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..

I just got my results back from that picture of ORION..

This is what i captured

Hello, this is the blind astrometry solver. Your results are:

Orientation:52.47 deg E of N

Pixel scale:288.60 arcsec/pixel

Parity:Reverse ("Left-handed")

Field size :64.13 x 42.73 degrees

Your field contains:

The star Sirius (αCMa)

The star Rigel (βOri)

The star Alnitak (ζOri)

The star Saiph (κOri)

IC 2118 / Witch Head nebula

NGC 1976 / Great Nebula in Orion / M 42

IC 434 / Horsehead nebula

IC 2177

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?

    • I had absolutely no symptoms whatsoever that anything was wrong.... I'm very happy it was all spotto'd and re-bled and re-torqued and aligned though. Will be picking it up tomorrow and undoubtedly be like "Oh, that clunk is gone" "Oh, the car really wants to drive straight" "Oh, that pedal feels better" "Oh, it feels like I've gained 25hp" "Oh, the handbrake works now" It should have been a sign that the new Project Mu shoes had 3mm of pad depth on them out of the box, and the OEM ones from 25 years ago that we took out also had 3mm of pad depth, implying the issue was not, and never was the shoes, but we put that down to it not being adjusted correctly. It wasn't, but it wasn't even adjustable at all given one side was boned and the T Junction of the cables was on a 45 degree angle, the non-working side being the one on the massive angle. Obviously when I had adjusted it and reset it and re-tensioned it I had either got it stuck or something along those lines. Oh well. Live and learn and absolutely could have been catastrophically worse so I'm rationalizing it as a win, kinda. I also got the chance to measure the distance between rear rim and the suspension arm/shocks and found a 30mm rubber block only just doesn't fit there. Which is great to know before ordering wheels, when I assumed 30mm was easy. The man with the Porsche adapters has rims that use 23.9mm of that space, so it's safe to assume I have between 23.9 and 29.9mm of space there to play with on the inside. The wheels looked pretty stupidly pokey with the 20mm spacers on the rear, only for me to find that the studs come out another 12mm and the wheel doesn't actually sit flush with the hub because you're supposed to cut your original studs. The wheels do have cutouts that kinda accomodate it, but not fully. So my 20mm spacer was anywhere between 25mm and 35mm. ~25mm and send it will determine on where the wheels sit with the spacers on. When I put the pads in for the track day I will mess around with spacers (with wheels that do not clear studs properly when mounted to spacers) and do more math, for the last time, for the 7th time.
    • Lucky pick up Best to find these things before something horrible happened to the yoke flange thingies I would hate to think what would happen if it dropped the tailshaft  Hopefully the holes are not flogged out in the yokes and it was just the bolts that got munted  As for the hand brake.....ouch, look like the disc got rather hot, and I assume smokey, I recall when I had a front caliper seize on the Commodore, there was lots of smoke and the disc was glowing cherry red when I was able to eventually stop and have a look, and stopping a big heavy car, going down a big hill with some rather high RPM down shifts and some hand brake action is something that makes you think hard about life
    • One of the things that never seemed right was the handbrake. Put in some nice new Project Mu shoes. We figured the rears were out, so why not. We're right there. My handbrake never worked well anyway. Well, this is them, 15km later. 67fdcf94-9763-4522-97a4-8f04b2ad0826.mp4 Keen eyes would note the difference in this picture too:   And this picture: Also, this was my Tailshaft bolts: 4ad3c7dd-51d0-4577-8e72-ba8bc82f6e87.mp4 It turns out my suspicions that one side of the handbrake cable was stretched all along were pretty accurate, as was my intuition that I didn't want to drop the tailshaft to swap them on jack stands and wasn't entirely sure about bolt torque. I have since bought the handbrake cables which have gone in. I'm very glad that I went to my mechanic friend who owns an alignment machine to get an alignment before the track day, because his eyes spotted these various levels of "WHAT THE f**k IS GOING ON HERE?". Turns out the alignment wasn't that bad, considering we changed the adjustable castor arms out for un-adjustable castor arms, and messed with the heights. Car drove pretty good with one side of the handbrake stuck on, unbleedable rear brakes, alignment screwy, and the tailshaft about to go flying and generally being a death trap waiting to happen! (I did have covid) (I maintain I adjusted the handbrake correctly, but movement caused shennanigans and/or I dislodged the spring on the problem side somewhat, or god knows what). G R E G G E D
    • Very interesting, im not sure how all those complications fit in to running a haltech instead of a stock ecu but I'm starting to think I'm a bit out of my league.
    • I just put 2 and 2 together. This is a Neo converted R32. The Neo ECU (in concert with the R34's AC controller) runs the AC quite differently to how the R32 ECU and AC controller do it. If you just drop it all in, it won't work. There is some tricky wiring required, including changing to the pressure switch that the Neo controllers want to see. I don't know what it is, because mine was done by a guru. It was a year or so after I did that transplant before he worked out what needed to be done.
