No.8 )

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 .

NO.1 )

No.9 )

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 .

NO.7)

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 .

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.

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 .
