We are pleased to announce the launch of the new version Oasis Focuser – the Oasis Focuser Rose.
 

1.jpg

 

Oasis Focuser Rose is the second generation of the Astroasis electronic focuser. On the basis of the first generation, the second generation has made significant improvements and it is a perfect electronic focuser for astrophotography.
 
Compared with the first generation, the second generation has made the following improvements:
1) Convenient power supply — It can be powered by either the USB Type-C port or the 12V DC port.

2) Stall detection — Motor stall detection feature prevents the telescope focuser and the gears from being damaged in case the telescope focuser moves out of the minimum or maximum range or in other cases that are not expected.

3) Built-in heating module — The built-in heating module allows the focuser to work in low ambient temperature conditions for North China, Europe, North America users when capturing in winters. The heating module can be controlled at a constant temperature when heating so it's easy to use.

4) Gear locator — The gear locator helps user to install the gear in the right place.

5) Improved reliability  — Motor is upgraded to improve reliability. PCB is re-designed to improve reliability of power module, USB/DC/Temperature sockets etc.

6) Better connection method — The connection method of the fixed-part and the rotatable part is improved. The connection of the fixed-part and the rotatable part is more stable.

7) More compact dimensions — Compared to the first generation, the second generation Oasis focuser body has a 14.5mm reduction in the length and a 4mm reduction in the diameter of the rotatable part. It is also 20% lighter than the first generation.

Oasis Focuser Rose inherits all the excellent features of the first generation Oasis Focuser, including:
1) Clutch function — Easy and fast switching between motor and manual focusing
2) Bluetooth function — Mobile devices such as mobile phones can be used to control the focuser via Bluetooth
3) High precision — Micron precision for each motor step
4) Ability to drive heavy load — Testing indicates that it can driver net loads more than 5Kg
5) Excellent backlash compensation performance — Gears and rigid components provide excellent backlash compensation performance
6) Easy to install — Easy to install or uninstall focuser body. Only one screw needs to be used to install or uninstall focuser body. And it can be installed on many telescope focusers
7) High integrated — Except for the ambient temperature probe, all functions and components (including motor, controller board etc.) are implemented and integrated in the single compact focuser body

 

In addition, this product has the following features:
1) Support USB HID device interface. Device driver installation is not required for Windows, Linux and macOS operation systems.
2) Support ASCOM interface
3) Support INDI
4) Support INDIGO
5) Has two temperature sensors, one monitors board temperature, the other monitors ambient temperature
6) Has beep generator for tips or alarms

Looks great, and with all the new features will be even better than the first version, looking forward to seeing one in the flesh…

Here are graphs of the auto-focus curve we got by running 12 consecutive auto-focus sessions using Oasis Focuser Rose and NINA. The telescope used is SkyRover 102 APO Pro. As we can see the focus positions after each auto-focus are very close, with the minimum position being 39582 and the maximum position being 39593. On the SkyRover 102 APO, the moving distance of each motor step is 0.8μm. So the maximum position deviation between each of the 12 consecutive auto-focus is less than 9μm. All the hyperbolic fitting coefficient of determination (R2) are above 0.99, indicating that the focusing results have high stability and accuracy.

Please note:
Many factors may impact the auto-focus result, such as wind, seeing, and the auto-focus parameter settings etc. In order to get good auto-focus results like the ones shown above, we need to do many things right.

Is the focuser compatible with Takahashi FC-100DZ? Could you provide some additional details to those in the Installation Manual?

The focuser of FC-100DZ is the similar of the focuser of Takahashi TOA 130-NS or Takahashi Epsilon newtonians. Yes Oasis Focuser can be installed on those telescopes. The installation requires a universal adapter. For the details of the universal adapter, please refer to the following page:

https://www.astroasi...focuser/62.html


For the details of the installation steps on Takahashi Epsilon-like focusers, please refer to chapter 4.3 of the following document:

Looking good guys, can’t wait to get mine for testing, I have gotten rid of all my other focus motors now, and will be using these on all of my scopes eventually….

i love the compactness and fine resolution of them, and this new one is even smaller…

When installing on Askar SQA55, the belt tension can be adjusted easily just by rotating the Oasis Focuser body. The installation is very simple. Everything is neat and graceful.

 

The focusers used in the pictures are the old version Oasis focuser. If the Rose version is used, it will be more compact.

Hi, our user will install the focuser on William Optics WIFD Redcat 61. It looks the focsuers of the MiniCat 51 and the WIFD RedCat 61 are similar. I will be back to you when we confirm the installation on RedCat 61. Thanks.

Hello, the following picture is the William Optics SpaceCat 51 WIFD with the old version Oasis Focuser installed on it. Oasis focuser main body can be installed on it by using a clamp. Only one screw needs to be tighten/loosen for attaching/detaching the Oasis focuser main body.

Other users will install the new version Oasis Focuser (the Roser Focuser) on other William Optics WIFD scopes. I will upload the pictures when I have them.

Thanks for the update. Is that the included clamp or a different size?

Hello, the installation uses the 33mm clamp and B6 gear. Normally the clamp included in the focuser suit may be different in order to fit different telescopes. So it's better to confirm with the seller when ordering. The B6 gear is always included in the suit. Thanks.

Hi, the installation on William Optics Pleiades 68mm telescope is shown as in the following customer pictures. This telescope has WIFD focuser too. I believe the same clamp can fit all the William Optics WIFD focusers.

Oasis Focuser on Celestron RASA11. On Celestron C11/C14 we can use the same adapter and install in the same way. Both manual focusing and motor focusing are supported.

Just came across your product while watching a YT video. I checked the list of supported telescopes and did not see the Sharpstar SCA260 on the list. Is there anyway to install this on that scope?
