Main equipment is a C11 telescope on a Losmandy Titan mount with Gemini II controler. I recently updated it from Gemini I (and from origonal motors to Maxxon ones) - a huge improvement in pointing accuacy.
I connect in PRISM using ASCOM driver but connect to POTH (Ascom hub) from PRISM and setup the Gemini.Net within POTH; this seems more stable and works fine.
Here are my parameters for the Gemini.Net:
Here are some function I use in the script to control telescope:
CONNECT_OBSERVATORY Valid : connect telescope/dome
STOPTELESCOPE : stop tracking
CLOSE_TELESCOPE_DEVICES
The telescope is installed in a 2.7m Pulsar dome; I have a Dome Tracker to control the dome and PRISM interface with it directly.
I use OPEN_DOME and CLOSE_DOME in my script. I also use "DOME_SET_CONTROL 1 1" to ensure the dome is always in synch with the telescope.
I have two GemBird computer controled power plugs so I can switch equipment ON/OFF by using the Power Manager software that comes with those; I just run as an external program in my script, a nice PRISM feature; for exemple:
EXECEXTERNAL "C:\Program Files\Power Manager\pm.exe" "-on -Device3 -DomeTracker"
For the (echelle, fiber fed) spectrograph, I use a Velmann board that is handled in PRISM as a switch. Here are the functions I use for this:
Switchdesired=1
GETSWITCH Switchdesired nbSwitches ArrayName ArrayState
SETSWITCH Port1 ON
The script starts with a begining sequence that wait for the Sun's elevation; when right, it connects to the equipment, cool off the main CCD camera, runs the calibration and then starts the observing sequence. At the end, I just close equipment and dome.
To find my next target (which is repeated all night), I use a catalog of Be stars that I create in an Open Office Calc. It uses a robot file created every night in BESS database (through ARASBeAm website) that list for each Be star when it was last observed and what is the expected observing period (usually 365 days). I calculate from this a BESS priority but add my own priority too.
The catalog only list ~200 objects which are bright and isolated as my strategy is to center the brightest object in the guiding camera.
The guiding camera is a Zwo ASI174MM (a recent update from my old Atik Titan which I had lot of trouble with specially with latest Atik drivers). The field of view is great and it works very well.
To find the brightest object, I acquire an image, save it in FITS and JPEG format, bin the image 4x4 and look for brightest star:
StartExposure_EX 1 GExpTimeChamp
WaitForEndExposure_EX 1
GetLastImageExposure_EX 1 ImgChampToCenter
sFullPath$=sDirSave$+"ZWO_ASI174MM_"+Object$+"_tocenter.fits"
SAVEFIT ImgChampToCenter sFullPath$
sFullPath$=sDirSave$+"ZWO_ASI174MM_"+Object$+"_tocenter.jpg"

BinX=4
BinY=BinX
BINNINGREDUCE ImgChampToCenter BinX BinY
BRIGHTEST_STAR ImgChampToCenter MinDynamiqueAutoguidage MaxDynamique MaxOmC PSFMin DemLargFenCentro ZoneRecherche XGuideCentro YGuideCentro
I had hard time to find the right parameters. I bin so the star are not too large and so the running time is acceptable. The MaxOmC parameter can be found when doing a centroid on an image; having it too low reject some actual stars; I use 2000 as a value now and it works.
To center the brightest star, I calculate the shift in RA/DEC. If it is close enough to the fiber ole I just start the autoguiding but if not I recalculate RA/DEC so repointing the target to recenter it.
MOVETELESCOPE AlphaNew DeltaNew
WAITFORENDMOVETELESCOPE
There seems to be a bug in Gemini.Net ASCOM because if I ask for a GoTo to the same position I ask before, it fails and goes wild. SO I have a two steps approach by pointing a position close to my target and do a second GoTo after. Even for recentering the object I am doing this two steps approach and it works.
Autoguiding is run with a single function, autoguiding needs to be predefined before in PRISM:
STARTGUIDECONSIGNE NumCam CCDNum GExpTimeBis DelayACQSec WindowSize CentroSize StarThresADU AgressRA AgressDEC RaMin RaMax DecMin DecMax Backlash CurrentDEC AlarmEnabled DeltaMoveFashion GuidePosX GuidePosY SaveImagettes DirSaveImg$ AllFrame WindowAllFrame Valid message$
Note that I am checking the hour angle, so the distance to meridian in order to stop my acquisition sequence before I cross the meridian too far.
