Subject: 20030827 Mars


Dear friends,


This is my first mars image after I returned from US (Actually my last mars image was taken on 18 July). Fortunately the sky turned to be clear when Mars at closest last night. Seeing and transparency were 6/10. The coming few days will be clear too and I wish I can capture more shots.

Subject: 20030828 Mars opposition (natural processing)


Dear friends,


Sky was clear last night when mars approached its opposition. I was able to capture some portrait for mars, the seeing was average but very happy to see the atmospheric features is more obvious than 27 August. This time I use very natural processing and try to show the most beautiful view of mars instead of just going for detail with hard processing. The north polar hood and limb haze above Syrtis Major at morning side is very well shown. Wish you all like it.

Subject: 20030829 Mars (bad seeing)


Dear friends,


Last night the seeing was not very good. Very turbulent air and I could only capture a few clips that I was confident to reach the focus. A new Typhoon is formed in western Pacific Ocean and will affect Hong Kong on Wednesday, wish I could capture some better shot before I unload the telescope from the mount.


Kind Regards,

Subject: Reprocessed 20030829 mars (manual selection)


Dear friends,


I have manual selected 200 raw frames out of 1200 from the same raw video. The image sharpness and detailing improved a lot. Artificial intelligent is not wise than human brain. Please feel free to comment on it.

Subject: 20030830 Mars

Dear friends,


The sky was clear last night but quite hazy. Seeing was quite good. Attached was the image captured with 12.5" F6 Newtonian and ToUcam as usual. You can see the Olympus Mons and the orographic cloud (above Arsia?) at the evening limb.


Kind Regards,

Subject: 20030830 Saturn


Dear friends,


Attached Saturn was captured in this morning just right before sun rise. As we need to connect the camera and point to saturn before it hided from the sun light, my friends Fat Pang, Billy and I took the shot with team work. I am sure this morning was my fastest pointing speed to the planet with ToUcam Pro. 


Seeing was just fair and transparency was very low.


Let's welcome Saturn

Subject: Another 20030827 Mars (processed it while typhoon is approaching)


Dear friends,


While a very strong typhoon is approaching HK directly. I am processing another 20030827 mars processed from one of the best AVI. I put two processed version, one is more natural processed and the other one is enhanced. Thanks for the suggestion from Weileong


BTW, you may be interested to see the typhoon image from the following link. maximum wind speed is 190km/h directly approaching HK.


Seems the HK amateurs should setup a scope and imaging through the "eye" of Typhoon.
