QHY8 detail information

Sony's high performance CCD

It is a Diagonal 28.4mm(Typic 1.8inch)CCD with a 7.8um*7.8um square pixel array and 6.15Mega effective pixels.Suitable for both big and small telescopes

High sensitivity and very low dark current are achieved through the adoption of Super HAD CCD techonology.

R,G,B primary color mosaic filters on chip to build the vivid color image,one shot color.

Excellent anti-blooming characteristic make the stars avoid the blooming even star is very bright and at long exposure time.

Progressive scan mode ,do not need mechanical shutter

High Ha senstivity(QE=50%) allows using narrow band Ha filter for Ha nebula imaging.

High performance,multi-function electric design with USB2.0 high data transfer rate.

Double Correlated Sample allow the ultra low kTC noise and product a very smooth image output.

Ultra low noise Preamp Readout noise is 8-12e-

Programme Gain Amplifier with analog and digital stage make freely for gain control by users.

16bit AD sample can reach 65535 grayscale level.

Long exposure setup,Adjust freely at step of 1ms

High transfer data rate with USB2.0 High speed. Normal download is 600kpixels/s,Fast preview download is 6Mpixels/s allow live video focus,download whole 6mpixel within about 1sec.

Two stage TEC makes very long exposure little hot noise

Camera come with Free Astrowin and MaximDL plugin

Full function Software on WINDOWS98.2000,XP

adjustable exposure time:1/1000 to 10000 seconds, adjustable analog gain control: 0 to 13 dB

Center area Preview for fast focus mode(Subframe supported in MaximDL plugin)

16bit FITs,color TIFF and 8bit bmp format

CCDSOFT, AstroArt, CCDCAP software supported

Nebulosity software supported

M42/0.75 standard Screw allow all kinds of adapter.

40mm large IR filter and AR optic glass window available

Self desiccation design prevent CCD get ice.Do not need silicon gel.

The 1.25 inch Standard eyepiece interface can connet the telescope directly

M20 By Mr.Ken with his homemade 18inch Newton+multipurpose coma corrector and a baader uhcs filter, 6 x 400secs and 1 x 400 sec darks. The APS size and 7.8um pixel allows camera works in very big telescope

Gamma nebula area by Mr.Randy.Single 2hours exposure with Tak Epsilon 130 F3.3 and 9nm Ha narrow band filter.Shows the good dark noise controlling with Super HAD and two stage TEC
