Picko

http://integral.physics.muni.cz/picko

Picko is an utility to convert of Christian Buil PIC images to the astronomical FITS image format. This format has been introduced by Christian Buil's PIC. To his own cameras. I've no physical access to the camera or an archive, so picko is not now activelly maintained (and I don't plan it). However, one can be freely use and also anybody can send patches to add any improvements. Is freely available under GPL2 license. Is a converter from FITS to PNG. Munipack. Picko is free software.

Rawtran

http://integral.physics.muni.cz/rawtran

Rawtran is a wrapper around dcraw. Designed to produce images in standard astronomical FITS format from raw (CR2, CRW, MRW, etc.) photos. Selected digital cameras offers possibility to save raw photos. Eg only slightly pre-processed photos intended for further image processing. Rawtran is developed as a wrapper around dcraw. By DCoffin to produce FITS. Proper conversion of data acquired by common digital cameras has two key features:. And its proper handling is important for photometry or spectroscopy in...

If anything can be forget, it will be. I spend many sleepless nights during preparation of last release of Munipack. When no convergence occurred up to morning blue hours. The new feature, which I developed, was improvement of the robust algorithms which implements join estimation of location and scale parameters of statistical distributions. Square of gradient of the function. The final result, on figures, is self-describing. When initial estimate of the gradient method falls inside of pit, on the l...

If anything can be forget, it will be. Recent progress in RAWTRAN. There is a summary of last progress in rawtran (see previous posts: Dec 2008. I specified more precissely of the definition of the FITS color format. Be inspired by PNG format ( libpng. I introduced a new keyword to the first dummy header. I added another type of conversion. The new type 4 produces multi-band FITS file including of all four Bayer colors in separated FITS image arrays. The type provides absolutely raw access to RAW...This ...

If anything can be forget, it will be. It's right time for an another development snapshot of Munipack. I have no time and no strength to stay in intense developing during our semester period. Before two months of stagnation, I issuing a rolling progress of Munipack. The issue is still experimental. The debugging is switched on by default. Don't be confused from a lot of mash prints. Many improvements in image loading, image manipulation or safe thread handling leads to more usable and stable application.

If anything can be forget, it will be. Astronomy HDR still in its infancy. I've currently experience with using global mapping methods which non-linearly compress high to low ranges. When, we defines contrast as ratio of intensity of a detail against to a local mean, the contrast is compressed together with intensity. As result of the compression, pictures has characteristically softened details. The algorithm for taking photos has been:. I taken set of exposures with different exposure times to cover fu...

If anything can be forget, it will be. I added experimental support for astrometry to Munipack. It is primary designed for astrometry on CCD. So only gnomonical projection and affine transformation (shift and rotation) are supported yet. Both limitation can be freed in future releases. The astrometry code is available in GoogleCode. I coded my own implementation of the widely-known "Astrography plate. Measurement" ( Smart and Green. Coordinates for every object. The described algorithm is relative genera...

Konve

http://integral.physics.muni.cz/konve

Konve is an utility to convert of legacy SBIG ST-x images to the astronomical FITS image format. The ST format has been introduced by SBIG. Just for fun, the word. The utility is not too useful in 21. century, so konve is not now actively maintained (and I don't plan it). However, one can be freely use and also anybody can send patches to add any improvements. Is freely available under GPL2 license. The binary along with manual page are available in current directory. It is recommended copy its under.

Exploding Galaxies and other Catastrophysics: January 2014

http://superwinds.blogspot.com/2014_01_01_archive.html

Wednesday, January 29, 2014. An introduction to quantative astrophotography on Linux: Part 1. The aims of this first experiment are to get answers to the following questions:. What kind of astrophotography can be accomplished with a basic DSLR and a static tripod in the middle of suburbia? What kind of spatial resolution, signal-to-noise, and limiting magnitude can we achieve without specialized equipment? What are the basic physical characteristics of DSLR astronomical imagery? I set the tripod and came...

If anything can be forget, it will be. I had introduced new naming schema for releases. The naming will be inspired by the crucial development feature. Naming of the current release is emphasizing development of color handling utilities (coloring, color tuning, color space conversions, etc.). Last stable release has been issued on 2010, February. I think the period is really very long. The current release does not includes color related features,. But many other important improvements. Namely,. Also I tr...
