Dew control

By -

As the humidity in Belgium is very high most of the time, I finally decided to buy a dew controller and a heater for the eyepieces, secondary mirror and the filter slide.  

Installing the Dew Controller

The Dew Controller I ordered is the Quad Channel Digital Dew Controller from Dew Control. The 2m long cable of the dew controller was too short to connect directly from the ServoCat power bar.  To fix this, a connector from the front of the lower cage to the power bar was installed on the telescope.

From the upper cage, I can easily attach the heater strip to the eyepieces.

Installing the filter slide with the Omega Dew Terminator

For the filters, I ordered a new filter slide, with the Astrocrumb Omega Dew Terminator.  The new filter slide has space for 4 filters: my Astronomik CLS filter, and my Lumicon UHC, O-III and H-beta filters. The fact that I will have space for 4 filters will already be a big improvement, as the H-beta filter is hardly used now.

Installing the secondary mirror heater

I ordered the Kendrick standard elliptical secondary mirror heater to keep the secondary mirror free of dew.  The filter is installed easily in the secondary mirror holder of the Obsession telescope.

Installing an ASA AZ800 in the observatory at work

On August 30, 2023 we installed an ASA AZ800 telescope in the observatory at work, at the  Institute of Astronomy  of KU Leuven .  The telescope will be one of the telescopes of the MARVEL project, an array of four telescope we will install on the Roque de los Muchachos in La Palma,  It was a very rainy day, but we managed to put the telescope in the observatory.  Enjoy some of the pictures!

Interstellarum Deep Sky Atlas

For Father's day, I got the field edition of the  Interstellarum Deep Sky Atlas .  In the past, I always used the first edition of Uranometria 2000.0 by Will Tirion, which was published in 1987!  I was always very happy with the Uranometria and I always preferred the first edition over the second edition.  I never took the book outside, but I made a copy of every page which I put in a sheet protector.  I took the pages in a big folder outside to starhop through the skies.    The Interstellarum Deep Sky Atlas comes in a nice sturdy slipcase. The last years, I mostly observed from home (Bortle 5), so I mostly observe bright objects.  Since last year, I added a SkyFI 3  to my Argo Navis / ServoCat so I can use SkySafari to always have a map on my phone or my tablet.  However, a real star atlas has a nicer overview, which is very useful when observing.  Under dark skies, a good star atlas is really needed to find the faintest objects. A nice card with the legend of the atlas The nice t

One observing night at the Roque de los Muchachos at La Palma

I was on La Palma from January 15 to January 21 for a technical mission at the Mercator telescope.  The weather was not very good, but I managed to get out the Orion Skyquest XT12i IntelliScope  we have in the Mercator building on the first evening I was there.   I forgot already that the sky is so unbelievably good from the Roque de los Muchachos.  There was quite some wind, but I could hide behind the car, so the wind did not disturb me that much.  The telescope has a right angle finder and a telrad, but the batteries of the telrad were empty, so I could not use the telrad.  Pointing the telescope with only a right angle finder is very difficult, so it was not easy to find the objects I was looking for.  It was quite cold, with a temperature of 2.3° when I started observing around 19h40 and a temperature of 3.7° when I stopped around 22h15.  The humidity fell from 57.5% to 33.2% and the wind speed was around 6 m/s.  I did not observe for a very long time, because I had to wake up ve
