Thanks guys , I bought a new QHY guider with 3 micron pixel size and a high resolution . I tried the OAG but it is proving too difficult becuase finding a guide star is a challenge, then the stars are never round and then once I find the star it wobbles immensely and PHD goes crazy . Because the Celestron is a big instrument along with the dew shield attached any slight wind shakes it making it difficult to guide on an OAG. Any ideas are helpful but I do have the permanent pier in concrete and a High resolution small pixel guider so hopefully that will suffice .
