Ray created a new topic ' Comparing PHD2 and Internal guider.' in the forum. 2 years ago

Hi, I've been using Kstars for a few years now. And guiding with my EQ6R Pro has always been a weak point. Using the Internal guider with default settings I'm seeing RMS rarely drop below 1 and the plot shows the mount move quite erratically. Quite often i see imaging terminated because guiding drifts too far. I've always put this down to my equipment as my 10" Newt is pushing the mount to it's documented limits. The other night I switched from Internal guider to PHD2, again with default settings, expecting to see similar results. I was surprised to see no more erratic behaviour and RMS figures in the 0.3 to 0.5 range. Is it possible to get similar results from the Internal guide? I've played around with the settings and PPEC many times but never seen this kind of improvement.
