Hello all! I hope you are well.
I'm trying to automatize spectra image. Usually, we need slew accuracy for imaging to get the object centered.
For spectra images, the star (order 0) must be uncentered (normally near of the left and botton corner) to get the whole spectrum in FOV. With my CCD and telescope, I have 39' x 27' of FOV.

I'd like to add and RA and DEC offset after de slew and before of imaging: (-9',-13')

Any idea how to add that offset?

Regards, and thank you in advance.
Rafa.
