Bigger diagonal fits more Sun. 1/1.8" diagonal of that sensor would fit the whole Sun from that Lunt, but barely - from edge to edge, so 2-panel mosaic only would be needed.

And it's faster than the ICX445 CCD.

Thanks for the info.

Decisions decisions...

Well, I do want to be able to fit the whole disk without mosaic. This is actually a hard requirement for me. I'll be using a 2.5x and/or 5.x televue power mate to increase resolution when I want to image the edge.

What about the Grasshopper GS2-GE-20S4M-C? It has a Sony ICX274 with a 1/1.8" diagonal (same diagonal size as the e2v CMOS BlackFly) with 1624x1224 resolution at 29 FPS.

Thank you for the information, I really appreciate it.

ICX274 is old and less sensitive. And 29 FPS isn't 60 FPS. You can find it on airylab QE chart They also do solar tests of various new sensors (including biggest at the moment 1" cmv4000 ).

To easily fit the whole Sun (no Barlows) you would need at least 2/3". 5x Powermate would be to much - pushing resolution much above scope resolving power.

Thank you PiotrM

Don, I have signed up on your web site to receive information in the Blackfly. My interest has now shifted to the Blackfly BFLY-PGE-13E4M-CS which should be available Q4 2012... any time now i guess.

Hi Guylain,

The QE on the Blackfly's are not ready yet since the sensor guys are still tuning the sensor timing and trying to optimize the performance. But the e2v information should be ready first and since you are registered to get information updates, you should know about the same time I do

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
