, Posa B f/4.0, ISO 1600, tripod. Otranto, Italy.

Altair è una stella bianca di sequenza principale avente magnitudine 0,77, che si trova a una distanza di circa 17 anni luce dalla Terra, nella costellazione dell'Aquila. È la stella più luminosa della costellazione nonché la dodicesima stella più brillante del cielo notturno; è inoltre una delle più vicine alla Terra. È anche uno dei vertici del Triangolo Estivo, essendo gli altri due Vega e Deneb. La sua vicinanza all'equatore celeste la rende osservabile da tutte le regioni popolate della Terra. La sequenza è stata realizzata con la Tecnica di fusione Media Entropica utilizzando piu scatti a 100mm a diversi ISO. 15 pose da 2 minuti su inseguitore Star Adventurer. Realizzata in DSS, Photoshop CC con l'ausilio del nostro Panel Orionh :)

Thank you all for the comments :-D in this photo I used the sig no 70-200 not os hsm lent by my af / 4 friend :) I noticed that with this resonance technique at different iso the dynamic range exponentially increases And post-production work decreases ... If you can suggest a good goal that will open at 300mm. I had thought about sigma 120-300mm 8-)

Good angel, you know how I think it ... for me you only have that option that we discussed ....
For this high resolution image, I know this is not the ultimate goal for astrophysics, it has disrupted the stars in concert with some action used to remove some noise produced by the sensor, what you could do to try to diminish a little ' Stellar "elongation" effect, diaphragming at 5,6 or even 7,00 by removing the geometric imperfection typical of objectives too open as the one used.
It is clear that these are suggestions made by the personal experience made available to improve the final results ;-) ;-)
