Newtonian adjustment is more comfortable/easier if you replace the secondary mirror adjustment screws with knurled screws

Newtonian alignment is more convenient/easier if you replace the secondary mirror's adjustment screws with knurled screws.

These are usually M4 screws with a length of 35 mm. To do this, you remove one screw at a time, which avoids having to disassemble the secondary mirror holder, and the adjustment remains roughly intact.
