Hi guys,
I'm looking at getting a flattener that won't affect the focal length of my scope (WO FLT98) and found one from telescope service that will fit directly on to the focuser and leave me plenty of room to throw an OAG and filter wheel in later down the track if I go that way.
But I'm struggling to find information/reviews regarding it's build and optical quality etc. (see link below)

The sample image on the site suggests it does a good job, but I'm hoping someone on here might have more information or maybe even have used one before.
Any suggestions or hints would be great.
Cheers,
Bret
