Quantum efficiency is a crucial measure of a sensor’s sensitivity. The newly released QHY miniCAM8, featuring the IMX585 sensor, delivers exceptional QE performance. Quantum Efficiency Curve of miniCAM8 As shown in the image above, the miniCAM8M performs exceptionally well across various wavelengths, with strong quantum efficiency in the SII, Ha,

In scientific research and industrial applications, cooling capacity and dark current levels are crucial parameters for evaluating scientific-grade cameras. There are many factors contributing to dark current generation, but for optical sensors, temperature is the most significant. Higher temperatures result in greater dark current. Controlling temperature is essential for suppressing dark

A team of astronomy enthusiasts from China called SWONS (Super Wide-field [OIII] Narrowband Survey) discovered an astonishing [OIII] nebula in the winter sky. They made this discovery during their super wide field narrowband survey project in 2023. They named the target “Silk Nebula.” Silk Nebula in [OIII]+Ha This wide-field narrowband

The purpose of this paper is to conduct a series of tests, both on the bench and on real stars, to understand the behavior of the QHY268 Color version to evaluate its potential in terms of science observations for the amateur community. This camera has an APS-C sensor on a

  By Michael Barber For several decades monochrome CCDs were the sensor of choice for dedicated astro-imagers. Initially, CCDs were smaller in area than standard 35mm film frames but they were more sensitive and did not suffer from reciprocity failure, a common characteristic of film emulsions. However, CCDs were expensive and it took some time

QHYCCD: Hello Michael! We have followed you and your works for so long time, very happy to have this opportunity to learn more about you, a master of comet photography. Please feel free to share your story with us! First, please make a self-introduction for us. Michael: My interest in

Author: Michael Wong Review on QHY5III678M and QHY5III715C   The focal ratio that allows planetary imaging to achieve the optimal sampling rate is five times the camera pixel size in micrometers. In the past, camera pixel sizes were approximately around 3-5 micrometers, resulting in optimal focal ratios between 15-25. Even

Q: Really appreciate that we can have a chance to know more about you! Please make a brief self-introduction.

At the beginning of this post, I’ll share with you a first light of QHY268M: This picture of Rosette Nebula was imaged by Christoph Kaltseis, an excellent astrophotographer from Austria, with QHY268M+QHY462C. It is a nice work. Here is the interview for Christoph. QHYCCD: Congratulations on the first astronomical image

Northolt Branch Observatories are located in London, England, and have achieved many outstanding results in astronomical observations. At the same time, they are an important user of QHY astronomical cameras. In recent years, they have confirmed about 200 new-earth asteroids and conducted more than 6,500 measurements of small celestial bodies

Motivation: Spectrally Agile Flat Field Illuminator I have had an idea for many years to build and sell a spectrally agile flat field illuminator device. I thought about this since at SBIG we routinely encountered CCDs that had flat field variations that changed with wavelength by significant amounts. We saw
