Greetings nMAC,

Unfortunately, no solution for these problems so far. I also have the same problems (frame dimensions won't save and camera freezing after exposure stops). I also had a problem with guiding here: indilib.org/forum/ccds-dslrs/10106-probl...n-guiding.html#74868 . Fortunately, the problem was solved by installing the latest SDK thanks to the useful advice. Fingers crossed if we can have a solution to the problems arising here. I noticed that Kstars on Astroberry (3.4 edition if I remember well) didn't have these 2 problems with QHY.

Guiding problem solved by installing the latest SDK. Thank you again. I kindly ask you to see another problem with dimensions and camera freezing when exposure stops, here: indilib.org/forum/ccds-dslrs/9289-qhy-cc...imensions.html#74840 . It seems a bunch of us have the same problem.

Best wishes.

Greetings,

Thank you both for your answers. I installed 21.08.05 and I will test tonight.

Best regards.

Greetings, QHY driver communication has gone really bad. Yesterday I tried to run my QHY as a guider (as usual). Everytime was starting, guiding froze and QHY didn't respond. I couldn't work guiding so I ended up doing some unguided captures that didn't go well. I attach the log file. Its pretty big, so please use search with keyword "qhy" to see the problems. I kindly ask you to give it a try and let's see how this problem can be solved. Bad QHY driver communication slowly gets on my nerves and I am really thinking of changing this camera if we don't find a solution. Too many problems ( and new ones),unfortunately without a solution so far. QHY is a real disappointment in building drivers for INDI. Thank you very much for your time.

Best wishes,George

Greetings again Alessandro. That seemed to be the solution. Plate solve worked great after unchecking the option. Thank you very much.

Best regards.

Greetings Alessandro,

Thank you very much for your suggestion, I have noted it down. I have never changed "use scale" option tho,it was enabled everytime PPA worked fine,so why would that made PPA fail?

Best regards.

Greetings. Today I experienced a problem with stellar solver trying to begin my astrophoto session with PPA. Yesterday and the day before yesterday, PPA worked fine. Today without changing anything, PPA refused to work properly and I didn't change anything. I usually do offline plate solving with the default Stellarsolver options. Default options didn't work so I try literally everything (default,small-largescale,online astrometry,high exposure time,high settle,everything - except local astrometry which gave me a EKOS crash the last time I tried to test it). I attach the logs and various photos to match the time with what Ekos was watching. Yesterday I managed to do PPA with fainter and fewer stars than today (attached photo). I can't really understand what happened today.

Thank you very much!!

Greetings Jasem,

Thank you very much for your reply. The problem was here: indilib.org/forum/ccds-dslrs/9289-qhy-cc...rame-dimensions.html

I get an invalid frame request (0,0) (can't remember the exact words now) but that doesn't seem to be so crucial. I keep capturing and guiding even with this error message. The problem appears when I stop and need to continue.

Greetings. I have a problem with my QHY CCD camera (QHY 6). I experienced the problem with many versions of Kstars being patient that the problem will be fixed. I guess it's a problem with QHY drivers from QHY itself. I connect my camera. At first everything is fine,I capture,loop and guide without a problem. But if I need to stop capturing/guiding and want to begin again,QHY does not respond to my actions. It gets stacked,doing nothing and sometimes it disconnects by it's own will. Even if I disconnect everything and reconnect them again,disconnect cables and reconnect the again, nothing gets fixed. I have to completely close Kstars and start all over. You can understand how frustrating is this when you are on the field. Do we have a potential solution of this problem? Thank you very much !!

I attach the logs.

Georgios Lekkas replied to the topic 'Internal guider questions' in the forum. 5 months ago

Greetings guys, I want to ask a question about total error. What is the difference between a total error of 1, 2, 5 or 10 and so on for examples? What really happens to the mount and how is the pulse we send being used? The value of the total error is being multiplied with a number x arcseconds? Thank you very much for your time. Sorry for the "google questions" but I cant really understand what is the happening. I hope plain explanation from fellow observers will help me. Thank you a lot again.

Best regards,
George.

Greetings Alessandro,

I don't think 20 degrees will be a problem. I have done it with 15 and I had a dead center plate solving. Just keep in mind NOT to hit "done". Just stop the process,switch from west to east and the opposite (based on which direction you begin) and start the process again. You may need to do the process several times based on how much error you've got. But be patient. Wish you the best.

George.

Greetings Jasem,

Thank you for your answer. This is the only thing I can think of. Maybe I had put almost at its maximum azimuth knob range from the start and as a result I couldn't make adjustments. I noticed that the azimuth adjustments go east side so I will max out the azimuth knob to have plenty of range to go to. If not today,tomorrow I will check again and update this post.

Greetings PORKYHTTP,

When I start the polar alignment lets say for example west,30 degrees, and the error is too high,I adjust the knobs until the star I picked moves to the corner of the image in the direction of the lines (as closer to the hypothetical crosshairs as possible). Then I don't hit "done",I just hit "stop",and go to the opposite direction, east,30 degrees. I repeat this sequence until I have the crosshairs in my image. Last night I made a foolish mistake when clouds cleared for one night the last month angry.png.

Best regards,
George.
