Thanks Jase. yes, the ED80 is very good value for money. It was just a bit more than a normal Achro, but
very decent colour correction.

I've learnt the importance of decent amount of data and have changed my approach from trying to
nab multiple targets in one night, to atleast a few hours on one target to do it any justice.
Startools did an excellent job at controlling noise.

Thanks Geoff. I didn't have to sharpen this, just focus. need to get a Baht mask made.
the Tilt is probably my dodgy 2 inch Extension tube that has only one nut holding the whole train.
I do push the OAG flat against the drawtube and then tighten, but I've got to get some threaded adaptors to remove tilt.
This is still the stock focuser though so may have some small tilt.

Cheers
Alistair
