Re: RA and DEC cables?
No they are not. There are knock offs available, but still quite pricey.
I noticed my QHY guidecam has this connection, I assume as a USB alternatively. I beginning to love QHY more and more!
PS George Cusing would you upgrade the MaxESP32 to use these in place of RJ45? They do board mount. Now we just need to find multicore shielded cable that stays flexible in the cold weather months.
