heq5 synscan upgrade

[Pete Presland]

now i seem to have everything pretty much as i want it in the obsy.i know saving for a heq5 synscan upgrade kit.

First Light Optics - SynScan PRO GOTO Version 3 Upgrade Kit for HEQ5

when fitted does this allow for a less critical polar alignment?

Accurate polar alignment is still needed to allow the mount to track. Goto won't compensation for bad polar alignment.

it just made me wonder,why when i did a two star alignment on my etx125 there was no polar alignment involved,but the tracking seemed quite good.

obviously not good enough for long exposure imaging and there would be a rotation issue.

The ETX125 has an AZ mount which doesn't require polar alignment. A goto EQ mount still needs a decent polar alignment to accurately track and to allow the handset to map the sky after star alignment.

thanks and there was me thinking i could avoid the perils of polar alignment

[Cornelius Varley]

There is no escape but it is not that difficult.

i have had it reasonably close,but this winter i want to try some serious deep sky stuff,so its going to have to be much better.

the only help goto with give you is when you get to guiding which i dont think your mount can do, guiding does compensate for bad alignment but as your lucky enough to have a perm setup its worth putting in a few hours to get it spot on i think
