  1. Hello Stoffe. M v h Gunnar
  2. Hello and welcome to SGL!

  4. Hi There are no springs between backhousing and mirrorcell on the MN190. Primary adjustment screws run thru flexible rubbergrommets as i remember it, not much flex in them they are only about 6mm thick. http://stargazerslounge.com/topic/141012-skywatcher-190mn-fitting-of-a-moonlite-focuser/ Gunnar
  5. I follow this with interest Per!
  6. Minor batch in progress.
  7. Hi Robert Yes as Per says, the secondary Is glued with adhesive tape from the factory. I have replaced the double-sided adhesive tape on my 190MN! My secondary-mirror Is now glued in position with 3 blobs of silicone glue, not tested yet so cannot tell if there is an improvement there. Regards Gunnar.
  8. Yes, that Is correct Stuart! It Is a fullframe.
