New Camera Information / Unlocked mod QHY294C pro
« on: May 16, 2021, 10:50:03 AM »
Hello, do you know if the unlocked mode of the QHY294C pro is usable? I understand that no processing software supports this mode on the color model, do you have any recent information on the subject?

Thanks, Nicolas

Image Issue Q&A / Flat and doubled stars
« on: April 02, 2021, 02:31:15 AM »
Since a few days I have a problem with my cooled camera (QHY290MM), I get "flat" stars as soon as the cooling is active

I specify that it has nothing to do with a tracking problem, the stars become round again if the power supply of the camera is cut, and they are also round when the cooling is pushed to the maximum.

Without knowing why, everything goes back to normal after 2 or 3 hours.

Does anyone have any idea what could be causing this problem? I specify that no matter the power of cooling of the peltier, the fan is always active and turns at constant speed as soon as the camera is connected to its power supply.

New Camera Information / IMX485

Hello, the imx 485 has been available for some time now and I am surprised not to see any test or image made with this camera, even less in deep sky.

Do you intend to release a cooled version of this sensor, or better yet a monochrome version?

I practice EAA with 150/750 and a cooled QHY290MM, and it's really amazing what you can get in less than 20mn on galaxies! Unfortunately the field of view is very limited and we have to be content with aiming at small objects.

an example obtained with my setup: 40x30s 150/750-QHY290MM cooled

Between the small sensors type 290 and the medium sensors like the 183 and the 294, there is nothing recent and as efficient. A sensor like the imx 485 would be perfect for this use, the same resolution as a 290 with a much larger field, and obviously just as efficient, but it lacks the cooling which is still important when making 30s exposures.
