I have had a FLI PDF and currently use a FLI Atlas. I have not used the Optec. Is this the Optec model that includes a rotator?
The FLI PDF was a very nice and reliable focuser. With imaging you want the strongest focuser possible as flex can ruin your images.
I used the PDF with a FLI Microline and also an Apogee U16M and Proline 16803. It handled them both well.
Are they the same price?
Greg.
