AI 猜 1500~2000  最後 pre order 2200,  正式 2990 .
 2990阿  比 2000 貴不少

Although I’m not super interested, it will give people pause that see results from the sho model, would be too late at that point….but probably the main thing people need to understand, a photo taken in show will take three times the data… ie 1 hour regular Draco… 3 hours sho Draco… so of course the Draco image would look better, but if you did 20 minutes of each filter I suspect the regular would look better. We will see but thinking that is true… I have not ever done it though

The mono version wont go into the Draco. We should forget about a mono one

Sensor: OV50K40  ??
 OV50K40 is a 50‑megapixel (MP) image sensor that features a 1.2‑micron (µm) pixel in a 1/1.3‑inch optical format with high gain and correlated multiple

It's been discussed before, the OV50K40 is not the sensor as it's 4:3 not 16:9 as the dwarflab app's draco fov indicates.

Delivery of the Draco (in Europe) likely from 5th November 2026 -
Pricing approx £1600 for the non SHO and £1800 for the SHO version.

STD :U$2200    SHO : U$ 2500
 $2,999 MSRP and a $2,200 pre order price may be where we are headinh
 => 後 9/7 修 SDT 1299  / SHO 1499 U$
  2200 真太貴了 ,

 3 sensors inside
- Tele : 50 Mpix 1/1.3 inch = 1.2 um pixel size = OV50Q40
- Wide : 50 Mpix 1/1.55 inch = 1.0 um pixel size = OV50E40
- Guide : 4.09 Mpix 1/3 inch (no specification) => OS04C1B (monochrome)
Binning 2x2 available on 3 sensors

But 1.2 um is really small... Bin 2x2 at 2.4 um in 12.5Mpx could be a compromise

zwo s30 s50 dual band filter
O III bw=30nm
H_alpha bw=20nm
 
Draco  O III /  Hα   13nm


拍 outer4 好像需窄 3nm , 用 7nm 也要很久 ..
Draco Hα：13 nm
常見入門窄帶：7–12 nm
比較進階：3–5 nm
極窄：1.5–3 nm

==

標準版：
Hα + OIII
   ↓
紅色      藍綠色
   ↓
一般雙窄帶星雲

它看到的是：

Hα：656.3/658 nm 附近
O III：500.7/503 nm 附近
所以像玫瑰星雲、北美洲、馬頭、心臟、靈魂、M42 等發射星雲，已經非常好用。

SHO 版：它會多拍一次：

第一次：Hα + OIII
第二次：SII + OIII
             ↓
       SII / Hα / OIII
             ↓
       Hubble Palette
             ↓
        藍 + 金色星雲

S II 的中心在 674 nm，頻寬也是 13 nm。Draco 會自動在兩組濾鏡之間切換，取得真正的 S II、Hα、O III 三個波段，再做分離、映射和合成。
 

所以 SHO 版最大的價值不是「更窄」  這點非常重要。SHO 版的 Hα 並沒有比較窄。

標準版 :  H + O
SHO 版 : S + H + O

這才是兩者真正的差別。 還有一個很容易忽略的差異：太陽
標準版把 OD5 ND 太陽濾鏡放在機內，所以可以直接透過 App 切換太陽模式。

SHO 版因為原本那個位置拿來放 S II + O III 濾鏡，所以改成附一個外接磁吸式 ND 太陽濾鏡。拍太陽時需要裝上它


我會這樣看：

主要拍星雲、想玩真正 Hubble Palette → SHO
主要拍星雲，但不在乎金藍色 SHO → 標準版其實就很夠
銀河、星團、星系也會拍 → 兩者都一樣，因為都有 Astro filter
常拍太陽 → 標準版方便很多，因為 ND 內建
想把 Draco 當成真正的自動化 SHO 星雲機 → SHO 才有意義
而且有個很有意思的地方：SHO 版拍攝時間/資料量會增加，因為它需要用兩組窄帶濾鏡取得 S/H/O 資料，而不是單純一次 Hα+OIII 就完成。官方就是設計成自動交替拍攝再合成

DRACO 是一台全自動智慧望遠鏡，

因此 13 nm 是一個比較「寬容」的設計。如果硬塞 3 nm 濾鏡，雖然背景會更乾淨，但進來的光也會少很多，曝光、追蹤、訊噪比和整個自動化流程都會變得更苛刻。而 DRACO 本身就是利用 2×2 binning，把 1.2 μm 像素合成約 2.4 μm 等效像素來增加低光表現


如果你是在桃園、新北、台北、台中、高雄等都市/郊區拍：

13 nm 的 O III 是比較吃虧的。
因為 O III 在約 500.7 nm，正好處在可見光背景比較麻煩的區域。

所以：

Hα 13 nm
→ 通常還可以
→ Hα 很強
→ 光害環境下仍然很好拍

O III 13 nm
→ 比較容易被天空背景污染
→ 月亮出來時尤其明顯
→ 背景容易變亮、灰、偏色

這也是為什麼進階玩家很常選： Hα 5 nm + O III 3 nm + S II 3/5 nm

我反而覺得 DRACO SHO 最大的價值是「方便


有很好的暗空地點   SHO 的價值更高。

因為天空背景比較乾淨，13 nm 的缺點會減少，而 S II 帶來的色彩/結構資訊就更容易發揮。

DWARFLAB DRACO – FOLLOW-ON FAQ / OFFICIAL CLARIFICATIONS - VOLUME #2
Thanks again to everyone who submitted follow-up questions after the initial DRACO FAQ.
I compiled many of the most common questions from the community and sent them directly to DWARFLAB for clarification.
Below is what they can currently confirm.

