Wired video collimation from CATSEYE

CATSEYE Collimation, a long-standing manufacturer of precision collimation tools for Newtonian telescopes, has released a new addition to its product lineup: the BLACKCAT XLV Wired “VIDEO” Collimation System. This product introduces a video-assisted method of collimation, allowing users to view collimation alignment in real-time on an LCD monitor rather than relying solely on direct visual inspection through a Cheshire eyepiece.

CATSEYE BLACKCAT XLV wired collimation system

Collimation is an essential step in optimizing the performance of Newtonian telescopes, ensuring that light is properly directed within the optical system. Traditionally, Cheshire eyepieces and autocollimators have required users to physically look through the tool, often requiring multiple trips back and forth between the focuser and the primary mirror adjustment screws. It aims to simplify this process by integrating a color CCTV camera within the unit, allowing for continuous real-time monitoring of the alignment from the rear of the telescope. This setup reduces the need for repeated repositioning and helps users make precise adjustments more efficiently.

Its available in a limited quantity. Pricing is set at $269 for an a-la-carte purchase. Users ordering a simultaneous kit that includes the BLACKCAT XLV can opt for a $205 upgrade in place of the standard BCXL-A Cheshire.

The system follows the same principles as traditional passive collimation tools but integrates a digital component to enhance usability. The built-in CCTV camera provides a live video feed of the alignment patterns typically seen in a Cheshire eyepiece. This image is displayed on an LCD monitor, which can be handheld or mounted near the telescope's rear for easier viewing while making adjustments.

By eliminating the need to move back and forth between the front and rear of the telescope, users can now dynamically observe their adjustments in real time, reducing the time and effort typically involved in the collimation process. This feature is particularly beneficial for users of large Dobsonian and truss telescopes, where physical repositioning can be cumbersome.

Other collimation tools from CATSEYE Collimation

For those new to CATSEYE Collimation’s products, the company has been offering collimation solutions since 2010, with a range of tools designed to provide precise alignment for Newtonian telescope users.

• INFINITY XLKP-A Autocollimator: This tool is designed for high-precision collimation by providing multiple reflections of alignment patterns, helping astronomers fine-tune their optical systems with greater accuracy. The dual-pupil design allows users to see subtle misalignments that might not be visible with a standard Cheshire eyepiece alone.
• BLACKCAT XL-A Cheshire: A 2-inch Cheshire eyepiece that provides clear, high-contrast alignment feedback. This tool is often used in conjunction with autocollimators for a complete collimation solution.
• XLKP Autocollimator: The most recent advancement in CATSEYE’s lineup, offering further refinement in alignment accuracy for experienced users who require the most precise collimation possible.
• HOTSPOT Primary Mirror Center Spots: Pre-cut reflective markers that improve the visibility of collimation alignment points, making the process easier when using Cheshire eyepieces and autocollimators. These center spots come in different styles to accommodate various collimation techniques.

CATSEYE’s tools are designed to be used individually or as a complete system for telescope owners looking to optimize their collimation workflow. Some key benefits of this system include:

• Real-Time Feedback: Unlike traditional methods that require users to move between the focuser and the adjustment screws, the BLACKCAT
• XLV allows astronomers to see the alignment cues instantly as they make adjustments.
• Reduced Strain and Effort: Eliminating the need to bend down or reposition multiple times helps reduce physical strain, particularly for users working with large telescopes.
• Improved Precision: The parallax-free video feed allows users to achieve highly accurate collimation without the small misalignments that can sometimes occur with direct visual methods.

While traditional Cheshire and autocollimator tools remain effective, this new system may appeal to several types of users:

• Owners of Large Dobsonian Telescopes: Large telescopes often require collimation adjustments at the primary mirror, which can be challenging when needing to move back and forth to check alignment. The video feed simplifies this process.
• Astronomers Who Collimate Frequently: Observers who regularly fine-tune their optics before each session may appreciate the time-saving aspect of video-assisted monitoring.
• Outreach and Educational Use: The live video display can be useful for astronomy educators and clubs, allowing multiple people to observe the collimation process at the same time.
