Hi!

I'll try to explain my issue as simple as possible:
I'm doing spectroscopy. To center my object, I have a guidescope with a separate camera. This is the one doing plate solving.
Then my imaging camera sits on the spectroscope. This one does NOT plate-solve.
So I have 2 scopes, so to speak, with 2 camera. I have set up them as 2 image trains. Only common feature is the mount.
Not my issue:
Lately, seemingly since I upgrade to this version of Kstars where image trains is a feature, I no longer get date and CRVAl keywords in the fits header of my imaging camera. That makes sense to me -if we now consider that independent from my centeringscope/guidescope. But it becomes a real problem in processing the images, since atmospheric extinction is very important for spectroscopy.
So: is there a way for me to get these important keywords in images from BOTH cameras/both image trains? Maybe I can set up the centering image train in a way so that it does not become independent from the imaging camera....(but I can not figure out how). Or can I use some script to insert the keywords in some way? This is really a serious issue for this processing.....

And I can't say I understand the logic. One could think that since they share the same mount, information about where that mount is pointed (CRVAl keywords) should be inserted. And I don't understand why the date and time is not inserted anymore. The Fits header from one of my recent main camera images is here:
