Already for a few days a high pressure area settled around Belgium, unfortunately with a temperature inversion. In practice that means fog & mist in the lower parts of the country, and only the higher area’s such as the Ardennes hilltops and the “Hautes Fagnes” plateau stick out of the clouds and have sunshine and blue skies.
On Saturday we finally got some blue sky, with the C14 just in time back in business (see previous post).
On Venus, as usual – very little to no detail visible. Probably best to use an UV filter for getting some cloud structure visible.
Jupiter was captured simultaneously by the C14 (Baader IR RGB & ASI290 mono) and the Maksutov ( Player One Neptune).

With the Maksutov, the images were visibly less detailed:
Just as I was pointing the C14 towards Mars, the dew point was reached. In a few moments the whole sky completely closed like a curtain.
