EdgeHD secondary mirror advice

[JonHigh]

Hi all. 

A bit of advice please… After mucking about with the collimation screws on my SCT, I have been wondering if there is something like a home/reset position for the secondary mirror screws. Start from scratch as it were. Or best not to worry about it?

No, the reset point would be perfect collimation. I would just perform a star test to set the collimation at high magnification on a perfectly centred star.

like bosun21 says, no there isn't. if you're struggling (like I have in the past) you might find this useful, it sorted me out.......
