The first SX Spectrograph was introduced in 2016, but was intended for local operation, where the user could change slits, focus etc., by hand. The market has since evolved to include many remote observatories, well beyond the direct reach of the observer, so we have now automated most of the spectrograph functions. The Spectrograph PRO allows you to change slits, adjust the imaging camera focus and wavelength setting, and switch on a calibration lamp, or flat field lamp, remotely.
The New Ultrastar PRO is the Lodestar PRO’s big cousin. Higher resolution and twice the active area combined with similar low read noise and high QE. The Ultrastar PRO is an outstanding guide camera as well as a fantastic outreach/introductory camera.
