In AZ Mode:

  Save a Terrestrial User Object with Axis1=0, Axis2=0  (this represents North/Level)

  Slew (Goto) this saved position, with tight clutches.  Your encoders are now at (0, 0) North/Level

  Loosen both clutches and move your MOUNT so that your OPTICS are pointing North/Level.  Re-tighten your clutches.  Now your mount and encoders are in sync.

    Be mindful of your dovetail orientation, specifically if using an L-Bracket, or any other right-angle type of mounting to your optics, as this might change the direction your optics are pointing relative to the direction the mount is pointing.  (your optics may be parallel, or perpendicular to the mounts dovetail)  (scopes are often parallel, DSLR's are often perpendicular).

 

In EQ Mode:

  Save a Terrestrial User Object with Axis1= -90, Axis2= 90 (this represents EQ Home)

  Slew (Goto) this saved position, with tight clutches.

  Loosen both clutches and move your MOUNT so that your OPTICS are pointing at the NCP (near Polaris).  Re-tighten your clutches.

 
 

信達的 azGTi MOUNT   開箱

手機 WIFI 得先選到  synScan or Pro  連上是  altaz mode  .  目前還不知道 如何切到EQ MODE
 下面數字是速度 可以  左右調,  9 是最快速 .

Pro  在ALIGN 上多了一些 ,   還有些PEC   應該是給信達赤到儀用連POLAR SCOPE 燈都能控制 .

 This application is used to update the motor controller's firmware of a Skywatcher telescope mount, which has a build-in Wi-Fi module or an external SynScan Wi-Fi dongle.
1. Disconnect the ethernet cable from your PC.
2. Let you PC join the Wi-Fi network provided by the mount's build-in Wi-Fi or an external SynScan Wi-Fi dongle.
3. Run MCFirmwareLoader_WiFi.exe
4. Use the "Browse" button to load the new firmware file (*.MCF) for the mount's motor controller.
5. Click "MC Version" button to check the version of the motor controller; or,
   click the "Update" button to load the new firmware to the motor controller.
6. Re-try if the updating fails.

原來得刷 az_eq 那個MCF  FILE
 
1.  motor_controller_fimrware_loader_-_wifi_version_174.zip
2. select MCF  FILE 
  => azgti_motor_controller_firmware_rightarm_0320.zip

3.  要先問馬達版本  

 但一開始 NOTEBOOK  用WIFI  連有連上  , 看MC  VERSION  說認不得..結果突然  AZGTI 認不到  只看 wifi 上有  synScan  .. 手機一直連說沒有  NP DEVICE  .. 以為要返廠
  才剛拿到阿 ..

後來看  MCF  WIFI 更新說要TRY  就算FAIL .  還是要 TRY UPDATE ..
再用 NOTEBOOK  在連 ..在問VERSION ,    一樣說不知道 版本  但READY  ,   就UPDATE   反正死馬當活馬.. 突發現 電腦開始 UPDATE MCU ,   更新算快 . 一下完後, 說重開 AZGTI  ,  
手機重連  , 重新看到AZGI  那WIFI  NAME   synscan_xxxx 感覺可能會回來,  一連上果然出現  AZ  跟EQ  兩個 MODE ..

真的好險阿。

這邊右邊圖跟左邊不同?

  不知道那個是對 ??

設計 有問題  ,   台灣角度無法 對 ,  我有 sky tracker pro .. 可以用這微調
但是 AZGTI  極望向不同 , 高緯度可 ,  但是 , 台灣 23度無法 使用   會卡到  ,

兩邊都調過全都會卡到.  

star Party 對過  比POLARIS 角度高太多 . 今天又測一次 , 果然設計 不能給台灣用 ,

GRUS  回信

看來是  90-60  = 30 度

緯度30 度以下無法使用

CUBE PRO  WEDGE 是M8 

SA  的底不知道 角度能多大?? 

cube pro wedge  可用  剛好 M8  可拆下換 3/8  螺絲

但是 ..  會卡極望   轉動 要小心 .. 這設計不好 應該離更遠些吧
 另外  下面左右微調也會被本體卡到  很難調 . 

