Lack of a trusty USB3.1 Hub in astrophotography market triggered Pegasus to develop a USB3 Hub controller which will be also able to switch ON/OFF each USB port.

A SuperSpeed (SS), low power, switchable USB3.1 Gen1 hub and fully compliant with USB-IF’s USB 3.1 Gen1 specification . The Hub supports Hi-Speed (HS), Full Speed (FS) and Low Speed (LS). The new SuperSpeed hubs operate in parallel with the USB 2.0 controller, so 5 Gbps SuperSpeed data transfers are not affected by slower USB 2.0 traffic.

6 x USB3.1 Active Ports

Device has 6 x USB 3.1 Ports. All ports are backwards compatible with USB 1.0 and USB 2.0 devices. Moreover, each port can deliver up to 2.5Amps of current. There is a smart current limit sensor in every port which automatically limits or cuts power in case of a short-wire or power consumption that is above 2.5Amps. Each port is monitored by the USB Controller and in case of a current limit, it triggers a warning popup in the operating system.

Aluminium Enclosure

A high quality robust, blue anodised aluminium enclosure houses the electronics of the USB Hub. The metal enclosure designed and tested to survive ±5kV ESD strikes

Switchable USB Ports

Each USB port can be controlled and switched ON/OFF by our standalone software. (power + data). You are going to love this feature. No more pull out and re-plug USB cables of your equipment.

12V DC Operation

The 12V DC operation was our first design requirement. As most of your astro-equipment work with 12V DC why to use something different?

Hub accepts 12-14V of operation. This means that you can plug unregulated 12V power from a battery.

Industrial grade temperature support 

Most USB Hubs in the market (well…nearly all of them) operate under room temperatures as they were design to work inside your cosy warm room. This is one of the reasons why you experience USB disconnects and instability during a cold night.

Our product is certified to work flawlessly from −40°C to +85°C. All USB Hub electronics has been selected to support Industrial grade temperature ranges.

Pegasus Astro – Falcon Rotator is a light-weight, low profile camera field rotator. Do not be fooled by its thin size. It can lift and handle heavy image trains easily. It is very easy to operate via ASCOM drivers or standalone software.

Low profile / M54 threaded

Thickness of the rotator is 18mm / 0.7”.

When you use the M54 to M48 adapter the backfocus is +1mm (18+1 = 19mm)
Weight is 700grams. Both openings of the rotator are M54 threaded (pitch 0.75mm)

Adapters for both sides (included)

We provide two different adapters for both sides:

• Telescope Side: M54 male to 2” Nosepiece
• Camera Side: M54 Male to M48 Male Adapter

Important notice: The M54 adapter black ring on the camera side of the Falcon Rotator sticks out by almost 1mm (so actual back-focus is 18+1 =19mm)

 

Precise rotation

A powerful geared / low backlash stepper motor ensures that the rotator will lock to the designated degrees. Mechanics inside the focuser guarantee zero flex in any point during a full circle rotation.

Aurora Flatfield Panels

Enjoy the perfect flat and say hello to a new era in electroluminescence flat field science with the revolutionary Aurora light panel.

The new Aurora Flatfield Panel is an advancement in the well known technology of EF flat field foils. Taking into account the huge demand from all over the world, this new product line was especially designed to match the needs of astrophotography. The Aurora Flatfield Panel is a new light source technology for taking flat field images for use in calibration with digital images. It consists of a thin electroluminescent foil which emits an even, gentle white light after an external voltage is applied to it.  For more technical explanation on electroluminescence, please refer to the Wikipedia page about Electroluminescence.

Some benefits of the Aurora Flatfield Panel over other flat field light devices

An evenly illuminated surface

A broad, continuous spectrum which may be used with emission line filters 

Lightweight and easy to handle inverter for 12V and 110/240V available - suited to both stationary and mobile use. 

Description

The Aurora Flatfield Panels are mounted in a rigid frame consisting of virtually unbreakable plastic with an extra protection around the edge so your Aurora is very well protected during transport and travel. The opaque front plate gives you a more uniform brightness than the EL material alone. For very fast optical systems, you will likely need to reduce the brightness by placing some sheets of paper in front of the EL sheet and the frame of the Aurora will keep them secure.

Sizes

The Aurora’s are round in shape – perfect for telescope tubes and the diameters are matched to fit the popular sizes of amateur telescopes. The following sizes are available:

D 100mm (for Instruments up to 4")

D 160mm (for Instruments up to 6")

D 220mm (for Instruments up to 8")

D 315mm (for Instruments up to 12")

D 420mm (for Instruments up to 16")

Larger Aurora Flatfield Panels up to 60cm are possible upon request. Special custom made foils up to 1.1m diameter are possible also. (Upon special request, please send us an email)

Selecting the right size for your setup

To get high quality flat field data you have to select the right size of Aurora. The clear diameter of your instrument has to be fully covered. The diameter of the dew sheild is not important,

Example: For a 6" (15cm) refractor a 160mm Aurora is the right choice, no matter if the dew shield is larger, but you will have to make sure that the Aurora is precisely centred on the scope.

