Dear colleagues, I´m tried to calibrate de SG-4 autoguide and I have some doubts: I follow the manual steps, in my case I live in the north of Spain LAT N: 43 12 00 , LONG W 3 00 24, Then I calibrate the mount with the Polarmaster and I went to Altair and I began to found the proper focus manually for the SG-4, when I saw it was focus , I abort "take images" and I put the focus running, I choose a star that in the center was 36240 (is this ok? or have I pick up a star with less value?), and the focus meanwhile was running, and running a lot of time, after I while (ten minutes) I decided to abort the focus I dind´t know if this process finish automatically or I have to stop myself, or if something is wrong, then I began the calibration (File attached) and when finished I start autoguiding (file is attached), but the result was poor. Is somebody clarify what I´m doing wrong??,I´m getting crazy with this!! thank you very much!
