Unfortunately no :-( I've tried to save the profile through those indi controls tabs but with no luck. 

I think that you can edit the file /home/stellarmate/.indi/Toupcam ATR3CMOS09000KPA_config.xml

 

And set the following lines at the end of the files like this:

 

<newSwitchVector device='Toupcam ATR3CMOS09000KPA' name='CCD_VIDEO_FORMAT'>
  <oneSwitch name='TC_VIDEO_COLOR_RGB'>
      Off
  </oneSwitch>
  <oneSwitch name='TC_VIDEO_COLOR_RAW'>
      On
  </oneSwitch>
</newSwitchVector>

 

Is one difference I found between the default and the present config file

 

The default file has this lines:

 

</newSwitchVector>
<newSwitchVector device='Toupcam ATR3CMOS09000KPA' name='CCD_VIDEO_FORMAT'>
  <oneSwitch name='TC_VIDEO_COLOR_RGB'>
      On
  </oneSwitch>
  <oneSwitch name='TC_VIDEO_COLOR_RAW'>
      Off
  </oneSwitch>
</newSwitchVector>

 

 

*EDIT*

 

The path shown above is for Stellarmate. The correct file location for Astroberry is /home/astroberry/.indi

 

In File Manager you have to right-click and select "Show hidden" to see the .indi folder.

 

I was able to make the RAW setting permanent by disconnecting form the control panel without saving. If I save it reverts to RGB.

This is not something specific with the 533, but this is my first cooled camera, so I am super excited for 🥳

Now I understand how important is the cooling system for all that noise...

 

PS. This could be useful for anyone that is not sure if he wants to take the leap to a cooled camera 😜

Great improvement, congratulations.

Does that 2" M48 to T2 adapter provide correct distance camera to the flattener (55mm). If the camera flange distance is 17.5mm, then the 2" nose should be 37.5mm thick. If it isn't then it must be found somewhere else or machined. My setup is ES127 ED APO, Skywatcher 0.85x flattener/reducer for ED100 and Canon EOS 500D. In the next few months I am planning to buy this Omegon camera.

I could only confirm that works ok with my specific setup. I do not have a flattener :-(

 

You can take a look on this thread here that I have some photos. If I could help you somehow, do not hesitate to ask.

I'm looking at both the 16000 (old sensor) and the 533. I like the bigger size of the 16k. But newer sensor is better. I don't know.

To combat cold hardware. I have it in a box with towels and warm water smile.gif

 

 

Thanks for sharing. Currently it is the 533 i'm looking at. The big question is if will be the zwo or omegon. It is quite a pricejump

Which is waterproof?

From the base of the focuser I have added about 75mm (35+40) spacers and I yet move the focuser back 15mm

Waterproof? why?

I have user the camera in minus 27 degrees celcius and had no problem.

I have recently bought the Omegon 16000 Mono. I did the sharpcap sensor analysis and wonder if someone knew to explain what i should do with the result.

"To combat cold hardware. I have it in a box with towels and warm water" ... leaks happen.

From that table you can conclude that unity gain is about 500 and that at that gain you lose a bit of dynamic range (11.2 vs 12.0).

 

If you want maximum dynamic range you should use gains from 100 to 251.

 

But to get better info, go to histogram in SharpCap and click the "brain" icon. If you have your camera pointing to the sky, it will measure the sky brightness level and give you the optimal gain for unity gain or the optimal gain for maximum dynamic range. You can also input a value for sky brightness level instead of measuring it.

 

You can find more info here:

Most of the sensitive hardware is above the warm water and it is packed in plastic bags too.

I ordered veTEC 533C and Optolong L-Extreme 1.25" filter yesterday! I have to wait untill april 1st for the new cameras become available. I hope that I wont have to wait even longer than that and the camera will be available after april 1st. My real problem is Bortle 9 sky in my backyard and finding time for astrophotography is a real mess due to bad weather on weekend every time in the new moon period. This filter allows the imaging on moonlight and in light polluted areas, so I can take images in the middle of week after work. DSLR imaging allowed me imaging only at clear moonless weekends which are rare here and that occures once in a half year or even 8 to 10 months! This will allow me to image the nebulae more often and the astrophotography setup wont lay around unused as it should be.

Now it seems that veTEC 533C is out of stock for unknown period. I paid for it and for Optolong L-Extreme 1.25"filter, but not recieved them yet. It seems that this pandemic and vessel stuck in the Suez canal will impact of many goods transport delay. I had too big expectations.

Do you finally decided your gain and offset values?

(Owners) :

 

Do you finally decided your gain and offset values?

I've been using these:

 

Gain: 0 for maximum dynamic range. 309 for unity gain. I arrived at these values doing multiple sensor tests in SharpCap.

 

Offset: This one is trickier. I use 128 regardless of gain setting. I selected it just because in Astroberry/Stellarmate you get 64, 128, etc when clicking the arrows in the offset field. When taking darks with an offset of 128 I got mean values of 126-127 ADU and minimum values around 40. When using 64 as offset I got minimum values of 0. I think that means that I was clipping the lowest values of the random noise. So I decided to stay at 128 offset. You can probably use any value around 100-120 and it will be OK.

 

I don't know if this is the right way of obtaining a good value for offset, but seems reasonable to me.
