Hi all, First of all mine english is not so good so sorry for that. I am a new to astrophotography. And my setup is Mount : Skywatcher EQM 35 PRO Tube : Skywatcher Explorer 150PDS (newtonian) Camera : Canon 550D Guide scope : Svbony 60mm compact guide scope Guide cam : Svbony SV105 I know my setup is weak and cheap but for now I have them (budged problem ) I started the hobby at May and I took some photos that not bad for beggining. I reached 60-90 seconds without guiding. After that I thought that the time for starting improve the guiding and I bought guiding scope and cam. I know the cam is not for guiding but it was cheap, and I am planing to change it with mono guide cam (like zwo asi120 mono) at next months. But my first experience for PHD2 was terrible. I've detected some errors and tried to fix them. First thing there was a unbalancing. I mounted the guide scope on the position of finder scope which is very close to edge of the main scope. So I fixed it (after the night I tried to guide with PHD2) and put it on the bracelet (over and middle of the main tube) And second thing was that there is a backlash and I tried to fix it too. I opened to gear of dec and adjusted to gear mesh. Except them the alignment was not so good because location was in the city (bortle scale 9) and I haven't got finder scope as you know. So I am not sure that if the stars (3 star alignment method) are correct because with nacked eye I could't see them. Next time I will do better alignment with finder for sure. After them I am planing to try next weekend again. But before that I need your advises to eliminate the problems which I couldn't detect or I don't how to fix them. For example I can not see any pulse for RA on the graph what does it mean and how can I fix it. And also I am not sure if there is any problem with ascom. There is no option in the drop list for EQM 35 PRO. So I choose ASCOM.SkyWatcher.Telescope and I downloaded/installed ascom driver from webpage of skywatcher. Thank you PHD2_DebugLog_2020-09-21_100115.txt PHD2_GuideLog_2020-09-21_100115.txt
Hi. I am using PHD to guide my NEQ6 mount and have noticed a recurring issue. I have been trying to imaging the galaxies in Ursa Major and seem to have trouble getting it to guide correctly. It goes through the calibration stage (eventually) and says that it is guiding but it is quickly obvious that it isn't and eventually loses the guide star. When I set the target to something lower on the horizon (I am south facing), it calibrates and guides fine. Although I am using 5 minute subs, I get no trailing and nice round stars. Does anyone have any ideas? When I said (eventually), that is because I have to set the exposure time to 5 or 10 minutes just to get the star to move enough and reach the magic number of 25 which is set. Is there a way of reducing the 25 so that calibration can be acheived at a quicker rate or is it really a "magic" number? Many thanks in advance, Matt
