Subject: 20030909 mars

 

Dear friends,

 

The sky finally clear but the transparency and the seeing were not good. Attached mars image was taken last night at 17:19UT. Please note that the evening limb brightening was very obvious. BTW, the eye of mars (Solis Lacus) is looking at you now. :-) The sky will be clear in coming few days, wish to share more with you all!

 

Cheers,

Subject: 20030911 & 0912 mars

 

Dear friends,

 

Attached were mars images captured on 0911 and 0912 at similar CM. You can see the clouds changes over the north hemisphere from 0911 to 0912. Very strange seeing recently as the air steadiness was worsen while mars become higher. Too bad!!!

 

Anyway, wish you all like them

 

Cheers,

Hi KC,

 

Very nice to see such fine result obtained with your newly installed 10" Newtonian. The morning haze around the Solis Lacus is very obvious. I shall post mine to you later on.

 

Cheers,

Subject: Another 20030912 mars

 

Dear friends,

 

Thunderstorm last night, no new images. Just processed another 20030912 mars. This one showed very clear cloud features near morning limb and north hemisphere. The bright ice spot at the p. side of SPC can be seen too.

 

Regards,

Subject: 20030917 Saturn

 

Dear friends,

 

Attached was the saturn images taken in this morning. Saturn was around 50 degree from horizon but the atmospheric dispersion is enough to blur some details on the ring (especially for Encke minima and Encke division). However, the belt structure on the globe is very beautifully shown. Wish you all like it.

Thanks Christophe,

 

As I was totally exhausted this morning, I will take a good rest tonight and continue imaging on Friday and hopefully can get some better saturn shot.

 

Cheers,

Subject: 20031018 Saturn

 

Dear friends,

 

Last night arrived the observing site lately, so missed the god of war. No choice, wait for Saturn and Jupiter. Seeing was below average (4-5/10) and transparency was low (some haze). No encke division visible. The globe bands were washed out due to low signal to noise ratio. Two reasons: low transparency & too high focal ratio (5X powermate). I shall use the 4X powermate to achieve F27 and try in coming morning.

 

The south equatorial belt is vividly shown with reddish tone.

Feel free to comment.

 

P.S. I shall post the Jupiter shot later on. But very very bad quality as it was captured when it is below 30 degree.
