Qualche dettaglio in più sull'attrezzatura? Mi affascinano queste immagini ma, sono completamente a digiuno d'astrofotografia! Triste Quindi hai usato un teleobiettivo (Leica Telyt 180 f3,4) su una canon 40d modificata?

Some more details on the equipment? I am fascinated by these images, but are completely fasting for astrophotography! :-( So you used a telephoto lens (Leica TELYT 180 f3, 4) on a canon 40d changed?

Grazie a tutti! Non mi aspettavo di finire in Editor's Pick:-P

La foto è stata realizzata da Forca Canapine (Parco dei Monti Sibillini). Gli astrofili del centro Italia, si ritrovano in quei luoghi nei periodi di luna nuova per l'ottima qualità del cielo.

L'oggetto fotografato, rimane molto basso dalle nostre latitudini e per questo un po' difficile da fotografare.

La Canon 40d - da me usata- è modificata (prodotta dalla Koreana Central Ds) . Raffreddata tramite cella di peltier,con un delta di -20 rispetto alla temperatura esterna. Viene tolto anche il filtro originale e sostituito da uno che lascia passare le lunghezze d'onda tipiche delle nebulose ad emissione.


In Astrofotografia si fanno tante pose, da 5/10 minuti (o anche più ), perché allungare il tempo di esposizione stabilizza il rumore ed incrementa il segnale. Per fare ciò -ovviamente - serve una montatura che compensa la rotazione terrestre e che 'insegue' il soggetto fotografato.

Personalmente faccio 30/35 pose da 8 o 10 minuti, a cui aggiungo 7 darkframe . Il tutto viene poi mediato o sommato tramite software ed il risultato finale elaborato con ps.

Ad esempio, per semplificare il discorso, se faccio 36 pose da 10 minuti e le medio è come se avessi tenuto aperto l'otturatore per 360 minuti.

Oltre al telescopio utilizzo con enorme soddisfazione anche l'ottimo Leica Telyt Apo 180 f3,4 (grazie al pioniere Valerio74).

Spero di essere stato chiaro e vi ringrazio ancora per i commenti!

Thank you all! I did not expect to end up in Editor's Pick:-P

The photo was taken from Forca Canapine (Park of Monti Sibillini). Amateur astronomers in central Italy, can be found in those places during the new moon for the excellent quality of the sky.

The object being photographed, remains very low from our latitudes, and for this a bit 'difficult to photograph.

The Canon 40D - I have used is amended-(produced by Koreana Central Ds). Cooled by Peltier cell, with a delta of -20 with respect to the outside temperature. Also the original filter is removed and replaced by one that passes the wavelengths typical of the emission nebulae.


In Astrophotography you make a lot of poses, from 5/10 minutes (or evenmore), because lengthen the exposure time stabilizes the noise and increases the signal. To do this-of course - is a frame that makes up the Earth's rotation and that 'chasing' the subject being photographed.

I try to do 30/35 put 8 or 10 minutes, to which I add 7 darkframe. This is then added or mediated by software and the end result produced with ps.

For example, to simplify the discussion, if I 36 exposures of 10 minutes and the medium is as if I held the shutter open for 360 minutes.

In addition to the telescope used with great satisfaction also the excellent Leica Apo TELYT 180 f3, 4 (thanks to pioneer Valerio74).

I hope I was clear and I thank you for the comments!

Molto molto molto bella.
Come già scritto da altri è una delle migliori fatte dalle nostre latitudini: Ofiuco e Scorpione non si alzano molto dall'orizzonte da noi!
Ale

Very very very nice.
As written by others is one of the best made by our latitudes: Ophiuchus and Scorpio do not get up from the horizon far from us!
