(139) Juewa occults TYC 0003-00687-1 for 12.08 sec +/- 0.02 sec

Back to Positives

Observed with a 14" LX-200 ACF using F/3.3 focal reducer and a WAT-910HX video camera running at standard PAL frame rate (using no integration) with Gamma of 1.000 and Gain of 41 dB. The video was recorded unattended using OccuRec. This was my second positive event recorded using the new AAV format as well as my second ever occultation recorded unattended. I forgot to turn on the dew heater of the scope and the corrector plate was completely fogged but the light from the bright 10.2 mag star was still getting through.
