A precise adjustment of the optical system and the focal point is necessary for optimal imaging performance, both visually and photographically. You will find your tools here.
Howie Glatter Flug 2" Barlow Element to convert your Laser Collimator to a Barlowed Laser Collimator for Truss Tube Dobsonians with 2" Feathertouch Focuser.
The Artesky 650nm laser collimator is crafted from brushed aluminum with a precisely calculated diameter of 2" (50.8mm), fitting perfectly into your focuser! The projected laser beam, certified with a wavelength of 650nm, is very thin and well-defined so you can perform collimation both at night and during the day.
The all new revolutionary collimator for reflecting telescopes.
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.