今天發生  GOTO 方向跑錯邊.  1 star align  SIRIUS   仰角類似 差不多 但左右顛倒?   明明SIRIUS  東邊剛起來 ,  卻跑去指向西邊
  APP 看UTC  時間跟台灣  差 8HR  也對阿 .   難到裝反? 



感覺 AZGTI   也沒地方數經偉度難到知道 手機上資料 ?
 

不過 單看EQ MODE  TRACKING
 500d (apsc) +   135MM  ISO=100  單張 118 sec  and  58sec  參宿4  跟  Sirius   ZOOM IN
 感覺  60SEC 可以 , 但 2MIN 會小拖,  沒上重鎚.. 外掛極軸位置不好抓  .

 AZ-GTi Alignment Instructions



https://www.cloudynights.com/topic/658474-skywatcher-synscanaz-gti-alignment-instructions/


 Posted 20 April 2019 - 01:15 AM

The following information is not official nor authoritarian, it is simply my conclusions from thoughtful testing and careful observation.  All described behaviors are based upon insight and conclusion, not upon actual knowledge of the Synscan code.  In other words, my best guess cool.gif

 

Synscan Pro for iOS, ver 1.16.1 seems to have an incomplete Reset Alignment bug whereby the current sky model is not removed from memory.  I have reported this bug to Skywatcher.  Hopefully they will investigate and resolve.

 

Synscan Pro for Windows PC, ver 1.16.0 is correctly removing the sky model from memory when you Reset Alignment.

 

Power on Mount
Axis will be reset to the default position.

 

Synscan Connect
AZ Mode:  The Axis default position will be (0, 0)
EQ Mode:  The Axis default position will be (-90, 90)
Az/Alt will be set to the Axis plus offset of the current sky model.  The offset will be (0, 0) if no sky model exists resulting in an Az/Alt of (0,0) for AZ Mode, or (0, Your Latitude) for EQ Mode.

For Synscan Pro for iOS ver 1.16.1
Synscan will remember the previous sky model and offsets, unless you do the following, in order:
    1. Reset Alignment
    2. Remove Synscan from device memory
If a sky model is present, stars will be listed in Align with Sync

Reset Alignment will sync Az/Alt to Axis in AZ Mode, and Az/Alt to Axis plus Your Latitude in EQ Mode.

Reset Alignment ALONE, DOES NOT remove the sky model, you must also close Synscan, remove it from device memory, and re-launch. (No need to power off/on the mount, or disconnect wireless)(This is an APP ONLY operation to remove the sky model from memory).  Close and re-open is not enough, you must remove the app from background memory.

 

Best Practice:
Always remove the Synscan APP from device memory after Reset Alignment, and then re-open and re-Connect the APP to the mount.

 

Synscan Pro for Windows PC ver 1.16.0 will still retain a sky model if exited and re-launched, as it should. It also correctly removes the sky model when you Reset Alignment.

 

Alignments
Any type of Alignment will add to an existing sky model, or create one if one does not already exist.
Confirming center of any object will add error correction offsets to the current sky model.  These offsets will correct for slight in-accuracies in geographical location/time and mount leveling.  They won’t compensate for any variations in the gravitational constant in your backyard.    The point here is, that the sky model/error offsets can get wonky if your adding new data to an old existing sky model.

 

1-Star Alignment
The mount will slew to the selected star coordinates from current Synscan Az/Alt.  The accuracy is entirely dependent upon the current Synscan Az/Alt being real-world-correct and the accuracy of the mounts level.
Confirming center will sync the Az/Alt to the star coordinates, add the star to Align with Sync, and create the sky model.  The accuracy of the sky model will be based on just the offsets created by the centering action of one star.

 

 

Brightest Star Alignment
Manually center the 1st star. The mount will NOT MOVE to the 1st star, you are expected to slew or move the mount to the 1st star yourself.  This requires you to be able to look up and identify the 1st star yourself.
Confirming center will sync the Az/Alt to the 1st star coordinates.
The mount will then slew to the 2nd star coordinates from the current Az/Alt.  Accuracy will be dependent upon the mounts level and how accurate you centered the 1st star.
Confirming center will sync Az/Alt to the 2nd star coordinates, add the stars to Align with Sync, and create the sky model.  The accuracy of the sky model will be based on the offsets created by the centering action of the two stars, and the error calculated between the 2 stars (linear).  The offsets compensate for level inaccuracies, and will be applied to subsequent Gotos.

