Observing session May 2, 2021

By -
There were a lot of clouds and there was even some rain during the whole day.  However, all weather sites predicted a clear evening.  And indeed, in the evening, the clouds parted and it became clear.  I started observing around 23:30 and I stopped at 0:50.  The temperature dropped from 2.6 (82%) to 0.7 (89%).  The SQM value was quite good for our garden and varied between 20.07 and 20.15.  My hands were really cold!

I observed using my 18" Obsession, but I had some new stuff to test this evening:
- I could use my Howie Glatter laser collimator for the first time.  It is very easy to do the collimation myself now, thanks to the TuBLUG.  
- For my birthday, I got a R-Sky Hooded Observing Vest.  The vest itself is very useful with a lot of pockets.  Very easy to put some eyepieces (and the SQM-meter) there.  The hood itself is also very nice.  It is possible to remove all the background light.  This was very relaxing and helped me to see the faintest details in the objects.

I mainly observed bright and spectacular objects.  I started with M 3.  After that, I could see the nice comet C/2020 R4 (ATLAS).  Some more detailed observations were made of M 99, M 104 and M 64.  I ended my observations with M 81, M 82, and M 13.  M 82 was really spectacular this night!

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
