anyone 寫:i use the sky 6 .



有 RA 和 DEC 就好辦事了,謝謝前輩! :)
If you are using sky 6, my finder chart up there is a direct export from it.
Or you can use the FIND function-stellar-GCVS-cyg and you can locate ss-cyg directly.

anyone 寫:潘前輩,我都唔係好清楚該粒星在什麼位置,可否上載一幅相對位置的星圖;今晚有機會的話,影幾幅留個記錄,謝謝。 [跪拜禮]
I've posted finder charts here.
What star atlas are you using? The star atlas need to cover at least down to 10th magnitude.

Its position is:

Coordinates for SS Cyg: RA 21:42:42.79 Dec +43:35:09.9 (J2000.0)

Re: SS Cygnus - images from last night

Hi,
Despite the low transparency, I was able to get some images last night.

Telescope: Hokoon 0.5 m f/8
Instrument: Star Analyser grating ( 100 l/mm) attached in front of a Lumix G1 camera.

In all images, East is up, north is to the right.

Re: SS Cygnus outburst - call for observations

The AAVSO has announce that SS Cyg is in an out burst and has brightened 2 magnitudes in the last day. This is currently just a bit fainter than 9th magnitude. This might be an interesting object to observe witha Star Analyser or Lisa. Jeff Hopkins Phoenix Observatory I've prepared finder charts. pts

主題: 英文中學係未全校都講英文﹖

早在二三十年前既效果所謂既英文中學已經係掛羊頭賣狗肉~你估真係咁多小學生升上中學就可以用英語對答(國際學校例外)?好似我某個同學,係小學時數學係全級第一,但一上到初中一,數學老師堅持用英文授課,好多初中生都聽唔明,最後測驗同期考都有人唔合格,到下學期數學老師咪又係在老校既壓力下回復母語授課~[/quote] I agree. Once I taught for 1 year in a secondary school, teaching Form 1 Mathematics. Most of my time was spent on explaining the meaning of the ...
