Telcon Solar Image Map

Telcon Solar Image Map


As currently implemented, this is a recent Halpha Full Disk image from the Singer as supplied by the Macintosh once an hour. Eventually, we plan for the Macintosh to be able to continuously supply a source of recent images which will be loaded into Telcon either on demand by the user (see the Load Image button), or automatically, every 15 minutes by the program. If for some reason, the software that gets the image, resizes it for display, and puts on the grid, fails, you will just get a grid with Lat. and Long. lines every 10 degrees. Once the Macintosh has the ever-ready supply of current images, when you see this grid, you will be able to simply click on the Load Image button and grab a new image that hopefully doesn't contain the same problems that the failed image did.

The orientation of the Image is marked with an N on the north pole and a W on the west limb. The time and date the image was captured are displayed in the upper left and right corners, respectively. The image is Pangle corrected since the observer makes this correction on the Singer setup.

The yellow X on the image marks the current pointing location of the telescope. It is updated every time the telescope is moved, either by hand with the hand paddle, or through the Telcon GUI. A future plan is to have the 10 most recent pointings (as in the History Menu) also indicated on the image with another X and perhaps a number, with 1 being the most recent pointing and 10, the least.

At the start of each new observing day, the last picture of the previous day (or a grid) will be displayed while the current image is being loaded, processed and displayed. Note you must be running the Full Disk Singer camera on the Macintosh in order to be able to get the most recent images.

You may click anywhere on the image to pop open a Move Requester with the X and Y coordinates of the point you clicked on. Note, you can also do this for regions outside the solar disk. Also note, that since the image is Pangle corrected, and the real Sun is not, the generated coordinates may not look like what they should appear were the image not Pangle corrected.

Once the move box is up, you may continue to click on different regions of the disk and the move coordinates will update accordingly, or you can hold the (left) mouse button down and move the mouse around the image, with the coordinates continuing to update until you release the mouse button. Since you can select either Move or Cancel, you can use this feature to generate X and Y coordinates of various features on the sun for reference.

You may also edit the coordinates displayed by hand, if you choose, prior to clicking Move just as if you had brought up the requester by hitting the New button next to the Cartesian coordinate display.

Since the loading of an image takes some time, two different messages are displayed in the Message Area during the process. The first one, Working on loading a new solar image.... means that the process has started of getting an image from the Macintosh and making the necessary changes for display. This is just to let you know that the image load is in progress, so you don't re-click on the Load Image button, getting impatient waiting for the image to load. (Although if you do get impatient and request a new image multiple times, you will get an information requester telling you to be more patient in various different ways....) The second message, Loading the new image. The GUI won't respond until it's loaded. means the image processing has finished and the image is now being loaded into the display. Since the load process takes a few seconds, the GUI will be unable to respond to your actions during the load process.

The point and click capabilities of this GUI feature should make it easy to move the telescopes to any region of interest on the sun, relatively quickly.
