The EVAL-AD5686RSDZ evaluation board is compatible with any Analog Devices SDP board, which can be purchased separately.įor full details, see the AD5686R data sheet, which must be consulted in conjunction with user guide (UG-725) when using the evaluation board. Note that when a microcontroller is used through the PMOD connection, the SDP board must be disconnected, and the user is unable to operate the ACE software. A PMOD connection is also available to allow the connection of microcontrollers to the evaluation board without the SDP board.

The analysis control evaluation (ACE) software is available for download from the EVAL-AD5686RSDZ product page to use with the evaluation board to allow the user to program the AD5686R.

The EVAL-AD5686RSDZ evaluation board interfaces to the USB port of a PC via a system demonstration platform (SDP) board. The evaluation board also incorporates additional voltage references. The AD5686R incorporates an internal 2.5 V reference to give an output voltage of 2.5 V or 5 V. The AD5686R operates from a single 2.7 V to 5.5 V supply.

This image shows my normal MaximDL windows set-up.The EVAL-AD5686RSDZ evaluation board is designed to help users quickly prototype AD5686R circuits and reduce design time. Finally, there are two windows from other programs overlaid on MaximDL - the FocusMax window, which enables automatic focusing of the image and the Status window of CCD Autopilot, which is controlling the entire system autonomously. The smaller window (to the left of the AO Control window) shows the image from the guide chip (you can see the guide star at the bottom of the image). The Image window (far left) shows the actual image (in this case, the Dumbell Nebula) taken by the main camera. The Information window provides data on specific objects (pixels) in the image, including star size and magnitude, average background noise in the image, etc.

Below the AO window is the Screen Stretch control, which enables setting the dynamic range of the image to actually be able to see objects (rather than all black, which is the normal starting point of most astronomical images). The AO control allows set-up and operation of an adaptive optics accessory (see "AO"), which can keep stars centered to within a fraction of a pixel (= a fraction of an arcsecond!). The camera window (far top right) controls the camera - set-up, exposures, and inspection of images). The following image shows MaximDL in action. This will correct for errors in the mount, but will not be fast enough to correct disturbances in the atmosphere. While the AO will work with magnitude 10-12 stars, the correction rate would be much slower - for example, once per second, rather than 10 times per second.

Therefore, the guide star exposure must be significantly reduced, thus requiring rather bright guide stars - typically in the 6-9 magnitude range. Today, using AO, corrections are made in a fraction of a second. In "olden days" (about 5 years ago, prior to amateurs having adaptive optics), scopes were corrected during exposures using a guide camera, but only making corrections once every few seconds. I could have selected a much dimmer star which allowed exact centering of the object on the main chip, but then the AO would have run slower, allowing less correction during a long imaging run.

Note here that in order to place the very bright star in the center of the guide chip, it was necessary to offset the globular cluster on the main imaging chip. Therefore, one must center the object AND rotate the camera so that a suitable guide star is centered on the guide chip, as shown on the image below. The brighter the star, the faster the AO can operate (up to about 30 times per second) - which allows partial correction for disturbances in the atmosphere (which is what makes stars "twinkle"). When imaging a very small field (at 3200mm focal length, and with my camera chip size, my total imaging field is only 15 arcminutes (i.e., 0.25 degree) square if it is desired to use adaptive opitcs to control the scope, a relatively bright star is required, and most small areas of the sky don't happen to have a bright enough star. When the image is zoomed in, the FOV indicator enables seeing what the telescope and camera will see - i.e., how big the field will be, where the object will be centered, AND - very importantly for a long focal-length (i.e., high magnification) telescope: the angle of the guide chip, relative to the main chip, and relative to the stars. The small reddish object in the center of the image above is the field of view ("FOV") indicator.
