Hello, here is Arcturus by SV Ebony eyepiece camera Capt 00001: exp.t. 31 ms, Capt 6: 125 ms, gama and gain cca 100.

Skygems found my m104 data (along with 55GB of other peoples!). I (over)stretched it using GIMP.

 

[bruha]

Hello, here is sunspots (green filter) from yesterday+highlighted by GIMP
lot of succes

[bruha]

Hello, I would like to ask ..I have problem to upload image 640 kB its reported "too big". Do you know what is size limit for attachment?

thanks and lot of succes...

 

[bruha]

And 209 kb is too big as well...

 

[bruha]

Hello, I attach two sun images from today -one sunspot appearing...
Lot of succes

 

[bruha]

Hello, I attach two moon image ( corrected by affinity photo.. I think better thean Gimp software), second is
with added artificial light source...

 

[bruha]

Next I attach three Spica images (all is made with eyepice SV Ebony webcam) while last one is with removing background (Afinity function)...

[bruha]

Hello, it is two sunspots from yesterday (Gimp corrected. ..)Although is clear sky nowadays is bad condition for observing as astronomical night is very short...

 

[bruha]

And some with green filter.. here is only one but more significant,,,

 

[bruha]

Hello, I attach sun spot images from today (on second white I got little different shape)

 

[chemisttree]

What was your shutter speed for the white? The green? What time of day do you take your images?

 

[bruha]

Hi, it was about 4 afternoon and made by SV EBONY eyepiece camera with exposure adjusted on cca 2.0 ms
and very low gain cca 2 for all images. Subsequently I made little sharpening and highlighting of spots in Gimp.

China on Mars...

By the way, I'm looking for more powerful tele lenses.
I am thinking of something like this :

A slice of the Moon

I saw a nice, small Moon yesterday evening, so I fetched my gear and took some shots before it disappeared behind the trees, using my vintage Tokina 400mm f/6.3 tele lens (set at f/8). Camera settings: ISO 1600, shutter speed 1/500 s.

The Moon before it disappeared behind the trees:

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

 

[bruha]

Hello, here is sunspot from today (original and Gimp corrected) as seen spot has structure with dark core and brighter outer area )

 

[bruha]

And some with green filter...

 

[DennisN]

(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.

 

[bruha]

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).

 

[DennisN]

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".

 

[bruha]

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... )
