PHD guiding
i have just tried guiding for the first time and i have run into a few issues. i use a QHY5l-ii with an orion 50mm guidescope and use autoselect to pick a star in PHD guiding. PHD does its thing, configuring and i get a green box, guiding has commenced. the issue is that i look at the worm and it is going a little crazy, fluctuating significantly above and below the line. i thought that this might be a Periodic error issue however it seems that the RA and dec line follow a very similar path. sometimes i can get guiding for about 60 seconds with decent accuracy, but at this point i think my unguiding is more accurate than the guiding. does anyone know what could cause this? does the camera need to be oriented in a specific way (RA slew goes perfectly horizontal) or is this indicative of a PE issue? thanks for the help.
