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 .

TheFOV of this picture ( DSI plus 2X barlow ) this time is about 12" ,according to the indication on the moon map software . Starting fromnow, I can use this software to physically measure the FOV of anytelescope imaging system . And I can even measure the distance betweentwo points on the moon directly . In the old time , I can onlycalculate ( i.e. estimate ) the FOV , but now I can measure it directlyand PHYSICALLY with the help of the actual moon crators , this is veryimportant to me .

I am not using a web cam this time indeed .
282 flames is collected in about 5 minutes from DSI .
Comparingto webcam , Just several second can be collected for such number offlames in a video format . The shorter the time , the less therequirement from the mount's tracking . So DSI surely can cause moreshifting in image than the web cam . However , such image shifting canbe recovered easily from any image-process software . And DSI is moresensitive than my ordinary web cam , ( even the price is moreexspensive ) , thus , I may use DSI to take moon photo in future , andtotally replace the use of a web cam . Because DSI is more generic inmy situation .


Clear skies everybody .

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 .
Ipick up the moon map , nevigate the moon surface for nearly 15 minutes. And center the eyepiece after I can locate the Archimedes . Then useweb cam to shoot it . Finally make the picture by Registax software .

The moon is rising up the hill , behind a tree .

Last night the moon was very bright , actually not a good time to take a image ,atmosphere was not stable as well .

Thistime 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 toobig magnification for my 4" telescope and blur the image indeed . Butthis time with 2X barlow , the image is still acceptable . I amsatisfield with this cheap price Barlow very much .

This timethe target is the "比利牛斯" mountain chain , the BillyNews mountain chain. You can also see some nearby crators , and such magnification is justenough for me , compared with those taken previously without the barlow

Finally, this time I write my report on the next day of observation night . Sothat I can have plenty of time to prepare a better image . Before Ididn't pay too much attention on the image processing indeed , cause Idon't have much time to try on the night time . So,this morning I amfree in office and try more on the software REGISTAX . I found it hasgood tools to make the image better and sharper . That's a good andneat software .

拍月面也拍了快一年了,图片清不清好不好，这个器材是那样也只能那样了，能改善的也不多。
一分钱一分货，一分天气便一分钱，不能免强，现在该是时候搞搞新意思了。

我想加强月面地图的作用，因为我觉得月图不只能做到目前那些。
目前是观察当晚，打印月图出来，边看月图边找目标，然后把目标移到12分左右的视场的中间位置，进行拍摄纪录。
但问题是这种作法，是漫无目的地随意找目标的。
现在要加插一种玩法，要更加体现利用月图来有目的性的寻找目标的玩法，就是要予定目标拍摄。
予定指的是要在观察当晚之前的时间里，予定好要拍的位置，予定好一个目标，不能随意拍个目标便算数。
得先把月图造好，然后于当晚打印月图出来进行细致的观察和拍摄，而必需要找到拍到该目标的位置所在。
这样新做法和目前比较上来完全是倆回事的，难度也提高好多。

我的第一个目标是 Rupes Recta .
该图区的视场是11' , 和我现在用web cam 或者DSI要差不多，DSI加 2x barlow 能达到12‘， web cam 就不用加barlow 都有12'了。我不知道我现在的器材能不能解像到那条Rupes Recta的裂纹，试试看。


计划即时生效 !

English version :
My next target is Rupa Recta .
There is a crack line on the moon map .
The moon map of Rupa Recta is prepared well right now , FOV around 12' , as shown .

So next time I need to find it out this target , and move it to center of the FOV , and take image of it . It's totally different to what I did currently , currently I choose any object to shoot it , no target actually . So it will be much more challenging because I need to shoot the ONE and ONLY ONE target on my next time observation .

Let's see it , For the moment I am not sure my equipment can resolve the crack line of Rupa Recta .

這個是不是之前同好之間常拍的峡谷?
我忘了叫什麼名字了

我只是偶尔在月图上发现这个位置有一条裂痕,它叫”Rupes Recta" , 我觉得很特别，不清楚有没有人拍过它。
你可以对比那个人的照片和这张月图，看上面裂痕处周围月坑的位置和大小是不是和月图对得上就知道是不是那个了。月图是不会有错。

《月面观察新方向定位》

月面观察有了新的开路方向,这观察包含目视和拍摄。
可谓找到了一条长久,实实在在附合现状环境的一条宽阔的天文观察道路。
过去只有月面图，而要观察的目标是很盲目的，就是在月图上看看那里自己觉得好看，比较特别的景点，然后就按月图来进行观察。今日得到香港天文论坛里的一位资深天文观察前辈 Mr.David 的重要信息，现在可收集了更进一步的一些比较有名的月球景点资料库。这景点库就是Charles Wood's list of Lunar 100 http://www.astrospider.com/Lunar100list.htm 。

这景点库里有100个，我想日后就按这100个景点进行观察，配合现有的月面地图，预先在月面地图中找到所要观察的景点，定好月面地图的视场（一般是12分角，随器材改动），目标位置（正常是正中心）,和影像旋转角度（按牛反镜的特定方向）后，再打印月图进行观察，进行目视和拍摄，而观察的记录照片必需和原来月图的视场，位置以及影像旋转角度一致 。

我先按现在的月面观察情况来估算，一个月有一倆晚观察，一倆张的作品照片,那么最小50个月就能拍完这100个景点。也就说，光这景点库都已经能维持最小4年的天文观察乐趣了，而且是按目前的器材来算。过去是担心没天气观察，没什么好观察的天文素材，使天文的路很难走得下去，而自己又付出了那么多的心血，实在是有一点儿叹息。可现在很大程度上克服了这个问题 ! 克服了一个最基本最基础的问题 ！。


计划即日生效 ！

This was a very poor pic taken a few years ago by me.
http://www.imsc.edu.hk/pages/moon/rupesrecta.html

The moon is a wonderful target. In the last week or so I took out my 18" for many times, not for saturn because it is almost the same everyday, but for the moon. Last thursday, just me and an ex-student were observing and we spent more than 2 hours just on the moon. (Of course, the moon looked stunning in 18" at around 540x with Ethos 3.7.)

