At our ZWO lab, we testing very new astro images processing software Astro Pixel Processor (APP). APP has many very interesting features and some of them are very unique. Many of our customers bought color DSO cameras and the very first step for all those users during image processing is choosing the right debayer algorithm.

In this short article, we compare two very popular cameras, ASI174 and ASI290. Particularly, we were testing the effect of the pixel size of each ASI camera. ASI174 has 5.86µm and ASI209 only 2.9µm of the pixel size. Why is pixel size so important? Camera with smaller pixel size adjusted at telescope with short focal

Astrography under a good astronomical seeing is the main desire for astronomers all around the world. Seeing is the most important factor for DSO or planetary image quality. Practically all professional observatories are located on locations with sub-second seeing, where seeing values are below 1 arcsec, but amateur astronomers are doing astrography under the sky where is the common seeing between 2

Martin captured Jupiter in RGB and CH4 with ASI224 camera attached on big 444-mm Dobson. What Martin said about this amazing photos? The methane image was taken during a period of good seeing with my home-built 444-mm Dobsonian working on my equatorial platform and at f18- a slightly shorter f-ratio than I would use for RGB imaging.

3 new ASI cameras has come: ASI224MC ASI185MC ASI178MC. This cameras have Low Noise, High Sensitivity and Fast Speed. These cameras are the best planetary imaging camera in the world and the cooled version won’t be far away 😉 For more info and orders please visit products pages.
