Apex-ED reducer

[Anthonyexmouth]

Anyone here got any experience with one of these? Are they a worthwhile upgrade over a stock manufacturer reducer?

The x0.65 is quite aggressive, you might find you'll never get a flat field with it at the edges as I still struggle with the 183 sensor size but I normally crop, and with singular targets if you crop you won't even see the edges. The actual unit is nice and weighty. I still use it quite often though due to the speed at f3.8 and the 234mm FL it gives me with the z61. The normal flattener gives me f5.9 and 370mm FL, so it's quite versatile in offering you framing options.

I used it for this, you'll see the odd shaped stars in it:

Probably not worth it then with a 4/3 or cropped sensor. If i'd have to crop too much you lose the benefit. I thought the flattening might be better than the stock.

The riccardi is not as harsh and a better balanced reducer.

Think I've got my backfocus as good as I can get and tilt is pretty good too but still a little distortion in subs but seems to clean up ok after stacking. Wondering If a better flattener is an option or maybe just throwing money at a problem that isn't really there.
