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.

With the small gear, I imaged Venus. This time, the U filter delivered the best image, as a combination of the seeing and timing and the height of the planet. Modified EQ3, soapbox, N150/750, ASI 178 MM cooled, Baader Venus U, Red and Calcium K line filters were used during the session. The final picture depicted here combines the U filter as luminance, applied on top of the red as orange and u as cyan false color.

Venus

Using the experience gathered from my balcony observatory, I tried the old gear: the N150/750 on the now modified EQ3, and targeted Venus with several filters and the cooled ASI 178MM. Most pictures came out to be garbage, but some were good enough to start mixing them together. So I created a Calcium(Red-Calcium) bicolor image. Red became orange, the Calcium K line became cyan, and the Calcium K was applied once more as a luminance layer. It was kinda the first light for the ST4-enhanced EQ3 with the soapbox-guidance.
