Integra RF80 combined rotator focuser. Good condition, working well, just tested. Rare and very useful item for software controlled focusing and rotation of your camera using the one unit. Will work well on large cassegrains, RCs or refractors that have sufficient backfocus (ideal for your GSO RC with a suitable adapter). Includes 2” Baader camera connector and large ~80mm SCT thread adapter on telescope side. Very solidly made and weighs 1700g.
Comes with Lunatico Seletek serial controller, serial cables, USB and 12v power lead. Utilises ASCOM software control. 80mm internal clear aperture. Focuser has 2.4 micron resolution at full motor step.; 1.2 micron in half step mode, with 9mm focus travel. Rotator has 9/18 arcsec per full motor step resolution,; with 1.5Nm unbalanced torque. Minimum backfocus 62mm.
These RF80s are now out of production but sold new for about 1300 euro. Reluctant sale, but I do not have an imaging scope now that has sufficient backfocus so it is surplus to needs. Selling for $1150 plus postage. PMs only please.
Thanks for looking
