Quote: Thomas what about the C8 and 12" reflector.

Quote:Sorry to hear about your lousy C8. Mine had fantastic optics, but that was moot, as the tube currents never settled in the carbon fiber tube (carbon fiber has TERRIBLE thermal properties for closed tube telescopes). I was actually thinking about letting Carl Zambuto work his magic on the 12" mirror, but he has stopped refiguring of cheap mirrors and I couldn't afford it anyway. Replacing the mirror with another GSO one seems to be the way to go. Teleskop Service in Germany sells certified mirrors with the same focal length and diameter as the one in this scope, but they are a little pricey. I'll need to save up for one, as I can't afford one right now. And then I find myself still dreaming about a large refractor... A 7" - 8" f/12 would be soooo nice! I am very tempted to get an ISTAR lens and build a large Richard Berry mount for it, now that I have experience with dobsonians and has seen how smooth and stable they can be. There is no question that a refractor would be far superior, aperture for aperture, in my climate. Clear skies!Thomas, Denmark

It is often said that to observe the moon, almost any telescope goes well.
But, in his opinion there is some model above the rest to be a little better for lunar observation?
From what aperture lunar observation becomes interesting, detailed and serious observation?
Quote:I realy considered mirror grinding some months ago. The hundreds of hours involved for the size I wanted and the improbability of success was a total downer. If I were younger with more hours in my day than I have now I'd be compelled. Such as it is tho - I have no such time budget or patience to make a 400 hour flop.

Telescopes are instruments of hope and faith. Hope that a better, clearer and brighter universe can be observed. Faith that we can bring these discoveries back to our small planet and create positive changes for all of it's inhabitants.
