Paramount MyT Series 6

(0)

From $16,370.00

The Paramount MYT Series 6 delivers exceptional performance made possible through its artful integration of precision mechanics, advanced control system electronics, and the uniquely capable Paramount Software Suite (included).

Skillfully carrying up to 32 kg of telescopes, cameras, and accessories, the Paramount MYT can help you create your next astrophoto masterpiece, at home, or on the go.

New features include:

All new MKS 6000 offers built-in Ethernet, USB-C and Wi-Fi communication options and more.
Optional Power On and Observe™ on-axis absolute encoder technology. No homing required and no periodic error.
High-amperage XT60 connectors can supply continuous 12V DC power up to 60A.

Introducing the new Paramount MYT Series 6 portable observatory.

Its new features include a 40% instrument capacity increase, an option for absolute digital encoders, and multiple connectivity options.

Being the lightest of all the Paramounts, the Paramount MYT Series 6 is the ultimate grab-and-go observatory.

On-axis Absolute Encoders vs. Motor-based Encoders.

Paramount's equipped with on-axis absolute encoders know where they are at all times. Paramount's with incremental encoders (or motor-based encoders) know only how far they have moved since they were initialized using a nightly process called homing.

The crucial additional difference is that the on-axis absolute encoders are fitted directly to the mount axes themselves, bypassing the worm drives. Paramount's with incremental encoders are fitted to the worms instead, which means that with incremental encoders alone, periodic errors in the worm drive show up in the tracking. These mounts must be calibrated and corrected using a process called periodic error correction (PEC), which measures and records the repeatable gear train errors and removes them. (TheSky features advanced, multi-harmonic PE detection and PEC calibration that minimizes periodic error in mounts with incremental encoders.)

For mounts with incremental encoders, homing re-zeros the encoders when precise sensors on each of the axes are reached. From then on, the incremental encoders are in effect delivering absolute readings.

However, the crucial additional difference remains, namely that the incremental encoder system is behind the worm drive, and periodic error correction is still required to get the best out of the RA tracking.

High-resolution on-axis absolute encoder technology is significantly more expensive than incremental encoders.

Are on-axis absolute encoders right for me ?

The short answer is, “it depends.”

Gear-driven Paramounts equipped with on-axis absolute encoders do not have periodic error, require no mechanical initialization (or homing), and the number of TPoint pointing samples needed for precision calibration is reduced.

These advantages expedite nightly setup, negate one-time periodic error training, and shorten the calibration process require to achieve spectacular pointing and tracking performance. However, the Paramount worm gear's uncorrected periodic error is low (below 7 arc seconds peak to peak), and, after a one-time PE training, periodic error correction (PEC) generally make it negligible. The Paramount without on-axis absolute encoders requires a nightly Find Home process that usually takes a minute or less to complete.

So, at least with Paramounts, periodic error is effectively in the noise, and homing straightforward.

What about pointing and tracking?

Without on-axis absolute encoders, Paramounts routinely produce 5-to-10-minute unguided exposures; many have reported 20 minutes. Also without on-axis absolute encoders, Paramount’s produce all-sky pointing accuracies at or below 30 arcseconds RMS (usually less than 15 arcseconds on fixed mirror telescopes).

Paramount’s exceptional software makes the above performance possible. TheSky Professional edition, in conjunction with TPoint™ and ProTrack™ the mount’s position is continually updated in both axes to correct system-wide pointing and tracking errors caused by tube flexure, atmospheric refraction, polar misalignment, harmonic errors from mis-centered encoders and/or worm gears, and more.

On-axis absolute encoders alone cannot correct these errors which exist with all telescopes. A properly applied telescope model is necessary to achieve superior pointing and tracking.

So are on-axis absolute encoders right for you? Perhaps if you want to enjoy the conveniences mentioned above. And for many, that’s enough. With that said, the optional on-axis 26-bit Renishaw absolute encoders with 0.02 arc second precision are the finest available and they operate in temperatures between +80°C and –40°C.

