I'm considering writing a simple how-to for people interested in attempting astrophotorraphy with both digital and film based cameras. However before starting the project I'd like to guage how much interest there is amongst the users here.

Confession time.

Yesterday the moon was so bright I stacked my 70-200 on top of my 1.4X and newly acquired 2X teleconverter and pointed it at the moon. Took a few shots with 2nd curtain sync and manual focus, but auto exposure. Looked all right on the LCD. Downloaded the pictures to the computer - ARGH! Severely overexposed moon, because the metering was for the entire frame, which included lots of black sky. Couldn't save any of the shots.

Lesson number one: check the histogram, and use spot metering or exposure compensation -2 or something like that.

Yes, some tips would be interesting. But this is merely a technical exercise, not something I would really get into.

On the contrary, shooting the moon should be done as per daylight shooting.

If you want to shoot stars, expose for the stars. If want to shoot moon, expose for the moon. These 2 subjects are too many stops apart and cannot be accepted by film concurrently, which I remember only 6 stops. The naked eye can see much more.

Will be good... even if we do not have the require equipment, we still can learn something from it, after all it's a Knowledage base economy.. :D

Hope to see the notes or file soon.

Hi darr!

You are right!

Hello Streetshooter!

Use the Sunny 16 Rule on the Moon (ie. f/16) and use the inverse of the ISO you are using to shoot the moon.

Perhaps you would like to try again since youe are using digital. Poor me using still film camera......... sigh :(

if possible to shoot stars with D30 (with acceptable picture).....may be get an adapater for my friend's telescope and try out...

his telescope body itself cost over $5k, one eye piece for $3k, and i think all these accessories adds up together will be more than $10k already

wah...astronmomy is even more expensive then photography

I've started drafting the 'how to'
It should be ready in a week or two depending on my workload.

Stay tuned for further developments.

Astrophotography How-To Update

Just to let you all know the file's basic contents are now in place, am starting on the accompanying graphics and adding some extra information on advanced topics. At the current rate it should be completed in a few weeks time and will be a one stop resource for any photographer wishing to try their hand at astrophotography.
