TS-Optics Adaptor with female T2 thread and male M48x0,75 filter thread

The adapter extends a male T2 thread to M48x0.75 (2") filter thread without increasing the length.

• Female thread: continuous T2 - M42x0.75
• Male thread: continuous 2" filter thread - M48x0.75
• Length: 4 mm - the mechanical length is optically not effective, as the adapter is completely sunken in the connection adapter

Artesky Fast Focus Plane Kit

Allows easy adjustment of the focal plane and backfocus

• Tilter unit with 36 to 39 mm thickness
• Three female adapters, four male adapters
• Works especially well with CMOS cameras with up to 17.5 mm backfocus

• The new version of the OCAL collimator uses a larger front lens and a CMOS sensor. The new sensor is much more light sensitive. This allows adjustment even under darker conditions. If the image is too bright, you can adjust down via gain and exposure time.
• The improved optics of the OCAL version 3.0 ensure that critical areas can now be focused even better.
• The area in the center around the lens of the OCAL is now easier to distinguish from the background. This enables clean alignment even under difficult conditions, for example when a center mark obscures the lens.
• The clarity of the image has been significantly improved. Especially with a corrector connected, the image is now much better than with previous models.
• Suitable for Windows and Android.

• focusers from TS-Optics, Astroshop and many other brands
• Enables the use of the EAF motorised focus system from ZWO
• Manufactured using 3D printing
• Resistant to UV and temperatures up to approx. 80° C
