  1. I recently released DeepSkyStacker 4.2.4 Beta 4 as a release candidate. The Installers can be downloaded from here: https://github.com/deepskystacker/DSS/releases/tag/4.2.4-Beta4 The changes from 4.2.3 are: 1. Fix to display Exposure, f-Stop, and ISO setting from EXIF tags in TIFF files. 2. Update libtiff to 4.1.0 3. Automatic detection of CFA matrix based upon FITS keywords such as BAYERPAT, COLORTYP, and MOSAIC (for Meade DSI colour cameras). The FITS File tab of the Raw/FITS DDP Settings dialogue has changed. If you de-select the tick box for: "Monochrome 16 bit FITS Files are RAW files created by a DSLR or a color CCD camera", then automatic detection will be used. You can override this by selecting this option and manually selecting the CFA pattern to be used. All the other settings on that tab are now always available for modification. 4. The exposure time is now correctly displayed for FITS files with the exposure time in microseconds (keyword EXPOINUS). 5. Display a warning message saying that DeepSkyStacker won't de-Bayer 8-bit FITS images. 6. Change code to read TIFF files in strips instead of by scanline. This can reduce the time to read the image by as much as a factor of 3. 7. Refactor the code to decode the TIFF file we just read and also use OpenMP. Time to decode the image reduced by about 4-5 times. 8. Refactor the code that writes TIFF files and use OpenMP to speed it up. Also write the output file in strips rather than scanlines. Substantial performance increase. 9. Refactor the code that reads FITS files to make it easier to understand and also use OpenMP. Only a marginal performance benefit. 10. Major bug fix - calibration frames were either not applied or incorrectly applied when using Super-Pixel mode. 11. Change DeepSkyStackerLive so that the choice of using the Dark Theme is controlled by the user settings. 12. Display the FITS FILTER name in the picture list control, for information only at present. 13. Change the text used in the language selection ComboBox to always use Latin characters. This is a work around a problem with DLGINIT processing and Unicode characters. Clear skies David
  2. DeepSkyStacker 4.2.4 Beta 3 is now available. https://github.com/deepskystacker/DSS/releases/tag/4.2.4-Beta-3 Welcome to DeepSkyStacker 4.2.4 Beta 3 The main changes in this release are: Fix to display Exposure, f-Stop, and ISO setting from EXIF tags in TIFF files.

  3. Yes they do appear once you've loaded your images ...
  4. I just released DeepSkyStacker 4.2.3 https://github.com/deepskystacker/DSS/releases/tag/4.2.3-Release ************** IF YOU INSTALLED 4.2.3 BETA 1 ************** When you next use DeepSkyStacker, please restore all settings to the default using: Settings/Load/Restore Defaults before you run your stack. ******************************************************* The main changes in this release are: 1. The 32 bit version will now run on Windows XP SP3. It is likely that the next release of DeepSkyStacker will not do so. 2. The stacking settings dialog width has been increased to reduce or eliminate the need to scroll the tabs. 3. Add .rw2 to list of RAW file extensions. 4. Change the colour scheme for DeepSkyStacker Live to make it more "night vision" friendly. 5. Recognise and use GAIN values in FITS file from CMOS/CCD cameras in a manner similar to how ISO is handled for matching darks, lights etc.. Please note this is not the same as EGAIN (e-/ADU). It refers to the camera's scaling of EGAIN. 6. Update help files. My thanks to Estela Nuñez, Giovanni Benintende, Günter Heberger, José Mozart Fusco, Luc Coiffier, Михаил Тимофеев (Mickle Timofeyev), and Premysl Lukavský for their immense help with all the translation work needed for this release. Dutch help is deferred until the next release. 7. Issue #83: Provide the option to perform NO White Balance processing at all (requested by Ivo Jager for StarTools). 8. Fix for issue #42 - the stacking method "Average" wasn't always reported in the recap html file. 9. Common control library 6 now used so some cosmetic changes such as filled progress bars. 10. Make the progress dialogs non-modal so that DeepSkyStacker can be minimised while processing. 11. Update the DeepSkyStacker taskbar icon with a progress bar that matches the main progress bar. 12. Saving of final TIFF file is now faster, and a number of other performance enhancements have been made. 13. Ctrl-A will select all images in the file list (not the same as "Check All"). 14. Del key will delete an image from the file list so you don't need right click and select "Remove from list" 15. Bug fix - if you change the type of an image from the file list "Properties" dialogue, the icon was changed, but the text wasn't. 16. Bug fix - Settings were handled incorrectly in 4.2.3 Beta 1 Clear skies David
  5. Yes, it will have expired - I'm still waiting for some translation work to come back which is taking longer than I'd hoped (translator having work overload problems). I hope that I'll be able to do another beta with that translation included this month ... No promises though. David
  6. https://github.com/deepskystacker/DSS/releases/tag/4.2.3-Beta2 This beta release contains a bug fix for the incorrect handling of the settings in 4.2.3 Beta 1 which could cause problems with incorrect output or crashes and other odd behaviour. If you did install Beta 1 when you run your first stack using this release please use "Settings/Load/Restore Defaults" as the first thing you do. You should only need to do this once. This release also contains updates to the help for Brazilian Portuguese. Please could I ask any Brazilian Portuguese speakers to review the updated help and let us know of any issues. The work for translation of the help to Dutch is as yet incomplete, so the Dutch help files are still in English. Clear skies David C. Partridge
  7. I'm considering whether I should succumb to aperture fever and try to find a 14" or 16" RCX400. I'm not too concerned if the electronics have failed so long as they haven't been removed or messed with. Does anyone here have one of these in need of a new home? David
  8. The first line of my post had the URL: https://github.com/deepskystacker/DSS/releases David
  9. https://github.com/deepskystacker/DSS/releases Please note that the translation of the help is not yet done. So the help will be either as it was previously or a mixture of (e.g.) French and English The main changes in this release are: The 32 bit version will now run on Windows XP SP3. It is likely that the next release of DeepSkyStacker will not do so. The stacking settings dialog width has been increased to reduce or eliminate the need to scroll the tabs.

