« on: September 02, 2008, 01:04:43 AM »
QHY9 use KAF8300 mono sensor with mircolens.

To compare the KAI4021 , KAF8300 has better QE(QE=48%)  in H-alpha

KAF8300 is a 4/3inch  8.6mega pixel size CCD sensor. The pixel size is 5.4um*5.4um.  At 2*2bin mode it gives a 10.8um*10.8um   2.15mega pixel output

With improved heat sink design and a specially designed 2-stage TEC, QHY9 can reach maxium -50degree temperature difference from ambinet. The TEC power consumpt reduced to only 20Watt(less than 12V2A,at the maxium PWM)    There is a build in temperture sensor and a 16bit ADC for this sensor.  With new DC103 powersupply the tempeture is fully loop controlled.

QHY9 is fully airproof. With two air socket (4.0mm standard).

Lovely! Can't wait to see some long duration raw dark frames. One of 5, 10 and 20 minutes perhaps? The extreme cooling should help keep noise and dark current under control but I have to admit I'd be worried about using a Kodak sensor after being spoiled with the Sony in the '8.

Does this camera do internal buffering of the read-out data so that transfers can be made error free even with USB congestion?

Congrats on reaching this important milestone!
All the best,

Hello,

           I will do the dark frame test very soon. Maybe this week I will have changce to go to dark site to do some real capture.
This camera has 32MBytes SDRAM buffer so it do not have any problem of the USB pause. With this big buffer you can even do image stacking
when capture the continous images.

Sounds great! I'm happy with the '8 so far but at some point I'll want a monochrome camera I'm sure :)
All the best,

 ;D I want a QHY9 for my new Tak FSQ-85 NOW  ;)

The smal pixels will be perfect for it's 450mm focal lenght.

Kind regards
Jacob

Hello,

     The weight of the QHY9 is 510g, the connector is the M42/0.75 screw. It works with our 40mm optic windows for QHY8(M42 to M42) The outer side is just 2inch.

Hi QiuHY,

I understood, that you will use the same optical window as in QHY8 to seal the
chamber?
I'm somehow worried about optical windows thickness.
We who have a very limited amount of back focus might not be able to focus this system.
Can there be a "slim line" version of the optical window for the QHY9?

What is the total distance from the CCD to the front surfage of the optical window ring?

Hello,

         I think there is no big problems. The QHY9 CCD to surface is about 8mm .This is only 1-2mm more than QHY8.

I´m in the " waiting "  list for a QHY9 in Spain.I´ll purchase one RIGHT NOW (well..when the QHY9 be launch to the Spanish Market  :D )
WISHING to use it ¡¡

Thanks for great product Qiu..Now..the filterwheel you´re developing is essential for a monochrome camera. Do you have a final production date for this filter wheel ?

I use 50mm UNMOUNTED  filters for narrowband..Will have the filterwheel 50mm filter capabilities ?..

Best regards ¡
