Hello,

 

I received this week my Nikon Z6 modified by Central DS.

I am very happy with the result.

 

First test done last friday on NGC2238.

The Z6 has by far a better ergonomy than my 7s.

The zoom level for focusing is far better as well.

 

The central DS filter system is fine. I used a L-Pro.

Cooling +fan power is done with a 5V USB cable.

It drained in 2h30 half of a 20000mha 5v battery used at the same time with the lens heater. It was 1° outside.

 

The picture was done with a Crux 170 HD mount, no guiding, no pec.

So stars were not dead round and I did a 20% reduction.

The link to the stacked dark (25 darks done at -13° on the sensor):

A raw file :

The streched stacked dark histogram reveals fine bands. I don't know why it is not homogenous.

I shoot with electronic shutter. Is there a link ?

Hope that's help :-)

Congratulations on your Central DS modified Nikon Z6!

 

The stripes in the dark are caused by the PDAF banding, not by the electronic shutter.

You can see more about this on my Z6 Testing thread:   https://www.cloudyni...kon-z6-testing/

Unfortunately the stripes don't calibrate out of images, so you need to dither.

 

When comparing my Z6 to my A7S one thing I really miss is framing my shots in the ISO 102400 4 frames/sec video mode.

 

Mark

Thanks Mark for the information and clarificaton.

I understand now I missunderstood this point in your tread :-)

 

Yes, such video mode is missing.
