[table=98%][tr][td=2,1][font=Arial, Helvetica][color=black]About this Image[/color][/font][/td][/tr][tr][td=2,1][font=Arial, Helvetica][color=black]M83 was classified as intermediate between normal and barred spiral galaxies by G. de Vaucouleurs, in his classification this is SAB(s)c. It is showing very well defined spiral arms and displays a very dynamic appearance, appealing by the red and blue knots tracing the arms. The red knots are apparently diffuse gaseous nebulae in which star formation is just taking place, and which are excited to shine by its very hot young stars. The blue regions represent young stellar populations which have formed shortly (i.e., some million or some dozens of million years ago). Between the pronounced spiral arms are regions with fewer stars. [(OW1VJEd;JuP?
Dark dust lanes follow the spiral structure throughout the disk, and may be traced well into the central region to the nucleus measuring 20" diameter. This nucleus shows strong emission lines. It is composed of an older yellowish stellar population which dominates the whole central region, and extends along the barlike structure.

It forms a small physical group, the M83 group, with the peculiar radio galaxy Centaurus A [/color][url=http://panther-observatory.com/gallery/deepsky/doc/NGC5128_F9.htm][color=black](NGC 5128)[/color][/url][color=black].

Because of the need for higher quality and magnification I soon upgraded to the Meade ETX90 which made for better planetary viewing.+y|1k6m"U\4s2t8U
In 1998 I joined the local astronomy club and acquired a C11 on a G11 mount.  Astro-related photographic film experiments failed, but in 1999 I successfully introduced a webcam for planetary imaging and motivated other colleagues of my club to do the same.  My wife Roswitha supported my new hobby fascinated from the endless variety of objects to observe and to image. [/size][/size][/align][align=center][size=13.5pt][size=4]To escape the painful setup installation every night I built my own 3m observatory beside my house 25 km south of Graz during summer 2000 in a semi-rural environment (mag 5 sky typical).  Another big step into deep sky astrophotography was the use of a digicam, first the Nikon CP995, then replacing it 2001 with the Canon D60 and 2002 with the Canon 10D.   A MX7C was used for autoguiding. [font=Times New Roman]My second high quality scope was a 4”[/font][b][font=Times New Roman] f/6.5[/font][/b][font=Times New Roman] TMB[/font][b][font=Times New Roman] APO[/font][/b][font=Times New Roman] refractor.[/font] Ironically most times I was guiding with the C11 and imaging with the 4” refractor. I accepted the lower cost and big chip size of the Canon D-SLR with reduced efficiency, as no reasonable priced CCD cameras were available up to 2003. To overcome the low quality of these raws I tried to compensate it by long multiple exposures and tricky Photoshop processing. By doing this I was pushing the limits of digicam imaging.  At the beginning of the year 2004 SBIG released the STL-11000, the first full frame CCD camera and I got one of the first models.  During the year 2004 I consequently explored mainly nebulas using theyM4\}0DQ$}m
wide corrected field of my TMB. Also in 2004 my wife and I did our first trip to Namibia, using most of the nights to image many fascinating southern targets with the 4" TMB and the STL on my mobile setup.[/size][/size][/align][align=center][size=13.5pt][size=4]Intense E-mail communication with colleagues all over the world pushed my experience in image acquisition and processing.  Another dream came true in early 2005 when after a 2 years wait my 16"
flR,Z].EZ"k Cassegrain from P. Keller was finished and installed in my observatory.  This was a big step forward and allowed for imaging objects of various sizes in both medium to high resolution. Because of the f/3 option of my Cassegrain, I tend to specialise in wider-field images.  Additionally, I am doing high resolution imaging using the STL-11000 with the cassegrain f/10 setup at 4 m focal lenght as well as with a firewire b/w webcam typically at f/20 for planets, Moon and Sun.  In November 2005 I was invited to speak at the Advanced Imaging Conference in San Jose, California
7f#b0s%Kl+yE4Sh.k;A where I spoke on imaging with the STL-11000. [font=Times New Roman][size=4]It was a great experience because I met many famous astro-imagers in person and enjoyed talking directly with them the first time.  [/size][/font][font=Times New Roman][size=4]Also in November 2005 I exchanged my 4” TMB against a TEC-140 f/7 APO refractor with field flattener to improve the resolution for my mobile setup. This setup was used intensely for astro-imaging during my 2 week's stay in Hakos/Namibia in Mai 2006. [/size][/font][size=4]?cO4t&^[xf}w

很牛。只是感觉星芒有点碍眼bbbb20

这辈子不知道还有没有希望到这地步

bbbb81 爽翻了！bbbb39 $k$P-KW Re n
我倒觉得星芒的感觉很好啊~

半米的镜子啊。。。

bbbb60 直接崩溃了

极度的震撼:o :o

谢谢LZ一下子送了俺这么多壁纸啊r2?P(Wz$q],Ye}
:lol

今天终于见识到什么是牛了...............:L

回复 12# 的帖子

:) 同感啊！:)

首先是seeing非常好， 其次器材非常不错， 而且后期处理也很出色。

这个只能用 非常疯狂来形容了

这个不知和OGS,RCOS相比如何?从效果看相当不错

Schedler代表了欧洲爱好者深空摄影的最高水准。Ufo:PCy7nl

op-s\H.k 他也是从一部tmb105+数码相机开始的，至于TEC140，至于16"RC，再至于远赴非洲，使用纳米比亚的20"。s&sfoo8[
6P%u A,]iw1v
器材比他好的大有人在，但没有几个人的作品能望其项背。为什么？v*X4S1eF:OLK|(C

Dl[*ei$A 其实深空摄影说简单也可以，因为好的器材准备好了，点几下电脑即可完成，难在知道在哪里架器材和知道怎么点击电脑。

太美了，佩服 佩服:) :)

草帽星系的那张照片几乎就是哈勃的水平。bbbb59

:) :) :) :) :) :) :) :)

革命尚未成功，大家仍需努力……:lol

我不太相信，这是业余爱好者拍的，会不会是从哈勃PS过来的？:victory:

太美了:) 太美了:victory: 太美了bbbb45

看了这个帖子，就让什么高桥、TMB见鬼去吧！哈哈bbbb70
