Mmmmm, the AT is an ED ( sorry, forgot to mention ) and my Achro shows CA as soon as I get any degree of magnification in the image was the thinking. Also F7 will get me in bit closer image wise.
I'm having difficulty with the 10" f5 photographically. It is big on the mount and supersensitive to collimation and coma. I've actually switched to the 114 f8 Newt at present due to the longer f and lighter weight.
I see all these excellent images from 80-100mm ED APO scopes and thought it might be a good option to try. F7 is still pretty widefeild. I'd probably sell the f5 Achro to offset.
Cheapest (new) APO over here is $1395 (80mm), the 100mm is $1995. This is at $650 start bid.
I may look at bringing an APO in from Bintel, it's at just over half the new price here. Even paying shipping it's a win.

Am I going down the worng track photographically to go small APO ?

I understand your comment re clutter Bojan. I've been minimising my setup and connections to the mount as well. As much as to make it easier to manage and not get lost in all the hardware as anything. Especially in the dark !!
