Quake3World

Not too bad an effort.

AndyMan was the astro-photographer wasn't he? Searches.... Yes on this link... viewtopic.php?f=1&t=21230&p=968919&hilit=+AndyMan#p968919

Has Geoff drove off a cliff yet?

First pic was probably something like F/5.6 1/100. Second pic was 17mm F/2.8 at 25 seconds on a tripod.

Why is it so blurry if it's in a tripod?

Probably because the earth is rotating and 25 seconds is long enough to catch that fact.

cuz lens was so open it had narrow depth of focus field dummy

Relative faster speed at the Equator and less as you get closer to the poles too.
I just love the science here in Q3W

And a Wiki read for your reading pleasure

Agreed. Both shots look blurry. If you're shooting from a professional rig, there is something wrong.

We're off to Cuba tomorrow. I'll be shooting from my google pixel for reference.

Gwamps should teach a photography course, he could call it "Tacky and ugly phone pics of tacky and ugly things + cheap HDR filter 101".

Is Spazda upset with his baldness again?

lol, no one cares about Gramps Cuba trip.

Hey Geoff...

Oops, looks like you've just showed yourself up again

Na, should show small lines as the view rotates. Seems to have moved slightly on the pod which does happen.

Not dissing it, it's not easy to get nice starfield shots especially when planked is trying to use focus fields for objects millions of light years away

Pretty sure it's just the rotation of the earth. 25 seconds is the max exposure minimizing trails using this focal length, though it still shows up. 20 seconds ends up being a little too underexposed. I also set the camera on a 2 second delay to ensure it's not my hand leaving the shutter release moving the camera.

no dumbrain 2.8 and 5.6 is a deep field of focus?

dumbrain u dummy

Again, not having a go just saying it's not sharp.

On my slr there's a mode to turn off the mirror and stop it flipping and only use the focal plain shutter. Helps reduce vibration, could be worth setting as a short cut? And keep the ISO at its lowest if you're not bothered about rotation.

You really are washed up. Shame.

Re: What is new in your little world?

I went for a simply lovely 3 hour beach walk this afternoon... Simply glorious weather

Not a fan of beaches. Once you've seen five they've all the same.

Edit: but in keeping with the topic - I've just renewed my passport for the low low price of £80 and applied for my two lads first passport for the low low low price of £115.

Thought my flying with work days were over (hoped) but I'm off to visit Canon in Holland next week. Hopefully I'll be able to get my 24-104mm fixed...

Where? I know they have an office in Nootdorp (close to The Hague) which is like a 15 minute bicycle ride from where I live.

newtvillage.

Nutville?

Sacktown.

Nutropolis

Venlo, think it's one of their large marketing buildings. I think i'm there for three days of intensive training/drinking/getting high.
