DDM60 max weight for AP?

[YahooGroup]

Hi,

I'm considering buying this mount in the near future so I'd appriciate your
feedback.

Max weight for DDM60 is 28kg, but I'm wondering if the /2 rule for max weight
for AP use still applies to a mount in this price range? Or I can go higher than
14kg and still benefit the high performances of this mount?

Regards,

Sinisa Steblaj

Hi Sinisa

As long as you have good balance the DDM60 will be precise. I run the mount with
approx. 15 kg without any problems. I think it would carry much more if needed.
Precise balancing takes some time with this mount but thanks to the new autoslew
software version it is now really easy to find the right PID-parameters to run
the mount. This is a great piece of hardware! I have mine since about 6 months.
I don't want another mount anymore, but would like to get rid of all the other
small imperfections that come into play with this high precision like fixation
screw tension of my roll-out pier setup and such things.

The mount will do a great job once you have good balance and the right
PID-parameters as well as a good pointing model. The only time it became
unreliable was with imperfect balance and wrong PID-parameters but this was with
an old version of autoslew.

Hi,
I am using a C14 on my DDM 60 with a total weight of about 25kg.
With this kind of weight I found:

    Balance is critical
    It does battle to keep steady in windy conditions.

But, I have managed to get it working successfully, particularly after installing a dome to reduce the wind effect.

Hello Sinisa,

I'm using an Orion AG14 with 26kg(and not the 19kg annoucend in there site) plus
2kg of accessories and 26kg on the counterweight shaft.

And the balance must be very precise for a good PID values calibration.

Best regards,
Paulo Nunes.
