Hi there, very new to astro but have just started using a dedicated ASI183MC colour camera with my ASIAir. I can stack the lights no problem in SIRIL with excellent results but when I use the script to process with calibration frames (flats, darks and biases) the script fails because it says the images are different sizes. A quick look at the fit files suggest this is because the lights are recognised as 3 channels but the calibration files as only one. I know they have been captured as colour images but the program does not seem to deBayer them. Is their a meeting that can address this?
There are two possible issues there.
- You have indeed color images, so already debayred, and in this case you can’t do nothing, it is too late. At least for a correct preprocessing.
- With the ASIAIR,j if you take some images, like flats for example, not in the same way you did with lights and darks, it is possible that the files have not the same size. Indeed, for an unknown reason (to me) the ASIAIR changes the file size. So you MUST record all your images in the same way.
Hi, have checked the file dimensions and they are all the same for group and there are no extraneous files in the folders. When I check the individual files with SIRIL the only difference is that it identifies the lights as 3 channel and the calibration shots as single channel. I assume I am missing something simple somewhere in the process.
Share a file if you want but I’m afraid your images are already demosaiced.
Thanks for having a look at the problem, I think I have found the issue, definitely user error. Found a fit file hidden amongst the lights that did not belong. Thanks again

i’m new to this hobby and just got a ZWO ASIair Plus 256, i have gone out several times and have attempted to stack in Siril 1.4.0beta 2. i can not for the life of me stack any thing (i can stack RAW images, but ASIair is not saving the RAW files to my DSLR). i get an error immediately when using the OSC Preprocessing script. as you know ASIair creates FIT files, does the Siril script allow for those? it appears not, to me anyway. i have my FIT calibrations in appropriate folders and the only way to stack for now is to useASI Studio and take it’s final FIT file and process in Siril.
Hello,
Of course siril can stack FITS files. I would encourage you reading a bit our tutorials on or the documentation.
Starting a new hobby implies to learn some basics.
Our tutorials detail, step by step, how to proceed.
Then, after that, you could share your console logs.