  10. https://github.com/deepskystacker/DSS/releases/tag/4.2.2-Release Welcome to DeepSkyStacker 4.2.2 This release is all about performance, though other areas have been enhanced as well. The main changes since 4.2.1 are: 1. Changes to star registration code to detect larger stars than before. Star radius of up to 50 pixels is now valid (it was 20 pixels). This was needed to accomodate higher resolution sensors. 2. Allow larger star sizes to the specified in the Star Mask creation dialogue. Star diameter of up to 100 pixels is now allowed. This was needed to accomodate higher resolution sensors. 3. OpenMP speedup of Star Mask image reading code. 4. Huge speedup of final image display by using much larger rectangles and OpenMP speedup of the bitmap extraction code. 5. Speed up star registration by updating progress indicator once every 25 iterations instead of each iteration. 6. Computing Final Picture using Kappa-Sigma Clip processing is now about 50 times faster! 7. Computing Final Picture using Auto Adaptive Weighted Average is now about 43 times faster! 8. Auto-Adaptive Weighted Average now re-written completely. It should no longer produce whited out images or other strange results. Thanks to Michael A. Covington and Simon C. Smith for their immense help in locating references and getting this working. Thanks are also due to Dr. Peter B. Stetson who very kindly provided a web link to his original lecture notes, emailed a PDF copy of his original paper, and provided helpful guidance. 9. Update LibRaw to 0.19.3. 10. Reverted Entropy calculation code in CEntropyInfo::InitSquareEntropies() to NOT compute in parallel - some called code wasn't thread safe. 11. Entropy Weighted Average complete stack of 50 lights is now about 20 times faster on my laptop, down from 4hrs 22min to 12min 55 sec. 12. Bug fix - changing "Set the black point to 0" or "Use Camera White Balance" after an image was loaded didn't change the rendering. 13. When loading raw files, check that the camera is listed in the LibRaw supported camera list. Issue a warning if not. 14. User request to change the file open dialog to default to *all* supported image types including raw files. 15. Three times performance improvement in star registration. 16. As requested by Ray Butler, use relative paths in saved file lists while continuing to accept older file lists using absolute paths. 17. Miscellaneous other performance tweaks. 18. Display lens aperture information in the image lists for DeepSkyStacker and DeepSkyStackerLive. 19. Don't check for LibRaw camera support if processing DNG file.
  11. https://github.com/deepskystacker/DSS/releases/tag/4.2.2-Beta3 Welcome to DeepSkyStacker 4.2.2 Beta 3 This is the final beta release for 4.2.2 with even more improvements (see below).

  13. Median Kappa-Sigma should also be somewhere around 40-50 times faster than 4.1.1 but we did that change in 4.2.0(RIP).
