom color mappings, you can use the PixelMath process. This process allows you to apply mathematical expressions to manipulate the pixel values of your images. You can also use variables, functions, operators, and conditional statements to create complex formulas. To access the PixelMath process, go to Process > PixelMath on the menu bar.
Sharpening
Sharpening is the process of enhancing the contrast and detail of your images, to make them more crisp and clear. Sharpening can also help to reveal fine structures and features in your images that may be blurred by atmospheric turbulence or optical aberrations. To sharpen your images in Pixinsight LE, you can use different processes depending on the scale and type of detail you want to enhance.
For small-scale detail, such as stars or planetary features, you can use the ATrousWaveletTransform process. This process allows you to apply sharpening selectively on different wavelet layers, which represent different spatial frequencies in your images. You can also adjust some parameters such as scaling function, scaling sequence, noise threshold, etc. To access the ATrousWaveletTransform process, go to Process > Wavelets > ATrousWaveletTransform on the menu bar.
For large-scale detail, such as nebulae or galaxies, you can use the MultiscaleLinearTransform process. This process allows you to apply sharpening based on a multiscale analysis of your images, using linear filters such as Gaussian or Laplacian. You can also adjust some parameters such as filter type, filter size, filter shape, etc. To access the MultiscaleLinearTransform process, go to Process > Multiscale Processing > MultiscaleLinearTransform on the menu bar.
For more advanced sharpening techniques, such as deconvolution or unsharp masking, you can use the PixelMath process. This process allows you to apply mathematical expressions to manipulate the pixel values of your images. You can also use variables, functions, operators, and conditional statements to create complex formulas. To access the PixelMath process, go to Process > PixelMath on the menu bar.
