Starguider flip mirror

Good morning everyone, just wondering if anybody has used a Starguider flip mirror? Thanks in advance for any answers.

No, but I have a flip mirror I bought used IIRC, which has no evident branding other than 'TS'.  It worked well, and has various bits which unscrew to make attachments more versatile, and the eyepiece focus can be adjusted.

However I have switched away from using it, partly because the combination of this and a focal reducer and camera was too long for my SCT mount and made it impossible to image anything at medium or high altitude.  The equally effective alternative is to use Precise GoTo and if necessary a right-angle finder to get the supplementary guide star centered.

I also had a worrying accident when I unscrewed the camera from the flip mirror in the dark and found I had unscrewed part of the camera and nearly lost the optical window.
