virgin attempt on moon and some star shot

basically the only PS i did was to superimpose 2pics together due to the VERY different exposure settings.

shot with 70-300mm VR lens at 70mm x1.4 TC( lazy to remove it from an earlier shot) VR off.

moon was shot with F8 1/100, star shot with F8 8secs

hi opteron,
good to see you here. the picture looks fine for a "virgin" attempt. you might like to get more focal length for a bigger moon next....but this would be good for taking conjunctions (say with Venus and the moon together, etc).

Beautiful shots.
I believe the star was Antares?

Btw, speaking of conjunction, July 1st (after sunset) is going to be fun. Saturn and Venus will be pretty close in the sky.

thanks for the encouragement.
i wanted to superimpose a 420mm zoom moon on it but my CCD cant resolve the moon surface well.

thinking of changing the body.

sorry man, not sure what star it is. only told by my dad some bright star was making it's appearance beside the moon.

If you took the pic on 3/5 around 10pm, it could be either Antares (red) or Jupiter (golden). If it was on 4/5 same time, then it was more likely Jupiter becos Antares was very close to the moon then (around M4 position).

Hi,

thinking of changing the body.

It's not the camera body fault. There are a few things that will affect the Moon image at longer focal length:
1) At longer focal length, a bit of vibration will blur the shot, such as the movement of the DSLR mirror. Try enable the mirror lock-up if available or use a faster shutter speed to reduce the vibration... basically around 1/(focal length of lens)s.
2) At longer focal length, the Moon will be blur easily if you shoot the Moon on a no tracking mount, such as normal camera tripod, due to the earth rotation and Moon movement. Should not be a problem if your shutter speed is fast enough.

I think that should be Jupiter... the Antares is very near the Moon at that time (Saturday, 05 May 2007 0200-0300) ... basically in the halo of Moon.

Have a nice day.
