Hi All,
I've been thinking for a while about replacing my the spider on my 10" Quattro and i don't want a direct "like for like" replacement in terms of the mechanical design, as i think the secondary design is really bad in terms of accuracy and fine adjustment.
So i did what everyone would do and set about googling, and i came across what looks like a unique design on Ali Express.
I particularly like the way the secondary is threaded all the way through to the mirror holder to give a much more rigid design and the way it's had holes tapped in increments so you get a good idea for rotation position. Then looking further at the rotation, it has fine tuning like that of Azimuth mount with the central peg, which looked interesting.
My only concern is having to remove the secondary mirror and then glue it to the new secondary holder.
I just wondered if anyone else has used on of these spiders ?
Many Thanks,
Rich.
