Thank you all!
Besides the 500D, the instrumentation used is the following:
- Telescope Skywatcher 80ED on frame NEQ6.
- Chamber of driving QHY5L mono-II, software driving PHDGuiding II
- Processing done with IRIS, Adobe Photoshop CS6 and Maxim DL
I hope that I have not forgotten anything ;-)

It is not to nitpick (but eventually -D), but the sides seems to notice a bit of stretch stellar. You used to case one field flattener?

Quiet MarsCr, hair in the egg helps to make ever better: -D
I'm glad you found this and not the other 6/7 that I found I :-P
I tried in every way, mainly with a polar alignment meticulously executed, but in all the pictures with the 80ED, from one side or the other to me the stars are always a bit 'stretched. Many times the lack croppando delete the image, but sometimes, as in this case, I did not do (well, I did it but I think the result is better than that). The reducer / flattener dedicated to the 80ED I tried it once on the Rosette Nebula, but the result was the same, stars always stretched to the edges. I came to the conclusion that the fault lies in the relationship between the field is not properly cleared and the dimension of the canvassion sensor 500D.

But the sensor aps-c of the 500d not think already affected by this defect, if you tell me that with the flattener the result is the same ... It is not by chance that the optical suffering from a coma?

We say that with the flattener / reducer get a wider field, but at the same time the defect is amplified slightly: fconfuso:
Unfortunately, reading hundreds and hundreds of posts on forums dedicated, we noticed that the levellers in general are difficult to manage, for what it is advisable to focus on perspective already perfectly leveled. The 80ED is a good compromise between quality and price, the more one can not ask: -D
Before you start taking pictures I am made several bones on view (with alt-azimuth mount manual) and even now when perhaps I have little time to mount the whole setup photo I like to do some 'observation, but to date I have not found coma, lack a little 'more properly typical of paintings Newtons.
