GreenLine Roll-off Observatory kits by Dome Parts Optical are cost-effective and ecologically friendly DIY alternatives to observatory domes. Made in Germany, these roll-off kits are extremely simple to install as they do not require specialized tools and are supplied as a flat pack.

The GreenLine MEDIUM-32 is spacious with a floor space of 2.25m x 2.25m. The ample space has enough room for telescopes up to 14" along with optional tables, workbenches and shelf storage. The base configuration includes a user friendly manually-operated dual slanted roof and folding rear shutter.

 

 

GreenLine observatories are available in a range of sizes to suit single small telescopes to multi-scope remote installations. Optional semi-automatic roof drive systems for all Mini, Medium and Big roll-off observatories are available, as well as full ASCOM-automation configurations for remote control over Ethernet and USB. All Greenline observatories have pre-installed cogrim gears, pulleys and counterweights. The roof drive system can be easily added and is as simple as inserting the motor unit.

Greenline observatories are fumigated but the wood is not treated. As these observatories have been delivered all over the world, Greenline recommends using the proper treatment specific to the types of pests found in your local area.

 

 

Power considerations

The best solution to power the motors of Greenline observatories is a 12V DC battery using thick cabling (we suggest 6 AWG) and Anderson Powerpole connectors capable of up to 50A. Alternatively, industrial-grade 12V DC switchmode power supplies will also work.

You can use up to 15V DC (for example lithium batteries) but once you drop too much below 12V, torque drops off dramatically.

RC-33M belt drive draws 40.8A (only ONE motor can run at the same time with one shutter engaged)

Roll-Off observatories roof drives draw 18.5A when opening and 14A when closing.

Both control units are polarity protected - the units do not work when plus and minus are swapped.