I also run some statistics on each raw spectra image to avoid saturation and allow night to night comparison. Those are displayed and saved in a log file as well.
At the end of the target acquisition, I recalibrate the telescope on the object coordinates as it moved during the autoguiding sequence:

Here is a link to a Youtube video taken during a full session. No comment but you can follow the observation as it progress...
Here is my current code which you can of course freely use for your own private use:
/////////////////////////////////////////////////////////////////////////////////
// //
// OTZ_Auto - Script to observe automatically (c) Olivier Thizy //
// //
/////////////////////////////////////////////////////////////////////////////////
//
// Some specificities to equipment used:
// -Losmandy Titan mount (upgraded witrh Maxxon motors & Germini 2 in 2019)
// Connected through Gemini.Net + POTH (mandatory for PRISM to work properly) with 2.5sec regular readout (idem)
// -echelle spectrograph with Velmann board to control calibration lamps
// -observing bright Be star as primary (only!) focus
// -Atik 460ex for spectra acquisition
// -Zwo ASI174MM (was Atik Titan) for guiding
// -Dome (controled by Dome Tracker)
// -RoboFocus
//
// Brief description of the algorythm:
// -I wait for the Sun to be below some limit (bsed on experience)
// -First I create my night's directory, copy/paste my usual CALIB files (master darks, current version of script...).
// -I connect my equipment (note that I usually switch my Power Manager ON manually because it's not stable,
// I also connect my cameras and my telescope manually because PRISM/ASCOM seems to be unstable there.
// -I lower the temperature of the main camera and wait for the Sun to be at a certain elevation.
// -I acquire (if necessary) my calibration frames for the night: a long serie of Tungsten for the blaze of the echelle spectrum,
// three LED to get the geometry of the echelle orders and three Thorium-Argon for wavelength calibration
// -I wait for th Sun's elevation to be at the level that allow observation to start
// -I load my catalog file which is created by an Excel spreadsheet where I import BeSS robot file;
// in a nutshell, the catalog file lists my ~200 Be stars targets with catalog name for PRISM to use, magnitude
// (used to calculate the guiding exposure time), the BeSS priority based on required observing period and last observation date
// (I also take into account if I have observed it myself as BeSS takes time to be validated/updated sometimes),
// a bonus priority for my favorite targets or current hot targets, individual exposure time and number of exposure to acquire.
// -Then I enter a loop for the night:
// >based on telescope position, and excluding targets below minimum elevation (40°), crossing the meridien at mid exposure
// (I always observe in the East part of the sky) and below a DEC limit (just because my pointing accuracy there is lower),
// I select my next target (of course, one that has not been observed that night so far)
// >I point the telescope to the target, wait for the dome, center target (brightest star) and then start the autoguiding
// (if no star is found, I try an astrometry and if not possible then I wait 5min with telescope tracking stopped)
// >then I start the exposure until the target is crossing the meridian or I reach the required number of exposures
// or if the Sun elevation if above the limit to end the observations --> then I go to the end of Session
// >and I loop to go to the next target...
// -End of Session: I stop telescope, I close the dome, I increase the temperature of the main camera, I close all equipment
//
// After a session, I reduce all my spectra using ISIS, the clean up all the intermediate files, create an archive and a ZIP file with
// all my spectra to upload them in BeSS database... and I wait until the sky is clear for next session!
// BUGS / ROBUSTNESS (TO DO)
// ------------------
// -improve mechanical holder for the dome sensor (ie: spring to be improved)
// -Goto with WaitForDome option failed sometimes: removed from script for now / to be checked
// -replace USB by LAN gembird: hardware ready when needed, not critical for now
// -pb with telescope connexion (hardware?): done manually for now, to check again ?
// -pb with Zwo ASI that sometimes freeze (USB link to improve?)
//
// WEATHER MANAGEMENT (TO DO)
// -------------------
// -rain detection -> wiring to dome tracker + software test to stop telescope & close everything else
// -calibrate Sentinel cloud sensor: seems very difficult to find the righ parameters, need more work on this
// -wait for good weather: tested but failed; need to be improved
// -check weather: pause
// -multiple pause: close equipment
// -sentinel relay script activation
//
// IMPROVEMENTS (TO DO)
// -------------
// -when a target not found, skip it (could try later? limit to 3 retries total?)
