QHYCCD’s New QHY461-PH: Ideal Successor to KAF-16803 Based Cameras

  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

Unveiling the QHY5III715C and QHY5III678M: Test and Impressions

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

【User interview】The First Interview of QHY268M Users

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

Space Exploration of Northolt Branch Obs

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

Testing the QHY600M for Spectral Flatness by Alan Holmes, PhD

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
