Additional RS232 Commands

Send Any Track Rate Through RS232 To The Hand Control

1.Multiply the desired tracking rate (arcseconds/second) by 4. Example: if the desired trackrate is 150 arcseconds/second, then TRACKRATE = 600

2.Separate TRACKRATE into two bytes, such that (TRACKRATE = TrackRateHigh*256 + rackRateLow). Example: TrackRateHigh = 2 TrackRateLow = 88

3.To send a tracking rate, send the following 8 bytes:

a.Positive Azm tracking: 80, 3, 16, 6, TrackRateHigh, TrackRateLow, 0, 0

b.Negative Azm tracking:80, 3, 16, 7, TrackRateHigh, TrackRateLow, 0, 0

c.Positive Alt tracking: 80, 3, 17, 6, TrackRateHigh, TrackRateLow, 0, 0

d.Negative Alt tracking: 80, 3, 17, 7, TrackRateHigh, TrackRateLow, 0, 0

4.The number 35 is returned from the handcontrol

Send A Slow-Goto Command Through RS232 To The Hand Control (note: Only valid for motorcontrol version 4.1 or greater)

1.Convert the angle position to a 24bit number. Example: if the desired position is 220°, then POSITION_24BIT = (220/360)*224 = 10,252,743

2.Separate POSITION_24BIT into three bytes such that (POSITION_24BIT = PosHigh*65536 + PosMed*256 + PosLow). Exampe: PosHigh = 156, PosMed = 113, PosLow = 199

3.Send the following 8 bytes:

a.Azm Slow Goto: 80, 4, 16, 23, PosHigh, PosMed, PosLow, 0

b.Alt Slow Goto: 80, 4, 17, 23, PosHigh, PosMed, PosLow, 0

4.The number 35 is returned from the handcontrol

Reset The Position Of Azm Or Alt

1.Convert the angle position to a 24bit number, same as Slow-Goto example.

2.Send the following 8 bytes:

a.Azm Set Position: 80, 4, 16, 4, PosHigh, PosMed, PosLow, 0

b.Alt Set Position: 80, 4, 17, 4, PosHigh, PosMed, PosLow, 0

3.The number 35 is returned from the handcontrol

4.Note: If using Motorcontrol version less than 4.1, then send:

a.Azm Set Position: 80, 3, 16, 4, PosHigh, PosMed, PosLow, 0

b.Alt Set Position: 80, 3, 17, 4, PosHigh, PosMed, PosLow, 0

C10-N, C8-NGT, C8-N specifications

The Celestron C8-NGT, C8-N, and C10-N telescopes represent a range of superior astronomical instruments that cater to both novice and experienced astronomers alike. Among these, the C8-NGT combines the advanced features of a computerized telescope with the simplicity of a Newtonian design. Its 8-inch aperture allows for impressive light-gathering capability, making it ideal for observing distant galaxies, star clusters, and nebulae. The GoTo mount enhances usability, enabling users to locate celestial objects effortlessly with the push of a button.

The C8-N, also featuring an 8-inch aperture, stands out with its open tube design that provides maximum airflow and minimizes thermal issues, ensuring optimal performance. The scope is designed with user-friendly adjustments and a sturdy equatorial mount, allowing for smooth tracking of celestial objects. Its high-quality optics provide sharp images and incredible clarity, making it suitable for both planetary and deep-sky observations.

On the other hand, the C10-N is the largest in this lineup, boasting a 10-inch aperture that dramatically enhances its light-gathering ability. This larger size makes the C10-N a powerhouse for serious astronomers looking to explore fainter objects and intricate details within astronomical features. Like the C8-N, it employs a Newtonian reflector design, allowing for a compact and manageable profile, while still providing stunning visuals across a range of celestial bodies.

All three telescopes incorporate Celestron's commitment to creating durable, robust, and user-friendly systems. They utilize premium quality glass and optics, which are coated to improve light transmission and provide high-contrast images. Additionally, they are designed with ease of assembly and portability in mind, catering to astronomers who enjoy observing in various locations.

The Celestron C8-NGT, C8-N, and C10-N serve as excellent options for anyone looking to deepen their astronomical pursuits, offering a blend of advanced technology, high-quality optical performance, and user-friendly features. Whether you're a beginner eager to peer into the wonders of the universe or an experienced observer at the peak of your skills, these telescopes offer a remarkable means to expand your cosmic horizons. With precision engineering and thoughtful design, Celestron continues to be a trusted name in the world of astronomy.
