Placed my solar filter on my guide scope with the purpose of focusing the scope for approx focus for guiding stars. I got it to focus nicely in yawcam yet when I moved it over into PHD it appeared way out of whack. I tried adjusting everything down and still couldn't obtain a sharp focus. Probably just the built in parameters for PHD, however when I moved it back to yawcam it failed to recognise the original focused settings changed back manually. What I did notice though was that if I blocked out an additional 90% of the light it appeared to focus. Is it a case of the CCD getting hot despite the filter?
