Since this is the reflector forum,the cheap Newtonians only fitted with a 1.25" focuser on Newtonians, and low grade ones at that, should be avoided. Those are usually 6" or smaller aperture, whose buyers are not taken seriously, 8" are only just... It's fine and sometimes fun if a...
Thanks for your very clear post, Don. I found a FT2015BCR focuser in the second hand market. This will replace the FT2020 of my dob - I will probably install the FT2020 on my 4" refractor. Doing so, both focuser drawtube and PC2 back will be flush with the UTA internal wall. Reg...
