ne3V1r0y i had that issue the first night with 30 sec captures in EQ - only one 30s capture in 5 minutes.
Changing to 20 secs is a quick fix.
Longer term fixes I've found:
If you are using the stock short tripod, put it on the solid ground and not on a table, chair or car where there is some microscopic flexing to affect EQ performance.
I have a bigger tripod and I put 5 pounds ballast hanging from its ballast hook to secure it solidly to the ground.
Do the polar deviation routine twice. I had it in the greens 0.5 or less on both but a second immediate routine had those two numbers in the red so I dialed it in again.
While the software gives you a checkmark at 1.0 or less on both, I don't consider it good unless both numbers are 0.3 or less.
I am now able to do 30 sec captures with 50% or better acceptance after the ballast and multiple polar deviation routines to start. After an hour of imaging, I redo the polar deviation routine, trim it to 0.3 or less, then my 30s captures improve to 80% acceptance rate.
