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??

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!!

      RB25DET with solid lifters - which cams ?

      By TurboTapin · Posted

      They are under bucket shims. Tomei provides a test shim kit and then any measurement of shim required.

      RB25DET with solid lifters - which cams ?

      By GTSBoy · Posted

      I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.

      RB25DET with solid lifters - which cams ?

      By TurboTapin · Posted

      I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something?

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states that I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!?
