Lovely :)

What lens are you using to achieve 560mm of focal length?

Hopefully next year once i come back from europe im gonna buy a telescope and hook up the 40d to that..

Have you tried that pic at 10% crop??

ah man I so have to try that! fully need to get myself a cable remote...

What camera you got?

i one for sale.. suited for 350d and ***d canon slrs.. 5 bucks..

if it doesnt work more than happy to give refund :P

reason for sale - sold the 350d ages ago and got no use for the cable!!

OMG check this out..

What's even cooler to me, is that you captured your first nebula, too - the arrow I drew in the attached image points to M42 - the great nebula in Orion.

Wow, your rush job destroys anything I've attempted with star trails. The colors are awesome and I like the composition too. Congrats on your first constellation and deep sky object. The entire sword of Orion shows up very well. No failure here, just great work.

WOW so i captured my first nebula!!!

I always loved astronomy and hopefully next year once i come back from my europe trip i will be buying my first telescope!!

you know what that means :)

40d will be hooked up to that to capture some deep astronomy nebulas, clusters etc etc..

Nice wish i had such big zoom lens!!

How do you find those extenders anyways? I wish they made one for efs lenses..

Any reason why you didn't choose the 2x extender?

With the 1.4x TC you only lose 1 stop of light. On my 400 f/5.6L with a 1.4x TC it actually becomes a 400 f/8L and auto focus is lost. If you use the same lens with a 2x TC it loses 2 stops of light so it would becomes a 400 f/11 L....

Also the 2x TC loses to much image quality as well. I hardly use my 1.4x TC..

Sorry another quick question - why did you choose just a fixed 400mm lens? You do much sports photography? Or do you have the 100-400m lens?

I wanted a long lens for a decent price, I was not keen to fork out 10k+ for the 400 f/2.8L so I chose the f/5.6L version.

Basically it comes down to this for me. The 400 prime is sharper, faster to focus, more ergonomic and does't have that crappy push/pull system the 100-400 uses. I thought about a long lens for years before I bought one. I use it a fair bit for surfing and other kinds of shots, its a good lens. Tack sharp. I have the 70-200 f/2.8L IS for shots under the 400mm length :)

Oh you got a 70-200 already.. That makes more sense now :yes: Wish i could afford it.. sigh

Thanks for the info about the extenders!!

Hopefully next year i can buy a telescope and hook up my slr to that!!

Xmetal - hmmmmm sorry but i just dont like the look of that car..

Did a quick test at 70mm with my new lens i bought today :P

I think it did just fine!! What you think?

    • Yeah I also looked at Plazmaman, but, it ended up alot  cheaper getting black ones through EFI when you also added in the delivery cost
    • Nice shot! They look super clean. The roof rack delete on the black one is interesting. Would like to see more pictures from different angles. It's subtle but could make quite a difference to how the car looks in profile.
