Hi Robert yes I turned on hpt for the tests (I also tested without hpt and got better results, as before). The idea with the PID paramters not being correct is...
Hi Frank Most probably oscillation - I agree. Not sure where the oscillation comes from thou. I would love to check your suggestion out, but I am not sure even...
Hi again Philipp, yesterday I was really tired from traveling so there was one thing in your collimation answer I did not reflect upon. Now when I have slept...
Hi Geoff, I have my mount on a permanent set-up with AC power access, but as far as I have understood it the mount can be used with deep cycle batteries. The...
Hello! On the side of Philip Keller he wrotes: After an upgrade it can happen that you get an error like "Automation error …" or "Could not connect to...
Some more questions regarding the install of new sw 1. After installing 5.0.2.2 according to the instructions on the web site (first de-install Autoslew and...
Thank you Stephan, I solved that problem by upgrading the ASCOM platform as suggested by Robert. I have installed the last Autoslew version and it seems to...
Frank, thanks! - I found it. Not sure what it does but I will try to change it and see what happens. What are normal values for these parameters? Just in from...
Hi Geoff, Just got my DDM60 in South Africa (SH). 1. Yes, I did initially use a battery 2. Others have done it, and I will report back in a few weeks....
the original definition of collimation error is indeed not the one you mean but it came from measuring with Theodolites "The optical axis of the telescope,...
Philipp with that understanding of collimation, I definitely see that it is important if you want to model the set-up. I promise not to check it "un-used"...
Hi George, I am not sure how to figure out which ring to adjust, but I guess it should be possible to find out if the optical axis is too low or too high, by ...
Sorry, one more thing. If collimation is defined this way, it should only affect pointing (especially after making a meridian flip), but not tracking. In the...
... thats true. However its not only influencing pointing when doing a meridian flip but instead the error only applies in Right Ascension and is proportional...
please read: http://www.astrooptik.com/asa/AutoslewInstallation.pdf I will try to find a better way of determining the DDM60 Encoder Resolution soon, I have...
Hi Guys, I finally have all the bits and pieces for my DDM60 and busy setting up. I have done the balancing and set PID values. Cloudy, so cannot go further. ...
Hi Dale The problem with the camera rotator should be fixable. The imbalance arises because the centre of gravity of the camera (and any attachments)is not on...
Hi Dale, If the mount becomes jerky at some part of its movement you haven't got the PID values right yet. Keep experimenting. It should be possible to find...
Hi Dale, see my suggestions to answer/comments below Hi Guys, I finally have all the bits and pieces for my DDM60 and busy setting up. I have done the...
Hi Matts, How do you ensure that it remains in the park position when the motors are powered down? Dale ________________________________ From: Matts Sporre...
Hello Dale, Once your mount is powered down, nothing insure you that it will stay in the park position because there is no security brake. It is a known...
... Dale, if you balanced correctly the bearings retention forces will hold your equipment in position - you usally won't even need a rehome or sync to...
Hello! I have some questions to Mr. Kellar. We are trying to use DDM85 to track satelites on geostationary transfer orbit. We use our own software that...
