Features & Specification
The 0.77 Reducer is absolutely excellent, working brilliantly with the Esprit 120 (focal length 840mm at f7) and giving me a whole lot of new options, presenting me with a telescope of focal length 650mm at f5.3.It produces exquisite details and perfect starsI now have an additional telescope thatís fits in between my Esprit 120 and W.O. Zenithstar 81 (440mm with its reducer). I did require some help from FLO in fitting the reducer. I did not realise that it has to inserted deep into the focusing tube of the telescope to engage with the screw thread!
No. Guiding software is only interested in the centre of the star and is usually very tolerant of star shape so a flattener is not necessary.
