An other issue / problem with may 294 MC Pro and calibrating frames

Astrop

If you set your cooled imaging camera to say minus 10 Deg C, that's it. All your darks, dark flats, flats are imaged at that same minus 10 Deg C temperature as you had been doing with your lights which your software should tell you what temperature the camera sensor is at in real time. Most people with cooled cameras create a library of darks, even dark flats and can reuse them years after (I haven't redone my 183 darks for three years), did you not do this?

Astrop That´s what I thought all the time. But I do as you can read above my darks in the fridge because I needed totally darkness. This darks aren' working. Then I take again new darks outdoor in a clear night and this darks was clean an work properly.

Sure I do a library.

Tobi294MCPro I'm glad to hear the problem has been resolved. However, it's a bit unusual that the ambient temperatures for both the dark and light conditions need to be identical.

The amp-glow is typically caused by heat or near-infrared (NIR) light from the supporting circuits. When you set the target cooling temperature to -10 degrees, which means the sensor will cool to that temperature as well, allowing the amp-glow to be properly calibrated.

Could you let me know how you were capturing the darks previously? Also, what was the difference in ambient temperature between the dark and light conditions?
If you would share some new darks with us we appreciate that. thanks in advance.

Tech@ZWO yes I'am suprised too. But it is so like i wrote here.

Previously I do the darks in the fridge because of totally darkness. I didn't take them outside all the time.
The lights were taken at maybe 13-15° , the darks were taken at maybe 28-30° in my bathroom and they didnt work, the other darks before from the fridge there was the fridge at 4° and this also didnt work.
Then the new darks I shoot outdoor at maybe 15-16° and this was fully success and work properly.

Yes, I will upload my newest darks. Do you have the older ones still at your computer?

Tech@ZWO

Tobi294MCPro Yes i kept them, thank you very much that you would share the new darks with me, i will look into this issues once i get them. thanks again.

Tobi294MCPro Got it, thanks.
Clear Skies.

Tobi294MCPro

Tech@ZWO Okay. Let me know if you have looked into.

Thanks, dito

Tech@ZWO

Tobi294MCPro Sure, have a good day

Any news?

I actually have again the issue with the black dot and the same darks as at the heart nebula. It looks like sometimes they work, sometimes not?