⚠️ IMPORTANT: Some technical details, operating limits and software functions are still being finalized. Where that applies, I’ve clearly noted it rather than filling in the blanks with assumptions.
━━━━━━━━━━━━━━━━━━
🔹 1. EQ MODE – WHEN IS IT NEEDED?
DRACO can normally operate in Alt-Az mode.
EQ Mode is available for users who want additional stability during longer exposures and multi-frame stacking.
You do not need a separate EQ mount or astrophotography wedge. The app will guide you through adjusting DRACO to the proper angle.
Still being finalized:
• Exposure threshold where EQ Mode becomes recommended
• Recommended targets/use cases
• Alignment tolerance requirements
For now, there is no reason to assume EQ Mode will be required for normal use.
━━━━━━━━━━━━━━━━━━
🔹 2. CAN I USE MY OWN TRIPOD?
Yes.
DRACO has:
• One 3/8-inch mounting thread
• Two 1/4-inch mounting threads
• Included tripod uses a 3/8"-16 connection
DRACO weighs approximately 5.5 kg, so any third-party tripod should provide stable support for that weight.
A separate wedge is not required for EQ Mode.
Still being finalized:
• Official minimum tripod load rating
• Recommended tripod/head combinations
━━━━━━━━━━━━━━━━━━
🔹 3. BATTERY LIFE / EXTERNAL POWER
DRACO includes a built-in:
🔋 77 Wh / 10,000 mAh / 7.7 V battery
Current estimate:
➡️ Approximately 5 hours in Astronomy Mode
The active cooling system currently has a relatively small impact on battery consumption.
DRACO can also operate while connected to external USB-C power, allowing you to continue imaging while supplying power.
Maximum charging power is 36 W.
Detailed runtime testing is still being finalized for:
• 300-second exposures
• Dual-camera operation
• PhotonLink
• Very cold temperatures
• Different USB-C PD power profiles
━━━━━━━━━━━━━━━━━━
🔹 4. HOW DOES SENSOR COOLING WORK?
The telephoto CMOS sensor is actively cooled to reduce thermal noise.
Heat produced by the system is also used to help prevent dew formation on the optics.
Still being finalized:
• Maximum cooling below ambient temperature
• User-selectable temperature settings
• Cool-down / stabilization time
• Exact temperature-control behavior
━━━━━━━━━━━━━━━━━━
🔹 5. WHY ONLY 128 GB OF STORAGE?
DRACO includes 128 GB of internal storage.
Actual usable storage will be slightly less because part of the space is reserved for the system.
Deep-sky images using 2×2 binning are approximately:
📷 12 MP / 4096 × 3072
A single uncompressed 16-bit Bayer FITS frame is approximately:
➡️ 24 MiB / about 25 MB
So roughly:
➡️ 100 RAW frames = 2.4–2.5 GB
That does not include thumbnails, metadata, stacked outputs or other processed files.
JPG, PNG and TIFF sizes will vary.
⚠️ External SSDs and USB flash drives are not supported as direct acquisition storage.
File management will generally follow the same workflow as existing DWARF products.
━━━━━━━━━━━━━━━━━━
🔹 6. HOW DO I DOWNLOAD RAW / FITS FILES?
JPG and other Gallery results can be viewed and downloaded through the app.
Original files such as:
• Individual RAW/FITS frames
• Stacked FITS/TIFF files
• Complete shooting folders
can be accessed through a computer connection, similar to DWARF 3 and DWARF Mini.
The exact app download/export options for each file type will be documented in the DRACO User Guide.
━━━━━━━━━━━━━━━━━━
🔹 7. WILL DRACO FITS FILES WORK WITH SIRIL, PIXINSIGHT, DSS, ETC.?
Yes.
DRACO FITS files will follow the same general external-processing workflow as current DWARF products.
They can be used with software including:
• Siril
• PixInsight
• AstroPixelProcessor
• DeepSkyStacker
The telephoto sensor uses a BGGR Bayer pattern.
Relevant metadata will be stored with the files so third-party software can properly debayer and process the data.
More detailed file documentation will come later.
━━━━━━━━━━━━━━━━━━
🔹 8. HOW DOES THE SHO EDITION WORK?
With the SHO Edition, filter selection and data collection are automated.
DRACO automatically uses:
• Hα + O III
• S II + O III
to collect the required datasets.
The system then separates and combines the:
• S
• H
• O
information automatically.
Current published bandwidth is approximately 13 nm per channel.
Still being finalized:
• Manual filter controls
• Individual channel export
• Recommended gain settings
• Recommended exposure settings
━━━━━━━━━━━━━━━━━━
🔹 9. IF STELLAR STUDIO CAN MAKE A HUBBLE PALETTE, WHY BUY THE SHO EDITION?
This is an important distinction.
The SHO Edition physically captures real S II, Hα and O III filtered data.
Stellar Studio can also use Hα and O III data to create an SHO-style / Hubble Palette color mapping.
Those are not the same thing.
Stellar Studio is remapping available channel data into an SHO-style color palette.
The SHO Edition actually captures real S II data through the dedicated S II + O III filter.
Still being finalized:
• Channel-mapping controls
• Strength adjustments
• Individual-channel export options
━━━━━━━━━━━━━━━━━━
🔹 10. HOW DO CALIBRATION FRAMES WORK?
DRACO automatically captures Dark frames in real time and applies:
• Dark calibration during Live Stacking (Telephoto)
The built-in Dark mechanism applies to the telephoto camera, similar to how the MINI functions.

