What can I say except that the lira, as well as "elusive", is one of the most beautiful nebulae observed at the amateur level, although evolved. Beautiful photography, I would say great, at least for me.
Really compliments for the expertise and presumed "patience," nell'immortalarla. Good light - G.Piero

Thank you. In fact, to describe the equipment and technique used, it took many, many lines. The approach of course has nothing to do with photography common ... I did not want to bore anyone! But if I became aware of a certain interest, it posterei and maybe more than one, if you like, I dilungherei in the explanation of what I had to do to get it.

Beautiful.
I also am fond of astrophotography, I tried to photograph it, but without a telescope
guide, I had to take a very short time and have never been able to pull out the colors.
My ring nebula siu stop on the color blue.
When I have time even place my version.
Is estimated that a few months ago that I have tried in astronomical photography, so my version
compared to yours will be poor.
To me if you post the shooting data would be delighted!
Bravo again.
hello to you soon

certain that we are interested in all the details of 'recovery', we are here to learn from those who know more:-D:-D
Sooner or later I'll throw in this vein I also astronomical: it is really fascinating.

A large request, I'm happy to describe here the embodiment photo Astro.
Equipment location: Schmidt-Cassegrain Celestron C8, diameter 200 mm, Focal Length 2000mm F10.
E 'an instrument reflector, which works with a system of mirrors, such as to be able to contain in reduced size, of only 45 cm., Focal also of 2000mm as in this case.
E 'was also necessary to work with a small telescope driving parallel to the beam photographed.
Tool Guide: Semi Apo Carbon fiber D70mm 420 Focal F6.
The Tele driving is connected to a CCD which helps me nell'autoguida automatic, with appropriate guidance software.
Autoguiding: Starlight Xpress Lodestar
Software Guide: PHD Guide

The tools are mounted on amotorized frame that mimics the motion of the Earth, once stationed at and dot with the necessary precision.

CCD location: Moravian G2 1600, Kodak KAF-1603ME Sensor Resolution 15,361,024
This is the real camera, which performs the recovery. E 'cooled by a Peltier cell double stage at -20 ° C, to eliminate electronic noise present at the long exposures.

Software Acquisition and elaboration imaggini: Maxim DL
Software finishing PS CS5

We come to the actual shooting.
Were performed several times, each in a different wavelength:
# 2 taken from 300 sec in IR or a filter that cuts only the infrared.
# 2 taken from 300 sec in Halfa, a filter which only passes the radiation Hydrogen ionized Alfa, a particular level of atomic excitation of 'H, present in the space in objects like this.
# 2 taken from 300 sec in R or in the Red
# 2 taken from 300 sec in G or in the Green
# 2 taken from 300 sec in B or in Blue
# 2 shot from 300 sec Dark Frame to eliminate the so-called noise component of dark type, ie of darkness.

That's it!

So if you point and click with my mighty 300 mm. not a chip out of nothing, seem to understand. :-| Of disarming beauty, at least to my ignorance about! ;-)

It 'a very small object, I'm sorry to the 300 mm, although noble goal, it allows you to enlarge it enough.
On the other hand, with the 300 mm could take a picture of the entire constellation Lyra. But you should expose for at least 3 to 5 minutes, so this forces you to automate the whole ... otherwise the Earth moving, it will make the stars stripes instead point.
