我都有興趣
只是連入場費都付不起:(
除非有極多人合資啦

當係天文年自發活動也不錯...

錢唔係最重要,反而係有冇興趣一起做,
我覺得幾個人能合作,將自己的強項提供一下,
懂得電腦和電腦打交道的,
有時間的提供時間,
有地方的提供地方,
其餘的,可以按當時的條件而作。

目前可以作的,是在室內完成一套利用電腦遙控的初版,
當中可能要有人提供chips或電路開關。牛人如高興或鏡神,唔知
有冇些現成的,你知有過來人指路,會事半功倍。

Dear Mr. BingSze,

Yes.

It happens that we just have one. This is a RCOS 16 inch RC telescope riding on a Paramount. It is robotic ready.

We have been testing it nearly every night since August and it is running stable so far.

Please take a look at attached picture. This telescope is scheduled to be installed onto our roof inside an observatory dome upon January 2009. This will be a totally robotic telescope inside a totally robotic dome, if everything runs according to our plan

Best regards
Chan Yuk Lun

Wow what a beast!

I'm most interested to know what's the mount controlling software (the Sky6?) in particular any difficulties in between sessions when you have parked the scope last night and now need to acquire a new target.

For any remote observatory, I guess the mount has to be very accurate like Paramount / Takahashi EMs otherwise there might be a need to provide a second wide field CCD just in case the mount misses the target, then you still have a clue of which part of the sky you're generally pointing to. You know the imaging CCD field of view is usually very small.

Sorry for being long winded - is the current remote control set up uilizing a scheme like "PC Anywhere" or is included in the proprietary software so that you can access from anywhere?

Many thanks.

會唔會用 "DSLR + USB線" 可以代替一個貴價天文CCD, 而且面積大好多好多!

Yes that's what I'm thinking about too. But I just can't figure out how to remotely turn on/off a DSLR or any CCDs, dew heaters etc...probably there exists some on/off switches that is controllable by computer.

For canon DSLR, (the power switch is at "ON" position) it will be turned on when power is from off to on, just like changing battery.

The camera should also have to shutdown the sleep-mode function.

鏡神,多謝你的提供,
我的想法就是和你相中的儀器差不多,當然,不是用
這樣的鏡和赤度儀啦!
但如果我們可以照樣在水口或其他地方試試,之後再安鏡和建dome,
這樣,我們就有多一個地方睇星和拍野了,

你有冇收版權費呀?貴唔貴架?
唔知一餐晚餐得唔得呢? :wink:

可能佢收你每次觀測一餐晚餐, 兼且佢每次搬 30" 鏡時, 你要在場幫手! 8) 8) 8)

有支三十吋口徑的望遠鏡可以睇,嘻!每次幫手都冇所謂啦。

Dear Mr. 45,

The Paramount is now being controlled by TheSky Version 5, under Window XP O/S. Originally TheSky 5 cannot run under XP but we have downloaded the upgrades from Software Bisque and this enables the software being capable of operating smoothly even under the XP.

The robotic part is a direct application of Windows Remote XP, included inside the Window XP Professional O/S.

At the momenmt we still have no idea of the pointing accuracy of the Paramount. The wholesetup is being tested indoors. For star trails I'm sfraid that we have to wait until Jan 2009.

The whole system is still under devlopment. What you have seen in the attached picure is just part of the whole scenario. Many items are waited to be added - a remote telesocpe cover, a remote control flip mirror system, CCD camera, software developed for remote power control, remote lamp, survellence camera, weather station to automatically shut down the observtory in case of sudden rainfall, parallel port interface ........just to mention a few.

We are now discovering that a robotic observatory is not as simple as we what we first thought of. It is not just plugging a wire into the LAN socket......way far from it.

Best regards
Chan Yuk Lun

Dear Chan Sir,

Thanks very much for your info. This is no simple work really! I guess I'm at the level of fully computer controlling the scope at the spot, i.e. GOTO, focusing, image acquisition etc. without touching the scope. Next step is to put the setup inside an openable shelter and then operating it remotely.

Best regards.

Typical setup should be using Remote Desktop through VPN.
