20200208223150_IMG_0735.thumb.JPG.7cda037f7cf1bcb12d9742283aa668c8.JPGIm not exactly new to astrophotography but I am definitely new to stacking images. I first tried deep sky stacker because it seems it's what everyone uses. Almost every time I've tried stacking it only wants to stack 1 image cause of a star detection error. I made the detection threshold so it would detect the most amount of stars and it doesn't help. I read other posts and thought it was a focusing error on the stars so I made sure to focusIMG_20200403_132412.thumb.jpg.a45f870953308e575711cefd0250071c.jpg the image as much as possible and the error still pops up. The Orion nebula picture is one of a data set where I tried to stack and the error came up but the stars are very clearly visible. Any suggestions?

Hi and welcome to SGL.

DSS should stack your image.

It is over sampled and stars are fairly large when you look at them at 100% zoom level. It might be what is causing DSS.

One of the simplest ways to deal with that would be to tell DSS to use super pixel mode. Maybe try that first?

Alternatively you could upload your subs (if there is only 7 of them) to some file sharing service and people here can have a go at stacking and then tell you what settings worked for sure.

So I gave that a try and while it did stack the pictures the result was not very likeable I'll try to share my data files. There's over a hundred light files though the 7 were just a test.

Do share data as it could contain much more than meets the eye. Processing of stacked images is skill in itself.

Please make sure to export as 32bit (fits or tiff) as 16bit format can lead to some data loss if you stacked many subs.

      I have a huge problem with DSS.
      About a week ago, I took 300, 2 second long exposures of Andromeda with my skywatcher 90/900.
      But when DSS started scanning the stars in the images, it only registered about 5 stars at 40%. And only 7 stars at 20%. I tried to stack them and selected stack 100% of frames, but it only stacked around 29.
      I even tried it at 4% where it registered around 40 stars, but DSS crashed mid process due to the immense amount of stars being scanned (60 000 per image at least). 
      I tried it sooooo many times, but I don't get it to work. It somehow stacked 131 images I took of the lagune nebula (1 second lang exposure). You couldn't see the actual nebula, but some bright stars were there and DSS was able to stack. 
      In the Andromeda pics, there were like 5 times more stars, but it didn't work. 
      If anyone knows what's wrong, pls help me!!! I'm slowly loosing it on that nonsense.

      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. 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.  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. Clear skies

      Hey,
      I live in the NE of Scotland and have recently been bit by the Astrophotography bug!  I bought a Star tracker a few months back, but only started using it 3 weeks ago (due to crap weather).  The images posted are what I've managed to get with my Fujit XT2 and my various lenses.  Only just started stacking in DeepSkyStacker and trying to stretch / edit in Photoshop.  I've recently gotten the 45 day trial on Pixinsight so will be looking to try out editing in that.
       
      Looking forward to learning a bunch from everyone!

      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 more "night vision" friendly. 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. Update help files and add a new Dutch version of the help. Issue #83: Provide the option to perform NO White Balance processing at all (requested by Ivo Jager for StarTools). Fix for issue #42 - the stacking method "Average" wasn't always reported in the recap html file. Common control library 6 now used so some cosmetic changes such as filled progress bars.  Make the progress dialogs non-modal so that DeepSkyStacker can be minimised while processing. Update the DeepSkyStacker taskbar icon with a progress bar that matches the main progress bar. Saving of final TIFF file is now faster, and a number of other performance enhancements have been made. Ctrl-A will select all images in the file list (not the same as "Check All"). Del key will delete an image from the file list so you don't need right click and select "Remove from list" 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.

      When I stack with AstroArt 7 demo I get weird stars but I am sure I focused good. Why is that and how can I solve it?
