Our Beautiful Universe - Photos and Videos

[Andy Resnick]

Just got back from vacation at the beach- I have about 1 TB of images to sort/stack/stitch which should keep me busy for several months... kinda like data analysis after an accelerator run :)

Here's a few 'quick looks', taken with a 105/1.4 lens, wide open. 1.3s exposures, ISO 8000, about 30s total exposure time. Unfortunately, downscaling to 800x600 really wrecks these, but I'm happy to report that the lens is pure magic- near perfect. I'm having a lot of fun with that lens, for sure. The first 3 images are Lyra, Andromeda, and a section of the milky way:

I'm really hopeful that the milky way panorama will result in a 'print-worthy' image. Here's a less-downscaled but still not 1:1 closeup of the lagoon and trifid nebula with saturn- you may be able to tell that images from multiple days were combined, as saturn is in two locations:

The next image was taken with a 15/2.8 lens during the Perseid meteor shower- new moon, so the sky was super-dark (30s ISO 4000). There is a meteor visible in the image, but again, downscaling obliviates it. This image is part of a timelapse, which I've already uploaded to my Youtube channel.

I like all of them, but particularly the first one!

Part of the Veil Nebula (1:1 crop):

105/2, 30s ISO 200, about a dozen frames. Trivial!

Breathtaking Andy, beautiful.

First attempt at a stitched panorama of Cygnus:

The original is about 8000 x 6000 pixels, and the average star FWHM is 3.1 pixels (about 10.5 microns).

 

[Andy Resnick]

Here's a first attempt at stitching together images of the Milky Way; about 35 stacks of images (total integration time per stack is about 1 minute = 50 images):

This is about 0.1% of the size of the original (20k x 20k pixels). The bright spot in the center is Saturn, and the field of view spans NGC 6124 at the bottom right to M11 (Wild Duck Cluster) in the upper left.

A nice view in the western evening sky a couple of nights ago

Lower left is Venus, lower right, the Moon and near the upper edge, Jupiter

Hi I attached few images I made on Kefalonia last week.
moon just by camera
2 x moon by telescope
2 x Saturn by telescope (it is just attempt but I have problem inpossibility to adjust manually time exposition -so it is about 1/4 sec and therefore fuzzy...)
Hi and have nice days..

 

[Andy Resnick]

Ok, some results of imaging Cygnus @105mm and 400mm: Getting closer to being print-worthy...

 

[bruha]

Hello, your milky way is very impressive, (and cygnus as well).. which software do you use?-I have Registax.but not experienced ...( I send as sample attempt of Moon image sharpening)

Hi and lot of success!

Hi and lot of success!

Thanks! I use Deep Sky Stacker for stacking, Fiji/ImageJ for most post processing, and if needed, Neat Image for noise reduction and Hugin for stitching.

 

[bruha]

Hi thank you very much for information and lot of sucess, I will try and send some sample if sucess:)

hi,

Don't use Registax for deep space stuff ... only use it for solar, lunar and planetary stuff

For deep space image stacking, Deep Sky Stacker as Andy and I use is a great easy stacking program, then do editing of the stack in Photoshop etc

There are other programs that cost money, some lots of money and are much more complex to get to understand
eg, Nebulosity3

 

[bruha]

Hi thank you for advise- yes It its true- I would like to get deeper space but with my condition (I am from Prague) I have no much chance..(do you think that for example andromeda galaxy is relatively easy to take ?

Hi thank you for advise- yes It its true- I would like to get deeper space but with my condition (I am from Prague) I have no much chance..(do you think that for example andromeda galaxy is relatively easy to take ?

I am located in an "suburban/urban" location, my night sky is horribly light-polluted (in addition to generally poor seeing conditions), so I would argue you have very good chances.

 

[bruha]

Hello,
I attach two images processed by Registax (two settings of filtering) and original image as well.
If you have somebody some experiences with Registax I appreciated some advice…
Have nice days and lot of succes..

