30 minute exposure Cerro Tololo Inter-American Observatory 4-m Blanco Telescope

This is the first of a series I recently took at CTIO. Let me know

your thoughts and give suggestions for improvement.

I love star trails. I particularly like here the streak of blue just above the observatory.

That's the Milky Way!

This is my beautiful Country !!

Thanks for share this amazing pic.

Very nice - i tried this 2 weeks ago in the mountains, no moon with 200 iso and at f 4. the end result did overexpose completly. Wonder what was your settings her?

F5.6, 30min exposure. The moon came up in the last 5 minutes or so, illuminating the dome.

great control of exposure & timing. tremendous artistic effort. beautiful photo.

Wow, this is fantastic. Your timing is pretty amazing too, with the moon lighting up the dome just a little. Not a situation that gives an easy second chance.

great shot, love the startrails~!!

If i had to guess, i would say 25/30 min exposure.

Chad, I'll bet the neg was more than a bit "thin" (underexposed), judging from the grain which, IMHO, spoils an otherwise wonderful shot. You mentioned here http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=00EqiY that you processed it yourself with the Tetenal C41 kit: Do you think the color developer may have been weak (or not quite at 100.0F), leading to unintentional pull processing?
