    3232'''Please Note''' - VNC uses port 5900 to connect to a computer. If too many people are connected at once, this can cause the connection to run slowly. Make sure you disconnect when done for the night. And if someone else is using TMO please limit the number of connections to what is required. Zach will occasionally go through and kick lingering connections on port 5900 (during the day).
     33== Using the webcams ==
     34
     35There are two webcams in the dome, one looking at most of the dome (it can be steered), and one looking at the telescope dials (note that only HA and DEC will be correct, not RA which depends on a clock!). They are accessed using the Internet Explorer (only!) browser by going to the addresses tmocam.nmsu.edu (dome/telescope) and tmocam-wireless.nmsu.edu (dials) using the browser on the TMO desktop (which is actually Microsoft Edge but running in Explorer emulate mode for these addresses). The user is admin.
     36
     37Use these generously! They have built-in LED lights that you can turn on. These shine at ~8000 A, so can even be on while you are taking exposures, unless you are working in the I band.
     38
     39If something does not look right in the webcams, stop! In particular, if the telescope does not appear to be pointing where the coordinates in the software think it is, you should stop, to avoid running the telescope into the limits.
     40
     41Note that the dials tell where the telescope really is, not the software!

    3443== Start Up from an Empty Desktop ==
    35 We usually keep the desktop set up, however there are times where the desktop might be blank. If you are starting observation from an empty desktop (please inform Zach E of this) and follow these steps:
     44
     45Usually, software is left running. The software consists of:
     46- !FocusMax v4 : focussing software
     47- MaximDL : camera control software (science and guider)
     48- Scitech controller : telescope controller
     49- ACP : master control program
     50- Clarity II : weather station program
     51
     52If all is up, check the Scitech controller program to confirm that it says "Scope Parked". If it says "Not initialized" or "Bad scope communication", then the program may need to be restarted, and the telescope position will need to be initialized
     53(for now, contact Jon or Zach).
     54
     55If you are starting observation from an empty desktop (please inform Zach E of this) and follow these steps:
    3656
    3757* Open '''!FocusMax v4''' using the desktop icon
     
    4161* If doing manual observations - in ACP go to both '''Telescope''' and '''Camera''' to connect both the telescope and camera
    4262
    43 == Using the webcams ==
    44 There are two webcams in the dome, one looking at most of the dome (it can be steered), and one looking at the telescope dials. They are accessed using the Internet Explorer (only!) browser by going to the addresses tmocam.nmsu.edu (dome/telescope) and tmocam-wireless.nmsu.edu (dials) using the browser on the TMO desktop (which is actually Microsoft Edge but running in Explorer emulate mode for these addresses). The user is admin.
     63== Dome Control ==
    4564
    46 Use these generously! They have built-in LED lights that you can turn on. These shine at ~8000 A, so can even be on while you are taking exposures, unless you are working in the I band.
    47 
    48 If something does not look right in the webcams, stop! In particular, if the telescope does not appear to be pointing where the coordinates in the software think it is, you should stop, to avoid running the telescope into the limits.
    49 
    50 == Dome Control ==
    5165The Dome Control is done via ACP (note, '''NOT''' ASCOM Dome Control). In the ACP control box - in the bottom left click the button - '''Dome Control''' to access the controls. Once you open the dome - it will open the dome slit and then slew to the telescope, so beware! Make sure the telescope isn't pointed somewhere you don't want it to be, e.g., in the direction of the Sun!
    5266
    5367== Slew to an Object ==
     68
    5469Slewing can be accomplished through the ACP program, which provides a deep sky catalog and various bright stars, or through the Scitech telescope controller. The "Nudge" window in ACP allows you to offset the telescope in any direction.
    5570
    5671To go to an object - in the bottom left of the ACP box, click '''Slew or Sync (catalog)'''. This will bring up an option to allow you to slew the scope to a given object. There are four options:
    5772* Coordinates (RA and Dec) : note, however, that ACP does not seem to take J2000 coordinates in the slew window. To slew to coordinates, you may need to use the Sidereal Technologies telescope window Goto tab, with the J2000 box checked
    58 * Deep Sky Object : can be entered by name, but note it ispicky about spacing in Messier and NGC catalog '''M 44''')
     73* Deep Sky Object : can be entered by name, but note it is picky about spacing in Messier and NGC catalog '''M 44''')
    5974* Major Planet
    6075* Alignment Star: set of bright stars, you need to know your constellations to know where they are!
    6176
     77There is also an ACP !FindBrightStar script: use Select the Script in the upper right of the ACP window to find it, then click the Run button in the lower right. After starting up, it will prompt you for a filter to use, which you will enter in the Console window: here the filter is specified by number, 2 will use SDSS r.
     78
    6279== Taking exposures ==
     80
    6381You take exposures manually using MaxIm DL, using the Camera Control window (the icon to the left of the observatory icon). Use the Expose tab, where you can set the filter and the exposure time. The science camera is Camera 1, while the guide camera (no filters) is camera 2. The guide camera is mounted on the 6" finder scope and is pointed in about the same direction as the main scope/camera.

    7088Manual focussing using Jog window in FocusMax... Windowing and continuous imaging with MaximDL
    7189
     90Automatic focusing with the !AutoFocus script in ACP.
     91
    7292== Scripts ==
     93
    7394There are several scripts in ACP (for example, auto focus) which can be very useful. These are located in the ACP box in the top right - click on '''select the script...''' and it'll open a list of scripts that you can run.
