So.....some weeks ago Steve (masraun) generously gifted me a 2x Barlow lens (he didn't even let me pay postage), and I think I should report back:
First, a public shout-out to Steve and a thank you.
This time of year, the sky is almost always cloudy/foggy but I have had a couple of chances to get outside. First, it appears the planets are all hiding around the Sun right now. This will change of course.
AFAIK, planets are virtually the only things of interest when using a cheap, wimpy telescope like my 102mm refractor. Otherwise, there are twinkling stars I suppose. Looking forward to getting to the other side of the Sun.
One thing I did notice is that, particularly with the additional 2x magnification, stuff moves out of view somewhat quickly. I imagine you guys have devices that allow your scopes to track objects and hold them in view.
