Lhires III Be Stars and Telluric Alignment
The following is a small sample of Be stars acquired as part of the BeSS initiative showing excellent alignment with atmospheric telluric lines, despite using only a 3 line, second order polynomial dispersion calculation for spectral calibration.

FSQ-85 & the Alpy 600
A test of the Shelyak Alpy 600 using a Takahashi FSQ-85 shows extremely well corrected spectra, particularly notable at shorter wavelengths which are typically problematic for refractors of simpler design. A link to the report: FSQ-85 and the Alpy 600 … Continue reading
