Full Moon - 2 Apr 2007

Post by **Airconvent** » Mon Apr 02, 2007 11:38 pm

I think today marks the first day of the Qingming festival where the Chinese visits their ancestors' graves to clean them and make offerings. It also happens to be the 15th day of the lunar calender (where the moon is the roundest and brightest). Grabbed my K100D camera and Sigma 500mm Mirror Lens to try some shots on the moon.
The full moon is more challenging than my previous crescent moon due to the lack of shadows and glare but here goes anyway. No processing done. Just cropped them.

Thanks to Weixing!
I planned to take photos of the moon on the way home when the moon was just rising as an orange sphere but totally forgot about it until I received his sms on how clear the moon is and I was reminded!
Actually the moon is quite blurred today...with a thin layer of clouds/haze obstructing it.
Looking at my efforts, now I know why people do mosiacs. Its simply not possible to take a razor sharp image of the moon as a whole. They always look so soft.

Hi,

Can la... a "slow" scope + a mirror-lock up camera will help a lot. You can also used stacking + image processing to make it look sharp.

Below is a moon I took last year and an example of over-processing... ha ha ha

Have a nice day.

i do not even qualify as a newbie...maybe somewhere below newbie!

my logic is there is only so many pixels in your camera. so taking small parts of it at higher resolution and then combining it will enable better resolution and image detail. of course I could be wrong looking at weixing's moon which is excellent!

Yes, this is correct... You can get very high resolution and very details image by using mosaics. IMHO, usually mosaics is used in the following situation:
1) You need a very high resolution image (such as making a huge poster) which most digital camera cannot provide such a high resolution image in a single frame.

2) You want to capture an object larger than the field your camera and lens (telescope) can capture without sacrifice the details.

Have a nice day.

Hi, I just uploaded a moon mosaic in the album. Yes the details are much better. But the sheer amount of work to take the avi files and the huge amount of hard disk space used and the uniformity needed in the processing later together with the piecing of the "jigsaw" together makes me a bit scared to do it again, hehe.