If you use a Newtonian, Cassegrain, RC, ODK or similar, the Aurora has to be LARGER than the clear diameter of the optic. As a rule of thumb, the Aurora has to cover the clear diameter of the mirror plus the diagonal of the sensor used inside your camera.

Example: If you use a 8" (204mm) Newtonian telescope, the 220 Aurora is sufficient if you have a camera with a quite small sensor (<14mm diagonal). If you use a typical DSLR with an ASP-C sized sensor you will have to select an Aurora one size larger.

It is no problem using a large Aurora with a small telescope. If you do have a 315mm Aurora it will work fine with a 4" refractor or a camera lens

Colour

The light emanating from the Aurora Flatfield Panels is slightly bluish-white. Most panels from other suppliers seem to provide pure white light (as perceived by the human eye) but the light is in fact made of discrete emission lines. Due to this, the flat field EL panels from most other suppliers are not suitable for narrowband emission line filters. We have tested the products of all EL sheet manufacturers worldwide and selected these particular EL foils for our Aurora Flatfield Panels because they are the best for astronomical applications. The spectrum of the Aurora Flatfield Panels is not made of some emission lines. Intstead, the EL material used in the Aurora Flatfield Panel has a very broad, continuous emission across the whole spectrum. This fact is what makes our Aurora Flatfield Panels great for narrowband emission line filters. The three spectra below illustrate the difference between our continuous spectrum EL panels and typical EL panels with light generated with discrete emission lines present.

Spectrum of a bad foil (but still looks white the the human eye!)

Spectrum of a good foil (EF Foil)

Spectrum of a Aurora foil (perfect!)

You can see the very broad emission of the new Aurora Flatfield Panel which is very well suited for the work with DSLR and cooled CCD cameras, working with broadband or RGB filters and for work with narrow band emission line filters as well..

Brightness

The brightness of the Aurora Flatfield Panel is matched to work best with typical light intensity levels produced after passing through filters. If you are working with light from the whole spectrum, such as when using no filter or only a UV+IR blocked Luminance filter, you will likely have to the reduce the brightness of the panel. The brightness can be controlled electronically to some extent by reducing the input voltage of the inverter (12V inverter only). If the panel is still too bright for your setup, as may be the case with fast instruments and/or very light sensitive cameras, you should consider putting one or more sheets of paper into the frame between the layer of white plexi-glass and the EL material. For very fast optical systems and/or large cameras with slow shutters, the brightness of the Aurora has to be reduced effectively. To that end,  we offer neutral density / grey filters foils in corresponding sizes to be placed inside the frame of the Aurora panels. For customers with fast Astrographs and/or very sensitive cameras we do recommend getting one or two of the foils. The brightness is very even across the whole surface and it works well for the most critical imaging applications, even photometry or spectroscopy (see application links above).

Power

The Aurora Flatfield Panels packages include a compatible inverter. (Standard AC adaptors won't work.) The panel is illuminated by the external high voltage produced by the inverter. This high voltage, however, is produced at very low amperage, so there is no  risk of electric shock.

IMPORTANT: Please use the Aurora Flatfield Panels with the supplied matching inverter only. Connecting a panel to an inverter of the wrong size reduces the lifetime of the unit. There are 12V inverters for all sizes of Aurora Flatfield Panels and for the large size units there are also 110/230V inverters available.

Astrograph supply the 100mm Aurora with an inverter terminated with a 2.1mm DC Socket. This allows you to power the panel from DC battery / power packs as commonly used with mounts etc.

What you get

Your Aurora Flatfield Panel is shipped as a ready-to-use set consisting of the mounted EL substrate, the matching inverter, all cables and a printed manual.

LPR Foil for Aurora Flat Field Panels

For the Aurora 100mm and 160mm panels we offer this conversion filter for Aurora flatfield-devices.

To be used when light pollution filters like the Astronomik CLS, CLS-CCD or Optolong L-Pro are used for imaging.

When taking flatfield data with an Aurora you may notice that the histogram can look strange: The peak of the red channel can be on the left, while blue and green are on the right. This can make the flatfield data difficult to process.

The LPR Conversion filter makes processing easier as the Histogram is boarder and the channels are closer together.

We recommend this filter if you use a light pollution filter. If ordered with an Aurora we will fit it and any ND foils at the same time.

ND Foil for Aurora Flat Field Panels

To obtain the correct brightness level from the Aurora flat field with certain telescopes it may be necessary to add a neutral density foil. This will reduce the light level from the panel to a point where the correct flat field can be obtained. Foils of different values can be combined.

Our recommendation is that telescopes with a focal ratio of approx F6 will require an ND1.2 foil. For telescopes with a focal ratio of F4 then we suggest adding an ND0.9 to the ND1.2.

If foils are ordered with an Aurora Flat Field, then we will fit the foil to the filter before delivery. If this is not required, please notify us.
