Shelyak Dome Tracker for Observatory Domes
The Shelyak Dome Tracker was designed to allow automatic movement and closure of an observatory dome that is already outfitted with motors. The Dome Tracker is inserted between your computer, which is being used to control your telescope and other accessories, and the controller for your dome motors. Once installed, Dome Tracker can send a signal to open or close your dome based on your inputs. You can also have your dome mimic your telescope’s movements during Go To and tracking.
There are two different modes the Dome Tracker can work in, depending on what type of roof you have on your observatory; "Dome" or "Roll-Off Roof".
- DOME: If you are using Dome Tracker on a dome, this mode will rotate the dome to find its zero position and then positions are tracked with an angular encoder. Shelter is managed by a signal sent to your system.
- ROLL-ROOF: Use this mode if you have a roll-off roof, and Dome Tracker will send a signal to your motor controller until the end-of-position switches are activated.
A Guide to the Dome Tracker Connectors
RS232 Interface: Your PC will connect to the Dome Tracker via an RS232 serial interface. Drive the Dome Tracker via an ASCOM driver or directly from a program like Prism version 6 or 7 (not included). This software will allow you to control your telescope and your dome for continuous alignment between the two during computerized object location and tracking.
Sensors: Encoders keep the Dome Tracker system appraised of your dome’s location at all times.
Motors: Connect the Dome Tracker to your dome rotation motor controller. Dome Tracker will tell your motor whether it should go right or left.
Open: Open or close the dome with a signal from Dome Tracker.
Emergency or Urgency Interface: This is a special input dedicated to a weather monitoring system or an urgent stop command that tells the Dome Tracker to close the obervatory.
The Dome Tracker requires a 12V Power Supply (user supplied). The Dome Tracker includes internal relays for electrical isolation.

- Questions & Answers
Product QuestionsDo kit can be used to telescope MEADE LX600 STARLOCK? and do Kit can be used to any dome? . and do you have send to Bogota-Colombia? thanks.Question by: Luis Gomez on Mar 14, 2015 11:34:00 AMThis kit has an ASCOM driver and the Meade LX600 can also be controlled with ASCOM through a Windows based laptop. The problem occurs because the dome will usually rotate slower than the telescope mount can move, so the Starlock will fail the alignment as it will immediately try to take a picture. If you drift align, set up the alignment model without the dome or by quickly moving the dome manually so that the dome slit always lines up with the Starlock when the mount stops moving, and then hook up the motors and this Shelyak controller with software that allows you to delay the mount move (start moving the dome first and then tell the mount to move 15-30 seconds later) - it may work as long as the dome and LX600 remain synched at all times.
This kit can be used on most ASCOM controllable domes like the ones from Technical Innovations, Explora-Dome and others.
We can ship this internationally, but it is a special order and thus not returnable without a restocking fee. Please contact us by e-mail at email@example.com with questions.Answer by: Chris Hendren (Admin) on Mar 17, 2015 5:46:00 PM
