Hi all,
Some success.
Below;
1) Spec, full width frame, during slew. -no stars in spectra
2) Full raw frame minus dark, no stars in spectra
3) VSpec results.
The mask is on the wrong side so I had to mirror the frame
. Easily fixed by rotating the mask by 180deg.
Focus is much much more difficult.
Only 1x7sec exp for each
As for .tar, maybe somebody with linux could open them and resave as .zip. Big job I imagine.
