This may open a large can of worms, but I see some suggestions that upgrading my 8SE to a 2" diagonal might provide better viewing. And others which say that actually their 1.25" diagonal is just fine, thanks. And some say "get a better diagonal than the Celestron stock model, while some say "the stock Celestron is fine". This conflicting information is as natural as a preference for chocolate or butterscotch topping - personal taste is what it is, and we all have our own. But there has to be SOME objective reality when something is clearly better, or clearly more clear. So...
1> Can someone please explain the reason why 2" is better than 1.25"? Is it wider field of view? More light gathering/transmission? Better manufacturers or precision at the top end? Is it substantially more money, for very little difference? I really have no idea why one is superior over the other, if indeed there is an empirical, objective difference, rather than just personal preference. ??
2> I see some EPs that are both 2" and 1.25", and adapters to allow each size in the other size of diagonal. Is an EP that fits both just a 1.25" EP that has a built-in 2" adapter? Or is it different than that simplistic supposition?
3> I would assume that once you go one way or the other, that you've picked your foundation and now everything you buy or use matches up to that diagonal decision. So, if you buy a 2" star diagonal, you just trade in all your 1.25" EPs for 2" EPs, and that's that, now you're a 2-incher. Or vice-versa. But it sounds like some - perhaps many - people in CN actually have both sizes, and use both. ?? Wouldn't you just pick one size and go with that size for everything, from then on? Or does the answer take its cue from the answers to question #1, about there being times when 2" is preferred, and times when 1.25" is preferred, so that eventually you end up with some of each?
Thanks in advance for your answers and advice.Also, if this belongs in the "General Viewing" area instead of the newbie area, please let me know and I'll see about getting it moved to where it should best go
