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.  by Terry Corridan
