Davvero notevole. Ottimi contrasti. Forse un pelo decentrata (ma un crop risolverebbe facilmante).

Anch'io ho il tec 140 e stavo proprio in questi giorni pensando a un moltiplicatore da usare con la mia 5D modificata. Ho anche lo spianatore di campo e non capisco se anche tu l'hai usato in questa ripresa.

Puoi darmi qualche dettaglio sull'1.4x serie II?

Very impressive. Great contrasts. Maybe a hair decentralized (but a crop solve facilmante).

I too have the tec 140 and I was just recently thinking of a multiplier to use with my 5D changed. I also flattening the field and I do not know if you've used in this recovery.

Can you give me some details cover 1 .4 x series II?

io non lo userei moltiplicato...forse l ' 1.4x o 2x dell' FSQ sono buoni però il tec è un rifrattore a campo curvo poi corretto con spianatore quindi non so se si adattano io userei il "bambino" liscio liscio:-P

I do not ... maybe I'd use multiplied 's 1.4x or 2x of' FSQ are good but the tec is a refractor field flattener curved subsequently corrected so do not know if they fit I would use the "child" Plain Plain:-P

Grazie ragazzi, troppo buoni!

Lorenzo non ho usato nessuno spianatore, ho utilizzato il tc 1,4x interponendolo fra la eos e il naso da 2", il risultato di questa prova non mi dispiace affatto ma a f10 con la reflex è tosta tirar giù segnale, ci vorrebbe una ccd mono Sorriso
Unico dettaglio è che ho dovuto tappare i contatti del tc con del nastro, altrimenti la reflex non digeriva Confuso

Canonpo perchè tanta recalcitranza? Il tec l'ho usato anche a focale nativa senza spianatore su aps-c non si sente la mancanza, e nemmeno con il riduttore astrophhysics uso lo spianatore...a dirla tutta lo spianatore non ce l'ho proprio Sorry

Thank you guys, too good!

Lorenzo I have not used any flattener, I used tc 1.4 x interposing between the EOS and nose 2 ", the result of this test I do not mind at all but to f10 with the camera is tough to pull down signal, it would take a ccd mono :-)
Only detail is that I had to plug the contacts tc with tape, otherwise the camera is not digested: fconfuso:

Canonpo why so recalcitrance? The tech I also used a focal native without flattening of aps-c does not feel the lack, and even with the gearbox astrophhysics use the flattener flattener ... to be honest I do not have the right :-|

no mi riferivo a cobarcore ... ho uno strumento quasi perfetto e lo moltiplico con dei "vetracci".... per andare a focale 1400 Sorry io lo terrei liscio liscio..... cosi è un gioiellino... ma sono mie considerazioni...



no I was referring to cobarcore ... I have a tool almost perfect and multiply with "vetracci" .... to go to 1400 Focal :-| I'd keep smooth smooth ..... so is a little gem ... but they are my thoughts ...

Non per dissentire ma dal risultato non direi che sono vetracci...:-P

Not to disagree, but ultimately would not say vetracci ... :-P

io non li userei con un rifra da 8000 euro .... forse la mia zeiss fluorite baader a 4 lenti ma parte da 3x... ma non userei neanche quella Sorriso a uno star party ho visto uno montare un kenko 1.4 su u 130 astro-physics.... e mi sono detto echecc....o:-P:-P:-P

I would use them with a refractive index from 8000 euro .... maybe my zeiss fluorite baader 4-lens but the 3x ... but I would not use either one to one :-) I saw a star party mount a kenko 1.4 on p 130 astro-physics .... and I said echecc .... or:-P:-P:-P

Grazie Elio per i chiarimenti e Canopo per i pensieri. Sarà, ma a giudicare dai risultati di Elio non pare che il moltiplicatore funzioni male. Eeeek!!! Il leggerissimo ingrossamento stellare ai bordi estremi che si vede in questa ripresa penso sia dovuto più all'assenza di spianatore che altro.
Usando l'1.4x con la 60d non modificata potrei avere un campo dimezzato rispetto alla mia 5d, tappando quindi un "buco" temporale nella primavera, povera di soggetti grossi e rossi, e invece ricca di piccole galassie. ;-)


Elio Thanks for the clarification, and Canopus for the thoughts. Maybe, but judging by the results of Elio does not seem that the multiplier malfunctioning. wow! The light enlargement star at the far ends that you see in this shot I think it's due more to the absence of flattening anything else.
Using the 1 .4 x 60d with the unmodified I could have a field half compared to my 5d, then plugging a "hole" in the spring time, poor people big and red, and yet full of small galaxies. ;-)

Di niente Lorenzo, mi pare il minimo dopo tutto quello che ti ho carpito MrGreen
Sapessi quant'è comoda la 60d col telescopio Sorriso
Canopo ho la barlow zeiss 2/4x ma se la monto sul T2 estende a 2,6x un pò troppo per il Tec, così ho provato il tc canon 1,4x ;-)


Di Lorenzo anything, I think the least after all that I have taken away:-D
Know how much is comfortable with the 60d telescope :-)
I have the Canopus zeiss barlow 2/4x but if I climb the T2 extends to 2.6 x a little too much for the Tec, so I tried the canon tc x 1.4 ;-)

Grazie Gian, gli apprezzamenti dei meno esperti fanno piacere proprio perchè partono da un'altra prospettiva ;-)
Ciao.

Thanks Gian, the assessments of novice enjoy just because it starts from a different perspective ;-)
