Upgrading focuser on Lunt LS50THa B400 from helical to better ?

[Altair8389]

Hi all,

I am thinking of adding to my solar equipment by getting a second hand Lunt LS50THa with B400, for about 700 pounds in UK.

Is this a fair price. It is about 4 to 5 years old.

I wonder if it is reasonable easy to upgrade the focuser to a rack and pinion so I can maybe add a motorised focusing system to it.

Any one who has done this modification or knows about it, please advise.

 

Many thanks.

Look out for one with the FeatherTouch option. Expensive focuser to buy seperately but have seen LS50s go for about 850 with the FeatherTouch.

Either the FT or Moonlite is a huge improvement on the awful helical. The helical on my old LS50 locked tight and the scope had to be sent off to Germany to be sorted.

I  changed the helical focuser for the feather touch. Expensive but what a difference it made.