Hardware Specifications

32 kg instrument capacity; 64 kg maximum payload capacity (instruments + counterweights)
All sky pointing accuracies at or below 30 arcseconds RMS (see Software Specifications below for details)
Unibody mount design weighs 16 kg without counterweights or counterweight shaft
Maximum seven (7) arcseconds peak-to-peak periodic error before correction
After a one-time training, periodic error is 1 arcsecond, peak-to-peak or less
Optional 26-bit Renishaw encoders eliminate periodic error and the need for homing; operates in temps as low as –40° C
If you skip encoders now and later decide you want them, they can be retrofitted on Series 6 Paramounts
As there’s some confusion about what encoders can and cannot do, there’s an FAQ below that elaborates on that and whether they’re right for you
Its encoder cables are located inside the mount to help prevent snags.
All electronics and through-the-mount cables are housed inside the mount with ample room for additional cables

Two-port USB 2.0 hub located on the instrument panel
Redesigned Versa-Plate™ (included) accepts most telescopes and makes mounting them a breeze
48V DC power supply and PC-to-mount USB and Ethernet cables included
9 kg counterweight included and can balance 9 kg. You may need to purchase more for heavier payloads.
Belt-driven gears with spring-loaded worm gears produce virtually zero backlash
Durable and fade-resistant red powder coating and black anodized finish; components are aluminium
Clutch-free design helps maintain its TPoint™ assisted pointing accuracy
AutoHome™ homing capability ensures the mount always knows its orientation (after performing an initializing process called “homing” that typically takes less a minute or less)
Calibrated azimuth and elevation polar alignment adjustments speed polar alignment

Software Specifications

Paramount’s unequaled pointing and tracking wouldn’t be possible without its TPoint™ and ProTrack™ software.
By employing TPoint’s calibration and telescope modeling tools, you’ll enjoy all-sky pointing accuracies at or below 30 arcseconds RMS. Nothing outperforms that.
Operating in conjunction with TPoint ™, ProTrack™ continuously updates the mount’s position across both axes to correct system-wide tracking errors including tube flexures, atmospheric refraction, polar misalignment, harmonic errors from mis-centered encoders, and more.
On-axis absolute encoders alone cannot correct these errors which exist with all telescopes. A properly applied telescope model is necessary to achieve superior tracking.
Without encoders, Paramounts can deliver uncommonly long unguided exposures (one customer reported 20 minutes).
For more information about what encoders can and cannot do, please see the FAQ below.
All the included software is integrated into a single, easy-to-use, application consisting of TheSky™ Professional, TPoint™, Cameras+, Domes, Multi-OS+, and Weather modules.
You can control all your astrophotography-related cameras and devices with this one app.
It runs on macOS™, Windows™, Ubuntu™, and Linux (x86_64 and ARM64 architectures.
Regardless of the operating system you run it on, it appears and operates identically. You can even switch between operating systems and its license allows up to six computers. Why paint yourself or your institution into a corner?
Absent ProTrack™ which is unique to Paramount, the included software is sold separately as TheSky™ Universal Bundle and represents a $1,095 value.

Built-in cable management

- - USB 3.0 USB hub (4 ports)
  - 2.1mm Power port (3 ports)
  - 3 serial ports on the back of the saddle
  - The EQ8-R features built-in cable management. This removes cable drag from hanging cables and reduces the risk of cables getting caught during imaging session. This capability also improves the mounts capabilities for remote use.

The built-in USB 3.0 hub allows you to simply plug in your camera, guider, filter wheel and other USB accessories into the hub below the saddle plate and connect them using a single USB cable plugged into the rear of the mount. No more tangled mess of cabled hanging or need for multiple cables running around the mount.

Another addition to the cable management system is the three built-in 2.1mm ports situated next to the USB hub. This allows your accessories to also be powered through the mount. This reduces the need for multiple power adapters and other accessories. The ports can be run off of a single power source providing a cleaner set up and less cables.

On the gear of the saddle are three serial ports for various accessories such as ST4 guide cables and other serial based accessories. Like the rest of the cable management this reduces the hanging cables and provide a neat connection to the mount.

Motor Positioning

EQ8-R feature improved balance from their predecessor with redeposited motor housings. This improve the mount’s balance over all.

Belt Drive

Both mounts feature belt drive on both the RA and Dec axis. This allows for smoother guiding and reduced backlash.

Auto-Home

EQ8-R feature built-in homing sensors. This allows the mount to know its positioning more accurately from its start positioning.

