So today I decided to take a look at the Pulsar dome and its rotation problem. It transpired that the spring had stretched and was unusable that pulls the encoder wheel against the dome. I had to buy a 7mm spanner and I found a replacement spring in my workshop and fitted to fix the issue.
I then set about setting up the dome within TheSkyX (TSX)that I am now going to use only to run the dome. The way I have arranged this, as TSX does not have any connection to the ASIAIR, is that TSX connect to a simulator telescope and then to the dome. I then point the simulated telescope to the same object I am imaging with the ASIAIR and then the dome slews to the correct Azimuth. My home parked position is an Azimuth of 124º.
I set the dome geometry removing the settings I use to have for the 12″ scope Paramount MEII that use to be in the dome, replacing with the single figure that was needed for the AM7 with the Esprit 150, which was much simpler. A figure of 100, mm in my case. for the Xt value showing the offset from the centre of the AM7 axis to the optical centre. This seems to give me a good rotation so far. Over the coming nights I will test the accuracy and tweak if needed.