 

North-Level Alignment (AZ Mode Only)
This alignment is similar to a Brightest Star Alignment, except you don’t need to be able to identify stars, you just need to know which way is North.
Set the scope/mount pointing north and level.  Bubble level and smart phone compass, and even best eyeball guess is accurate enough in most cases.
Confirming north and level will sync Az/Alt to 0, 0.
The mount will then slew to the 1st star coordinates from the current Az/Alt.  Accuracy will be dependent upon the accuracy of the north and level placement.
Confirming center will sync Az/Alt to the 1st star coordinates.
The mount will then slew to the 2nd star coordinates from the current Az/Alt.  Accuracy will be dependent upon the mounts level and how accurate you centered the 1st star.
Confirming center will sync Az/Alt to the 2nd star coordinates, add the stars to Align with Sync, and create the sky model.  The accuracy of the sky model will be based on the offsets created by the centering action of the two stars, and the error calculated between the 2 stars (linear).  The offsets compensate for level inaccuracies, and will be applied to subsequent Gotos.

 

2-Star Alignment (EQ Mode Only)
The mount will slew to the 1st star coordinates from the current Synscan Az/Alt.  The accuracy is entirely dependent upon the current Synscan Az/Alt being real-world-correct and the accuracy of the mounts level.
Confirming center will sync Az/Alt to the 1st star coordinates.
The mount will then slew to the 2nd star coordinates from the current Az/Alt.  Accuracy will be dependent upon the mounts level and how accurate you centered the 1st star
Confirming center will sync Az/Alt to the 2nd star coordinates, add the stars to Align with Sync, and create the sky model.  The accuracy of the sky model will be based on the offsets created by the centering action of the two stars, and the error calculated between the 2 stars (linear).  The offsets compensate for level inaccuracies, and will be applied to subsequent Gotos.

 

3-Star Alignment
This is the most accurate alignment because error offsets can be triangulated instead of calculated linearly.
The mount will slew to the 1st star coordinates from the current Synscan Az/Alt.  The accuracy is entirely dependent upon the current Synscan Az/Alt being real-world-correct and the accuracy of the mounts level.
Confirming center will sync Az/Alt to the 1st star coordinates.
The mount will then slew to the 2nd star coordinates from the current Az/Alt.  Accuracy will be dependent upon the mounts level and how accurate you centered the 1st star
Confirming center will sync Az/Alt to the 2nd star coordinates.
The mount will then slew to the 3rd star coordinates from the current Az/Alt.  Accuracy will be dependent upon the mounts level and how accurate you centered the 2nd star.
Confirming center will sync Az/Alt to the 3rd star coordinates, add the stars to Align with Sync, and create the sky model.  The accuracy of the sky model will be based on the offsets created by the centering action of the three stars, and the error calculated between the 3 stars (triangular).  The offsets compensate for level inaccuracies and will be applied to subsequent Gotos.

 

Polar Alignment (EQ Mode Only)
Polar alignment in Synscan requires that you first perform a Bright, 2, or 3 star alignment.  I recommend 3 star for greatest accuracy.
The mount will slew to the chosen star for Polar Alignment.
Confirming center will sync Az/Alt and use the offsets plus current sky model to calculate latitude and altitude base adjustments.  Synscan will move the mount accordingly and ask you to center the star using the base latitude adjustment.  Center the star as close as you can using just the one base adjustment.  Synscan will move again and ask you to center the star using the base altitude adjustment.  Center the star as close as you can using just the one base adjustment.
Since you have “pulled the rug out from under” the current sky model by adjusting the base, you will need to Reset Alignment, and perform a new Star Alignment.

 

Synscan Pro for iOS ver 1.16.1 will require that you remove Synscan from memory after Reset Alignment, re-launch Synscan, re-connect in EQ Mode, and perform the Star Alignment of your choice.

 

The accuracy of the Polar Alignment will generally be good enough for visual, un-guided short exposure imaging, and long exposure guiding.  You can perform another iteration of PA/SA to achieve greater accuracy.

