#evscope — Public Fediverse posts

A convenient followup: our paper on photometric calibration of the #eVscope just came out: https://doi.org/10.1117/1.JATIS.11.2.028002

Check it out 🙂

Here's an image I took of the Whirlpool galaxy in my backyard a few nights ago with an #evscope.

My backyard is not especially dark, there is a lot of #LightPollution. But the camera integrated the starlight for about an hour, and displays the background as black (with the light pollution removed).

Without light pollution, the background would still be black, but the galaxy have more details and would be more defined, because the signal to noise ratio would be much higher.

When I was born, our civilization didn't yet have evidence that other stars had planets.

Last night, I took measurements of a planet crossing the face of another star from my backyard with an #eVscope.

How cool is that?

Check out the flash from this #evscope #satellite observation. (Left is a still, right is a video - mouse over to see)

#LightPollution

Last night, Sicco Bauer and I made simultaneous observations of the GOES 12 satellite through an #eVscope. Sicco was in Dresden, I was in Bochum (~450 km apart).

We both see a dramatic brightening of the satellite as it passes through the (different) field of view.

It's maybe not surprising, because the satellite is so far away that the angular difference is <1 degree. But still, it's cool that this can be done, and shows the utility of the setup.

Turns out I can still catch #TCrB from the attic in the early evening!

A bit of #astronomy this evening via my #evscope #jupiter #horseheadnebula #flamenebula #trianglenebula #m33 #unistellar

Gonna do some #CitizenScience tonight! First counting lights with the #Nachtlichter (Night Lights) app, then taking images of the recurring nova T Coronae Borealis with an #eVscope. (Then doing my second #Nachtlichter observation later in the evening).

You can take part in #Nachtlichter, too! Check it out here: https://nachtlicht-buehne.de/nightlights

Even under less then optimal skies my #evscope still pulls it in for a better then decent capture.

That blue-green smudge is comet C/2023 E1 (ATLAS), which I photographed last night with my #Unistellar #eVscope #comet

Although in very light polluted skies, I am back to observing.

The Sombrero Galaxy

Supernova 2023ixf located in spiral galaxy, M101 (the Pinwheel Galaxy). Shot just now with my #Unistellar #eVscope #supernova

The amateur #astrophotography
#evscope telescope made by #unistellar in #Marseille, France, makes it into a Nature paper!

Some skilled amateur astronomers managed to catch the moment when NASA’s Double Asteroid Redirection Test (DART) spacecraft slammed into an asteroid on purpose last September 2022.

Tonight's nearly #fullmoon shot with a #Unistellar #eVscope

The Whirlpool Galaxy (M51) with its eye-catching spiraling structure which appears to swallow its neighbor...

Watched from downtown #marseille on a moonlight-less yet lightly cloudy night using 6 min exposure on the evScope.

December 2nd of #AstroAdvent the International Space Station #unistellar #eVscope

It is December and I am celebrating #AstroAdvent by putting out a new astronomical image every day as we count down to Christmas. All images were taken by me this year with a #Unistellar #eVscope.

A composite shot of Jupiter and the Galilean moons shot lastnight with my #unistellar #eVscope.

The star known as Gamma Trianguli (center) as caught with my #Unistellar #eVscope a few nights ago. Gamma Trianguli VI was the home of Vaal in the classic Star Trek episode The Apple.

Here's last night's view of 12th magnitude asteroids 419 Aurelia and 478 Tergeste. Each is currently about 2 astronomical units (300 million km) from Earth.The asteroids were about 7 arc minutes apart and will be even closer tonight. The image was 5-minute exposures taken with a Unistellar eVscope2. #asteroids #unistellar #eVscope #astronomy
