I haven't been to AstroCafe for a long time, and just noticed there're so many good stories happening here!!

It's the festive seasons!! Hope everyone has had a great happy Christmas : D
This comet C/2011 W3 Lovejoy is a good Christmas present for us in the Southern Hemisphere.
It achieved its greatest brightness around the Christmas holiday - though I didn't see it ... blame the poor Sydney weather ... it has been cloudy and rainy

It has such a good name - Lovejoy
named after the astronomer with the last name as Lovejoy, what a good surename to have!!
With its "survival" after plunging into the Sun's atmosphere, it just reminded me of Love, Joy, and Hope in the festive season.

Wishing you all have hope, joy and peace in your hearts,
and days filled with warmth and love : )
Of course, clear skies!

I still stay up late every night till dawn hoping to see this comet.
I finally spotted it in the Christmas Eve morning by 4am, and captured it with camera.

It can be seen with naked eyes, even with bright lights in the foreground and poor seeing.
I have been wishing for the good weather and see if I can go to somewhere with premier dark skies to see it again.

These photos were taken on 24/12/2011, about 4am-5am.

hello Tony, long time no see.... :P

就像這裡說 "I wonder why major comets can be seen only in southern hemisphere these days……" :evil:

我在西藏能拍的,也只有10等以上的彗星。

另外從你的照片所見,下面是城市的光害,上面是繁星彗星,證明空氣質量十分之好。的確我發現對星野及深空來說,大氣透明度比光害的影響更大。

有沒有用130/780APO目視過? 彗頭形態如何? 以我的經驗,八五八六年哈彗星過近日點前,彗核很結實,外圍包著一層層次感很好的彗髮,我當年是把100/600小牛反搬到港島南區鴨脷洲樓下觀看而已,後來的Hale Bopp的彗尾很美,但彗頭結構也沒有那樣清晰的。

期待Tony更多彗星報告 :P

Wow, that's amazing!!

This 24th and the 25th morning had the better seeing.
I set up my telescope on the 25th morning and was ready to do some observation ...
then I found that the door frame of the balcony was blocking the eyepiece end of the telescope ... it's just a very narrow balcony
ok then ... I moved the whole set-up , but unfortunately the clouds came in ...
still no luck in the next two mornings afterward ... cloudy and rainy

the comet is moving higher up and will appear earlier in the night
hope i can shoot the comet through the scope in the later week : )

我的個人經驗,目鏡下的彗星,是動態的,這些大彗星,你看一段時間已有機會察覺到形態出現變化,我相信你把鏡開車一小時到郊區,已有機會看到畢生難忘的景象。

論拍攝,可能你的5D Mark II要改濾鏡了,有些機例如350D,以及現時的5D Mark II都是一代天文攝影名機,除非有固定天文台,否則我會像以前一樣,帶著5D Mark II走天涯的。

另外你有沒有考慮找個好的Barlow? 4mm在780上還是太低了,土星季節很也會到,可以試試300X下看土星的效果,色彩很飽和,對比度很高的。
