A good guide about the advantages of image stacking for DSLR astrophotography    The benefits of adding more subs to your stack Adding multiple exposures to create a single image is one of the key elements of doing astrophotography. It enables us to get rid of bad pixels, satellite trails, noise while increasing signal to…

It’s a hot, rainy Saturday afternoon in Sydney so what the hell, there’s an old pic of M31 I took some time ago. 

This s very cool! Sony has just announced a CMOS chip that can read all the pixels at once – plus is has  large 3 micron pixel size which will see it became a favourite for planetary imaging I’m sure! Sony has made something of a break-through in sensor development with a new backside-illuminated CMOS…

  CCD vs CMOS | Teledyne DALSA Another interesting read on CCD vs CMOS Much has been written about the relative advantages of CMOS versus CCD imagers. It seems that the debate has continued on for as long as most people can remember with no definitive conclusion in sight. It is not surprising that a…

A good read on colour vs mono astronomy cameras Should You Get a Colour or Monochrome Camera? • PhotographingSpace.com Why on earth would you ever choose a monochrome camera for astrophotography when there is so much beautiful color in the universe?!

Good background on on Sony Exmor sensors, especially the GSTAR-EX3 used in astronomy cameras like the  GSTAR-EX3 or  Hypercam IMX178   What is Sony’s Exmor Technology Anyway? A personal CMOS tutorial by FRAMOS’ Darren Bessette I was just as surprised as all of you were when I heard the news that Sony is discontinuing their CCD line…

Very detailed article about the differences between CMOS and CCD cameras.    Comparison of CMOS and CCD in the field of spectrography For spectrographic applications in particular, I compare the performance of Charge-Coupled Device (CCD) sensor with the latest generation of Complementary Metal Oxide Semiconductor (CMOS) sensors available to amateurs at the date (August 2017).…
