Hi Rod
Glad to hear that the damage was not significant. Among my collection of telescopes, I have an 127 X 1200 achromat, not E.S. or Bresser but is similar enough. These scopes perform well enough, not apo quality but I use it or have used it in the past for public nights when you don't want to use the more expensive gear.
One item that will improve the CA in your achro is an Minus Violet Filter, there are several brands available with the pick of the bunch probably being the Baader Semi-Apo Filter. Not cheap but works very well at taming CA, some colour fringing will still be visible at high mag on bright objects but is not as annoying as some people would like to allude to. Also, some eyepieces also introduce their own chromatic aberrations so it can get a little confusing at times. Good quality Plossels are good performing eyepieces, without breaking the budget though the 50 deg AF is a bit narrow for some tastes these days.
Wider field eyepieces, unless premium brands may have some chromatic errors of their own or be a bit soft at the edges of the field of view but you may already know this. The 2" diagonal teamed with a good 2" widefield eyepiece is great for nebulae and star clusters on dark of the moon nights too.
Enjoy the ride.