It is a shame that many people don't apprecipate the moon but it is easy to see why. There are so many targets that can look very similar, and one easily get lost. A good place to start is Charles Wood's list of Lunar 100:
http://www.astrospider.com/Lunar100list.htm

For those who have apple products, 'Moon Globe' is a wonderful app to download which is useful when using on the field. I frequently use it to demonstrate to my students what they are looking at and what they can pay particular attention to. Using this on iPad would be wonderful.

Cloudy Nights and US Astronomy :
<<A New highway to go on moon observation>>

This is my new plan on the comming at least 4 years time to engoy the moon in a practical ,sophistical way . In my past two years of astro activity , the local weather is not really good enough for advance types of astro-observation . Advance observation seems to be a bit too ideal in sense in my situation .Looking at the real fact in front of me , I decided to go on a way that is more sophistic , and more long lasting observation activity . That is : To collect the moon scenic spots into pictures in my comming years . That would be most probably one of my way to fully use my telescope , and the most basic way to enjoy the astronomy , under bad weathers ,and under probably even more bad weathers in the comming years of time .

There is 100 good scenic spots on the ground of moon in database of Charles Wood's list of Lunar 100 Lunar 100 . This is a good database I had found a long time for .With the help of Charles database , plus my current moon map software , I can prepare the target location map before the observation night . Fix down the map FOV( normally 12" under my telescope & camera ) , the target position and image rotation before observation .And take a picture of the certain sopts by the same FOV , position and image rotation during the observation nights .

According my current moon observation situation , one months I got 1 or 2 moon pictures , so I can enjoy the astronomy by the Charles database for at least 50 months or 4 years of time .


Plan come true Today !

The previous two completed planning objects were Straight wall/Rupes Recta and Villas Alpes .This is my third observation plan on moon .I give an index no. "Plan_03" to it , such that it can be linked together with it's actual observation report latter . From now on , I will plan the objects according to the charles wood lunar 100 , as I had said last month .


Object : CLAVIUS
Type : Walled plain
Plan date : 2011/05/16 10:01a.m

CLOUDY NIGHTS

TexasRed : 06/08/11 08:15 AM from Texas

Can anyone recommend a good map of the moon oriented like the view in my dob? Or a good book for getting started in exploring the moon?



MANDII : 06/09/11 09:55 PM
Well , this is a good topic to talk about .
In my idea , in order a moon map can be used by all kinds of telescope , and all it's pointing direction , it should have 3 kinds of views . Flip E-W , N-S inverted and most importantly it can be rotated to any angle . If anybody know this kind of software( I mean it can be rotated ) , pls teach me and thankful . We need to use software of moon map , not a copy of paper , because we can do many things in computer , like searching the crators by it's name , zooming view , taking picture of crators , or etc ... So a software of moon map is better and much more convienient than just a paper of map .

Why it depands on pointing direction ? In my actual usage of a newtonian scope for a long time , I found that the pointing direction of a DOB , newtonian scope ,except the refractor type scope , can cause the image in an eyepiece , to rotate to some angle . You can easily discover this image feature when you test even a fixed territoral building with a newtonian scope .

The image in eyepeice rotates clockwisely or anti-clockwisely , when your newtonian scope is pointed at different direction or angle . Of course in this test you have to locate the telescope in different position on the ground , such that the same buiding in different pointing direction , can be seen .


simpleisbetter : 06/09/11 10:10 PM from Republic, MO
As for software always being better and more convenient than a paper atlas, I'm not certain I completely agree. But if that flexiblity in software is what you're looking for, then download and install Virtual Moon Atlas. I run it, but I still prefer Rukl, the Lunar Field Atlas, or NASA maps.

--------------------
Steve


MANDII : 06/09/11 10:28 PM
Steve , I am using it , the virtual moon atlas , but it cannot be rotated . If you like paper , you can print it out from the that software at the time of observation .


Using computer has defintely another advantage , I am doing this kind of thing recently indeed . The advantage is : The observation can be planned in computer ! Before you are going to observe an object on the ground of a moon ( e.g crators ), you can do some kind of preparation . The preparation help you find an object more easily . You just save the picture that shows the nearby region of your target object . Or print it out in an paper . Or just save it as an picture to view in a computer display . And use it during the observing night . It save you much of the time at the observing night .


This is my thread for all your reference :
http://www.cloudynights.com/ubbthreads/showflat.php/Cat/0/Number/4268580/page/0/view/collapsed/sb/5/o/all/fpart/1


simpleisbetter : 06/09/11 11:40 PM
Hi Mandii,

Maybe I'm not following you in what you mean by it can't be rotated. If you switch to the Tools tab to the right of the screen (see atch pix), in the middle of that tab section you will see a block for rotation. You can select both default orientation and direction of rotation. It's always worked for me. Now, I will say I've noticed that when you switch to eyepiece view, it seems to want to reset to default orientation, but once eyepiece view is turned on you can simply rotate it until it matches your FOV in the eyepiece. I hope that helps.
