Out of interest, what telescope did you use the SHG on, and was anything used to reduce intensity upstream of the SHG (eg a white light herschel prism)?

First light was on my AP130GTX...at FL 819mm just a bit too long for
the SHG slit aperture to capture a full disk. A FL of 600mm should be perfect.
The reason I went for the MLastro was the CNC milled
metal housing,
micrometer focusers and you can use it with up to a 150mm aperture without the need for an ERF.
That said, I suspect an objective-end ERF would be a good idea...heat is never good for images
