My Fits file metadata displays the exposure duration of my images in the format "1.2000000000E+02", which converts to 120 seconds. Does anyone have a conversion table they can share or give a link to, so that I can easily make them into seconds? Thanks!
Hello, all. I acquired an Ultrastar C for EAA last fall. (I only got a few chances to use it over the winter, but we got some desperately needed rain instead. So that's ok.) The Ultrastar C has been astounding on the few evenings where the fates have yielded to properly working equipment and clear skies. I'm looking for pointers to tools and techniques for post-processing the color FITs image stacks captured from Starlight Live. I'm on a Mac so that limits some of the software options available. The docs for Starlight Live say there is a command line option ('-load-image-rggb') to reload a color FITs file into the program. Does this work from a Mac command line? Are there any other Mac programs that can read the Bayer RGGB color FITs files exported from Starlight Live for manipulation. Or something that can demosaic and export the files for manipulation in Photoshop? Maybe Nebulosity4. TIA. - Richard
Hi folks, Normally I process my raw files through DSS and then Photoshop but I thought I would try to improve my processing techniques using PixInsight This is a zipped Fits file produced by PixInsight v1.8 RC5 using the BatchPreProcessing script but to be honest I'm not even sure if the Fits file is a. processed through PI correctly and b. if it is, then I'm slightly bemused by the file contents and where to go with it. The rar file is a 150Mb download and contains a 600Mb Fits file so I fully understand if people shy away from playing with it. All of the images were shot on my Canon 7D and Canon 600mm f4 prime lens and the raw CR2 files were used. I loaded 30 x 240 second and 30 x 60 second lights, 20 x 240 second and 20 x 60 second darks, 20 x flats and 30 x bias frames into the script and pressed run and the zipped file was the output. I like to hear from anyone if they have any ideas on the correctness of the processing and what can be achieved with the Fits file. Using DSS to stack the images, a few PI functions and PS I have got this image from the data
Had a quick search but not found much info, I've just 'transitioned' from DSLR to a CMOS (AA 183C pro) Used to capture with APT or Backyard Nikon, save as RAW, DSS to stack and use autosave.tif to work on in Photoshop. Whats the general consensus on CMOS ? So far trying APT or Sharpcap, saving as FITS, stacking in DSS still and using autosave.tif into Photoshop. I keep seeing fits liberator mentioned ? Opinions gratefully received.
Hello. This is my first post here and I wish to introduce a little program i wrote. This is a RAW to FITS batch converter. Converter supports many cameras vendors: Canon, Nikon, Pentax, Fuji, Konica, Hasselblad and so on. May be useful for someone who shooting space with DSLR and wanna do a real science, search for variable stars for example. Program is very simple (see attached screenshot), you just set input directory, output directory and few conversion options. You can choose how to process color channels from the RAW file. Possible options is: - convert RGB to avarage grayscale - store all three channels as separate images in a one FITS. - store all three channels in a separate FITS's - store only one selected channel Converter supports multithreading conversion, depending on your cpu/cores count. All data you entered in UI will store in FITS header. Some data (like exposure, date and camera model) may be acquired from the RAW file, this is preferable. This is a free software licensed under GPLv2 license. You can get it on github: https://github.com/olegkutkov/Raw2Fits Program uses libraw library and i highly recommend to get latest stable version of this library instead of using your distro version. If you have multiple LibRaw versions on your system - please carefully check which version you linking and using in runtime. Correct Makefile if needed. Libraw version older than 0.17 may not correctly extract EXIF data from the RAW files. Also you will need cfitsio, any version is Ok. User interface is built with GTK3 toolkit and tested with Gnome 3, Mate and Cinnamon DE on different Mint, Debian and Fedora distributions. After executing 'sudo make install' command this program should appear in your Applications menu Hope this program will be useful for someone. I will be glad to hear your feedback, propositions and bug reports
