Hi Masatsugu,

 

Thanks for your kind words. Observing Mars during perihelic apparitions is a nervous proposition for you in Japan and for us in Florida -- Typhoons and Hurricanes to worry about! I hope that you get some good observations.

I don't use Planetmaster since it won't work with the ST9 -- however, of someone knows how to make it work with my camera I would be very interested. Until two weeks ago I had to sort through about 500 red-light images and pick the best 30-50 to stack. Then I discovered that if I increase the exposures to near saturation, the noise is reduced enough that I can use single, or maybe two, frames for the red channel. The ST9XE has huge dynamic range and very low noise tat makes this possible. So now I can just save the best shots. Saves about two hours!

I just saw on the Weather Channel that the typhoon has weakened after crossing over Kyushu. I hope you will get some good seeing on Okinawa.

Best, and thanks for the great job displaying observations on the OAA web page,
