Decided to upgrade my AP Honders focuser with a FLI Altas due, on going random small focal plane tilt variations with the standard 3.5" AP unit.
The FLI unit has a nice innovation by way of their connectors that pull everything orthogonal when torqued down. My only gripe would be the rather short 1/2" travel limit of the focuser...plus the need to get some not inexpensive custom connectors made for the Honders, (thanks to AP for supplying the specs to precise parts )
The system now produces sublime star images right up to the edge of a KAF16803 sensor...no mean feat...Anyway, as they say one picture can say a thousand words.
