A lot of additions were obtained from Scopestuff. Cannon DSLR prime focus.

The main telescope is a newer Meade LXD75 sn-10 10″ Schmidt-Newtonian on a GOTO equatorial mount. I have upgraded the stock focuser to a Crayford motorized focuser that is controlled with a remote. The price of the focuser was about $380. The addition of a Telrad finder has been very helpful in finding objects within a light polluted sky. A heated anti-dew strip is used as this scope can fog up quickly on both the outside and inside of the corrector lens. The CCD is a Meade DSI II color camera (USB interface) with Autostar suite, and it is being used as an auto-guider. A focal reducer is used often to aid in location and for wide-field views, as the DSI magnifies the image significantly. The main camera is a Cannon T3 Rebel.

Software: Meade AutoStar Suite with Envisage (CCD camera control), APT & Backyard EOS for DSLR control, and focus controller is operated by nFocus and Rigelsys.

The secondary telescope is a 1980’s Meade 6600 Newtonian reflector. Equatorial mount with no drive, it is used for quick observing and is also a loaner telescope for anyone at a star party to use. It does indeed have a lot of mileage – but it still works perfectly. It was purchased in 1987 at a Ritz Camera shop at the local Mall. The tripod needs replaced, as it is the legacy wooden one and is becoming unstable. It will soon be replaced by a modern Orion or Celestron GOTO mount. I sometimes do use it on the main Meade LXD75 mount.
