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?

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

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 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 ...

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

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 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 ;-)