 

Tracking
In EQ Mode, tracking is easily accomplished by setting the RA(Azimuth) gear rate of rotation to sidereal.  This rate is constant.  Accuracy is primarily dependent upon the precision of gear and motor manufacturing.
In AZ Mode, the mount will use the current date/time/location and the object coordinates to calculate the proper gear rate of rotation for both axis.  These rates are variable depending on the position in the sky of the object.  Eastern objects move up faster than they move right, Southern objects move right faster than they move up or down, Western objects move down faster than they move right.  Northern objects don’t go to market, stay home, or go wee wee wee.  If you’re in the Southern Hemisphere than Northern objects do, in fact, go wee wee wee.

 

 

Point-and-Track (AZ Mode Only)
Tracking does not require an alignment or a sky model.  Select the object from the appropriate list and choose Point-and-Track.
(For EQ Mode, just point the scope at the object and select the appropriate tracking rate from the tracking menu in the upper right corner of Synscan)

 

 

Point-and-Go
Synscan will use your mobile device’s accelerometer to slew the mount to the general area of the sky your device is pointing at.  You can then further refine the position by selecting an object from a nearby object list.  Point your device and press Point-and-Go from the Utility Menu.  You do not need to continue pointing while the mount slews.

 

Although I hope you find this information clear, concise, and useful, I hope even more that we all experience more Clear Skies!

AZ-GTi 經緯儀做 star alignment  的小技巧

要經緯儀能夠準確尋找及追蹤星體需要一些輔助的小工具

包括包括：
1. 平水尺
2. 水平調節底座
3. 磁力計
4. 指南針

AZ-GTi 經緯儀 (晚上可以看到北極星) 對準步驟

1. 打開三腳架
2. 安裝水平調節底座
3. 用平水尺協助，調整好水平調節底座，令底座處於水平狀態
4. 安裝 AZ-GTi 經緯儀
5. 不要開啟 AZ-GTi 經緯儀
6. 鬆開 AZ-GTi 經緯儀底座鎖緊用的鑼絲
7. 將望遠鏡安裝位置轉至觀測者右側
8. 安裝望遠鏡或相機
9. 將望遠鏡或相機指向北極星，直至北極星位於目鏡視場的中心
10. 用平水尺輔助將望鏡或相機放置在水平位置
11. 鎖緊 AZ-GTi 經緯儀的兩顆鑼絲
12. 啟動 AZ-GTi 經緯儀
13. 打開手機，將網絡連接到 AZ-GTi 網絡
14. 打開 SyscanPro 應用程序
15. 將 AZ-GTi 經緯儀連接到 Alt-Az 模式
16. 選擇調準 (Alignment) 方法
17. 選擇北極 - 水平調準 (North-Level Alignment)
18. 按照指示，使用亮星對齊校準，如果目標星星不是在目鏡視場的中央，用上、下、左、右鍵將目標星星移動至視場中心
19. 然後按順序選擇北極星作為下一個目標，重複上述第18 步驟

AZ-GTi 赤道儀模式
https://forum.hkas.org.hk/thread-10467-2-1.html
緯度調節器連極軸望遠鏡（注意：這個設計會阻礙望遠鏡在某些位置不能移動，使用前必須留意）



按照生產商的安裝方法，只能在緯度40度或者更高以上使用，是不適合香港的緯度使用。使用者需要倒轉安裝才可以在低至緯度21度使用。

使用 QHY Pole Master 電子極軸鏡頭只能當作不能跟隨赤經軸旋轉的極軸望遠鏡。不能使用 Pole Master 的軟件的調節功能。
使用 Pole Master 電子極軸鏡頭或者極軸望遠鏡對極之後，要拆除才可以避免望遠鏡在赤道儀模式運行時不會碰撞到

感謝曹兄  ..原來他也碰過跑錯方向 



後來每次開機（或回到零位）就會執行一次復位，
然後再打開輔助編碼器（不打開也可以）
甚至每次回到“零位”，我就會執行一次“復位”讓赤道儀知道已經到“”初始位置了”

信达赤道仪如何连接ASIAIR实现精准goto

http://zwoasi.com/photography-guidance/2876.html

ZEQ5, AZEQ6, AZ-GTI等，属于赤道/经纬混合式。所谓赤道/经纬混合式，就是可以通过设置模式来切换赤道仪模式和经纬仪模式。

ASIAIR可以支持这两种赤道仪，AZEQ类型的赤道仪需要在赤道式模式下才能与ASIAIR通信。

先通过SynScanAPP配置好WiFi，station模式下连接ASIAIR的热点，设置静态IP地址10.0.0.11。采用EQMOD协议通过端口11880 UDP方式连接。具体方法请参考另一篇文章：ASIAIR与信达AZ-GTI经纬仪搭配使用指南。

