I bought this to try and flatten the field on my TS 80mm triplet F6 scope when using it with a Nikon DSLR. Without it, the scope was producing unusable images where the stars towards the corners were more like streaks than round stars. Once I included this field flattener however the results were transformed. Perfect round stars across the entire image. I also managed to connect my filter wheel between the flattener and the scope and was still able to achieve focus so I'm really pleased.
One point worth mentioning is that the nosepiece is quite long and was initially hitting the inside of the focuser before reaching the flange so you might want to look at a lower profile version. Since I took this off to attach the filter wheel, which has a low profile nosepiece anyway I now have a solid unit.
I would recommend this flattener to anyone using a DSLR and a fast refractor. Totally worth the money.
Thanks again FLO

I bought this for use with an Equinox 66. I had to purchase a low profile SCT to T thread but the bonus is that with the flattener and a 2" LP filter its all focussed without adjustment (fully racked in). As for the performance of the flattener, it works perfectly. Some comparison pics can be found here http://stargazerslounge.com/topic/200692-equinox-66-advice/

Bought to go with Equinox 80 and QHY9M with QHY USB wheel. Great round stars right to edge of field with no change to focal length. Used at 52mm from sensor. Clear skies

Bought this to go with the Skywatcher Equinox 80 APO PRO OTA f/6.25 and a canon 7D. Flattener screws directly into the T to EOS adaptor. Corner stars are now very good and round.

I bought this flattener to use on a Revelation 600mm f/6 scope, as the scope was being used with a DSLR I didn't want to reduce the focal length and f/6 was fast enough.
The stars on the extremes are very well controlled.
The quality is superb, beautifully anodized a glossy black, the elements are Gin clear with nice looking coatings.. Excellent value..
Easy to use and great value.

I bought this flattener to try with my William Optics Megrez 72. I had previously been using a combined flattener and reducer which proved difficult because its performance was incredibly sensitive to having perfect focus.
This flattener is much easier to use. The stars in the corners are much better shapes and much easier to achieve. It's not a focal reducer, so my scope is still at f/6 which means I have to expose a little longer, but that's no problem.
Best of all, this performance comes at a great price. You can spend a lot more flatteners and reducers with no performance guarantees with your scope and camera. I use this Skywatcher flattener all the time now.
