I've recently bought a very reasonably priced Aquila 90mm 500mm Refractor.
These are made by the "Yuzhong Optical Instrument Company" and available from Chinese sellers on eBay.
It comes with a"Vixen" style Dovetail so it went straight on to my EQ5 Mount
I've fitted it with a Bintel (GSO) 2 inch mirror diagonal and 1.25 inch adapter. It came with a T mount tube so after purchasing a T ring for my camera I was set to go. I also bought a Bintel 50 x 8 Right Angle Finder, I like it.

My first pictures showed quite a lot of purple fringing, which I could reduce in post processing but I wasn't really happy.

This is the first output from the scope and filter. I'm very happy now, both Light Pollution and "Purple Fringing" suppressed.