AZ-GTI星野赤道儀的回差調整
Luke 的休閒筆記

一、如何平衡 SkyWatcher AZ-GTi
所需要的工具：水準儀
所需要的改造：RA 軸心處的吊環
AZ-GTi 的結構簡單，並不是設計用來載重的極小型赤道儀，它原先的設計就是用來做為可以自動導入的經緯儀使用的，因為是雙軸導入的設計，所以 SkyWatcher 後來把這個架台修正韌體，並有警語說不是為了天文攝影目的設計的架台，若拍攝的結果未能如預期也不要怪他們，不過很多人都這樣做了。
AZ-GTi 的 RA 軸心很短，這也意謂著軸心容易歪斜，除了把機子拆開，將 RA 軸心的固定螺絲鎖得更緊之外，別無他法。隨著 RA 軸心固定螺絲的迫緊，RA 軸與大齒盤之間的磨擦力會增加，讓 RA 軸變得很不容易轉動，也讓離合器的功能失效，這時 RA 軸的平衡就會非常難做 (RA 軸變得很緊不易用手轉動的現象，與 RA 軸在追蹤時會不會很緊轉不動無關，在離合器緊咬大齒盤時同時也會將轉動的滑順度交給軸心上的培林，如果你把蝸桿的卡位制動力去除，就會知道我在說什麼)。
AZ-GTi 的 Dec 軸很好平衡，但也不是裝上去才做平衡，它能裝上的器材通常不重，可先把裝在鳩尾板上的整套器材倒著拿，鳩尾板在上，水準儀放在鳩尾板上，用拿著鳩尾板的手在鳩尾板上移動，找到能讓水準儀水平泡準心的位置，這個位置就是在夾在 Dec 軸心上的位置。
RA 軸完全不能在安裝後求得平衡，所以我做了一些改造，在 RA 軸的低仰度用的鳩尾套件上，裝上一個吊環，吊環的位置是 RA 的軸心延伸。在 AZ-GTi 沒有裝任何器材時，拉著吊環就會發現它已有一定的自重平衡狀態，這是非常貼心的設計。在 Dec 裝上器材，並有平衡重錘之後，將吊環拉起，把水準儀放在 RA 軸背上，並與 Dec 的軸心重合，再來調整重錘的位置，直到水準儀水平泡準心為止，這就是重錘所要在的位置。
接下來就可以將 RA 的鳩尾套件，安裝到極軸調整器上。
二、校極與自動導入
我用的極軸調整器是「奇峰精工」黑糖哥哥出品的神器，利用 AstroMuch 的對極功能，很快就能找到很小誤差的極軸精度，第一次自動導入到 M31 就在畫面中，拍攝解星後，之後導入其他目標就相當準確。AZ-GTi 的周解析分點是 2304000，是 AZ-EQ6 的 1/4 精度，為 0.5625” 的角解析度，在這麼小的赤道儀上已是相當準確的設計。
三、追蹤與導星精度
追蹤與導星的精度得看視凝度與大氣濛差的影響，我認為 AZ-GTi 的導星的準度不太可能低於角解析度。AZ-GTi 的角解析度是 0.5625”，所以 RA 軸導得再準，應不至低於這個數値，Dec 的話要看極軸的準度與視凝度，但基本上也不會低於角解析度。這幾天的天氣狀況很不好，在璨樹颱風來前我測到的導星狀況是 RA RMS 為 1”，Dec RMS 為 0.7”，算是很合理的數値。
四、好不好用
好不好用看個人，不帶風向，只有自己去媒合器材與預測極限而不要超過，許多赤道儀都會提供角解析度的數値，儘量用這個數値去配合你的導星設定，最小不動閥値要設的比角解析度高一點 (要注意角秒與像素的單位，並以赤道為基準，以我用 Kowa 100 為例，AM 的 CMOS 1.55µm/px，pxfov 為 3.2"/px，0.5625" 佔約 1/5 px，在 PHD2 上設 0.2，AM 自抓為 0.8" 為 0.25 等，PHD2 最小値就是 0.2，設更低也內部也會改回 0.2，AM 不讓你設，由導星品質決定，最小在 0.25 左右)，再配合 aggressive 去調整，或許會省不少的問題。

