Astrophotographs displayed in this section are taken and composed by members of the Gibraltar Astronomical Society and are displayed with the consent of the artists concerned.
Terry currently uses an Explore Scientific 127ED refractor mounted on a Takahashi EM-200 Temma-2 Jr mount. The camera used is an SBIG STF-8300 Monochrome, which has an internal filter wheel. Mounted inside are all Baader 36mm unmounted filters - LRGB, Hydrogen-Alpha 7nm, Oxygen-III 8.5nm and Sulphur-II 8nm. Autoguiding is performed by an Orion StarShoot autoguider looking through an Orion 80mm guide telescope. Terry uses PHD2 for autoguiding and PixInsight for all image processing.
