"Lift front End of Telescope up on mounting plate"

[prefetch]

"Lift front End of Telescope up on mounting plate" is the note next to Collimation in the correction report on autoslew.

 

this doesn't make a lot of sense to me.  does anyone else get this?

This means that the central axis of the telescope is not parallel to the mounting plate. You could put a thin metal shim between the plate and the tube rings near the front end of the telescope.

However, the software allows or this so you don't need to do anything.

thanks george.

 

i'm just trying to fine tune everything now that i have my C14HD using scope rings and the big ASA mount plate.  the sequence flexure test tells me that i'm down to about 5" from 36" on my previous setup, so i'm getting much better - just trying to see where else i can optimize.

Hi Prefetch,

 

 

Happy to see that your setup has highly improved. Good job.

 

Collimation gap is a predictable error that the software is able to compensate precisely. So you don't have to worry about it if it has reasonable value like the one you got.

For flexure, it is impossible to predict the impact in any position of the scope so it should be minimized as it cannot be compensated.
