APS-C Adapter (M42 x 0.75 mm)
17 mm base adapter
for most ZWO/QHY cameras
24 mm base adapter
for QHY8L/10/12
Both versions of the base adapter (17/24 mm) are presented
Standard spacer (9.5 mm, required to achieve the correct back focal length w/o FW))
17 mm base adapter + 9.5 mm spacer = 26.5 mm
17 mm adapter is ideal for monochrome camera (ASI1600MM for example) with filter wheel. 17 mm (ASCOM Canon Lens Controller) + 20 mm
(ZWO EFW) + 6.5 mm (ZWO cooled camera) = 43.5 mm.

26.5 mm adapter (17 mm base adapter + 9.5 mm spacer) is suitable for color camera (ASI294MC for example). 26.5 mm (ASCOM Canon Lens
Controller) + 11mm (T2 ring) + 6.5 mm (ZWO cooled camera) = 44 mm.
Full Frame Adapter for SBIG STL cameras - [13.5 mm]
To install this adapter, you must remove the standard mounting flange. SBIG STL series camera (for example SBIG STL11000) has a back focal
length of about 30.4 mm w/o this flange. Use 6-32x1/4" screws for mounting the adapter.
APS-C / Full Frame Adapter for QHY cameras (M54 x 0.75 mm) - [19.5 mm]
M54 x 0.75 mm adapter has a square window and need to be properly oriented according the camera sensor. This can be
easily achieved using standard QHY angle adjustment adapter ring that comes with the camera.
Full Frame Adapter for ZWO ASI094MC camera - [25.5 mm]
This adapter has 9 holes, 3 of which are designed for attaching the adapter to the camera. Other 6 holes are needed for access to the push/pull
screws. So you have the opportunity to make alignment procedures. Use a hex key for this. In addition, ASI094MC tilt adapter allows you to
change back focal length within 3 mm.

Lens API
User level software communicates with ASCOM Lens Controller via a simple commands transfer protocol. Commands transmit as
a specially formed text units. You can use this protocol autonomously or embed it in your own software products.
All you need is a development environment that allows to interact with COM ports.
Tools:  your own software solutions
Platforms:  any supported platforms

Hardware drivers
ASCOM Canon Lens Controller Mark II uses a standard and popular FT232RL chip for USB connection instead of a cheap CH340G
in old version. Usually these drivers are installed automatically (you may need to connect to the Internet), but if it doesn't happen,
then you can install them manually. FT232RL is the most reliable and frequently used chip for creating virtual COM ports.