Improved Clutches

The EQ8-R models feature improved clutches allowing for sturdier lock under heavy loads. Simply use the large levers to engage or disengage the axis of choice. The clutch lever are larger than the original EQ8 making it easier to adjust with gloves

PC Direct Connect

EQ8-R also feature the new PC direct connect feature. Now you can easily connect your mount to your computer without the need of a hand controller.

DESCRIPTION

The EQ8-Rh provides the next generation of Sky-Watcher’s popular high capacity mount, the EQ8.

The R models offer a refined design to allow for better balance and more modern features to cater to today’s high end imagers.

Built-in cable management

- - USB 3.0 USB hub (4 ports)
  - 2.1mm Power port (3 ports)
  - 3 serial ports on the back of the saddle
  - The EQ8-Rh features built-in cable management. This removes cable drag from hanging cables and reduces the risk of cables getting caught during imaging session. This capability also improves the mounts capabilities for remote use.

The built-in USB 3.0 hub allows you to simply plug in your camera, guider, filter wheel and other USB accessories into the hub below the saddle plate and connect them using a single USB cable plugged into the rear of the mount. No more tangled mess of cabled hanging or need for multiple cables running around the mount.

Another addition to the cable management system is the three built-in 2.1mm ports situated next to the USB hub. This allows your accessories to also be powered through the mount. This reduces the need for multiple power adapters and other accessories. The ports can be run off of a single power source providing a cleaner set up and less cables.

On the gear of the saddle are three serial ports for various accessories such as ST4 guide cables and other serial based accessories. Like the rest of the cable management this reduces the hanging cables and provide a neat connection to the mount.

Motor Positioning

EQ8-RH feature improved balance from their predecessor with redeposited motor housings. This improve the mount’s balance over all.

Belt Drive

Both mounts feature belt drive on both the RA and Dec axis. This allows for smoother guiding and reduced backlash.

Auto-Home

EQ8-RH feature built-in homing sensors. This allows the mount to know its positioning more accurately from its start positioning.

Improved Clutches

The EQ8-RH models feature improved clutches allowing for sturdier lock under heavy loads. Simply use the large levers to engage or disengage the axis of choice. The clutch lever are larger than the original EQ8 making it easier to adjust with gloves.

PC Direct Connect

EQ8-RH also feature the new PC direct connect feature. Now you can easily connect your mount to your computer without the need of a hand controller. When paired with the SynScan Pro app. for Windows the mount can be aligned and controlled direct from a PC. This makes imaging refined and easier, especially for those with permanent set ups.

EQ8-Rh On-Axis Encoder

The EQ8-RH takes a step further with all the listed features above but adds a higher level of precision. The Rh (h for High Res.) features an on-Axis Renishaw TONic incremental, 11.8 million tick, encoder on the RA axis. This allows the mount to have extremely precise tracking and guiding for long exposure imaging. With the encoder built onto the RA axis this removes periodic error to nearly zero in RA with an accuracy of 0.11 arc-seconds! The EQ8-Rh offers a pro level mount for the series astro imager.

Vixen Telescope SXD2 Equatorial Mount WL

(0)

$3,999.00

Deluxe equatorial mount with wireless control

The SXD2 is the deluxe type of thSX2 equatorial mount in response to higher precision tracking and mounting larger optical tube and photographic equipment. A polar alignment scope comes as standard for serious astrophotographers.

Phone and iPad/Tablet Control

This is a high precision equatorial mount with improved performance in every details from raw materials, number of bearings and cutting and processing every parts on the entire process. The equatorial mount is supplied with the wireless unit which allows you to make your smartphone or tablet as controller for celestial navigation as high precision tracking.

Wireless celestial navigation

STAR BOOK Wireless App inheriting the DNA of popular STAR BOOK TEN Controller

If you tap the celestial object you want to see on the star chart, it will be automatically slew into the field of view and tracking will start. Following the display of the STAR BOOK TEN controller, which has been highly evaluated for its comfortable operability, even existing STAR BOOK TEN users can use it without any discomfort.

Increased loading capacity from 12kg (SX2 equatorial mount) to 15kg

Rigidity and precision have been improved by changing the right ascension and declination rotation axis from aluminium alloy to thick steel, and changing the gear that is the key to the drive from aluminium to brass. Consequently the loading weight has also increased from 12kg of the SX2 equatorial mount to 15kg, making it possible to replace with a larger optical tube and add a SLR camera, CMOS camera, etc.

