QHY600 BSI Cooled Cameras

The QHY 600 is available in three models: The QHY 600 PH-L (LITE) (only available with monochrome sensor), the QHY 600 - PH (PHOTO) and the QHY 600 - PRO. The last two models are available with either a monochrome or a color sensor. The image quality is identical for all 3 models.

The PRO version can optionally (at extra cost) be delivered with 2 x 10 Gigabit fiber interfaces and a PCIE Crabber Card (#1931167, € 1275,-) for faster data download. This option is not available for the LITE and PH version.

The monochrome QHY 600 M models PRO and PHOTO are delivered with an Industrial (Grade K) class sensor. This sensor is certified by Sony for 24/7 continuous operation. The QHY 600 PH-L is shipped with a Consumer (Grade C) class sensor and is not designed for 24/7 continuous operation. Here we describe in detail the differences between the Industrial and Consumer sensor classes.

The models with the sensors of the Industry class are recommended for professional astronomy and semi-professional amateur astronomy in remote operation for regular sky monitoring.

Special versions of the QHY 600:

All three models (PRO, PH and LITE) are also available as short backfocus (BFL) versions. Here the backfocus is only 7mm, instead of the usual 17.5mm, behind the camera body. The QHY600 Short back-focus version is specially designed for DSLR lens users or those who has special requirment of short back focal length. An OffAxis Guider and filter wheels can be integrated. For more information on the BFL, please visit the QHYCCD manufacturer's page and our "New Technologies in the QHY600 and QHY268 Cameras" page.

The QHY 600 PRO versions (mono and color) are also available with liquid cooling for an additional charge. Liquid cooling has several advantages over air cooling and cools deeper below ambient temperature than standard air cooling. The liquid cooling for the QHY 600 - PRO must be firmly ordered with an order, a later retrofit is NOT possible. Further information about water cooling we describe here

The QHY 600 PRO versions (Mono and Colour) can be equipped with 2 x 10 Gigabit fiber interfaces for an additional charge. This requires an additional PCIE interface board from QHY: PCIE Crabber Card (#1931167, € 1275,-) . The Gigabit interface is an upgrade and can be ordered directly when placing an order, but can also be activated at any time later. More information about the Gigabit interfaces can be found here

Important note: For all orders of QHY 600 special versions we kindly ask you to contact us via eMail to avoid any mistakes.

High Resolution, 61 Megapixels, Full Frame

The QHY600 Mono versions (PH, PRO, Lite) uses the new Sony Full Frame (35mm format) IMX455 Back-Illuminated CMOS Sensor. It is available in both a monochrome version and a color version (PH, Pro). The IMX455 is a 61 Megapixel, scientific CMOS sensor with 3.76um square pixels and 16-bit ADC. The sensor size is 36mm x 24mm. All Mono version of QHY600PH & QHY600Pro use IMX455 industry grade sensor (Grade-K). A consumer sensor with Grade C is installed in all color versions. This sensor is certified by Sony for 24/7 continuous operation. The QHY 600M PH-L (LITE) is delivered with a consumer (Grade C) class sensor and is not designed for continuous operation.

Full Well Capacity, >51ke- at 3.76um, >400ke- Binned and up to >720ke- in Extended Mode

One benefit of the back-illuminated CMOS structure is improved full well capacity. This is particularly helpful for sensors with small pixels. Even with unbinned 3.76um pixels the QHY600 has a full well capacity >51ke-. When binned 2x2 to 7.5um the full well is >204ke- and when binned 3x3 to 11um the full well is >408ke-. In extended mode the full well is >80ke- unbinned, >320ke- binned 2x2 and >720ke- binned 3x3.

Native 16-bit ADC

With native 16-bit A/D on-chip, the output is real 16-bits with 65536 levels. A 16-bit ADC has a higher sample resolution than 12-bit or 14-bit ADC and the system gain will be less than 1e-/ADU. The QHY600 uses software digital binning. With digital summing, 2x2 binning will be four 16-bit summed = 18-bits.

Breakthrough Low Read Noise 1e- to 3.7e-

The QHY600 is capable of only one electron of read noise at high gain and 2 FPS high readout speed. One electron of read noise means the camera can achieve a SNR>3 at only 3 to 4 photons. This is perfect performance when conditions are photon limited, i.e., short exposures, narrow band imaging, etc., making this large area sensor ideal for sky surveys and time domain astronomy.

Back-Illuminated, >87% QE, Low Dark Current

Sony's Exmor R back-illuminated technology produces sensors that Sony estimates are twice as sensitive as similar front illuminated sensors. QHYCCD tests have borne out this claim and based on our tests the peak QE is greater than 87%. Additionally, Sony sensors are well known for their low dark current. QHYCCD's proprietary thermal noise reduction technology and the QHY600's dual-stage regulated thermoelectric cooling further reduce dark current to extremely low levels, 0.0032e-/p/s at -20C for clean, long duration exposures.

