You’ll find some ACF and non ACF Meade’s in there and the filters allow you to compare these.
In short there’s not much difference between ACF and non ACF. Meade’s quality as with Celestron is quite variable from scope to scope so you might be lucky, but most probably it will be fairly mediocre.
The Russian site from which the data is drawn is also linked - however if you are using a PC be careful as it attempts to install MALWARE on windows systems.
