AsiAirPro Guiding issues - Oscillations

xSky_watcher

Hello!

I recently bought myself an Asiair Pro and now after my first imaging session I've run into problems...

Somehow I have really strong oscillations (on both dec. and RA) that won't stop. Here's my guide log:

I think it instantly becomes clear where the problem lies...
Note that the first 2 logs of only a few minutes are not representative, those were only tests.
What usually gets said when someone's log looks like mine does they are told that their aggressiveness is set too high, which might be the case here, though I find it weird that I used those some values for agr. with my laptop (pre-asiair) and they worked like a charm. And as the Asiair uses PHD2 for guiding I figured my old settings would work, but this doesn't seem to be the case
Also, it's worth mentioning that the Asiair does no calibration (not even the first time I used it) when I click the crosshair/calibration/start guide button, so maybe (as has been suggested by other people) I have a setting turned on that takes the previous calibration.

Also, how can I change the MinMo (x/y) on the asiair?

Hope somebody is able to help 🙂

Clear skies,
Tim

Can not visit this link. Plz post again.

Sorry, there is no way to set MinMo on ASIAIR yet.

xSky_watcher Clear the calibration. Recalibrate each time you image, make sure you calibrate on the celestial equator. Follow up with your new results. Dont get wrapped up with phd2, you can get guiding to work fine on asir, learn to use everything available

also when guiding if you have issues after properly calibrating there are some things worth exploring. Guide exposure, aggressiveness, and guide pulse duration. If you have a belt drive mount there is probably very low backlash so you dont need long 1000+ pulses. If seeing is bad use 3-5s guide exposures. If you are getting strong oscillations, decrease aggressiveness and try to increase guide exposures. All this assumes you are balanced proper and have excellent polar alignment.

Thanks for the reply!
I will definitely try that out, thanks! Where can I find the setting to recalibrate?

The weird thing is that the aggressiveness settings worked fine on my laptop so I'm not sure whether or not that could be a cause for the problems, but maybe I'll have to decrease agr. indeed. Thanks 😃

I updated the link, should work now!

Oh okay, that's unfortunate.

xSky_watcher I think a peter zelinka youtube tutorial would help you familiarize best.