Best Match for RASA System

The round camera case design of QHY600 and the high resolution, large area, small pixel array is an ideal match for RASA optical systems.

Readout Mode Selection is a new function for the QHY600 and other newer QHYCCD cameras. Different readout modes have different driver timing, etc., that cause the sensor to yield different performance results, allowing you to tailor the sensor response to your particular imaging needs. Each readout mode has its advantages and disadvantages. The QHY600 currently has three readout modes. In the future QHYCCD may add more modes.

Readout Mode #0 (Photographic Mode). In this mode, the read noise of the QHY600 drops between a gain setting of 25 and 26. We therefore recommend setting the gain to 26 as a starting point. At gain=26, the full well is 27ke- and read noise is 2.7e-. For long exposures where read noise performance is not as critical, lowering the gain results in higher full well.

Readout Mode #2 (Extended Full Well Mode). In this Ultra-High Full Well Mode, the QHY600 exhibits an unbinned full well capacity of greater than 80,000e-. Binned 2x2 the full well is greater than 320,000e- and binned 3x3 the full well is greater than 720,000e-.

New readout mode # 03:

QHYCCD extends the readout modes of the QHY 600 models by the new # 03 Extend Fullwell 2CMSIT mode. The advantage of mode # 03 is that it has the same fullwell value and system gain as mode #02 Extend Fullwell, but the readout noise is reduced by about 1.3 times. This readout mode may require upgrading the control software to version SDK (Software Development Kit) 2020.6.26 or later. If your software does not display mode # 03, please download the QHY All In One installation package to upgrade the SDK in the software. The mode is available for all QHY 600 series models.

QHY600 Readout Noise all mode

This readout mode requires an upgrade of the control software to version SDK (Software Development Kit) 2020.6.26 or later. If your software does not show mode # 03, please download the QHY AllInOne installation package to upgrade the SDK in the software. The mode is available for all models of the QHY 600 series.


Quantum Efficiency.
Sony provides a relative QE curve for the IMX455 sensor. in order to determine the absolute QE of this curve QHYCCD ran tests comparing the response of the IMX455 sensor against a camera of known absolute QE at two wavelengths along this curve (489nm and 656nm). From these test results we can plot a good estimate of the QHY600 QE curve in absolute terms with a peak QE >87%:


Dark Current.
Dark current results for the QHY600 are based on measurements of the dark current of the IMX455 sensor installed in the QHY600 camera. At 0C the dark current is 0.014e-/p/s and at -20C it is 0.003e-/p/s:

NGC1499 - BiColor aus UNB f2 H-alpha und UNB f2 SII
Die Kombination, RASA 11 + UFC + QHY600M auf der CGX + StarAID ist eine sehr gute Wahl für Deep Sky Abenteuer .
In nur 114min mit der QHY600M (Bin1x1) waren die Daten gewonnen. Die Kamera + RASA 11 sind wirklich genial!
Mit den Baader f2 Highspeed UNB Filter konnte ich die Daten auch bei Halbmond aufnehmen. Belichtet in Ha und SII 180sec für das Einzelbild....
  • Super Leistung und extrem viele Möglichkeiten mit dem System

First Light mit der QHY600 L, BSI Cooled Kamera
Man kann nicht in Worte fassen, was diese Kamera leistet. Ich habe schon einige Kameras in meinem Hobbyleben mein eigen nennen dürfen, aber diese QHY 600 L (Consumer Chip) ist überragend! Ich bitte um Verständnis, da ich
1. S/W Fotos liebe obwohl die meisten in Farbe (auch Hubble-Palette) fotografieren,
2. Ich kein Superexperte in der Fotonachbearbeitung bin (ja, ich ärgere mich nicht mehr über div. Farbstiche in Fotos die in unserem Lichtverseuchten Breiten herrschen) und ich nicht nach Spanien, Italien oder LaPalma fahren/fliegen muss, sondern alles von zu Hause (zwischen Frankfurt und Bad Camberg) machen kann, sogar ferngesteuert vom Sofa im Wohnzimmer aus mit einem Eagle 2,
3. Es die einfachste und schnellste Fotonachbearbeitung meines Lebens gewesen ist!!!
Was will man mehr?
Aufnahme 07.11.2020, Heart Nebula IC 1805, QHY 600 L mit Consumer Chip (gesteuert über N.I.N.A.-Software - Die beste Software überhaupt für die Steuerung des Equipement), CFF 92mm f/6 + Flattner, Avalon M-Uno, Baader 7nm H-alpha 2" mit Baader UFC, 36 x 600sek., -10 C, Extended Mode 16bit, Binning 1 x 1, Gain 56, Offset 50, USB-Traffic 50 (Standard), 25 x Darks, 50 x Flats, kein Bias (unnötig), Fitswork, Regim, PixInsight, Adobe Photoshop CS6

