Venus

With this PITA-19 I am more than limited, so I must settle with the N150/750 on the home modified and auto-guided EQ3. Using the Calcium K line, the Venus U and a simple red filter, I obtained the following pictures. The seeing was varying, with good moments and very bad periods. The best frames I obtained with the Calcium K filter, so the final color image is K as luminance over red as orange and K as cyan. The camera, as usual, was the ASI 178MM, no cooling this time.

The session spanned for more than two hours, so I had enough time to see the clouds move.
