This is probably one for Jasem as it involves Optical Trains and possibly the mathematics surrounding them...

I was trying to set up an optical train including my TeleVue x4 PowerMate last night and discovered that the Reducer/Barlow spinbox has a maximum limit of 3.00. I get that there needs to be a limit but is there any reason this couldn't be increased? Maybe to a maximum of 5.00 as the x5 PowerMate is the highest magnification that I'm aware of as being readily available.

Sure, I'll change it to 5
