Rejection rate

4zEkIAY8

I get very high rejection rates (70-80% rejected) on my S50 in spite of :

Level sensor properly calibrated, then level is <0.5.
Compass calibrated
Latest firmware (3.68)
AF done with Bahtinov mask
Imaging a target rather high in the sky, and no meridian issue.
Bortle 3-4
Horizontal calibration performed successfully
Goto works immediately.

What can explain the high rejection rate ? I thought it was due to the previous faulty firmware, but now I know it's not.

Thank you for your help !

4zEkIAY8 Do you do this all the time or occasionally? May I ask how long you have been shooting to obtain images for how long?
Seestar stacking failures are related to a variety of factors including wind, ground vibration and other environmental factors.
If you are shooting close to the zenith, the rotation will be more severe, which can also lead to stacking failure.
It is also recommended that you use the default exposure time of 10 seconds, longer exposures can easily result in stretched stars.

Hi
I see this all the time. Yesterday evening f.ex. I obtained 48mins of accepted frames for 2h20 total time, so 66% rejection rate.
No wind and 10sec exposures, always.

Please submit your logs through this tutorial： https://h5.seestar.com/course/79221 (Remember to check “Add log”) We need your observation information, so please don't turn off your computer after the observation, we will analyze the logs to find out the reason for the high rejection rate. Thank you for your cooperation.

Thank you, I will do this next time I use it.
I understand I can only send the log after using the telescope and before shutting it down, correct ?

4zEkIAY8 Yes， This is so that the S50 can record your data for this shot.
