Dear Clive
I own a LISA but cant comment on the dados as I havent seen one.
I decided to purchase the LISA as I found that my scope was not big enough to give bright enough spectra with a higher resolution spectrograph.
The purchase process was very easy. I had it freighted directly from Shelyak. I had to pay GST but the customs system worked well.
With the neon calibration unit it is very easy to achieve accurate calibration and the processing pipeline using Isis is simple.
It is a well built device and coupled with a good guider is easy to use.
Using a C11 scope I can obtain reasonable spectra down to mag 14 for SN etc
Cheers
Terry
