Hello all,

 

New to the forum, and new to my recently acquired Meade DS-125AT, which from what I understand was the Brookstone model of the Altazimuth Maksutov-Cassegrain Telescopes. 

What is the consensus on this scope? anyone own one/have advice for a noob like me?

 

Just picked it up this afternoon and was hoping for a clear night for the full moon. Unfortunately though mother nature was not so kind. Overcast up here in CT

 

The scope was purchased as a gift for my grandfather 6 or 7 years ago, it sat in their home and has collected dust ever since, until I decided to rescue it and point it upwards once again. 

 

The scope has a few issues with it. the L-bracked arm is pulling away from the gearbox causing the whole scope to tilt a few degrees, puled it apart and tightened everything back up, still tilting, I figure its just from sitting on the tripod for years.

Two of the viewfinder screws have been snapped off, no idea how or why that happened, but it doesn't seem to hinder the operation of the scope (I was able to aligned both the 25mm viewfinder and main scope.

 

I am looking to do some astrophotography, I've been a traditional photog/videog for a few years now and have done everything from underwater to GoPros on the tip of aircraft. Figure I could scratch my stargazer itch and photog obsession in one go :)

 

How do I go about attaching my Canon 5DMkII body to this essentially giant lens? can someone point me towards an adapter? 

 

My main confusion is eyepieces. Where do I begin? What brand/size/style? I believe this scope accepts .965 and from what I hear thats not the industry standard. Most amateur scopes support 1.25 barrels yes?

If I were to do shots of say, the moon, what eyepiece would I use?

and i'm assuming if I invest in high quality eyepieces, I can take these to say a better scope in the future?

 

Sorry for my noob questions, figure I would go to the forums and ask experienced stargazers. 

 

Thanks all, I look forward to your responses :)

-Ryan

Hello, Ryan!

 

Welcome to the forum!

 

I am not sure about the mount, but the optical tube should be good.

 

If you could post some pictures of the scope, it would help determine what can be done with it.

 

There are a number of versions of the AutoStar Mount around.  The two newer versions are good to work with.  Previous to that....well....there really aren't any old ones left to scavenge parts from as far as I know.  Posting pictures will help me determine what can be done.

 

As far as eyepieces go and astrophotography, you will have to get away from 0.965 eyepieces if possible.  If your scope uses the smaller ones, you will need a different adaptor to use the 1.25 inch.

 

Best Regards,

Is this a DSX-125AT? I have a DSX-90. This is the ETX-90 telescope on a DS-2000 mount. The performance is nearly identical to the ETX, which is adequate for visual, but only basic imaging. The telescope should use standard 1.25" eyepieces and you might look at vendors like Orion or Astronomics for a basic set of economical eyepieces like Plossls. You can download a manual from Meade's web site. Also, Mike Weasner's Mighty ETX site is a fantastic archive of information on the ETX and DSX telescopes.

Thanks, John!

 

I keep forgetting about Mike Weasner's Mighty ETX site.  It is truly a wealth of information.

Yes, it is a DSX-125AT, I missed the "X" in my initial post. 

Just ordered a .965 barlow lens (just to have) and a T-adapter for my Canon 5DmkII. Still researching camera adapters for this particular scope. Anyone have any ideas?

 

I'm working on creating a .965 to 1.25" adapter CAD model that I can print on my 3D printer. I've printed out a few test models and so far they are looking great, just waiting on a 1.25 eyepiece to be delivered so I can test it out and put my stamp of approval on it. 

 

Here is a Canon 5DMkII to .965 adapter I made just for laughs to see if it would work. With a little sanding, it fit pretty darn perfectly.But I can't really create the fine threads with this material (and trust it supporting my $1,500 camera)  

 

Thanks for your replys. I'm happy to say I took my first Astrophoto the other night (with my cell phone) but still not a bad first effort.

Also, JohnGraham is right, I can confirm that my scope does utilize 1.25" eyepieces.... now I know :)
