This is a 40 minutes exposure with Baader 7 nm  H-alpha filter and SBIG STL11000M-C2. Weather was poor with high clouds and mist. I had to stop imaging when heavy clouds arrived. I will continue to pursue more Ha and RGB data when weather allows.

Due to some mystical issues on controlling the dome and SBIG cameras, I have decided to  reinstall  the operating system of my observatory computer. This operation will take the Cloud Sensor off-line, so there will be no cloud sensor graphic updates for a while.

I made a combination of Comet 17P/Holmes from three different nights. You can see the movement and the comet getting bigger. I hope I can continue tomorrow with a new picture.
