刚刚试玩了下Registax 5.1 ,把AVI叠加200张看看，用法要比IRIS简单容易得多。
今日下载了好几套通用软件,现在web cam 拍月基本上有4个方案已定下来,目的是要拍高清和放大倍数高(MIZAR 4“ 最大定为120倍)的月面。
1. 用谱通web cam ，以通用的avi拍录软件，在registax/Iris 叠加成照片。一般web cam 估计相当于focal length 大约在8mm的目镜那样，因此放大数约在7，80倍。还是不够大（差4，50倍），因此要试在0.965"的2X barlow(160倍）下的情况。1.25"的3X Barlow 达到240倍估计成像不行的，因为在目镜里都已经那么差。
2.用DSI I 拍,以前拍完是没有叠加的,现在要叠加起码100张以上看看,但放大只有70倍那样是肯定的,因此要想办法在0.965"的2X barlow 下试验。
3.购买全新的Philip spc900nc , 连1.25" adpater 只要680 RMB 。
已与买方联络好，但估计没那么快决定要。此web cam 性能肯定要好很多，不过放大倍数方面估计也只能是70/80倍那样，因此也要 想办法再放大多一倍才够。像上面的用0.965" barlow 。
4.用高压拍录软件，得到高压缩后的AVI，再把AVI转换一些高清的档案格式，比如DVD，Mpec,APPLE TV 等等，然后用高清播放器软件直接在动画中扑捉 JPG照片,那样便有可能直接地可以得到高清的照片，而并不用任何叠加处理，当然也可以再叠加。目前这只是构思。
其实理想放大是200倍起码的,但那是MIZAR镜没法做到的了,只能看日后的ORION 6" 牛反了,但该镜是计划半年后才会用的。因此现在只能那样，但以上的更新动作，也要同时考虑到日后Orion镜的配套上来。
今晚想了一个最简单又可靠的方法就是把web cam 固定到DC万能架上,那样便可以插得上1.25"和0.965"的目镜座或者Barlow 上了。
现在都完全准备好了，就等好天月亮出来。
今晚终于有空试了下web cam .
没加 barlow 放大,云厚。
果然比用DC目镜后好 !
向实践派学习

It's long time no take an astro picture ,
cause recently not always stay at home .
Tonight , I come to take a picture of Archimedes .
I pick up the moon map , nevigate the moon surface for nearly 15 minutes . And center the eyepiece after I can locate the Archimedes . Then use web cam to shoot it . Finally make the picture by Registax software .
山名你都认识，在那差的
有了月面地图，便有根有据。
图中点4还是当年1971年阿波罗15号登陆地点呢。
你大概在照片上也能看到那地方的位置了。

Last night the moon was very bright , actually not a good time to take a image ,atmosphere was not stable as well .
This time I tried my new bought 1.25" 2X barlow together with the web cam . Previously I had failed to capture a good 3X barlow image , cause too big magnification for my 4" telescope and blur the image indeed . But this time with 2X barlow , the image is still acceptable . I am satisfield with this cheap price Barlow very much .
This time the target is the "比利牛斯" mountain chain , the BillyNews mountain chain . You can also see some nearby crators , and such magnification is just enough for me , compared with those taken previously without the barlow
Finally , this time I write my report on the next day of observation night . So that I can have plenty of time to prepare a better image . Before I didn't pay too much attention on the image processing indeed , cause I don't have much time to try on the night time . So,this morning I am free in office and try more on the software REGISTAX . I found it has good tools to make the image better and sharper . That's a good and neat software .
No.8 )
Dear Joe ,
I see . Thanks for your care
So the wind last night had passed and left .
I had found a chance to take a moon photo last night .
It's the Mare Imbrium , a large oceanic area on the moon .
You can check several apparent areas as well from the moon map I provided , I had bold it in Red blocks .
The FOV of this picture ( DSI plus 2X barlow ) this time is about 12" , according to the indication on the moon map software . Starting from now, I can use this software to physically measure the FOV of any telescope imaging system . And I can even measure the distance between two points on the moon directly . In the old time , I can only calculate ( i.e. estimate ) the FOV , but now I can measure it directly and PHYSICALLY with the help of the actual moon crators , this is very important to me .
I am not using a web cam this time indeed .
282 flames is collected in about 5 minutes from DSI .
Comparing to webcam , Just several second can be collected for such number of flames in a video format . The shorter the time , the less the requirement from the mount's tracking . So DSI surely can cause more shifting in image than the web cam . However , such image shifting can be recovered easily from any image-process software . And DSI is more sensitive than my ordinary web cam , ( even the price is more exspensive ) , thus , I may use DSI to take moon photo in future , and totally replace the use of a web cam . Because DSI is more generic in my situation .
Clear skies everybody .

The moon is rising up the hill , behind a tree .
This moment leaves silently and fastly .
The picture was shooted at 7:00p.m tonight , within less than 10 seconds time .
I focus on the tree , and let the moon become a blured background .

COOL! --- thanks for posting them. You may be able to get better use out of the DSI camera by following this planetary photo instructions:
AutoStarSuite.Net - Planet settings for DSI color cameras
are you using the free Registax software to stack your photos?

Good work, MANDII. Sounds like you have been busy and having fun making the images. Thanks for sharing your work.
MANDII : Today, 11:21 AM
Thanks Joe for your more detailed DSI information , yes , I am using the Registax 5.0 .
That seems to be a good software , and easy to use it .
And thanks Carnevali as well .
Recently , the night is not so clear , always misky night , I can't see the other stars , except the the moon , and Jupiter .
Hoping Clear skies to all of us .
