Optec

The QHY163 should have 17,5mm of backfokus, but please verify this in your camera manual as we don't have the camera here.

The 8" EdgeHD reducer requires a distance of 105mm to the sensor, so we have 87.5mm for the UFC.

You need:
2459128 - Adapter for SC-thread of the telescope/reducer - 1mm length
2459110 - UFC base - 13mm length
2459115 - T-2-Adapter with male thread, fits into your camera - 2mm length

For the remaining 71,5mm, you can use several extensions, e.g.
- Baader UFC S70 Extension 15mm # 2459142
- Baader UFC S70 Extension 40mm # 2459143
- Baader UFC S70 VariLock 15-20mm extension # 2459145
If you set the VariLock to 16.5mm, you should have the perfect distance.

You can also use the smaller T2-extension tubes and Varilocks instead:
- Baader T-2 / 40 mm Extension Tube (T-2 part #25B) # 1508153
- Baader VariLock 46, lockable T-2 ExtensionTube 29-46mm with spanner tool (T-2 part #25V) # 2956946

It is in general a good idea to keep the filters closer to the camera, so the UFC-extensions should be better that the T-2-extensions - the closer a filter is, the less will optical distortions of the filter be a problem.

In addition, you need the filter sliders according to your filters:
- Baader UFC 2" (M48) Filter Slider # 2459112
- Baader UFC D 50.4 Filter Slider # 2459113
- Baader UFC 50x50 Filter slider # 2459114
- Baader UFC D 36 mm AUX-Filter-Holder (requires #2459113) # 2459152
- Baader UFC 1¼" AUX-Filter-Holder (requires #2459113) # 2459153

Currently there is no linux/INDI driver.

If you need to control the SteelDrive II on a linux machine,
we can provide you with the serial command protocol for direct communication with the device.

Yes, you can - please take a look at page 5 of the PDF https://www.baader-planetarium.com/en/downloads/dl/file/id/444/product/3119/digiscoping_camera_adaptations_for_afocal_photography_and_eyepiece_projection.pdf which we have also linked to in the Downloads section.

You need
- Hyperion / Morpheus T-Adapter M43/T-2 #2958080
- 1" C-Mount T-2 adapter Filterholder #2958520

And spacers between these two adapters, depending on the size of your sensor and the desired effective focal length. The larger the sensor, the farther away should it be from the eyepiece to avoid distortions at the edge of the image.

The diameter is ca. 6cm, the height (without screw) ca. 4.6cm

Thank you for your keen eye - the brass ring had indeed moved on the part we used for the photo. If it is in the right position, it covers both locking screws, and nothin will happen to the eyepiece. It can be moved easily into a conveniant position, where both locking screws are covered.
