Alpha Lyra Reviews

On Our Theia 90 Star Diagonal
“First impressions of the diagonal itself are very favourable, looking like a solid and well-engineered piece of equipment.“ “Using Jupiter and a third quarter Moon, I evaluated scatter around the object which can diminish the visibility of low contrast surface features. If there were any differences in brightness and extent of the scatter (measured against the position of the Galilean satellites), I was unable to see it.“ “All these tests lead me to conclude that mirror in the Theia90 is of high quality and very much the equal of other quality, highly reflective mirror diagonals”

On Our Cerberus Case"The team seem rather proud of these cases and just how robust they are as Nick (who stands over 6 feet tall) demonstrated to me at Astrofest by standing on the case and then jumping up and down on it. [...] the Cerberus Case would be an excellent choice for an eyepiece case or as a travel case for a small 6-8cm aperture scope and accessories for trips to dark distant lands as those dimensions comply with the most restrictive of hand baggage allowances."
