鏡神的那支應該冇咩問題。

As long as you do not have a big brand name for taxation, you should be fine for self made products.

Thanks for all's comments.

I agree that getting a van may be difficult for southern Lantau Island.

Actually, I usually go to Clear Water Bay to watch DSO (Mostly because it is closer to home. I always worry that the sky condition will change when I get to PTC). The eastern direction is very very dark, much better than PTC in any direction (although I have no definite data to verify this, which is a subjective impression and may be wrong). Except the western direction where light pollution is terrible, I generally can see my targets (mostly in the Messier catalogue) in the finderscope.

Since I usually have students to go with me, transporting equipment from car park to the kite area is of little problem.

However, sometimes the place suffers a lot from strong light from boats. But usually, it is okay because they are absent.

In fact, for first light, I will probably go to Clear Water Bay or PTC just to familiarise myself with using the scope in the field.

I've done some measurements in a taxi today, the whole white box of 18"UC can definitely fit inside the back seat but whether it can enter the door is another issue. The box can also go to the boot compartment but will stick out of the car by about 2 inches. Should be okay, but there is of course some chance of accident. In the worst case, we can just put the contents in the back seat, and the empty white box can go into the boot. After arriving at water mouth, can put the stuffs back to the white box and then use a trolley to tranport it to observation site.

May be I'll try to take taxi with an empty box in the next few days and see how it goes.

Once I am confident about everything, all are welcome to come along to enjoy the sky with this scope.

I can never afford a 22" because it is just too big for me. I am sure that 18" is the largest one I will ever get. If I want 22", may be I'll just see when I will have a chance to see Chanlunlun's 24" or 30".

I will seriously consider bringing this thing to Taiwan or abroad. Helpers are definitely welcome!!!

I see...

Just a thought: may be you can try book a handicap taxi to go to east dam. Your scope should be able to fit in easily...

其實如果天氣許可，這個週未就可以出動了！因為已經是廿二了。

The 5-year old 18"UC just had its first light after adding Argo Navis and ServoCAT system.

Good ar.


我估應該有用黎睇彗星，想知效果如何？例如細節。

It wasn't much different from what people having watched with big scopes here have said before - a rather bright nucleus with a halo.

On the more practical side, the students found it much easier to watch the comet at higher magnification as the nucleus was actually quite bright and was useful for focusing purpose. At low magnification, they didn't know how to focus.

Argo Navis and ServoCAT system - a must have for such a big Dob to locate object and keep it in the FOV...

Obsession 12 吋 仲輕過 Meade LightBridge 8 吋.




有無人可以講解係咩原因?

爲咗方便大量生產，Meade嘅筒係用 rolled steel，Obession 嘅筒，用木材。
