Apart from the air, it seems to me that the spizzicato a comet :-)
I have always been unlucky. :-(
It seems to me a bit noisy, you may lower the ISO to 1600 and if you're hunting for comets also try 800 and take the time to 30 sec.
The Dark did you do that?
I like the shot.
Hello

Hello Alberto ... thanks for the comment.

What is the dark?
Hello

Esattoooo,
the top right is a comet.
The Dark is a shot with the cap over the lens, with the same setting of the other shots, I'll explain:
These are the data of your shots, 20 sec f/5.0, ISO 2000, well you put a cap over the lens, set the machine to 20 sec f/5.0, ISO 2000 and shots, then start the sequence as expected,
should make more than one dark, I get one at the beginning and one at the end of the session, with the sensor warm.
in post plus the dark or dark to photos that are subtracted, removing much of the noise.
How it works? :-)
here comes the fun, or use photoshop, and it is long and laborious, :-|
or all use a very simple little program that results from meGliori, it's free and very intuitive,
maybe that's what you use, but rule it out, then continued.
I've downloaded the program here:
markus-enzweiler.de/StarStaX/StarStaX.html # download

:-P

* Go down to the bottom of Download and Installation
* Circles under Mac OS X version (stable) or Windows version (stable)
* Click "on StarTaX - 0.41"
* Prepares himself all alone, the program is in English, but very intuitive.
Go and let me know ;-)
Ciaooo

Sorry if I introduce myself on the boards ... try to see whether the D5100 has the Noise Reduction function (Nr Job) ... simulates a dark frame! :-)

thanks Alberto & Paul ... I do not use that program I am using a downloaded always from germany which of course is called Startrail.exe, and they also have the opportunity to enter the darkframe ... which in practice would be a completely black picture right ? :-)
In my nikon is possible to activate the noise reduction on high iso high-normal-to-moderate cmq when I make Startrail shooting only jpeg end so the memory buffer fills up every 100 continuous shots in raw and I think there are very few .
hello
Alessandro

Paul,
I'm finding I also try to do this type of shooting and, as I understand it, I think the noise reduction in the room should be rejected.
The reason is that the noise reduction needs the same time of the shot, 30 seconds of work 30 seconds per photo. in this way would contrail with interruptions very long. Much better than the dark frame, the more that is processed only once and automatically.

Alexander,
I did not understand the reasoning about shooting in jpg to avoid filling the buffer memory. : Fconfuso:
Taking long shots, 10 20 or 30 seconds, there is no danger of filling the buffer either in raw as the car has plenty of time to copy the memory card each photo.

I tried the star trails with a nikon d5000, which is lower than yours, and I can assure you that I have not had any problems,
not to exceed ISO 1600 with those machines go and see better.
A word of advice, for all I know, star trails does not handle 16-bit StarTax is a bit 'more evolved and that's fine.
Health at all, you go on holiday

Alberto Happy Holidays!

Daysleeper ... the first time I've done one Startrail, fotogradando with continuous shooting with telecomandino on hold was interrupted after 100 shot, I thought it was the battery but it was still full wow!, Then saw that he made 100 shots are precise went to see the manual and there was just the voice of buffer memory sd, cmq after the hundredth shot if you start the operation, the machine starts to shoot,
at least from what I understood my nikon D5100 works well ... maybe it's me that I need to change something :-)

Ah, now I understand!
I assumed an intervalometer not think you could do tot photos with continuous shooting and cable stuck in hold ... :-P

In the case of an intervalometer the problem does not arise, since they are to all effects independent pictures.
However it seems strange that the machine does not start to clear the buffer while capturing more photos, I would have all the possibilities, but maybe they blocked it as a matter of readiness in the shot.

Yes, I know one since I got it. ;-)
I do not know if you can put a link to ebay on the forum so I am sending you a private message.
As soon as I can control what I got exactly what I stated, but I'm 99% sure.
