Many thanks for these first images of the new baby. Seems promising.

But there's something I don't understand : is it USB 2.0 or USB 3.0 port on camera ?
For multipurpose use, only USB 3.0 is interesting.

Please, could you post us a picture of the back of the camera ?

Many thanks.
Best.

I'll post pictures later but the camera itself is USB 3.0 and it has 2 USB 2.0 inputs for accessories. I haven't used them.

Thanks for the feedback. Any idea of the backfocus ?

Frédéric.


Thank you. If I remember right the backfocus is 17 mm but we have to check with Sam to be sure.

Wow. At unity, that thing still has over 12 stops of DR.

The front plate on the camera looks like a tilt plate. Is it adjustable for tilt?

You are right I forgot to mention this. It is adjustable

Is that just ZWO's tilt adapter? Or does that come with the camera?

No it's not an additional part. It's part of the camera's front face. It's a simple pull push collimation adjustment. I have't touch it on the test camera. After I seated the camera in the focuser properly, I did not see a tilt.

Hmm, interesting. Is the tilt adjustment part removable for shorter backfocus, or is it fixed at 17.5mm?

I am not sure. I don't think it's removable. I mean you can probably remove it but the threads are on this part. I'll ask Sam about this to be sure.

Sam did not give me an exact number when I asked. I would hate to give a wrong figure. I don't think it's set yet.

Hmm. I wonder if it would be an option on the camera. I really like the ability to get down to 6.5mm backfocus. While tilt adjustment would be nice in some cases, in others (i.e. use with a camera lens) it makes getting the necessary backfocus very difficult.

I think it was necessary for the heater. What would be the benefit of having 6 mm BF for a color camera? There is going to be a Canon adapter for this. In fact it will be here tomorrow. I will be testing with a Samyang 135.

Oh, I'm just speculating about future ZWO cameras that might incorporate the tilt adjuster. :p I fully expect to be buying another ZWO camera in the probably not so distant future. I want a larger mono camera if they make one. However, integration of the tilt adjuster, while I'd love it (as I've certainly had my fair share of problems with tilt), would probably make using such a hypothetical camera with my camera lenses & a FW a non-option.

Hi Tolga

 

Is there a QE graph for this sensor?

I don't think the data is available. I'm still trying to get you an answer.

tolgagumus,

 

I haven't noticed any discussion of amp glow.  Have you seen any with this camera?

This sensor is used in the Nikon D7000.  On the Sensorgen site, they have the QE listed for the D7000 at about 50%.  That's pretty good for an OSC chip with the Bayer filter array in place.  The Canon T3i I'm currently using is listed at 40%.

Thanks Dan.

 

If it is available, the QE graph would be more useful since it will show the QE across the sensor.

I haven't noticed any yet but I also haven't tried anything over 4 minutes with it either. I'm going to do some 5 and 10 minute darks to see. I don't see a reason for doing more than 10 minutes since it's a color camera. I'm doing some test shots with it tonight using the Samyang 135 F/2 stopped 2/3.
