Attached are log files from trying to load a FITs file saved by ZWO camera software. The files load fine on other programs but when loaded into SGP I get an error “Object reference not set to an instance of an object”
The issue occurs right when I try to load a fits file, so the Time and Options isn’t set.

Ah, looking at the log file I see at access is denied.
[12/03/25 16:41:23.651][DEBUG][Main Thread][NONE] Error opening in CSharpFits (C:\Users\rschi\OneDrive\Documents\FITsImageToShare\Light_M 74_300.0s_Bin1_20251115-195919_0001 (2025_11_16 15_49_54 UTC).fit): Access to the path ‘C:\Users\rschi\OneDrive\Documents\FITsImageToShare\Light_M 74_300.0s_Bin1_20251115-195919_0001 (2025_11_16 15_49_54 UTC).fit’ is denied.
Any suggestions on how to fix this? I installed the application and I own the files as they are in my user directory.
thanks

I think I found a solution. The properties on these files has “read only” checked. While SGP is just reading the file I guess the O/S is blocking the open operation. If I open the file’s properties and uncheck the “read only” box then SGP can open the file. Strange, but I can deal with that.
Files that SGP generates open fine so I think future captures I do with SGP will be ok. These fits files were just captured by ZWO’s capture program.
Thank-you for pointing me in the right direction by showing me how to look at the log files.
