I'm going to the next star gazing family night at the Challenger Space Center Arizona, Peoria and see if I can get more questions answered. Please continue to give me any information you think can help me. Thanks

In Phoenix I have seen an LDX75 with 5" refractor go for $400. Good scopes do pop up quite often here.

There's a meade 8" LX10 in flagstaff for $650 with an electric drive. It'd be tough to get it aligned well for pictures, but it does have the wedge with it for $650

Or almost the same in a Celestron for $650 in flagstaff:

There's also an LX10 in Phoenix for $475 but it's missing parts.

So nothing really great atm.

You could do some decent photos just by mounting your camera on a decent tripod/mount. A used CG4 or so. Plus there are often decent refractors on CL that you could later mount on it as well. There was a nice Celestron ED80 for $250 just a couple of weeks ago.

If you're patient and you look, you'll probably find something good around here.

Thanks for the input. What do you think about the Meade ETX90. I found out that I can add a StarGPS to it for 129.00. Any idea how I can use my canon sx20 is camera on the etx90. I'm think maybe I should go with a web cam but my camera takes really good photos of the moon. It zooms to 80mm and you see the craters. Not really sure yet if I will go with the etx90 because I really would like to see good examples of what you can see through it.

This is a great idea. If you have the opportunity to view through some different kinds of scopes before buying your own you should take advantage of it.

What do you think about the Meade ETX90.


My first telescope was an Orion 90mm mak not too different from the ETX90 but without the electronic mount. The scope gives nice sharp views of the moon, is pretty good on bright planets, and can see/detect the brighter Messiers from my light polluted skies. The best part about the scope is the size; it's tiny so it's easy to store and bring along. A larger scope will show more detail on all targets. A 4" refractor is a significant step up. A 5" or 6" reflector or SCT would be too.

Note all the above is for visual use. I don't really image other than the occasional snap shot. Imaging with the ETX90 would be practically limited to moon and planets due to the long focal length. Here's a snap of the moon with my 90mm mak:

There is a used NexStar 5 in the Classifieds for under $300.00
That is all you need and more! Plus it had Go-To, and the optics are Razor sharp! I trust George (the seller) absolutely!
It is the orig. NexStar but that isn't all bad.
The main thing I hear people beat them up about is you cannot update the handset. BUT here is what you get..
The mount is built MUCH better than the new SE versions.
I have had both. The motors are so much better you cannot believe till you use one side by side! There is 18,000
Objects, ALL you can see with a 5" plus a lot invisible in a 5".
By the way I kept my 5" and sold the NexStar SE, it was so much sloppier, noisy, and not as stable!
Good Luck

Get one of the telescopes mentioned above the planets. Just use the SX20 zoom lens for your deep space shots. You will be limited to 15 second exposures with a tracking mount, but if you take lots of them they can be stacked for pictures of the Milky Way and some of the larger and brighter objects.

There is a lady on www.astrobin.com who takes great pictures with a similar camera, the SX40. Do an advanced on that site for SX40 or SX20 to see what has been done. Later you will probably want to upgrade to a DSLR.

Here are some images taken with the SX40, some directly through the zoom lens and others taken afocally through a telescope.

After some research I'm down to the meade rtx90 or the nexstar 5 se. Any comments or suggestions are very welcomed. I have one question what is meant by the f10 is it better if this number is lower or larger?

I just bought an etx 90at. It's was a demo so I got a nice discount from the dealer. From your posts you and I have similar requirements. The etx is a pretty good scope - I went with it over the 5se for a couple of reasons : first, my wife is a birder so it's more dual use than the 5se for that. For eg, add the optional diagonal and it's essentially a 90mm spotting scope also, get the t-adaptor and t-ring for your camera and it's a hell of a telephoto lens. Of course the 5se can do both of those things, but it's not as ready to go out of the box. The second reason was money -$300 for 2.5 inches is a lot.

Don't forget that whatever scope you get you are going to need accessories - I'm finding my list of addons is approaching the cost of the scope!

Couple of things on the etx90 to know : new etx90s are a bit different than many of the ones discussed online- specifically the mount has been changed - there is no hard stop home position, the battery compartment is different, there is no AC adaptor plug (basically the 90 now comes with the 60/70/80 mount). Some of this is good (finding home position) some not so (AC adaptor). Just FYI for your decision.

Both are good scopes. I think the 5SE is better, but you also pay a bit more for it. I had the previous version of the 5SE (the Nexstar 5i) and it was a great scope.

You may want to keep your eye on the used market. Both are very common scopes and come up on the used market quite a bit.

Couple options. This site's classifieds. Ebay. Astromart (costs a little money to use). Craigslist (depends where you live as to if this is a good idea...I'm a bit cautious on this where I live).

There are neither scope on Astromart right now.

Just a word of caution...it's always a bit of a gamble when buying used...so look for someone who is a quality seller. Has sold a lot of stuff in the past. Etc.

Once An Object Is Found With The Nexstar 5 SE will The Scope Continue To Follow It And Keep It In The Center? And Does The Meade Etx 90 Also Do This?

When setup properly both track objects. A nice feature.

Good choice. If I was forced to only own one scope that is what I would own.

You might also consider the 6SE. It uses the same mount as the 8SE, and the 8 pushes the capacity of the mount and can make for somewhat jiggly views at high mag. I hear the 6 is much more stable.

So it's a trade-off of aperture vs. stability. I chose the 8, and most nights I am glad I did.

Just so you know, Celestron has updated scopes coming out next month called the NextStar Evolution.

You may want to read about the 8 inch to see if it offers you things you would like. As a summary:
- WiFi controlled with iOS or Android
- Internal 10 hour rechargeable battery
- worm gears
- manual controls to move the scope

The Evolution looks to be more modern, but if it has things you don't like, or the increased price is too much, than the 8 SE still looks very good (maybe they will even discount it soon??)

WOW, Thanks for the Info.
That's great news. I compared the 5SE and the 8SE while the 8SE will get me a little better image the 5SE comes with a wedge that would come in handy when I do videos. From what I was told the 8SE does not come with a wedge. I also decided to go with a web, use RegiStax image processing software and an es 68 24mm or a 32mm plossl 52 degree. But if someone can tell me Im wrong about the wedge for the 8SE and I can use it as a EQ then I would rather go with that.
