I am curious to know if any other Skywatcher 10-inch collapsible tube dobsonian telescope owners have had the primary mirror tested by a reliable optician and the results of the test.
I have noticed that on the Moon and Jupiter both the contrast and resolving power is actually quite good, especially considering that the optics are mass produced. Now I am not claiming "apo" kind of views but definitely better than most SCT that I have observed with.
Considering my age and the fact that it is quite portable and easy for me to move around, I would like to, at least, hang onto it for a while. So, I really would like to know how good the primary is and if I get the polishing "tweaked" and probably change the diagonal for an Antares 1/30th wave secondary. After all, if I decide to keep this scope for "life", I want something with enhanced coatings and kick-**** optics. Going this way would definitely be less expensive than buying a new telescope.
So, has anyone who owns this scope invested in upgrading the optics and noticed a major improvement? I would like to hear your thoughts and opinions about this.
