剛星期五晚的七月觀星實習期間天公造美，活動開始後一個小時雲層散去，滿天繁星一直到第二環節調校望遠鏡完畢即凌晨2點我們離去時。8小時間收穫甚豐，超過過往任何一次實習，大家都滿載而歸 https://eshop.astro.hk/hk/catalogs/products/2caf077a-fc34-4c25-a6af-aebd212a2f04

因為活動取決於天氣，我們通常於週日或週一才發佈訊息及公告，並於緊接的週五或週六晚舉行，雖然通知時間很短，但感謝各會友支持，活動往往於短時間內滿額。有興趣日後第一時間收到活動及器材訊息的朋友，可whatsapp至星河科研社98119630並註明”訂閱”或”Subcribe”，便可以每月收到一兩次相關訊息。

當晚出動器材，

• Celestron EdgeHD 14、RASA 11、Nexstar 8SE、6SE、Starsense Explorer LT80 AZ望遠鏡
• Software Bisque Paramount MyT 赤道儀
• ZWO AM5赤道儀
• Askar 65PHQ攝星鏡、Sky-Watcher Star Adventurer GTI 赤道儀
• ZWO 2600MC、533MC、QHY600 Pro相機
• Starizona Hyperstar 8、14攝星系統
• Antlia RGB Ultra、IDAS LPS-D3濾鏡

當晚和會友進行了的實習，

• Celestron NexStar 三星校正
• Celestron Starsense Explorer手機輔助尋星
• 手機拍攝金星
• 快速校正極軸、ASIAIR自動對焦、解析、導星及實時疊加等，並拍攝了多個深空天體，包括M7、M8、M13、M20、M27、M57等。

活動後工作人員留後調校好Celestron RASA 11的焦平面、V  curve及Software Bisque Paramount MyT赤道儀 的PEC曲線，以趕及月底發送至海外建立新一個遙控觀測站，當晚視寧度不錯，這系統在3.76微米相機像素下，仍可以保持焦點全天指向穏定，全片幅下整個像場維持2.0至2.5像素即1.25” FWHM 1.25的成像度。

During the stargazing workshop on Friday night in July, the weather was perfect. An hour after the start of the event, the clouds disappeared and the sky was filled with stars until we finished tuning the telescope in the second session at 2am when we left. We had a very fruitful 8-hour session, surpassing any previous workshops. Everyone had a very fruitful night https://eshop.astro.hk/hk/catalogs/products/2caf077a-fc34-4c25-a6af-aebd212a2f04

Since the event is weather-dependent, we usually only announce the event on Sunday or Monday and hold it on the following Friday or Saturday night. Although the notice is short, we thank our friends for their support and the event is often fully booked in a short time. For friends who are interested in receiving real time event and equipment information in the future, they can WhatsApp to Galaxy Scientific Group at 98119630 and indicate "subscribe", and they will receive relevant messages once or twice a month.

The equipment used that night included, 

• Celestron EdgeHD 14, RASA 11, Nexstar 8SE, 6SE, Starsense Explorer LT80 AZ telescopes, 
• Software Bisque Paramount MyT equatorial mount, ZWO AM5 equatorial mount, 
• Askar 65PHQ astrograph, Sky-Watcher Star Adventurer GTI equatorial mount, 
• ZWO 2600MC, 533MC, QHY600 Pro cameras, 
• Starizona Hyperstar 8, 14 astrograph systems, 
• Antlia RGB Ultra, IDAS LPS-D3 filters.

During the workshop we conducted, 

• Celestron NexStar three-star alignment  
• Celestron Starsense Explorer smartphone app enabled observing
• Captured images of Venus using a smartphone
• Quick polar alignment, ASIAIR automatic focusing, plate solve, auto guiding and real-time stacking, and captured several deep sky objects, including M7, M8, M13, M20, M27, and M57.

After the workshop, we staffs stayed behind to tune up the Celestron RASA 11's focal plane, V-curve, and Software Bisque Paramount MyT equatorial mount's PEC curve, in order to send it oversea to establish a new remote observation station by the end of the month. Seeing that night were good, and the system maintained stable focus throughout the different parts of sky, and maintained  2.0 to 2.5 pixels or 1.25” FWHM across the field of the full frame camera of 3.76um pixels.
