12. on the planetarium program center the star then activate SYNC The driver goes into 3 star alignment mode on the 3rd SYNC that is if you are starting from 0 alignment stars Theoretically the driver can handle up to 1000 alignment stars would suggest that you distribute your alignment stars on both side of the meridian Avoid syncing or aligning stars at the meridian itself as the driver will block such operation Option to save the alignement data to follow Other added functions Sync Mode Check box This option if enabled will turn off all affine taki polar coordinate transformation routines The alignment stars will be treated as multiple localized SYNC stars The number beside the Sync Mode Check box shows which alignment star is currently being used as a localized sync data Debug AFFINE_TAKI POLAR Check Box temporary function This is enabled by default The eqmod driver will process all the alignment stars data using AFFINE TAKI POLAR coordinate transformation tests on my side actually shows better accuracy and less prone to centering errors If this option is disabled eqmod driver will use the old Affine Taki implementation This checkbox is valid only on the 3 star N star functions 35 28 Please check on your side and kindly report which option affine taki only or affine Taki Polar you think is accurate and less forgiving on centering errors You can also test the Sync Mode

15. OTH starts automatically If you start PHD first by doing it the way it works above just starting the program without starting POTH first then you can start CDC and hit connect to scope and it works no problem HOWEVER if you start CDC first and connect to scope and then try to start PHD by just starting the program as above you get the error message and PHD will not connect Like This By Starting Order POTH Connect scope OK gt CDC connect by POTH OK POTH Connect scope OK gt PHD connect by POTH NO POTH Connect scope OK gt CDC connect by POTH OK gt PHD connect by POTH NO CDC Connect by POTH OK gt PHD Connect by POTH NO PHD Connect by POTH OK gt CDC connect by POTH OK and POTH driver panel is running and visible SO if you are going to run both programs the only viable combination is to start PHD by just starting the program with POTH listed as it s driver and then starting CDC an just hitting connect to scope with POTH listed as it s driver in the preferences DO NOT start POTH first before any programs That s how it works for me anyway Hunter also discovered that POTH doesn t always close when you close PHD and CDC It hangs around and isn t even visible unless you hit Ctrl ALt Del and see it in the applications list found this out when shut down CDC and PHD and tried to restart things the right way PHD then CDC and immediately got an error message when trying to start PHD checked the applications list
16. X Y Delta method Let us know the results of the tests regards Mon What is N Star Alignment The latest eqmod driver now supports the 3 star and N Star Alignment algorithm See release details below 3Star and N Star basically is a mount stepper coordinate to Sky coordinate affine taki matrix transformation process The driver internally plots the sky using a minimum of three alignment star anchor stars as reference points You increase the pointing accuracy by simply adding more anchor stars on different parts of the sky This will automatically compensate any mount alignment errors polar cone etc and yield to accurate pointing http eq mod sourceforge net eqmod_3star html 3Star and N Star Analogy Think of the coordinate space of the mount eqmod as a rubber sheet with the star database marked on its surface You place the rubber sheet on top of a star map your sky and align the stars on the sheet with the ones on the map You then lock the sheet with push pins on top of the map The push pins are now your anchor points or alignment stars in the real world To align the markings on the rubber sheet with respect to the catalog points on the map means stretching rotating scaling specific areas of the sheet and locking them to the star map using the anchor stars push pins The affine taki matrix coordinate transformation routine is actually the one implementing the stretching rotating scaling functions and it
