I found that the tracking of my ASA DDM85 mount started to show some deviation. I therefore recorded a few pointing models this night and then performed polar alignment. The result was that, for the … Read more
I started with comet and spectroscopic observations, unfortunately i sam some condens on the CCD-chip of the telescope for comet observations and i must interrupt the observations for comets. I could going on with the … Read more
a USB remote control unit was added to the LHIRES-III spectrograph to remotely control the calibration lamp and flat lamp. Information can be found here.
a clear night after 2 weeks of clouds and rain. First is must rebuild a complete pointingmodel for my ASA mount, due a softwarecrash. After that i could obtain some comets: 29P/S-W1, 31P/S-W (dubious detection), … Read more
I received the 0.4-m primary mirror back from Orion Optics without any charge. This is very professional of Orion Optics to help me with this problem. I tested the mirror with Foucault an ronchi and … Read more
The C11 telescope was send to Ralf Ottow for check and improving the collimation and optics. He checked the optics and he said that this C11 was better then C11 median telescopes and one of … Read more
I removed the AG16 telescope for maintenance and search for the cause of the collimation issue – the telescope was more then 3 year i use without any clenaing of the mirrors. Also the collimation … Read more
I noticed the last observations that the tracking isn’t smooth anymore in RA of the ASA DDM85 mount. I checked the balance again and noticed if the telescope is on the other side of the … Read more
SQM meter gives no data anymore, also the all-sky camera is out of service. After some troubleshooting, it seems a bad contact on the nRJ45 connector of the SQM-LE meter and could fix that. The … Read more
There seems to be problems with my AAG cloudwatcher. The rainsensor gives always rain and the IR-sensor is sometimes clipping to 0 degrees. Jaima send me the new sensors and i’m going to try to … Read more
