Venus, false color

So I imaged Venus and deployed the technique describen earlier: the Calcium K-line got cyan, the visible light’s RGB got orange, and the false color outcome is featured here. Because I noticed that the ASI 178 tends to run at ambient plus 10-15 degrees Celsius, I made it a cooler, quite similar to the one on the ASI 224 MC, and reached ambient t – 5 degrees and maybe way less noise. Though imaging Venus like this, from a hole in a wall, on the daytime sky with two instruments may sound easy, or I may make it sound easy, it wasn’t. It was almost as hard as doing it for the first time.

The 178 also got a peltier
