Add "CCD-TEMP" to Image Header of Master Calibration Files

Calibration frames captured with SharpCap include a "CCD-TEMP" field in the Image Header. It would be nice to see this field included in the Image Header of master calibration files as well. This is especially helpful for master darks.

Would also be nice to see temperature included in the master file name.

Thanks in advance,

Nikko

Is this temp tag always the same between subs? If that varies slightly, it may be tricky to include. But I forwarded your rfc to Mabula, thank you!

edit: And got word back that it's something he indeed wants to add in a future version.

Excellent! Thank you so much.

Yes, I believe the tag is the same for all subs.

As an example, this is the Image Header for one of my dark subs captured with SharpCap:

+1 for this addition too.

very useful. 
I use APT for aquisition, it always populates this field correctly.
