Turn the Optec MaxFilter off and on then reboot the Apogee computer Follow the procedure to start up Maxlm and instrument initialization If the problem persists go to the CCD Control Window in Maxim and choose the Setup tab Click Shutdown it will ask if you want to turn off the cooler choose Yes and click on the pulldown menu next to the Filter button in the Setup tab Select No Filter None and click Restart to restart the CCD camera You will have to click Cooler On again as well Now filters will have to be changed manually by using the Optec MaxFilter filter selection paddle upstairs 3 I pushed the EMERGENCY STOP button and when released the telescope keeps trying to move Push the EMERGENCY STOP button Hit ENTER on the MOVE computer to abort all current commands Once all commands have been aborted pull the 12 EMERGENCY STOP button back out You can now proceed to move the telescope 4 pushed the EMERGENCY STOP button and when released the telescope does not move when given MOVE commands Hit ENTER on the MOVE computer to abort all current commands Reset the motor drives by flipping the rocker switches on the motor drive controller cables until the drive lights are rapidly flashing green You can now proceed to move the telescope 5 cannot get all three speeds on either the upstairs or downstairs console to work If you are using the upstairs hand paddle make sure that the downstairs control console is set o2. Before starting a sequence of images you should check that the number in the Start at field is correct or data files may get overwritten 10 e DX ES DU de eo Shutdown Procedure Save all data and select the Setup tab of the CCD Control Window in Maxlm Click on Shutdown When it asks if the cooler should be turned off click YES Exit from Maxlm and port data over to TITANIA Double click on the Network Neighborhood icon on the Windows desktop Select TITANIA from the Network window and choose the folder to place your data in If Windows prompts for a password type 2wallace Select the folder containing your data and drop the folder into the folder youve selected in TITANIA Once the data is on TITANIA the data can be retrieved from campus by mounting TITANIA Once the data is ported over successfully shut down the Apogee computer using the Start button in Windows Turn off both downstairs monitors Close the dome and replace telescope cover Turn off the Optec MaxFilter and Apogee camera Exit out of MOVE by typing qu at the command prompt It will ask if you really want to exit follow the instructions to exit Type exit at the DOS prompt and Windows will start Shut down the MOVE computer using the Start button in Windows Turn off the monitor SPRINT as quickly as you can downstairs and turn off the power strip to both computers The MOVE computer has a tendency to restart on its own about 10 seconds after shutdow

5. the telescope can continue to move in declination The telescope cannot be moved in HA beyond that point Moves can be made only in the opposite direction until the limit is no longer triggered 2 Horizon Limit The horizon limit will trigger when the telescope tube is parallel to the ground When MOVE is properly functioning the telescope cannot be pointed below the horizon When the limit is triggered MOVE will stop all telescope motion Telescope moves away from the horizon limit must be made with the upstairs hand paddle while the limit override button on the upstairs control console is held down until the limit is no longer triggered NOTE If MOVE is malfunctioning for some reason the horizon limit may not be triggered properly and there is a chance that the telescope could be moved beyond the horizon to hit the floor of the dome You should visually check the telescope position whenever the dome needs to be moved 3 Focus Limits When either focus limit is triggered the focus mechanism will stop The focuser cannot be moved beyond that point in the direction of the limit Moves can be made only in the opposite direction until the limit is no longer triggered Using Maxlm Focusing the Telescope 1 Take an image of the star that will be used to focus See the Taking Images section below 2 Click on the Focus tab on the CCD Control Window in Maxlm 3 Turn off the Dark control Turn on the Continuous mode to take a series o

14. r the Inspect tab shows a narrow peak the FWHM values are as small as possible and Max is as large as possible Note that the Max value will usually bounce up and down due to seeing when close to focus you should take the best of several readings Taking Images 1 OP ON m Bring up the Settings tab of the CCD Control Window and check the settings Maxim CCD Click the Reset button to make sure the entire CCD chip is selected Set Binning to 1 for highest resolution To enable a beep at the end of each exposure turnon Audible Alert Set Auto Calibration to None To save the telescope coordinates in the FITS header of the images go to the View menu and select FITS Header In the header window type OBJECTRA in the Key Name box and type in the RA as displayed on the MOVE monitor in the value box Then type OBJECTDEC in the Key Name box and type in the DEC as displayed on the MOVE monitor in the value box You can do the same for other Key Names that do not appear in the FITS header window NOTE You must remember to update the telescope coordinates in the header file if they have changed before the exposure is saved to a file Usually it is a good idea to do this step before the exposure is taken The date and time of observation as well as the exposure time do not have to be changed manually The date and time of observation are taken from the computer clock which is synchronized to an NTP server so make sure the Apogee
