FELICITARI !! Noi, cei trecuti de varsta a treia privim uimiti la ce fac tinerii de astazi.
Indicativele noastre se reflecta de ionosfera. Dar niciodata n-au plecat din stratosfera ca in acest caz. Aceasta imagine va sta in memoria aprs.fi doi ani. In acesti doi ani vor mai ajunge si altii pe acolo ?
Mai mult ca sigur. Tinerii nu se lasa . Si este o dovada a libertatii in care traim . Felicitari ! 73s !

De pe pagina amicilor de la Vanguard Technology

On our flight from 18 Jan 2020 (VGT3) we had an experiment with a high level of complexity: an attempt to achieve balloon astronomy by taking photos of the Moon though a medium-long focal lens and a mirrorless camera from the nacelle. The Wikipedia page for "balloon-borne telescopes" keeps track of various similar experiments some dating back to 1957 - project Skyhook. To our knowledge, it's the first time such an experiment was attempted in Romania.
To achieve this target a simplified reaction wheel stabilization system was implemented + a camera tilt control depending on the time and moon altitude. The focus was performed manually on the ground by using a distant tree, take into account o that day it was fog and cloudy.
The camera used was Z CAM E1 and the lense we set to 103mm focal length
The maximum altitude from where we got a decent picture was 18.3Km
Pictures are copied directly from the camera: no processing was done
Work was done by Iaroslav-Andrei Hapenciuc YO3HCM
