I bought the Samyang mirror lens to tide me over whilst I refurbished and upgraded my observatory and CPC110. Optically it's a bit 'soft' but clearly isn't well collimated (a common problem with these lenses apparently). There's no obvious way to fix this (though there is a plastic cover on the corrector plate that I'm tempted to lever off...). It has produced some images which should be useable for photometry - watch this space!
