Moon - 20.1.2016 at 19.00 Espoo Observation number 47930

Visibility III / V

Tommi Ropponen, Ursa (Etelä-Suomi)

First light for ASI178MM camera in Leppävaara, Espoo, about 500 m from Ring Road I. Seeing was quite fluttering and the Scene brings its own spices when in a 20 degree frost the houses have quite a lot of heat flowing and the atmosphere is anything but stable. At the time of filming, there was also a thin upper cloud in the sky messing things up. However, the IR-pass filter helped pretty well.

The image is stacked with the top 3 percent of 5,487 frames and processed with Photoshop and lightroom. Uncut image. This new ASI178MM seems to prove to be a pretty good tool.

Edit: I was still trying to drizzle the image and the second image is 1.5x drizzle output. So a single screen is starting to have a size of 3000 x 3000 pixels.

Onko Cooled-Asi? Hienon kuukuvan olet kyllä saanut.

Tämä on jäähdyttämätön versio. Tosin näillä keleillä kuvaussession lopussakin kennon lämpötila oli vain 0.9 astetta.
