Astrophoto image & video processor. Full cycle with new technology
Astronomy program for selecting, viewing, aligning and stacking images. Creates 16-bit AVI gray/color video files from images series, concatenates videos together into one video file. The program helps to rebuild sequences of images and restore continuous order of files after they were edited, deleted, renamed or moved. PGMania converts images from one format to another. Supports batch converting operations, also for image sequences. Image formats can be any of well known image formats 8/16/32 bpp b/w/c. The program aligns and fits the pairs of images or image series, with each other or over master, calibrates them in pairs. Program detects stars and get stars statistics. Calculates fwhm, snr and star magnitudes. Image editor with alive histogram, contrast stretching, filters, evaluates and post process. XML and txt logging of all actions and results. *) PGMania uses original algorithm for image calibration. No need for dark & bias files for calibration and fit images.
This program serves for calculation coordinates centers of maps for drawing up a uniform collage. Данная программа служит для расчета координат центров карт для составления единого коллажа.
