  1. I have a few queries re tiff files in DSS and hope someone can explain. Firstly, it took me forever to figure out that the autosave tiff file cannot be opened using normal editing software because its 32 bit. At least I think that is the case – maybe someone could kindly confirm. Second, when the final image is rendered on the screen, it seems to be quite dark. Of course this can be edited within DSS, and I’ve found stacking the RGB curves somewhere in the middle of the graph seems to get a good result. So then I save this file as a 16 bit image, and play with it in editing app. That works OK. But if I close the image in DSS and then re-open the 32 bit autosave file, it looks quite different to the way it was originally rendered. I also notice that the graph now looks like a straight line, rather than the original curvy line. If I hit the “reset” button, the curve appears as it did in the original, and if applied, the image then darkens to the same appearance it had in the original. I don’t know why this should be, but the key question is, if I reopen the 32bit autosave file, will this have the same data as the original? Or do I need to do all my DSS manipulation before closing the original file? I hope that makes sense! Thanks for reading.
  2. 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.
