Wykrota Observatory - CEAMIG - 859

Ceamig-Rea Observatory – I77

Equipment – Software

• LX200 – 12 inch• CCD - ST7 XME and optec 0.33 reductor • Telephoto lens – 70-200mm• CCD – ST-402• Robofocus

Software

• ACP 4.2• Maxim – 4.53• FocusMax

Observatory Control - Hardware

• Project based on microprocessor PSoC from Cypress

• Serial port control, protocol based• Controls:

– 12 generic switches (10A, 250V) – 4 on/off contacts (rolloff closed/opened, etc)– 4 analog inputs (temperature, humidity, rain

sensor, etc)

Observatory Control – Software

• Microsoft .NET library (DLL) with COM (ActiveX) and .NET interface

• Developed in C#• Event based or Pooled control

Observatory Control - Hardware

LCD Display (for debugging)

Humidity Sensor

Serial Port

PSoC Microcontroller Programming/Power

(for debugging)

Potenciometer (analog

simmulation)

Temperature Sensor

LEDs (load switch simmulation)

Switch (contact simmulation)

TAO – Tools for Automated Observers

• Astrometry of solar system objects (including confirmation of new NEO candidates listed on the NEO Confirmation Page and follow-up and recovery of minor planets and comets)

• Searches for new solar system objects • Photometry of minor planets, comets, variable

stars, etc. • Supernova searches • Nova searches• Follow-up of Gamma-Ray Bursts (GRBs)

System requirements

• ACP + Maxim + Pinpoint• The Sky + CCDSoft + Orchestrate

• The author can develop a special version of TAO image acquisition script for another set of programs

Initializing TAO

• Modeling slew times• Measuring camera download times• Specifying filter numbers and names• Modeling the local horizon• Creating user profiles• Create Target databases

Image cycle time

Modeling telescope and dome slew time

Tools for creatingand maintaining Target databases

Creating and Maintaining Target databases

Automated ephemeris update• Download of new ephemerides for objects whose orbits

have been updated since the time when their most recent ephemerides were downloaded.

• Download of new ephemerides to replace expired ones. • Download of ephemerides for newly discovered unusual

minor planets and comets. • Download of ephemerides for known unusual minor

planets and comets which have become observable since the last update of the moving object database.

• Customizing ephemeris update
