On this page, I present some information about my ZWO ASI462MC color camera (bought on December 20, 2022 in the astronomie.de forum, arrived at my home on December 24, 2022). This camera has the same Sony sensor as my Vaonis Vespera (Sony IMX462), so I was interested in finding out how it would perform on my telescopes in comparison with the Vespera (and my other cameras).
See the appendix for the technical data. See also:
Note: The camera was discontinued and replaced with the ZWO ASI662MC.
In 2022, I had "consolidated" my camera equipment a bit by selling my ZWO ASI224MC and buying a ZWO ASO294MC. Also, at the end of the year, I had offered my Atik Infinity for sale in the forum of astronomie.de (and sold it...). Then, just before Christmas, I came across a mint ZWO ASI462MC in the same forum (Biete = Offers) and purchased it, because it has the same Sony sensor (IMX462) as the Vespera. So I would be able to conduct a similar comparison between the two devices as between the ZWO ASI224MC and the Unistellar eVscope.
However, I found a note from ZWO (and not dealers) that the camera is no longer manufactured and has been replaced with the ZWO ASI662MC...
I am also curious whether the camera will work on the StellarMate astrocomputer or if it will cause similar problems as the ASI224MC.

Here, the ZWO ASI462 is shown at the Omegon PS 72/432; the photos are processed by the StellarMate astronomy computer, which is controlled using an iPad. The photos show a complete EAA equipment!
The ASI462MC camera uses the Sony sensor type IMX462 (CMOS) with a resolution of 2.1 MegaPixels, or 1920 x 1080 pixels (H/V). The pixel size is 2.9 µm (quadratic pixels). With this, all sizes are known to calculate the field of view of the camera at different telescope tubes!
For simplity reasons, I did not calculate the values myself, but used the Website astronomy.tools for calculating the field of view of the ASI462MC camera at my current telescope tubes (as of December 2022):
Legend: Cyan Custom Scope = PS 72/432, magenta Custom Scope = TLAPO1027
I summarize the results of the diagrams (and others shown elsewhere) in the following table:
