Milton, 

You`ve made that somewhat clearer & more precise now. For those 140 (is it) 2 minute exposures you`re taking of Eros do you use the Peltier cooler or does the heat dissipate sufficiently between exposures. Does each exposure begin directly the last is completed? I guess Eros isn`t visible from my location or the time frame has changed as it`s not on my ST3 list at present.

Hi folks;

The weather here sucks (smoke from forest fires, winds to 90 kmph and dust storms), so I decide to reprocess the Eros light curve data and generate a better version of the .mp4 movie.

The version 2 light curve :

used five constant stars instead of one constant star. If you compare it to the original curve you can easily see how much the check star has been leveled out, with < +/- 0.04 magnitudes now. The curve for Eros has changed quite a bit.

I also updated the .mp4 movie :

by adding a UTC time numbers, labelled Eros and some reference stars.

TTYL..
