The interest to test the Vaonis Stellina by capturing the Orion nebula was huge, given the fact that M42 is just stunning to look at in my C8. The sky chart shows M42 with the approximate sky extent covered by Stellina’s sensor, overlaid.

Image taken on January 17, 2021, end of exposure ca. 21:28 CET,  Az. 172°54′, Alt. 31°53′. Vaonis Stellina, internally processed JPEG, 14 images, total exposure time 140 seconds, device temperature 7.3°C, 44% relative humidity. Green space, Berlin, Bortle class 7-8,  street lamps of a main road in the direction of observation, 16% moon phase.

Automatic image processing by Stellina (left) and a rather quick (moreso, admittedly improvable) manual processing attempt (right), i.e., stacking of the raw images (FITS) exported by Stellina, and further editing of the stacked image. 

Image taken on January 22, 2021, 20:10 CET,  Az. 156°11’31”, Alt. 29°28’39”. Vaonis Stellina, internally processed JPEG, 49 images, total exposure time 490 seconds, device temperature 6.2°C, 63% relative humidity. Green space, Berlin, Bortle class 7-8,  a single street lamp in the direction of observation, 60% moon phase.  

Image taken on February 14, 2021, ca. 18:30 CET (Az. 152°45′, Alt. 28°31′) to 19:30 CET (Az. 170°34′, Alt. 31°19′). Vaonis Stellina, a total of 210 FITS images manually stacked and processed, total exposure time 2100 seconds/35 minutes, device temperature from ca. 6°C to ca. -1,5°C (multiple autofocussing carried out during the duration of exposure), relative humidity from ca. 30% to ca. 53%. Green space, Berlin, Bortle-class 7-8,  multiple street lamps in the direction of observation, 8.6% moon phase.
