Quick questions here. A friend and I were thinking of building a DIY telescope. Ofcourse, mirrors are a problem. We don't want to go through the trouble of making our own mirror. I'm guessing there's quite a few places that sell them. Are they affordable? Got any links for me?

Thanks.

I just finished building a 6" Newtonian on a Dobsonian mount. Got my mirrors from these guys http://www.e-scopes.cc/ and I've been quite happy with their service and the quality of the mirrors. For eyepieces, I just grabbed a cheapo 25mm Plössl from http://www.surplusshed.com to play with until I'm more comfortable selecting eyepieces (and have more money to burn).

Don't do like I did at first and buy a cheapo mirror off Ebay (focal ratio 5, my rear end; more like 3). A decent mirror will definitely cost you, but I've been amazed with the quality and amount of detail I've been able to see with my scope, even with a relatively low power eyepiece.

I don't know of any stores that sell them (I'm sure there are several tho) but you can find the mirrors and eyepieces on ebay for not much. I was planning on building a 8" dobsonian telescope and IIRC it was going to be ~$250-300 for all the the 2 mirrors and eyepiece assembly.

Really? That seems a bit much for the mirrors and such. A few bucks more and I can buy a commercial telescope of the same specs from what I'm looking at. How does that even happen?