High precision for smoother motion.

A variety of parts of the mount have been improved such as by adding bearings to the right ascension, declination axes and worm screws, and reducing the eccentricity of the worm screw, and lapping (polishing) has been performed along with the entire circumference of the worm wheel to achieve extremely smooth motion.

Pulse motors improve stability and response of motions

Precision pulse motor (stepping motor) with micro-step motion control that drives at 250 pulses/second is used instead of the conventional DC motor offering very smooth control from low speed to high speed, and response to operation improved.

Easy-to-use polar alignment scope

It is a device that allows high-precision installation of equatorial mount with easy operation (for the northern and southern hemispheres). Built-in scale that shows the starry sky near the north celestial pole and south celestial pole).

The scale itself glows red, so dark stars don't get lost in the background. All adjustments can be made while looking through the polar alignment scope, making it very convenient in dark places. The brightness of the scale is adjustable in 8 steps, so you can use it at your preferred brightness. In addition, it will automatically turn off in 1 to 2 minutes (gradual dimming), and you can prevent forgetting to turn it off after use

Rationality based on mechanics: weightless structure (reduction of moment load)

The weightless structure cultivated in the SX series was inherited. By concentrating the main weight-bearing parts such as the motor, worm shaft, and worm wheel on the weight side, and shortening the distance from the fixed point to the mounting block (the place where the equipment is mounted), advantageous structure in terms of dynamics is adopted.

You can balance the weight with the loading equipment with less counterweight. Depending on the weight of the loading equipment, counterweight less is also possible.

Retractable counterweight shaft convenient for setup and withdrawal of equipment

Stainless steel with excellent corrosion resistance is used for the counterweight shaft. Retractable type that can be stored in the equatorial mount body allows speedy setup. You can use the counterweight common to the SX series of 20 mm in diameter.

Paramount ME Series 6

(0)

From $36,350.00

Introducing the new Paramount ME Series 6 observatory workhorse.

The Paramount ME Series 6 represents the latest in gear-driven GEM performance.

Its new features include a state-of-the-art MKS 6000 telescope control system that lets you connect via USB C, Ethernet, and Wi-Fi. Its two-port USB 2.0 hub is conveniently located on the instrument panel

The Paramount ME Series 6 remains an observatory favorite among professional and advanced-amateur astronomers.

On-axis Absolute Encoders vs. Motor-based Encoders.

Paramount's equipped with on-axis absolute encoders know where they are at all times. Paramount's with incremental encoders (or motor-based encoders) know only how far they have moved since they were initialized using a nightly process called homing.

The crucial additional difference is that the on-axis absolute encoders are fitted directly to the mount axes themselves, bypassing the worm drives. Paramount's with incremental encoders are fitted to the worms instead, which means that with incremental encoders alone, periodic errors in the worm drive show up in the tracking. These mounts must be calibrated and corrected using a process called periodic error correction (PEC), which measures and records the repeatable gear train errors and removes them. (TheSky features advanced, multi-harmonic PE detection and PEC calibration that minimizes periodic error in mounts with incremental encoders.)

For mounts with incremental encoders, homing re-zeros the encoders when precise sensors on each of the axes are reached. From then on, the incremental encoders are in effect delivering absolute readings.

However, the crucial additional difference remains, namely that the incremental encoder system is behind the worm drive, and periodic error correction is still required to get the best out of the RA tracking.

High-resolution on-axis absolute encoder technology is significantly more expensive than incremental encoders.

Are on-axis absolute encoders right for me ?

The short answer is, “it depends.”

Gear-driven Paramounts equipped with on-axis absolute encoders do not have periodic error, require no mechanical initialization (or homing), and the number of TPoint pointing samples needed for precision calibration is reduced.

These advantages expedite nightly setup, negate one-time periodic error training, and shorten the calibration process require to achieve spectacular pointing and tracking performance. However, the Paramount worm gear's uncorrected periodic error is low (below 7 arc seconds peak to peak), and, after a one-time PE training, periodic error correction (PEC) generally make it negligible. The Paramount without on-axis absolute encoders requires a nightly Find Home process that usually takes a minute or less to complete.

So, at least with Paramounts, periodic error is effectively in the noise, and homing straightforward.

What about pointing and tracking?

