ZWO asi071MC sensor size

dbock1

I have a question on the chip size of the ZWO asi071MC camera.

I have searched for this for awhile, and found it to be 23.6mm x 15.7mm overall.

Is this correct?

I'm trying to use my images to determine exact focal length of the image train, for fine tuning my RC, using plate solving software, which gives me the dimensions of the image in arcmin for both axes.

If the dimensions are correct, I can compute the focal length of the telescope.

Currently, with these dimensions, I've computed it to be 2021mm.

The stated vendor f.l. should be 2032, for optimum performance.

I just want to make sure the chip acquisition dimensions are correct, before moving the primary.

Thanks.

Using the diagonal size of 28.4 mm for the sensor, which is published on most sites for this sensor, I've computed the focal length to be 2023, based on the Astronomy.net data from several images I've taken.

Yes, you are correct. 23.6mm*15.7mm
