  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
  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.
  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 o
  5. You can download it from: https://github.com/deepskystacker/DSS/releases/latest Here's the details of the changes in this release: 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 i
  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 ch
  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
  8. 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 F

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.

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.

  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 up
  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
  15. The first line of my post had the URL: https://github.com/deepskystacker/DSS/releases David
  16. 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. Add .rw2 to list of RAW file extensions. Change the colour scheme for DeepSkyStacker Live to make it m
  17. 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 wa
  18. 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). The code is now frozen unless bugs are found! This release is all about performance, though other areas have been enhanced as well. The main changes since 4.2.1 are: 1.

  20. 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).

  22. This new release fixes the memory leaks found in 4.2.0 It also speeds up the Median Kappa Sigma processing by about 20% compared to 4.2.0. You can get it here: https://github.com/deepskystacker/DSS/releases/tag/4.2.1-Release Clear skies David C. Partridge
  23. Please be aware that we've found a memory leak in the new code for importing RAW files in DSS 4.2.0. I've sent a test build to the person who reported the problem and will be releasing a fix in the form of DSS 4.2.1 Beta 1 fairly soon Apologies David