High resolution from the International Space Station:

Experience High-Res Science in First 8K Footage from Space

Fans of science in space now can experience fast-moving footage in even higher definition as NASA and ESA (European Space Agency) deliver the first 8K ultra high definition (UHD) video of astronauts living, working and conducting research from the International Space Station. The same engineers who sent high-definition (HD) cameras, 3D cameras, and a camera capable of recording 4K footage to the space station now have delivered a new camera capable of recording images with four times the resolution than previously offered.

Hi, I attach images of Rigel and Betelgeuse (it was take by 1/4 sec. exp. time so it is fuzzy but different colour (temperature)is recognizable..
have nice days

Some of the stuff I've seen on here is unreal.
This is one of those. Hats off to the scientific community and engineering guys on this.

 

[bruha]

Hi this is my "colour playing" -four stars "images" last night...
You mean that this Mars panorama is "artificially corrected" ?
Have nice days-and nights

 

[Stavros Kiri]

After somewhat reviewing this thread, I figured something is missing. The following non-media was not uploaded in the forum:It was intented to show complete vacuum, but, since there was nothing to see, I figured I might as well skip it ...

Went out last nite, 7th Dec, for the first serious observing/imaging session for a long time.

Was very disappointed, when I got to site after a long drive, that I discovered that I had grabbed the wrong scope mount drive controller.
The controllers are the same except one has a 8 pin RJ connector and the other has a 6 pin RJ connector
The scope mount I took has the 6 pin and the controller I took has the 8 pin

As a result I had no tracking ability for my imaging
I had to keep exposures short but at the focal lengths being used, there is still some trailing.

Did some serious pushing of ISO settings to compensate a bit for the short exposures

Comet 46P/Wirtanen ... a comet with a large coma ( gas/dust halo) the size of a full moon, but the overall surface brightness is
reasonably low
10sec @ f2.8, ISO 6400, 200mm focal length ( 70 - 200mm zoom) on a Canon 6D

Large Magellanic Cloud

5sec @ f2.8, ISO 25600, 200mm focal length ( 70 - 200mm zoom) on a Canon 6D

cheers

Path of Comet 46P/Wirtanen for the first half of December 2018

I hope to get out again, weather permitting, on the weekend of the 14 to 16th Dec when the comet will be beside the Pleiades (M45) cluster. It will make a nice image

this image is flipped horizontal and vertical for us southern hemisphere observers
attached is a pdf file for the northern hemisphere observers

I've never been to Australia, but I think I understand what you mean...

'

haha brilliant

yeah ... it's nick name is the "Red Centre" ... we periodically have it visit the east coast by way of dust storms
Last time was a couple of weeks agoDave

 

[davenn]

Comet 46P/Wirtanen

well, battling mosquitoes, a bright moon nearby, bright city lights making the sky glow. I managed to get the comet near the Pleiades.--
Ohhh and when I took the scope and gear out, the sky was cloudless. Within 10 mins of doing the alignment and ready to go, the clouds started rolling through ... shot through the gaps
30 sec exposure, 150mm, f5, 1000ISO, Canon 6D
Not exactly brilliant, but better than not at all

yup, that small fuzzy green blob approx. right of centre

Astrophotography from suburbia is somewhat difficultDave

I cannot find the blob Dave, looked hard on a calibrated screen and still can't find it. There are three stars in line in the centre a lone star left of that and then a blob left of that of that, is that it?

 

[Andy Resnick]

Last night was a Christmas Miracle: the night sky was clear for the first time in about 2 months, and the last night before the moon got too close to comet 46P/Wirtanen: here's a 1:1 crop of a single frame (8", 400/2.8, ISO 800). The bright star is (I believe) φ Tau.

Unfortunately, doing 'comet stacking' with DSS is rather time-consuming, not sure when I'll finish the post processing (about 200 frames)... stay tuned.

tis a little difficult ... the forum software plays havoc with images, it lowers the quality quite a bit
