There are absolute QE charts from e2v. For sapphire EV76C560 QE max is around 60% - chart and chart 2.

Airylab should have their own measurements too.

Hey Guylain,

Might be too late to jump in, but I use a PST40 and Flea3 firewire. I image with Firecapture and get frame rates of around 120 fps using a Toshiba S105 S4114 laptop running XP SP3 32Bit with 4 Gb RAM and a hybrid HDD. I usually have to wait a few seconds for all the captured frames to write to the disk before starting the next capture (usually framing the next shot is enough) but it works well. I capture 30 second AVIs. Normally I shoot with a 2x barlow and mosaic my full disk images. You really need to make sure you have a 30-50% image overlap for this to work well.

I made an adapter for the Flea3 barrel by cutting down an old webcam adapter barrel and friction fitting it over the C-mount nose after wrapping it with some electrical tape. It works well. My normal adapter that threads onto the C-mount wouldn't allow me to reach focus without a barlow (too long). You can cut down an old eyepiece barrel too. Make it a little longer than the C-mount nose piece.

Good luck and enjoy the new toys!

Cheers

Hi gys

I use blackfly icx693 mono and for me it's the best for planeraty imaging ,in this years I try maebe all sensor (618,445,NIR,asi 120,asi224 ,EV2.....) but 693 have QE 81% in version USB3 ,low low noise like or better 618

click on imaging performance specification

https://www.ptgrey.c...ion-sony-icx693

In this day I write at Point Grey for info blackfly icx 445 mono,I do not understand why icx 445 on blackfly USB3 have QE 61% and on Chamaleon USB3 it's 68%

I use a ZWO 174mm, you need a mono camera for solar pictures. I take videos and I like the high FPS of the ZWO, with USB3 I get more than 200 FPS, stack the video in AS!2 and add color in Photoshop.

Point Grey makes separate measurements for every camera time. The QE results differ - either due to some equipment difference, different cover glass and so on. ICX693 and ICX692 are quite good CCDs, but not as fast as Sony CMOS. Average read noise is always higher (but uniform at least).
