I used one of these both visually and for imaging with my 12" LX200GPS
Visually it was excellent and the F ratio variability made it versitile.
Here are a couple of images using it and the 12" LX200GPS at approx F6.7
NGC 1365
Dumbell Nebula
Lagoon Nebula
The diffraction spikes were added via crossed sticks over the objective - hey, I liked the look
These were all taken on the native fork mount too
This the GEG on the Meade 12" in visual mode
Hope this helps somebody make a decision
