Hi I attach my recent attempt of Saturn images (by mobile camera on eyepiece hyperion)...

good effort, I can make out the rings

I was trying this method beacouse I can not catch it by Nikon body camera attached by bayonet. If somebody has some advice and experience of Saturn photo I would appreciated it

I cannot remember what sort of telescope you have ?
let us know and also show a photo of the eyepiece end of your scope along with a photo of any adaptors you have to mount the Nikon onto the scopeDave

Hello,
thank you. I have Newton telescope diameter 110 mm x 600 mm focal distance and use with Hyperion eyepiece 8 mm. Photos are attached. Saturn images are made just by phone camera pressed on eyepiece. With Nikon body on photo I was succesfull only with moon up to know.
Thank you ….

Thank you ….

Thanks for that

Did you know there is a thing called a T-ring adaptor ? they are for connecting DSLR cameras to telescopes
There 2 parts needed, the actual T-ring and the extension tube
looking for your Nikon ……

here's a supplier close to me, but it will show you what to look for with a supplier near you
You can see they are not overly expensive

Hi And thank you for informativní.In fact I have this T ring ( asi on photos if ,you get IT) my Nikon body but without extension tube..do you think that this tube can improve taken images?
Thank you And nice day ( can i ask where you from)?

Hi And thank you for informativní.In fact I have this T ring ( asi on photos if ,you get IT) my Nikon body but without extension tube

OK so you have the T-ring ( the bit closest to the camera in that link photo)
You need that tube part that you see in front of it ... it slides into the eyepiece holder tube

In this mode, it is called Prime Focus imaging ( no eyepiece is used

do you think that this tube can improve taken images?

What it allows is for the camera to be held steady so that you can get focus easier
One of the biggest problems I have seen with your imaging so far is that they are all out of focus...
this is because the phone camera is trying to and failing to get correct focus when it is aimed at the eyepiece

Thank you And nice day

and you too ... looking forward to seeing your imaging improving as you get more experience and you get gear working well

can i ask where you from)?

You can

I'm in Sydney, Australia. I immigrated to Australia from New Zealand 18.5 years ago
It's almost impossible to do good astronomy from home ( other than Sun, Moon and planets). The sky is just too bright with light pollution.
For deep sky galaxies, nebula and star clusters etc. I often travel an hour to get to one of my darker sky sites so I can do observing or imagingcheers

I got a link from a friend today, with this awesome image:

"You’re looking at the center of our galactic home, the Milky Way, as imaged by 64 radio telescopes in the South African wilderness."

Hi and thank you for explanation, I understand- and will try to get this tube. Anyway I am from Prague, Czech republic therefore we look on absolutely opossite sky hemispere! I was on NZ 10 year ago and liked it very much -I remember that only star constalation which I recognized from Europe was Orion but upside-down (I was in Sydney as well and although it is beautiful city I think that living on NZ is more pleasant..)
So lot of succes with your imaging and when l make some improvement I ll send it..

Up at 4 am to watch the total eclipse of the moon ...
Question ... If the sky is 1/2 covered in cloud, which half will the moon ( or other astronomical event) be in ?
Answer ... the cloudy 1/2, of course

Missed the start due to the cloud. It then cleared up and saw up to 10 minutes before totality started and only tiny glimpses between then and 6 am...
Didnt see max totality at 6:20 AM ( Sydney time) ... AGAIN ... that is 5 total eclipses in a row I have now missed due to cloud

Canon 6D 100 - 400mm zoom at 400mm and with a 2 x teleconverter.

cheers
Dave

Thats great despite missing the start due to cloud. Notice that between image one and two the tone overall went from green to red/ blue? The tone did not change after that till the final image, just the size of the shadow. Then red overall in the final image.

 

[Nelli]

very nice, thanks you for posting this

 

[davenn]

There may well be a hint of green in the first image … I really have to look hard to tell …. images 2 to 5 look reasonably even

Progress to date for the region containing the North American Nebula in Cygnus: the full image is a 2 x 2 panorama taken at 400mm, the first image is a central crop, followed by some details of the nebula and the planetary nebula NGC 7048:

Each image is about 1.5 hours total integration time. I had to re-do the flat field correction a few times until I got a good enough set of flats, and getting the color balance matched between images is tricky. I honestly don't know how other people manage to make this seem easy.

 

[davenn]

awesome effort Andy

is that planetary neb. somewhere within the Nth American Neb. ?

Thanks Dave, I really enjoy looking at our wonderful creation from the tiniest life here on Earth to our vast universe. I wish NASA would hurry up and discover how to make artificial gravity and find a way to make a "warp" engine that could stand up to Einstein's theory of relativity. I know we will find a way! NASA is looking into it now, with a design to travel. Two physicists suggest that a future spaceship could fold a space-time bubble around itself to travel faster than the speed of light. This is an exciting time for our planet if only everyone in it could wake up and work together. Projects like Mars One and the other moon base designs are cool too. In college I went for a science major with focus on physics and geology. If I were only younger with what I know now... I love this site, I feel alive when I read all the stuff everyone comes up with. What a learning tool. ;-))

 

[Andy Resnick]

awesome effort Andy

is that planetary neb. somewhere within the Nth American Neb. ?

Yes-
RA: 21h14m15.2s
DEC: +46°17m17.9s

I 'discovered' it first in my image- I wondered why there was a blurry blob- and then identified it via Google Earth (Sky).

 

[Andy Resnick]

Improved background subtraction and blending:

 

[bruha]

Hi
your image are very interesting and beautiful.. Here in Czech Republik (Bohmerwald) was very cloudy so We see eclipset just in the end (and if partly visible it was of course normal (not darkened (red)) half of the moon !-- So I catch just Mars (it was good to see) and Saturn (images attached, Saturn is sharpened and little coloured in photoshop)

Lot of succes (we have terrible hot now I hope you do not as you have winter….

Something a little different- This is a 25 second exposure, just a Canon Rebel camera on a tripod. The white streak is the International Space Station, as it zips past Jupiter; I had to drive about 1.5 hours to get to the right spot to see it transit Jupiter. The stars to the left are Scorpius, and the moon is just out of the frame to the right, illuminating the clouds. The thunderstorms gave way to clear skies just in time; a beautiful evening.

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!

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..
