You might think that the horizon is littered, but it is not.
Spring is coming, and everyone will go to nature to fry kebabs on the grills. And astronomers have their own special ManNGaL too. In fact, we have in our lab many instruments for telescopes, which were created by the hands of those who are endlessly passionate about this business. Luminous efficiency reducers SCORPIO-1, 2, which I have already described, MaNGaL is a photometer with a tunable filter for the 1-m Zeiss telescope of the SAO RAS and the 2.5-m telescope of the GAISH MSU, STOP is a photometer-polarimeter and extragalactic grandson of SCORPIO under the code name "MAGIA "For the 1-m telescope of the SAO RAS. There are still several devices that are awaiting reconstruction, and we will not talk about them yet. And how many devices live in the form of ideas cannot be counted.
The devices live in the laboratory, which is located at the Lower Scientific Site of the SAO RAS, so every observation begins with a journey. And if with SCORPIO we need to drive only 16 km up the mountain, then MaNGaL most often travels near Kislovodsk.
From CAO to KGO
In fact, I had to shoot all the frames for this article personally, but the quarantines prevented me from obtaining permission to enter the Caucasian Mountain Observatory of the Moscow State University. True, I do not lose hope, because a real astronomical utopia reigns there, when bureaucracy does not interfere (or, to a lesser extent) astronomers work on the telescope, as well as write software for it, stop it for modernization and get excellent scientific results. And there is a lot to tell about the telescope itself.

Well, if you would like to read a little more about MaNGaL, then here is a link to the publication in Experimental Astronomy magazine for the last 2020 ADS: 2020ExA .... 50..199M .
We also have a small page dedicated to MaNGaL, where you can also find more information (though only in English).
