Hi,

 

does your RA axis spin free and smooth when you have no scope attached? Does the axis feel uneven when you rotate it?

And just to rule out simple issues: are the clutch fastening screws/rotation limits unscrewed (see product manual page 13)?

 

Best regards,

 

Robert

Ask ASA for a remote session to identify the problem

Hello

I guess my problem is of the same nature. My mount ASA DDM60pro (serial no. 10110, production year 2012) makes the mistake on RA axis while using at low temperatures. The lower the temperature the more faulty exposures. Worst effects are observed in temperatures below freezing. In fact I am unable to take any pictures in such weather conditions. I can feel greater resistance on the bearing then. On the other hand, during spring while the air temperature exceeds 8 degrees Celsius, mount works without any disruptions.

My two colleagues from Poland have experienced exactly the same issues and it appears the production dates of their mounts are the same as mine.

I have performed two tests on my mount DDM60pro. First took place on 15th April 2015 and night temperature was 12 °C then. I haven’t observed any issues during taking photos. I did second test on 21st April 2015 and temperature was lower on that day: 6 °C. I noticed two exposures with errors:

  • 1st exposure 600s, dated 21-04-2015, time: 23:09:51
  • 2nd exposure 600s, dated 22-04-2015, time: 00:23:49

Below you can find photos taken on the same day during bad exposures at 600s as well as CIServoLogs file. For clarity I am providing a selection of CIServolog lines where tracking errors have occurred.

-23:01:28 error 2.41 arcsec  7.3A

-23:01:40 error 2.87 arcsec  5.0 A

-23:01:46 error 21.85 arcsec  5.0 A

-23:01:58 error 21.42 arcsec  5.0 A

-23:02:04 error 84.91 arcsec  5.0 A, end of exposure 1 - 23:09:51

 

-00:15:11 error 1.77 arcsec  6.2 A

-00:15:28 error 2.13 arcsec  3.8 A

-00:15:40 error 2.71 arcsec  4.9 A

-00:15:47 error 10.27 arcsec  5.0 A, end of exposure 2 - 00:23:49.

 

Best Regards

Andrzej

Hi Andrzej,

 

To me this sound like a mechanical problem, which can only be solved by ASA.

I would contact them and make an appointment to send it back and have it checked by them.

You are probably wasting time and get frustrated by trying to solv this yourself.

 

Just explain to problem to them and let them solve it.

 

Best regards,

Waldemar

Hi Waldemar,

 

At the beginning of April 2015 I have reported this issue to ASA. I was asked by them to send CISerolog file with the record of faulty tracking of my mount DDM60. I have sent them the CiServolog 2015_4_21 file (attached to my message above) as well as the pictures on 26th April 2015. To this day I have not received any reply to my query. Later on I found out that there are other Polish colleagues who experienced exactly the same problem with ASA mount DDM60. That's why I decided share my story on this ASA message board.

 

Best regards,

 

Andrzej

I have very good experiences with contacting Dietmar Weinzinger, Andrzej. (d.weinzinger@astrosysteme.at)

Please try it, This takes almost a year now... I really admire your patience, but the problem should be solved.

Thanks for your story, it's the same problem and the same temperature. someone has solved the problem? 

It is not just that it takes so long to respond it is not a Chinese mount or the price of a Chinese mount.

Hello Waldemar,

 

Thank you for your advice. I have reported my mount DDM60 issue to Dietmar Weinzinger on 07.04.2015. He redirected me to ASA support department and I sent them all relevant log files and pictures. I will perform one more test and send them the results again. 

 

Best Regards

Andrzej
