Hi!

Yes, it would be very good if the CRVAL keyword where in the fits header - for example, SpecINTI relies on this for computing atmospheric extinction.

I was surprised to see it in your header, because I was under the impression that Ekos did not produce it at all. Now, looking through my own photometric images, I do find it there too. But not in my spectra. For photometry, the main camera does the platesolve, for spectroscopy, I have a separate "positioning guide scope" doing it - in its own imaging train. So I do not use the guider for platesolve, never worked for me due to small FOV with my C8 and C11.

What version of Kstars do you run? I'm using 3.6.4 stable on Stellarmate.

Concerning the StarEx: I have indeed printed it myself, and also the Lowspec that I use (first bought one second hand but decided I wanted to print it myself). After beginning with 3D-printing I actually no longer understand how to do amateur astronomy without a printer jokes aside, it takes some time to acquire skill sufficient to print a good spectrograph but it is not very difficult. But if you don't want to print, there are commercial sources that can print for you. Or maybe some other amateur - ask on the Sol'Ex mailing list What kind of spectroscope du you currently use?
