Celestron 14" SCT F/3.6 (f 1278mm 1.1 arc seconds/Pixel resolution) +SBIG ST-10XME free tracking (POLEMASTER 2017 0805 modified) Showa 20E revised +NS5000 for SHOWA20E (under test). +TheSky GOTO system.
Observable variable stars: CCD: 16 Visual: 01
Notice:
*. This is one of the few variable stars observed by Daxi Observatory in the second half of the night, and the viewing field in the second half of the night is close to 1.1 arc seconds, so it is similar to the state of SQM=18.87. It measures the night sky at an altitude of 6 to 800 meters, and the brightness accuracy reaches +/-0.02mag (normally +/-0.081mag).

*Orion GCVS T Ori Story
GCVS T Ori Although the classification of this variable star is relatively complex, it basically belongs to the UXO category and is also called UX Orion variable star (spectrum B8-A3 eap), and is collectively called UXor in the literature. It belongs to a subgroup of young stars, and its brightness at the time of observation shows irregular changes over a wide range of amplitudes. In older data, the brightness change is more stable, about 8.95-9.01 magnitude (V band), but in recent observations, its brightness has decreased to 11.4 magnitude (V band 2024 0217 Daxi Observatory observation) Because of the decline, AAVSO recently adjusted the brightness range to 9.5 to 12.6 magnitude (V band).
