Thanks for the link Justin, I'll have a look a little later when this headache clears off.
The repo is probably a bit too saturated for me at present. But I'll take a look a bit later when, you guessed it, this headache clears off. Rotten headaches.
I find saturation a tricky one because my brain definitely does compensate and I can get used to both over and under saturated images if I stare at them for too long.
The collimating tool arrived in the mail and now the scope is nicely done. Was easy to do too. Going to love this scope me thinks.
