Re: SW Virtuoso 150 mm F/5
Pedro, I'll move this to the commercial solar section where it may get more interest

Re: SW Virtuoso 150 mm F/5
Hi Pedro, I have some experience with the original 130mm and can add a few things, which are relevant also to this new version.
1. The telescope has a Vixen dovetail so it can be put on many other mounts (e.g. GEM) if desired. This increases the flexibility.
2. The mount can also be used with another telescope, as long is it is quite short. I have put a 150mm Mak on the Dob mount that came with mine. You could probably put something like a 60mm Lunt H-alpha on it.
3. If you want to reduce the central obstruction, it is fairly easy to change the secondary mirror (it is held on with some kind of double sided tape). I calculated that the included secondary mirror was quite a bit oversized. For things like planets, with a narrow field of view, the telescope would benefit from a smaller obstruction that a smaller secondary would bring. I actually reattached the secondary in a way that I could easily swap mirrors.
4. I have done some imaging with my version and I found it useful that you can shorten the tube very easily to increase the back focus. That way, you can add some filters and a short helical focuser (so the camera does not rotate).
5. You can wrap some Teflon tape (like for plumbing) around the included focuser to make the movement a bit firmer and smoother.
6. The mirror is a lot better than the included eyepieces.
7. The telescope is a very good basis for a solar Newtonian.
