Mandii,

Thanks a bunch for sharing your photographs. If I recall correctly, you are using a 4 inch Newtonian on a motorized EQ3 mount. Good work.

I find that DeepSkyStacker (DDS), seems to align stars better than Iris or Registax for photographs of nebula, star clusters, etc. DDS is freeware and easy to use. You may want to try it.

Ill be honest here. I dont understand your presentation. Infact its a little bewildering.

Deep sky Object photo list
Continous observation and continous photo recording .

LOL - ok ok.... I get it but why the pyramid and other ancient sculptures and so on. I will say you have the most unique posting approach Ive ever seen. At anyrate, I enjoyed scrolling through your images. Nice detail on Jupiter too.

Night sky is full of mystery . Especially those deep sky objects .. . I use simple or primitive equipments , the EQ3 mount with one motor unguided , 4" newtonian and a meade DSI-I . I admire the ancient astronomy , such as the ancient pyramid , that is also primitive and mysterious .
That's why my each DSO photo is attached the pyramid ,it represent the primitive and mysterious .

2ndly , some of the photos attach the star chat , these star chat are prepared and printed out before the actual observation night , for my manual GOTO to find the objects efficiently . To me , in order to capture an object , Manual GOTO is important and very fun . That's why I always attached the star chat and the actual object photo together , to combine into one single completed observation note .
And that is only talking about long time ago( half year ago) , I did it in such way , recently I am getting lazy , though the manual GOTO is still using , but just skipped the star chat picture , to make the final observation notes becomes more simplier and neat .

Mandii, you have come a long way from pictures of leaves.

Definately you have Mandii. So glad the wind done no harm to you and family and your Dome.
Keep up the good work.
Clear Skies

Thank you for the photos and clear skies!

Wonderful images Mandii!
Keep up the great work!




MANDII : Today, 09:22 AM
Thank you everybody !!
I had never tried to catch up 4 DSO in a single night(26th of DEC) before , ha ha very exciting and happy indeed ! The polar alignment by drifting technique did work very well one months ago , because of this , I can find the objects very accurately and efficiently , by using the Manual GOTO method . They can be seen within the FOV of my eyepiece by just turning the RA and DEC circles , just one time turning can reach their position !! And catch them !! very accurate !!

I will keep on doing in that way , The MANUAL GOTO , and thanks all of you to have a glance on my photos . THANK yOU !!

Nice stuff.

Hi Mandii - watched your ob construction with great interest on Observatory Forum

However I think you may get a better response with your images[if you want one?] on the beginners imaging forum. Also you are mixing here deepspace with solar system imaging and there are separate fora for each of these subjects in CN - hope my comments are helpful

You have great enthusiasm


MANDII : 02/05/11 11:33 AM
Thanks nytecam,
I am not sure this is the right sub-forunm to put my thread in . Cause I just noted the word "Deep Sky Object ". And it is really a deep sky object observation report . Anyway , I can't change it anymore .

Nice Work!!!!

Keep it up.

作晚天气有好转,也有个4,5成清吧,便在试用订造好的鱼骨板。
上次看土星的时间是去年三月份，用DC目镜后拍，拍到一粒不怎么清的黄豆那样。
作晚也试了2X 和3X 巴罗，3X 不够清。不知道是天空问题，还是那巴罗不行，还是什么了。

这铁柱上倆星期前自己设计清楚，画好量好图给深圳订造,费用一共才三百块，包上颜色，
还连双筒的支架也给我免费搞好一个，其间完全不用我费心，这样的服务实在找不到别的地方了。
前几天假期我一个人便到深圳把它拉回来香港 ，就那样把底铁盘上几根暴炸罗丝于地板上，便OK了，效果我非常满意。那天搞好的时间便顺便用手机照几张留档。

设计理念：
1.铁柱能高底调节，水平调节，适合不同赤道仪时作高底调整，太高太底都不行,目前调一定高度时能使赤道仪的极望看到北极星。

2.铁柱在天文台里固定的位置是要使赤道仪的纬轴（望远镜的中间）的中心点与圆顶的中心点对齐，而并不是铁柱放在圆顶的中心点正下面。因为有6公分之差,那样才能使望远镜有较大的活动空间,这点以前用脚架时发现的。

3.铁柱顶盘要能拆,不能焊死,因应日后不同赤道仪时只要把顶盘拿去改下罗丝的孔位,便能方便更换不同赤道仪使用。

4.铁柱中间空心,目前放沙填满,以减少微震。

This is an Iron Pillar I installed recently . Self-design and tailor made in China( shenzhen ) for only 300 dollars .Body weighted over 20KG and Loading over 100KG is no problem as said by the shop makers . It can be adjusted the mount's horizontal water level because the ground is not plain enough .You can see the bottom two plates is clapped together by 4 big screws in controlling the maximun 10CM adjustment in height very precisely . And the mount can be put over it in different height levels , for better visual effect .In reaching certain height , the polar star can be seen in the polar scope , that's necessary for polar alignment. The pillar is firmly anchored on the ground in the DOME at a position being choosen that the center point of the mount's DEC axis is passing through the center of the DOME . Not the pillar put dirrectly under the center of the DOME , that can be resulted in maximun space for the telescope in moving all around freely . I had tested different telescope rotating positions without problem . Since it's a hollow pillar , I put much sand inside to strengthen it's resistence to small vibration , make it more stable during astro-photography .

日本MIZAR望远镜最近也搬来深圳用,没为了别的,就为了找找星,喜欢找星。说起来我为什么会那么喜欢找星,这个也不太知道。可能和读中学一年级自然科学时第一次在实验室接触显微镜有关吧,香港初中一年级就开始有进入实验室,当时我有一段时间下课便走到图书馆里看一些这方面的书,微观生物的世界令我印象深刻。而现在利用望远镜,恰恰相反看的是宏观世界,遥远广阔的宁宙,目镜里看似平凡的东西,欲又不平凡。本是两回事,却又是同一回事,就是在那里找自已想找的东西。。。

把其中一部望远镜搬来深圳早在去年年中就有这个打算了,一直没真的去做,现在终於搬过来了,因为有时候我一家大小也在这边的。我会在阳台看,阳台能看东和南方的天空,或且有时会上楼顶看,楼顶的北极星幸好未被山挡住,我就住在顶层。

深圳是个年轻活泼的城市,年轻人多,我住的这个房子今年也有十一个年头了,深圳这个地方有著许多许多我的回亿 ,曾经走过的街角,有美好的回亿,也有伤感的回亿。我爱香港,也喜欢深圳。回想起,当年真没想到许多年後的今天,竟然会在这个土地上看起星来了。。。
