Our Beautiful Universe - Photos and Videos

And some with green filter...

(I plan moon images too but unfortunately getting quite low horizont already after sunset...)

Yes, horizontally it was pretty low. But I couldn't resist it.

Hi, here is next sunspots from today -it looks as original spost gets little brother.. (on first white image)

Hi, this is just for ... Sunset from highest Andros island (Greece) point (994m).

I saw two interesting videos about black holes recently:

How To See A Black Hole
- A documentary about the Event Horizon Telescope project team which gave us the first image of a black hole. It was very fascinating to see the incredible planning that had to be done to synchronize all the telescopes all over the world, including waiting for good weather.

The Warped Side of the Universe: Kip Thorne at Cardiff University
Professor Kip Thorne is a theoretical physicist and Nobel laureate. In this talk he discusses "My Romance with the Warped Side of the Universe: from Black Holes and Wormholes to Time Travel and Gravitational Waves".

Hello, I send today sunspots white and green-it seems groowing comparing my last shots.

Another giant photo of the Milky Way...

"Accomplished astrophotographer Bartosz Wojczyński has created a gigantic 2.2 gigapixel photo of the Milky Way that he was able to capture in just one night, which is an astounding achievement given that a similar 1.7 gigapixel photo took another photographer 12 years to complete. "

The article also contains photos of the two telescopes used dually.

Article: Massive 2.2 Gigapixel Photo of the Milky Way Was Taken in Just 4.5 Hours (PetaPixel)

A zoomable version of the photo is here.

Amazing photos! When I saw the second photo I immediately recognized the castle since I've been there.
It's Château de Chambord which is a beautiful, majestic castle.

Regarding photographing the Milky Way I have not yet tried doing this myself due to city/region light pollution. But I have planned to take a short trip this summer or autumn to a quite nearby place (a beach by the ocean) which is classed as Bortle 2 (typical truly dark site), so hopefully I will get some nice shots then. And maybe I'll try to do a timelapse. We'll see.

I think that at least half of those have been on NASA's APOD.

Light Pollution Map

@davenn , @Andy Resnick , @collinsmark , @bruha, @chemisttree , @Drakkith , @Devin-M and others doing observations/astrophotography:

I don't think I've shared this link here for some reason.
It's an interactive worldwide map showing light pollution which can help to locate nearby good spots for nighttime observation/astrophotography.

Light Pollution Map: http://www.lightpollutionmap.info

Some of you may already know about the map, but I wanted to share it, since I recently used the map to locate a Bortle 3 site (quite nearby) and also a Bortle 2 site (on the small Danish island Bornholm, which is pretty close to me, and available via ferry from Sweden).

Edit: The map is scrollable, zoomable and clickable. If you click with the left mouse button on a location you get coordinates, altitude, brightness info and Bortle class.

hey mate,

I have used another one for a number of years
http://darksitefinder.com/maps/world.html#4/-18.52/-211.90

it looks very similar in it's layout, but the huge advantage is that it continuously scrolls and doesn't stop at the dateline just
east of NZ

Hello, it is my next sun image attempt by SV EBONY eyepiece camera with green filter..unfortunately I am not able with software (SharpCap 3.1) zoom for whole sun body...

Have beautiful nights ...

 

[bruha]

Hello, today I again noticed one sunspot..( but as I look on images now, I am not sure about different spot positions reason... )

 

[bruha]

Hello, this one is probably better (cor. by Affinity photo instead Gimp... )

 

[bruha]

Hello, I attach some night images from little outside Prague by SV EBONY eyepiece camera:
Deneb, Jupiter,higher exp. Jupiter with some moons and Saturn .I was trying as well Nort America nebula near Deneb but no succes (although Deneb was quite bright and I think this Nebula with 4 ap. magnitude should be imaginable...)

 

[bruha]

Still one image from N.A.nebula supposed area...

 

[bruha]

Hello,
last days I was trying first JUp/Sat. images with new scope (Newton 1000 x 200 mm) and SV Ebony eyepiece Camera while I use: BF-blue filter SV Ebony UHC, Y, Y2-light-dark yellow filter, event. without+JUp. overexp. with moons.
Lot of succes

Flying on Mars (with sound in the second video).

First Video of NASA’s Ingenuity Mars Helicopter in Flight, Includes Takeoff and Landing (NASA JPL)
In this video captured by NASA’s Perseverance rover, the agency's Ingenuity Mars Helicopter took the first powered, controlled flight on another planet on April 19, 2021.
NASA’s Perseverance Rover Hears Ingenuity Mars Helicopter in Flight (NASA JPL)
On April 30, 2021, NASA’s Perseverance rover made history as the first spacecraft to record sounds from another spacecraft on another planet. During Ingenuity’s fourth flight, a microphone included with the SuperCam instrument aboard Perseverance captured the humming sound of the blades and the din of wind.

[bruha]

:) Genéve, I suppose

The argument for switching off lights at night

Yeah but with the right filter...

[bruha]

Hello, it is beautiful image :) , recently I was trying as well to capture N.A. Nebulae (with SV Ebony eyepiece camera ) but with no succes. I attach my image evaluated by Astrometry.net- it resulting that I was really misplaced .-somewhere near Sadir.. ha ha

 

[bruha]

Hello, I still attach combined (overexp with moons+standard) Jupiter image.
