I apologize if I did not notice this may have been already mentioned. 
It has been as well as methods to get around that problem ;)

For those interested in some beginning tips, this article may be useful, even though it deals a lot with meteors. It does have some settings:

Sorry, but I am unable to find where in the thread methods to prevent land blur with sky tracking is mentioned.
Help?

Joe,
Thanks for these references.

I have seen Adam Woodworth's presentations and he does great work.
He answered the question as I thought it would be done; requiring separate
exposures of land and sky for a composite. It would  have been nice to see a
comparison shot between the sky tracker method and star stacker method.

Seems ironic coming from the company whose image processing algorithms wipe out low magnitude stars... Not a problem for art photography but absolutely a problem for documentary photography.

I wonder how folks who look at the photos would be able to tell if they were accurate or not. All most of us see is a photograph with a lot of white or other color spots in a mostly dark background. How many of those "spots" there should be, where they should be or if any of them are missing/misplaced, etc., etc., how can I tell?  What about the photographers...can they? :)

Does it wipe out low magnitude stars in both JPEG and RAW, even the non compressed RAW ?

Dick,

It wipes out stars in both Raw and therefore I presume JPEG too. 

Here’s an article on the  Sony Star Eater Bug

Cheers

I don’t know if these images were taken before the firmware update or not, but there are more than enough stars in them for many photographers:

https://alphauniverse.com/stories/camer ... otography/

I wonder how many people want more than that! It seems it would just wash out the contrast in the skies and make it look like the Milky Way.
BTW, the firmware update came out in August 2016. A7rlll used in article came out in October/November 2017, so presumably would have the new firmware.
The photo referenced by Joerg here is another nice example of picking up plenty of stars.

One thing I don’t understand is the “never use auto white balance” statement if it only affects JPEG images. It should not matter on RAW images.
