MOTORIZE- ROLL OFF ROOF
Once I started using CCDAP4 for automating my imaging runs, it became quickly apparent for the need to automate the roof opening and closing . I used a modified electric hoist, gear motor to drive the the roof.
This system has performed so well over the years, I offer a motor kit package (modified motor + control box). For Details..............see link below.
MOTOR MODIFICATION WITH SPUR GEAR + BEARING BLOCK
I mounted the motor on a 1/4" thick x 12" x 18" steel plate.
Added a 1/2" x 1/2" steel bar with cap screws for fine adjustment of motor/ spur gear position.
COVER IN PLACE
Covered with matching indoor/outdoor carpeting.
Rack shown engaged with spur gear.
OLD CONTROL BOX & LIMIT SWITCHES
On the outside is a 5 amp fuse with a 0-5 amp meter to monitor current load. Opening and closing pulls about 3.5 amps. I installed motor limit switches on full open and full close to prevent any possible roof over-runs.
The near limit switch is for "Roof Close Stop" and the far limit switch is for "Roof Open Stop." The roof is in a midway position, so the switch trip cams are not in view. Also, note the ~2 " offset between both switches to avert trip cams from activating switches from the wrong direction.
NEW CONTROL BOX
The main reason for this project was to cleanup the old wiring and provide a design that could be fabricated and tested.If anyone is interested in this type of system and wants to interface with SkyRoof, Foster Systems, or m1OASYS Remote PC Controllers, I can provide this control box + the modified motor.
Two DPDT relays seen on the left, are used to automate roof opening and closing.

Interactive Astronomy- "SkyRoof" Remote Controller/ Relay Board
PC interface uses a direct USB connection to the controller/ relay board.
CUSTOM FIT COVER
Designed with quick hang-on hook/ hole & clip for easy access.
ROOF IN ACTION
Roof opening has (2) limit switch/ trip cam positions. The position shown is a partial opening when using the imaging scope only. This position still covers the desk/ computer, minimizing potential dew in that area. A full open position may be set to fully exposed my other scope for visual activity.