Dark temperature matching, creating dark profiles or calibration management will generally follow the same mechanism used by previous DWARF products.
A quick clarification regarding Telephoto and Wide-Angle Darks on DRACO:

Telephoto---
For the Standard Edition:
• Telephoto uses internal DARK filter, similar to Mini process
*no need to use any external filter*

For the SHO Edition:
• Telephoto uses internal DARK filter, similar to Mini process
*no need to use any external filter*

Wide-Angle---
For **BOTH** Standard and SHO Edition:
• Wide-Angle uses internal ND Filter (ND: OD 5 @ 400 ~ 1000 nm)
• The arm will be rotated down and closed, blocking any additional light.
• Wide-angle Dark frames can then be captured.

Manual Dark Library management options have not yet been published.
━━━━━━━━━━━━━━━━━━
🔹 11. HOW DOES GUIDING WORK WITH 300-SECOND EXPOSURES?
DRACO includes integrated guiding and supports individual exposures of up to:
⏱️ 300 seconds
Guiding is handled automatically during the normal imaging workflow.
Pro Mode allows control over settings including:
• Exposure
• Gain
• Filters
• Other imaging settings
Still being finalized/documented:
• Guiding graphs
• Manual guiding parameters
• Guide-star failure behavior
• Exact relationship between 300-second exposures and EQ Mode
━━━━━━━━━━━━━━━━━━
🔹 12. HOW DOES FIELD DEROTATION WORK?
DRACO includes physical field derotation with approximately:
➡️ ±90° of mechanical travel
Still being finalized:
• Long continuous-session behavior
• Automatic reset behavior
• Interaction between derotation and EQ Mode
━━━━━━━━━━━━━━━━━━
🔹 13. WHAT IS DRACO'S LIMITING MAGNITUDE?
DWARFLAB has not published an official limiting-magnitude value yet.
Actual performance will depend on:
• Sky quality
• Seeing
• Target type
• Exposure length
• Total integration time
• Stacking quality
DWARFLAB plans to share more real-world examples involving:
• Faint galaxies
• Planetary nebulae
• Comets
• Asteroids
as testing continues.
━━━━━━━━━━━━━━━━━━
🔹 14. WHAT DAYTIME / TERRESTRIAL FEATURES ARE INCLUDED?
DRACO supports:
📷 Photo
🎥 Video
🌄 Panorama
⚡ Burst
⏱️ Time-lapse
with both the telephoto and wide-angle cameras.

Astronomy modes include:
🌌 Deep Sky
🌌 Milky Way
⭐ Star Trails
☀️ Solar
🌙 Lunar

Dedicated bird, wildlife and general-object tracking features have not yet been confirmed.
━━━━━━━━━━━━━━━━━━
🔹 15. ETHERNET / USB / NETWORK CONNECTIVITY
DRACO supports:
• USB 3.0
• Wired Ethernet connectivity through USB
This is intended to provide a more stable network connection and more efficient data transfer, especially for longer or remote imaging sessions.

Example USB-C/Ethernet Dongle: https://www.belkin.com/....../usb-c-to....../INC019btBK.html

**self purchase** - DWARFLAB has not confirmed yet if they will offer it as an accessory purchase
Final documentation will explain:
• Local Ethernet control
• Router configuration
• Network file access
━━━━━━━━━━━━━━━━━━
🔹 16. PHOTONLINK / PHOTONVERSE REMOTE CONTROL
PhotonLink allows DRACO to be remotely controlled through the DWARFLAB app.
The owner will also be able to invite other users to participate in remote operation.
Still being finalized:
• Account requirements
• Invitation method
• Simultaneous viewer limits
• Control permissions
• Revoking access
• Connection-loss behavior
• What DRACO does if the network connection drops
These details will be covered in the User Guide.

━━━━━━━━━━━━━━━━━━
📌 FINAL NOTE
These answers came directly from DWARFLAB in response to the follow-up questions submitted from the community.
There are still some specifications and software behaviors being tested, documented or finalized.
If something above says “still being finalized,” that simply means there is not a definitive answer available yet.
As more information becomes available, we can continue updating the FAQ instead of filling the gaps with rumors, assumptions or speculation.
Hopefully this clears up a good portion of the recurring DRACO questions we’ve been seeing
