  1. Just a short post to advise everyone of a problem. I fixed a problem in DeepSkyStacker 4.2.5 where DSS was failing to read files whose path or file name contained accented characters. Unfortunately <BLUSH> I failed to fix the code for writing TIFF files, so DSS gets all the way to the end of the process and then fails to write the output file. This will be fixed in the next version, but in the meantime please avoid the use of filenames or paths containing accented characters. David
  2. I'm referring here to the cable that the StarAdventurer manual calls the C1 cable for the EOS 60Da and similar. I thought I might use an existing 2.5mm stereo cable I had which is wired: Tip <----> Tip Ring <----> Ring Barrel <----> Barrel but no such luck. I'm guessing that the C1 cable is wired with: Tip+Ring <----> Tip+Ring Barrel <----> Barrel That's to say with tip and ring connected together and then connecting to the plug at the other end. However I'd like confirmation, so if anyone who has one of these cables and an ohm-meter to hand can "buzz" it out, I'd be grateful. Thanks, David
  3. I've just released DeepSkyStacker 4.2.5. You can get it from here: https://github.com/deepskystacker/DSS/releases/tag/4.2.5 Please note that version 5.1.0 of DeepSkyStacker (when it is finally released) will not run on 32 bit systems or Windows XP. Here's the details of the the changes in this release and in 4.2.4: Here are the main changes that were made for DeepSkyStacker 4.2.5 Remove use of predictive compression for TIFF files. Use of this revealed a long standing bug in Photoshop which was able to read the files created by DSS, but then wrote corrupt TIFF files. Correct a problem where DSS failed to read files whose path contained accented characters. Fix for a problem where DSS incorrectly reported master calibration frames from earlier releases as being incompatible when a user specified CFA pattern was used for FITS files. Fix a bug introduced in 4.2.3 which causes the code to crash when moving the sliders on the processing page. Apply a development fix to the LibRaw code which was looping forever attempting to open corrupt CR3 files. Here are the changes that were made for DeepSkyStacker 4.2.4. LibRaw updated to 0.20 providing support for over 1300 cameras including Canon Eos R (.CR3 files). CR3 file extension added to list of raw file types. ***** WARNING ***** WARNING ***** WARNING ***** WARNING ***** LibRaw 0.20 has introduced a change that primarily affects users of "older" Canon DSLR cameras and FujiFilm X-Trans series cameras (older includes the EOS 60D and 60Da)! The change is to increase the size of the frame area of the image that surrounds the "user area" so that top and left margins are an even number of pixels. The resultant image that DSS extracts from the RAW file will be reduced in width, height or both by one pixel. As result the Bayer Pattern (CFA) used for de-Bayering the image also has to change. Unfortunately the LibRaw developers won't say exactly which cameras this change applies to save to say that it is not a large number. Other have reported that at least the following cameras are definitely impacted by this change: EOS 1D Mark IV EOS 5D Mark II EOS 7D EOS 60D EOS 550D EOS 600D EOS 1200D If your camera is one of those affected, you will not be able to use any existing master frames produced with DeepSkyStacker 4.2.4 Beta 4 or earlier releases as they will not be compatible. You will need to delete and re-create your master frames from the original darks, flats etc.. I am sorry that this has happened, but it is outwith my control, and the LibRaw developers were not prepared to revert the change (they wouldn't even explain why they made the change). If there were another library I could use to decode raw images I would migrate to that but after researching it over the last several days I have come up with no viable alternative. ***** WARNING ***** WARNING ***** WARNING ***** WARNING ***** Fix to display Exposure, f-Stop, and ISO setting from EXIF tags in TIFF files. Update libtiff to 4.1.0 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. The exposure time is now correctly displayed for FITS files with the exposure time in microseconds (keyword EXPOINUS). Display a warning message saying that DeepSkyStacker won't de-Bayer 8-bit FITS images. 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. 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. Refactor the code that writes TIFF files and use OpenMP to speed it up. Also write the output file in strips rather than scanlines and use TIFF predictive compression. Substantial performance increase. Refactor the code that reads FITS files to make it easier to understand and also use OpenMP. Only a marginal performance benefit. Major bug fix - calibration frames were either not applied or incorrectly applied when using Super-Pixel mode. Change DeepSkyStackerLive so that the choice of using the Dark Theme is controlled by the user settings. Display the FITS FILTER name in the picture list control, for information only at present. 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. Fix to correct problem where jpeg files were incorrectly identified as raw. When FITS file auto-detection is used, the CFA Yes/No display was incorrect - now fixed. Recommended Setting for Interpolation was incorrect. Fix for crash while attempting to select comet. Fix for Nikon Z 6, Z 7, and Z 50 being reported as unsupported. Clear skies, David
  4. Please note that DeepSkyStacker 4.2.4 has revealed a nasty bug in Photoshop (all the way from CS6 to CC 2020). The problem is that if you load a 32 bit TIFF written by DeepSkyStacker 4.2.4, convert to 16 bit and write the output to a new TIFF file, then that file is corrupt (to the extent that ONLY PS will read it). The problem was revealed by DeepSkyStacker's use of TIFF predictive compression which was enabled by the changes made for DSS 4.2.4. So as to inconvenience as few people as possible I have removed this from the soon to be available DeepSkyStacker 4.2.5. There's a couple of other fixes in there, but this is the main one. My apologies to everyone for any inconvenience that this may have caused. Clear Skies, David

  6. This is an update to the previous release candidate for DeepSkyStacker 4.2.4 that is built with the newly released LibRaw 0.20 to provide support for many additional cameras including the Canon EOS R (.cr3 files). Sadly there is problem with incompatibility between the new release and existing master calibration frames for more details see: https://groups.io/g/DeepSkyStacker/wiki/22443 (if anyone is wondering what happened to Beta 5 - it was buggy and I pulled it). The new beta may be downloaded from https://github.com/deepskystacker/DSS/releases/tag/4.2.4-Beta-6 The list of changes for this release: LibRaw updated to 0.20 providing support for over 1300 cameras including Canon Eos R (.CR3 files).

  7. Without access to you images, I couldn't even begin to guess what the problem is. If you wish to upload the images that are causing problems to somewhere like Dropbox or Google Drive, I'm happy to have a look to see what the problem might be. David

  10. Yes they do appear once you've loaded your images ...
  11. 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
  12. 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
  13. 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
  14. 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