對這台比較好奇

台灣不知道有沒有人用

https://www.skywatcher.com/product/star-adventurer-gti/ (https://www.skywatcher.com/product/star-adventurer-gti/)

SA GTI 就  攝星 帶 GOTO  , 類似 還有 ioptron smartEQ pro .  應該 是可以用 ,
 因為 只多 goto , 國外 azGti  用很多

SA GTI  FB

台灣 就不知道 誰有買

AZ-GTi 和 StarAdventurer GTi 兩種我個人都有,
是很方便的 Grab-n-Go mounts.
5公斤的載重, 對 7公分以下的望遠鏡很夠用.

哪能否 分享下   StarAdventurer GTi  使用心得   . 

thank you .

簡單分享一下使用心得,

Star Adventurer GTi 是我個人認為功能最為完整的一支 star tracker,
因為我用過 Vixen Polarie, AstroTrack TT320X-AG, Star Adventurer 2i, 其中  AstroTrack TT320X-AG 是我用得比較多的,
雖然我不常使用這些攝星儀, 但我認為這些都是好儀器, 都能滿足廣視野的星空攝影, 也可以拍出好照片,
但是這些儀器, 就是少了 GoTo 的功能, 所以想要拍長焦 (>200mm) 一點點 的星空, 就比較辛苦, 必須 trial-n-error 好多次才能確認構圖,
SA GTi 補足了這個缺憾, 讓找目標這件事變得容易許多.  原廠設定他必須使用 SynScan App 去控制, 這個使用經驗很不好, 如果是電腦版的, 常常當掉, 後來我幾乎不用 SynScan App, 都用 USB + EQMOD + NINA, 很穩定.

原廠重錘是 2.25 kg  (5 lb)的, 用在我的設備上, 太大顆了, 我去網上買了 iOptron 1.5 kg 的, 完美組合!


買這種中國製的產品, 就要有品管不良或設計,製造不佳的心理準備, 我的這部 SA GTi, 有兩個問題:
1. Polar scope 的保護罩很容易輕輕一碰就脫落, 滿地彈跳. 如過裝了電池後, 根本就蓋不回去了, 因為電池座跟 極望保護罩產生干涉, 這是設計問題
2. RA 轉動到某個角度時, 內部會發出嘎嘎的摩擦聲, 我拆開後發現是內部束線帶磨到周邊, 調整一下束線帶的位置, 這個小問題就沒有了.

另外, 應該是因為bearing 用得不夠多的關係, 兩軸轉起來都比較澀, 所以平衡要多花點心思和時間.
那個固定 RA 軸的旋鈕感覺很弱, 不要太用力轉很緊.

除了上述以外, 使用起來還算順手, 因為我是在澳洲買來在市區使用的, polar scope 根本派不上用場, 所以不確定 polar scope 用起來是什麼感覺, 但是他改善了 SA 2i 的問題, 明視野照明是內建的, 不需要再罩上那個很討厭又很容易弄不見的裝置了.

GoTo 的速度算很快, 應該至少有 700X, 聲音很吵, 所以你不用擔心不知道他到底有沒有在動 (我都在屋子裏面操作的).

因為用 NINA 的關係, plate solving 可以幫你轉到你想要拍的星野去,
我用 NINA 的 Three-point-polar-alignment, 極軸可以對得相當準, 但是需要有耐心和執著的意志,
沒有導星, 300mm 至少可以拍到 120 sec 星點看起來還算圓.

簡單來說, 這是我喜歡用的一部儀器, 輕便沒有負擔, 足以勝任用單眼相機進行廣視野星空的拍攝任務.

.

還有另一台  ioptron smart EQ pro 中國那叫  沙馬特  也 是攝星 + GOTO  不過極望不好 .. 還有 payload 不夠高.   SA GTI 就好多

有 GOTO 打彗星很方便拉 . 先前打彗星 align ok .  金星 看到  就 直接 GOTO 彗星 ..等天暗 就開拍 .
