Nexus DSC Pro

After my Argo Navis broke down during my last observing session,  I investigated what to do to replace my Argo Navis.  I contacted Gary of Wildcard Innovations , but the problem was so severe that it was not easy to repair the unit.  It was also not so easy to send the Argo Navis back to Australia to have it checked.  As the unit was already 15 years old, I think it was the correct time to replace it.   I investigated the digital settings circle options that are available nowadays and found that besides the Argo Navis , the Nexus DSC Pro is another very good option.  I was always very happy with my Argo Navis, but the Nexus DSC Pro has some extra advantages, like a much larger database, an integrated GPS, an integrated Wifi module, it is very easy to upgrade the firmware of the device, easy to update the comets database, easy to add observing lists, ...  Due to these advantages, I opted to order a Nexus DSC Pro.  The order was placed on Thursday September 9, 2021, and sent on Friday

Observing Jupiter, Saturn, a bit of Deep-Sky and a broken Argo Navis on September 5 and 7, 2021

The beginning of September finally brought some very nice weather.  After I tested the Williams Optics Zenithstar 110 TMB APO , it was time to do some observations with my 18'' Obsession .   On September 5, I set up the telescope.  There was a high humidity, and the transparency was not so good, but the seeing was looking good.   When starting everything up, I got a strange error message on my Argo Navis .  The error message was something like ' SW Encoder Error'.  After restarting the Argo Navis, the same error appeared.  I tried restarting again, but the Argo Navis did not show anything anymore on the screen.  I could see that all LEDs were on, but nothing was visible.  After some investigations, it appears that there is a problem with the RAM of the Argo Navis.  It will not be easy to repair the Argo Navis and as my Argo Navis is already 15 years old, I will probably buy a new one or replace the Argo Navis with a Nexus DSC Pro .  Of course, this meant that I could no

Testing a Williams Optics Zenithstar 110 TMB APO with SkyWatcher HEQ5 mount

At work, we received a telescope from a colleague from the faculty of science.  The nice telescope is a Williams Optics Zenitstar 110 TMB APO on a SkyWatcher HEQ5 mount.  The telescope came with Baader Hyperion Universal Zoom 8-24mm , Baader Hyperion 5mm and a Baader Hyperion 3.7mm eyepiece. I first took the telescope home to do some tests.  In the beginning of August, I could use a Baader Herschel-wedge from a friend of VVS Capella to do some solar observing.  The view was nice, but the sun was not really cooperating...  The first day I observed the sun, there was only one very small sunspot visible.  At the next opportunity, there were no sunspots at all.

I took the telescope on holidays to Austria, but I could not find the time (and the good weather) to do some observing.  Luckily, on  September 3, 2021, the weather at home was really nice.  Even in the evening, I could observe i
