Using the WAT- 910HX/RC for timing occultations
The supply of new120N+ was stopped in 2012, and a more sensitive camera was available late 2013. This camera is the WAT-910HX (above) with 6.4x4.8mm - Type 1/2" CCD. The 910 didn't include a power supply or 1.25" nose piece so I used the AC-DC12V stabilised adapter supplied with the WAT120N+.
instrument is a 30cm F/4 Orion Optics (UK) Newtonian on EQ6, detecting
13th magnitude stars by video (0,32s) using the older WATEC 120N+
integrating camera. In comparison the WAT-910HX has roughly twice
the sensitivity of the 120N or 120N+. My camera is serial number 01106.
Half the exposure ( e.g. 0.16sec) gives the same result. A 1.28s exposure
just detects a 16.1 mag star. See my Log
of the WAT 910:

120N and 120N+ , the 910HX (or 910HX/RC) has On Screen Controls (OSC).
MINTRON Users will already be familiar with OSC. BUT there are only
two controls one needs to adjust on the 910HX (shutter and gain),
and after a few button pushes it becomes a lot simpler, even the dark.
Because the control settings are displayed on screen, you can record them.
Exposure> SHUTTER = 8/50s, Exposure>GAIN = 40dB
Most (indeed all) advanced setting should be turned
off for occultation video. The most important controls set to OFF
for Occultations are:
