Finally, after a 5 month wait, the 2.5" Feathertouch focuser arrived for the AT10RC. Full focal length, 2000mm, AT2FF, HEUIB-II in the Nikon D5100.
Got out tonight for some initial testing. Nine 600 second exposures @ ISO 800 on a star field just south of Almach.
Guided with PHD2 at basically default settings. Looks good from my house..:)