Super Kamera mit extrem hoher Empfindlichkeit
Wie jeder Hobby-Astronom habe auch ich mal klein angefangen. Nach langjähriger reiner Beobachtung war mir eines Tages klar, dass ich das Ganze auch auf Foto festhalten möchte, so kam ich von der analogen Fotografie (Minolta Spiegelreflexkamera) zu einer digitalen DSLR-Kamera (Canon 400D).

Im Laufe der Zeit habe ich von verschiedenen DSLRs auf eine CCD-Kamera umgeschwenkt; diese CCD-Kamera von der Marke FLI mit dem berühmten KAF8300-Chip begleitete mich einige Jahre und machte hervorragende Bilder. Da CCD-Kameras im Laufe der Zeit zum sog. alten Eisen gehörten, musste eine neue Technik her:
Die CMOS-Kameras versprachen eine unglaubliche Empfindlichkeit und gutes Preis-Leistungsverhältnis. Ich kaufte für damalige Zeiten sehr gute Kameras von diversen Herstellern; eine monochrome und eine Farbkamera. Die monochrome Kamera hatte das Verstärkerglühen und die Farbkamera wurde nur einmal benützt und dann zum Hersteller zurückgeschickt. Leider habe ich diese Kamera bis jetzt noch nicht zurückbekommen, weil der "Fehler" nicht gefunden werden kann.

Nach ca. 2,5 Jahren Verstärkerglühen und "defekten Farb-Chip" hatte ich die Nase voll. Jetzt musste was richtiges gutes her, also rief ich Christoph Kaltseis an und erklärte ihm mein Problem. Da er mir von einer "richtig" guten, empfindlichen Kamera erzählte, musste ich zuerst mal einige Tage darüber schlafen, da es doch eine große Investition darstellte.

Dann schlug ich zu und bestellte über Christoph Kaltseis diese sagenumwobene Kamera Namens QHYCCD 600M EB. Nach 14 Tagen kam das gute Stück bei mir an. Am Wochenende baute ich die QHY600M EB-Version zusammen und war tierisch gespannt, welche Ergebnisse die Empfindlichkeit der Kamera liefert.

Wie es immer so ist, wenn man sich was neues zulegt, spielte das Wetter natürlich nicht mit, es regnete einige Tage. 14 Tage danach wurde das Wetter besser und ich konnte die Kamera endlich ausprobieren. Vorher habe ich die ganze Software und Treiber geladen. Ich freute mich wie ein kleines Kind an Weihnachten.

Es ist ca. 21:30 Uhr und es ist fast dunkel. Gespannt schloss ich die Kamera an und ..... puuhhh. Kamera wurde nicht gefunden! Was habe ich falsch gemacht. Ich kontaktierte sofort Christoph Kaltseis - der mir prompt half. Alles wieder deinstallieren. Zuerst den einen Treiber (Kamera), dann ASCOM- und Filterrad-Treiber installieren. Leider funktionierte es trotzdem nicht. Fehlersuche!. Am nächsten Tag war das Wetter noch super gut. Da ich Urlaub hatte, suchte ich den Fehler. Als ich nach ca. 5 Stunden Fehlersuche endlich auf einen Laptop installierte, funktionierte es tadellos.

Am Abend endlich super Bedingungen. Ich schaltete die Kamera ein und .... siehe da, es funktionierte. Gleich mal auf den Stern HIP 102707 nähe NGC6960 gegangen und mal 30 Sekunden laufen lassen (siehe Bild).

Wowww, bin begeistert. Mit dieser Empfindlichkeit hätte ich nicht gerechnet. Diese Kamera ist zwar nicht günstig, aber empfindlich ohne Ende. Nach dieser Test-Aufnahme ging ich zu M27. Die Aufnahme von M27 wurde nur mit 30 Sekunden belichtet, je 20 Bilder davon (LRGB). Mit PixInsight bearbeitet und mit Photoshop vollendet.

Dank an Christoph Kaltseis und dem Baader-Team, mit denen ich immer noch in engem Kontakt stehe: Ihr habt mir wirklich nicht zu viel versprochen.

Zusammenfassend ist zu sagen, dass die QHYCCD 600M EB eine super Kamera mit extrem hoher Empfindlichkeit ist, die diese Investition durchaus wert war und ihren Preis rechtfertigte.

Viele Grüße,
Hans Schäffler