// -add list of targets done during last few nights to add to BeSS priority calculation (to limit same target several nights)
// -automated ISIS data reduction with Actiona external tool
// -at the end creates a simple web page with guiding image, last ARASBeAm spectrum graph and our Halpha graph
// -catalog of bright isolated stars or astrometry on the field
// -goto with star hopping or astrometry on the field
// -improve simulator mode to take into account elevation & distance to meridian at time of observation (targets.txt mode)
// -add management of star to Synch at the end of a session to "park" scope
// -split start & calib & directory setup
// -search for object$ to avoid local/global variables
// -add the ability to do calibration at the end in case weather is bad at the beginning of the session
// -check disc space at the beginning
// -add to the ARASBeAm priority calculation my own observations (not validated in BeSS yet) to avoid always doing the same targets
// -add fainter target with an astrometry mode
//
// REVISION HISTORY (WHAT HAS BEEN DONE)
// ----------------
// -05/08/2018: first "stable version", target list inside script, some bugs (telescope connexion, USB Gembird, first autoguiding).
// Lack weather management, good target catalog, star hopping method for large GoTo, etc... some comments in french.
// Based on brightest star in the field, very specific to my own equipment. 60 Be stars spectra (Halpha) acquired so far with the script.
// -15/08/2018: add printed info when star lower than HauteurMin; read targets from an external text file; simulation & total exposure time calculation
// Some functions to read a Be star catalog with BeSS priorities, my own priorities & calculate a weight to sort stars by interest. Seems to work ok.
// -19/08/2018: fix of the displayed hor angle (calculated on target and not from telescope position)
// -09/09/2018: automatic check if calibration is done; simulation removed (always done, user can stop script if he wants),
// calibration, goTo and download time added in time for session calculation, directory naming/creation done at beginning
// -15/09/2018: first test of automatic target finding based on catalog file (BeSS priorities still manual),
// elevation of the Sun calculated for end of acquisition (not begining), if object$ is not recognize: skip target,
// automatic guiding exposure based on Vmag, automatic scheduling based on priority & time allocation
// -17/09/2018: correct end of night bug with Sun's elevation calculation on limit hour angle calculation
// -27/09/2018: fixed starDeltaRA calculation when telescope close to 24h, fixed AngleHor calculation in CheckStarCatalogForVisibility
// -07/10/2018: fixed end of observersion date and add DateFrac test (Sun elevation after midnight!)
// -09/10/2018: improve stop observing time Vs begin time to avoid trying to observe too late...
// -23/10/2018: limites après méridien fortement diminuée pour éviter les pertes de GoTo
// -15/02/2019: alphaplus=alpha+0.005 (au lieu de -0.005 avant) pour améliorer le pointage
// -02/06/2019: modifications following Gemini 2 upgrade; no pointing model in Gemioni 2 or PRISM for now...
// -03/06/2019: adding AskForManualAutoGuiding option as it doens't work in PRISM with new ATIK drivers !!!
// Removing of recentering of the brightest object in the field as it doesn't work anymore in PRISM with latest update :-(
// -16/06/2019: replacing Atik Titan by Zwo ASI 178MC guiding camera
// -22/06/2019: replacing guiding camera by a Zwo ASI 174MM, added several comments & cleaning the script file
// -23/06/2019: added SHIFT_TELESCOPE to recenter the target and it works!!!
// -24/06/2019: added a two steps approach for GoTo & reecentering (due to a bug in PRISM/POTH/Gemini.Net chain somewhere...)
// Add couple of log files with stats
// -30/06/2019: switched to OTH_Catalog2 with MyName added (target list name with spaces). Checked several bugs that I can remove:
// >sometimes fails at first autoguiding, root cause not found yet, didn't happend with Zwo ASI174 so ok...
// >end of night, dome disconnected? didn't happend for long time now? seems OK...
// >at end of the night it doesn't stop early enough, need to revisit how scheduler works: better since early 2019 - ok...
// >sometimes it tries to go to a target but it is too close to meridian, loosing 5min each time (improved in eartly 2019) - ok...
// >stop telescope tracking while waiting for next target, done ok
// -07/07/2019: added an astrometry search in case target is not found (to be improved to gain time)
// >catalog file read for each target (so can be modified even when script is running)
// >if star is already close to the fiber hole, no need to recenter it so skiping it then
// -13/07/2019: BINNINGREDUCE (instead of SCALE) 4x4 for BRIGHTEST_STAR
// >add FIND_ALLSKY_POSITION (with binning 2x2) when star not found
// -14/07/2019: Move astrometry search at beginning of each target GoTo
// -17/07/2019: move back to brightest star in the field as astrometry isn't reliable yet... Pb with Gemini.Net more than PRISM scripts at the moment...
