Any Experiences With Astro Photography?

Mon Apr 03, 2006 7:34 am

Last night afforded a decent opportunity to catch an interesting event, that is, the crescent moon was just above the Pleiades as they traversed the night sky. Using one photo, ISO 1600 f/8.0 1/400th of a second to accurately expose the moon, then one photo ISO 1600 f/5.6 1/50th to expose the stars, then superemposed the correctly exposed moon over the completely overblown moon in the pic with the stars visable rendered this image:



Both shots taken at 400mm with the 20D and Sigma 80-400 EX OS APO.

I'm going to try again tonight to see if I can get anything better, hopefully the moon is close enough to the open cluster still, anybody else have any experience? If the moon moved in the right way, then tonight it could be a little farther back and hopefully right inside Taurus, so I might be able to get a shot with the moon and the Crab Nebula visable together, that'd be kinda tight.

Nice shot, I see you captured exactly seven of the sisters!

I didn't realize it until I got into astronomy, but the moon moves quite a large distance, with reference to the background stars, from night to night (about an average-sized constellation a day); so tonight it may not be well-placed for what you are thinking of.
You know the gear is up and locked when it takes full throttle to taxi to the terminal.

Yeah it's probably not going to be quite as close to the ecliptic as it was last night, we can always hope though eh?