Without on-axis absolute encoders, Paramounts routinely produce 5-to-10-minute unguided exposures; many have reported 20 minutes. Also without on-axis absolute encoders, Paramount’s produce all-sky pointing accuracies at or below 30 arcseconds RMS (usually less than 15 arcseconds on fixed mirror telescopes).

Paramount’s exceptional software makes the above performance possible. TheSky Professional edition, in conjunction with TPoint™ and ProTrack™ the mount’s position is continually updated in both axes to correct system-wide pointing and tracking errors caused by tube flexure, atmospheric refraction, polar misalignment, harmonic errors from mis-centered encoders and/or worm gears, and more.

On-axis absolute encoders alone cannot correct these errors which exist with all telescopes. A properly applied telescope model is necessary to achieve superior pointing and tracking.

So are on-axis absolute encoders right for you? Perhaps if you want to enjoy the conveniences mentioned above. And for many, that’s enough. With that said, the optional on-axis 26-bit Renishaw absolute encoders with 0.02 arc second precision are the finest available and they operate in temperatures between +80°C and –40°C.

Hardware Specifications

109 kg instrument capacity; 218 kg maximum payload capacity (instruments + counterweights)
All sky pointing accuracies at or below 30 arcseconds RMS
Unibody mount design weighs 38 kg without counterweights or counterweight shaft
Maximum seven (7) arcseconds peak-to-peak periodic error before correction
After a one-time training, periodic error is 1 arcsecond, peak-to-peak or less
Optional 26-bit Renishaw encoders eliminate periodic error and the need for homing; operates in temps as low as –40° C
If you skip encoders now and later decide you want them, they can be retrofitted on the Paramounts ME Series 6
As there’s some confusion about what encoders can and cannot do, there’s an FAQ below that elaborates on that and whether they’re right for you

Calibrated azimuth and elevation polar alignment adjustments speed polar alignment

Software Specifications

Paramount’s unequaled pointing and tracking wouldn’t be possible without its TPoint™ and ProTrack™ software.
By employing TPoint’s calibration and telescope modeling tools, you’ll enjoy all sky pointing accuracies at or below 30 arcseconds RMS. Nothing outperforms that
Operating in conjunction with TPoint ™, ProTrack™ continuously updates the mount’s position across both axes to correct system-wide tracking errors including tube flexures, atmospheric refraction, polar misalignment, harmonic errors from mis-centered encoders, and more.
On-axis absolute encoders alone cannot correct these errors which exist with all telescopes. A properly applied telescope model is necessary to achieve superior tracking.
Without encoders, the Paramount ME Series 6 can deliver uncommonly long unguided exposures (one customer reported 20 minutes).
For more information about what encoders can and cannot do, please see the FAQ below.
All the included software is integrated into a single, easy-to-use, application consisting of TheSky™ Professional, TPoint™, Cameras+, Domes, Multi-OS+, and Weather modules.
You can control all your astrophotography-related cameras and devices with this one app.
It runs on macOS™, Windows™, Ubuntu™, and Linux (x86_64 and ARM64 architectures).
Regardless of the operating system you run it on, it appears and operates identically. You can even switch between operating systems and its license allows up to six computers. Why paint yourself or your institution into a corner?
Absent ProTrack™ which is unique to Paramount, the included software is sold separately as TheSky™ Universal Bundle and represents a US$1,095 value.

$10,749.00

The All NEW iOptron CEM120EC

An extraordinary innovation in mount design...Now with a new payload!

Recognizing the growing demand for an accurate and stable, equatorial mount with the versatility to carry larger instruments and more complex imaging arrays, we created the iOptron CEM120EC. It offers the benefits of our revolutionary “center balance” design: stability, accuracy, and smooth mechanical operation, while capable of carrying a payload up to 52 kg. The “center balance” design’s natural stability is due to its focusing the mount along with payloads weight directly over the center of the pier or tripod.

The CEM120EC's performance is demonstrated by its low periodic tracking error of <0.15 arcsec RMS. Along with the stability aspect, the CEM120EC features an advanced cable management system consisting of more ports in more locations preventing tangle ups and reducing the chance of fractured cables. It also adds some new features to the CEM family like Wi-Fi and LAN for remote operation and easy to use, reliable clutches on both axes.

Optional Extra's

Optional heavy duty Tri-Pier 360 and Permanent Pier are available for order.
