Ok the final word on the Televue RFL-4087 .8X reducer flattener on the 127ED.
It fails.
I aligned my ML focuser to the OTA using a LASER (thanks very for the loan from a fellow IIS member Visionoz) and the results, while improved are probably only acceptable in star elongation to around 70% out from the centre.
This image is a corner crop but it gives you an idea of the best I can wring from the reducer flattener. F6 imaging looks great with this scope (with the reducer fitted) you get a whole lot more sky real estate but the damn star elongation is a real off put. I'll still use it but crop out the offensive areas...which kinda negates the reason for a reducer.
Thus I do not recommend the Televue RFL-4087 .8X reducer for this scope. Looks like we have to wait for the OEM to get their act together. Sigh....(That was an expensive mistake) ...if ever at this rate.

Brendan
