Too easy

I was out on my front deck testing my new 15x70 binoculars the other night wishing the Milky Way wasn't straight overhead.

I walked inside, grabbed my camera and put it flat on it's back on a board that I set across the corner of the balcony railing. So the camera was pointing straight up. I used the self-timer. In 1979, a one hour exposure on high speed ektachrome film came out with just a pale impression of the Milky Way

Pentax K1 ISO 800 10s
Pentax M 50mm f1.7 @ f2

These modern sensors are ridiculously sensitive.

That is a fine effort indeed Joe for such a simple procedure, looks good, and well done indeed.

That's stunning Joe!
You didn't mention where you live any more than 10 seconds and the entire camera mechanism and lens is frozen. I spent 4 winters in Young (sadly 4 summers too, I don't travel well in the heat). The winter skies were AMAZINGlY clear. I lived in Emily Street on the golf club side of town with minimal light pollution back till April 2000 but I didn't spend much time out at night in winter with a telescope or camera though I only had 35mm like most people then.

Hi Leo,

I'm not sure what you mean by, "You didn't mention where you live any more than 10 seconds and the entire camera mechanism and lens is frozen." Are you saying that your camera doesn't work below zero?

I've used my Pentax DSLR's down to -23C in the Arctic without problems. My Liquid Crystal display freezes below -20C but the camera still works fine you just can't preview or read settings. You can still see settings inside the camera. Certainly no problems operating the cameras in SE NSW between 0C and -5C.

Young has more LP these days than when you lived there however, I live way out of town, sort of midway between Young, Grenfell and Cowra closer to Young. We got a -5C last week but that's rare and compared to Canberra, it's always several degrees warmer. My house is set up on a hill above many fogs not down in a frost hollow. Really big fogs do get up here but most just sit down below.

On the 2015 LP map, I'm on a border between a notional Bortle 1 and Bortle 2 zone. Actual conditions vary from Bortle 1 to 4 mainly depending upon sky transparency.

LP hasn't been increasing much over the past decade around here. Young LP has expanded to the east but not north. Rural land isn't allowed to be subdivided limiting expansion to the north.

Cheers

Joe

It was a joke Joe. I'll never forget that cold wind sweeping straight off the Snowies and blowing through Young. Attending TAFE from 98 through 2000 while studying fabrication engineering (hydraulics and pneumatics and machining at nights) I'd spend my breaks out in the shared TAFE/High school quad grass area where I could find a quiet spot to sit and enjoy a coffee and a smoke . It would be bloody freezing.
It was funny, when I told friends I was moving to Lithgow they all said it was so cold, why would I move here. It's nowhere near as cold as Young.


I did some work helping a TAFE teacher (running his own welding business) out at Quandialla. I got to do the maths to design the cones for grain silos being removed from the earth rings. The skies there were remarkable. I regret turning down the offer a free house to live in on the head of the local grain corps property. It was a very hot dry place in summer and a single spark from an angle grinder through a 3mm hole in a silo wall resulted in a largish fire which took some getting under control using whatever we could grab before it spread to grain storage silos.

Cool shot Joe, looks great.

This was 40min on Ektachrome at F2.8 in 1984 (this is a scan of an old print)

And each of these panels was 30min on the same film (slightly out of focus photo of a glass covered display)
