Meade 70AZ-USB Telescope with USB Color Camera

This product is a good telescope for beginners with the ability to view thru the eyepiece some very nice shots of stars and the Moon.

It comes with the camera and USB cable and software.
However, it does not have the ability to see stars thru the camera.

I first focused on a bright star in the south. I then switched the lens to the camera with all software up and running. No star. So I made micro focusing adjustments. No star.

To double check what I was doing I focused on a street light about 1,000ft away. I was able to get a grainy view of the light and pole in focus on the computer screen. I adjusted exposure to many different settings and got many different views.

I repeated these steps several times with bright stars and got nothing as if the camera can not see.

Is it possible that the supplied camera is too weak for star photos?

I have been practicing stacking pics on PS and am getting the hang of it.

I will keep trying. I tried to use the camera(Sony) thru the EP but could see an image.

What is your guys guess as to why I can see the streetlight but not the stars?

Thanks, Rich

Well, it is 3:45am Central time. I had to get up 3 times because the Moon rose right in front of a tree!
It took 2 hours to clear the branches!

I began getting a picture on the computer of a white fuzzy ball. I focused and focused until I got some shading. Then I could not focus anymore...

Then I remembered exposure and went into the options file of the software and set the exposure to 0.
This enabled me to get better focusing...

Once I began to see craters that were still fuzzy, I remembered that over magnification isn't always good. Thru the 25mm EP the view was great with the 2X's Barlow, but not the same with the camera. So I removed the barlow and refocused on the moon again. Now I am impressed with a scope that costs $60 from Walmart!
These pics are crazy! I just wish I could see stars with this camera!
Check out my best work at 3:30am...

Nice results.
The higher up it gets in the sky it should look a bit nicer.
Higher magnification needs great steady skies.
Congrats on your first images.
Aslo as for stars remember this is a web cam based imager and most stars are to dim to see.
Even the brighter stars may not be seen even if you have the maxim exposure time set,
This holds true even with the best un modified web cams.

Thanks Mark.

Is the DSI III cameras and this one...

also unable to see stars?

Also, is a larger telescope required to view planets like Jupiter and Mars?
Something like an 8 or 10" scope?

as they will be hosting a Starry Night event at the local Children's Museum. I hope the skies are clear.

The DSI III will do anything you want it to do.
It will go long exposure to bring out dim nebula and it will go short exposure for planets and lunar.
The DSI PRO III is all I use here and it is a nice imager.
As for the other camera you posted i cant say as ive never used 1.
You could also look into a DSI PRO II which is also a nice camera and Ive captured many images with it.
If you want to get any good detail on planets id recomend at least an 8 inch.
The LX90 8 inch is a nice scope for everything.
It all depends on what budget you have.
Budget is the main factor for many when thinking of making a csope purchase.
The LXD 75 8 inch is also a nice scope that is on a GEM mount.
Figure out a game plan with a budget and let me know I can point you in a few directions.
The main things in this hobby are
Are you serious?
Budget?
Imaging or plain casual viewing?
Portability?
Figure these few things out and let me know.

I will do more research and consult back. Thanks

I could not figure out how to take 10 images for stacking but now understand run a video and not take snapshots.
Then download video to registax from my PC to downloaded software and extract best frames and stack those after alignment.

This will take time to learn. My next lunar pics will be stacked, so we will see. They will be in  a few weeks.
