Hello!
I hope this finds all well.

A new (and final) Czech record has been set!

Since it is impossible to see all the objects from the 50N latitude, I decided 
to go a bit south this year. I took an air trip to the Portuguese island of 
Madeira, located at 32.7 degrees north latitude. I ran three marathons there 
from March 17 to 20. The first using only 12×50 binoculars, the other two 
using a portable 10" f/4 dobsonian telescope.

The first night on the west coast I missed only two objects: 
M74 in the evening due to the strong zodiacal light and M30 in the morning. 
The next night I went up into the mountains to an altitude of 1800 metres 
above sea level. From there, I was able to easily log all 110 objects, only 
M30 in the morning was very difficult. 
After this experience, during the last night I repeated the result of the 
previous run from the seashore with greater ease. The first 48 objects took 
me only 10 minutes, then I observed a few more at 2am and finally the rest 
except M30 within 15 minutes before dawn. I had to wait another 30 minutes for 
the M30. All observations were made from memory.

I wrote a report in Czech:

Take care!
