Have you purchased the telescope yet?

No, i want to decide for a good telescope with a good price.

I don't know much about telescope purchasing, I am still trying to get the hang of it. But, a lot of people suggested to me getting something from Orion at

They seem to have the best prices for beginner scopes. And if you're not set on an eq mount, their Dobsonians are on sale right now.

Also, you might want to PM a moderator and ask them to change the title of this thread to something less vague. There are are a lot of extremely knowledgeable people on this forum when it comes to scopes. But, they might not even bother to look at the thread because of the title. I almost didn't:wink:

Good luck! And if you are new to astronomy like I am, don't overlook a sweet set of Binoculars. I got" for Christmas from my girlfriend and they are AMAZING.

I saw M11, my first galaxy with them last night! They have great optics and are very portable. I built a parallelogram mount for about $40 out of hardwood.

I second that. Your brain is made to use two eyes and you will probably be much more comfortable with binos at first. I use mine more often than I ever did my scope; partly due to the comfort and partly due to being able to take them anywhere.

Ignition, do you know what you'd like to use your telescope for? If you want to do astrophotography you'll need a eq. mount for star tracking, but if you just want to look at things, I'll second Saladsamurai's suggestion about the alt-az dobsonians. You can probably get a bigger dobsonian for less if you ditch the equatorial mount for alt-az (but you also loose the star tracker!).

And thinking about it now, the eq. mounted dobsonian you linked to might not be that good for astrophotography. You'd have to consider the difficulty of mounting the camera way out at the end of the tube where the focus is. Anyone have any experience with that?

It could be a very good general purpose scope - depending on price. I would set the cutoff at around $450. If it's pricier than that, I would look long and hard at a cat scope. I like the short f. It gives gives a fabulous wide field view and good portability. I don't like dobsonian mounts, but, it sounds like it's available in a tricked out configuration that is functionally equivalent to an equatorial mount. Portability is a huge consideration for most people shopping for a scope - an issue not fully appreciated until saddled with a poor choice.
