Moonshed Posted January 8, 2018 Share Posted January 8, 2018 Last year I started taking images using a Cannon 1100D and my Celestron. I downloaded and used DSS v. 3.3.4.0. It worked just fine and I got some (for me) decent pics. This week I took 25 x 120 sec subs at 800 ISO of M42 to compare with my images last year. The settings I used are RAW+L and sRGB. DSS is refusing to play ball and just keeps giving me this error message when I click on "Register checked pictures". "The checked pictures are not compatibles (width, height, number of channels, only one master dark offset and flat)." I have not to my knowledge altered anything but can't be certain. I notice that in the DSS info box where all the image files appear that in the column headed Depth all my lights are described as "gray" while the Master dark and flat frames are "RGB." I don't understand that as reviewing the images in the camera they are all showing nice peaks in each of the RGB curves and the images look good. Please help, it's driving me nuts trying to figure out what is wrong. Link to comment Share on other sites More sharing options...
mikeyj1 Posted January 8, 2018 Share Posted January 8, 2018 I have had lots of trouble with DSS and my 1300d. One suggestion, go back to one step at a time: Lights only and stack. Add Darks, but dont re-register. then continue..it helped me find out there was a problem with my bias/offset files for some reason good luck!

happy-kat Posted January 8, 2018 Share Posted January 8, 2018 The lcd shows the jpg files it is not the raw directly, and it is normal asfaik for dss to show gray against your lights. As above I'd try lights only first. Link to comment Share on other sites More sharing options...
Moonshed Posted January 8, 2018 Author Share Posted January 8, 2018 Thanks guys, much appreciated. I did as you both suggested and loaded only the lights and to my surprise that worked perfectly normally and produced a nice image ready for processing in PS. I don't know what it means though, is it that somehow my Master Dark and Master Flat have both become corrupted? How do I move on and add the master files as you suggested? Just as a matter of course I am going to redo both master files anyway, can't do any harm. Link to comment Share on other sites More sharing options...

No, the focus was good throughout and I always start each session by focussing with the Bahtinov Mask. Each individual image when viewed is in sharp focus.

michael8554 Posted January 8, 2018 Share Posted January 8, 2018 The files displayed as RGB aren't the Raws, possibly the L's you also shot? Michael Link to comment Share on other sites More sharing options...

Michael Yes, thank you, from what I have gathered that does appear to be the case, also the fact that DSS is happy to process just the lights does strongly indicate there is not a problem with them. The problem only arises when I add in the master darks and flats. I am going to remake the masters to see if that solves the problems. Fingers crossed.

Moonshed Posted January 9, 2018 Author Share Posted January 9, 2018 I have redone the Master Dark and that now works fine with my Lights. When I added in the Master Flat it again gave the error message so clearly the fault is on my old Master files. If conditions are suitable I will remake the Master flat tomorrow and then I will be fully back in business. Thanks for your help, Link to comment Share on other sites More sharing options...
catburglar Posted January 10, 2018 Share Posted January 10, 2018 Check the dimensions of your flats / darks- I seem to remember that mine changed by a few pixels when I went from RAW+L to RAW only..... If they're not the same as the lights I think DSS won't use them.... Link to comment Share on other sites More sharing options...
Atreta Posted January 10, 2018 Share Posted January 10, 2018 When i had that error, if i remember correctly, was due to having a jpeg file in the middle of my added raw files,. I think you can't mix them in dss. My notebook just died so i can't test it again. Link to comment Share on other sites More sharing options...
