Added some black stickers inside the new SHG tube and stray light blocker on the lens, I can capture the image of the sun today.
The result seems acceptable, although the scanning speed is still very natural and low (0x).

Turned the eq mount by hand and tried to speed up the scan and got an alien shape sun.

Also very important: need to make sure you are not recording sun while speed is in ramp up phase (accelerating)
but i was successful later on

2X speed 30 frames
