Re: Double stacking a Lunt LS80Tha with a SolarMax II SME-90

The problems with the Richview etalons is that their CWL can be rather high, and when tilt-tuned they suffer from significant banding. When Richview compression tuned, excessive central spacer pressure distorts the etalon gap and the FWHM becomes rather large. A combination of tilt and compression ...

Double stacking a Lunt LS80Tha with a SolarMax II SME-90

Hi all I'm wondering if it is possible to "double-stacking" a Lunt Telescope with adding a SolarMax double stack module. I have a Lunt LS80Tha and I'd like to buy a SolarMax II SME-90 double stack module. What do you think about the possibility of a good success of this project? Thank you ...

Tks
