Been looking at getting a nice refractor and today my "finance manager" said I had a $2000.00 budget.

 

Including a small shipping upgrade I came out with $41.43 to spare.

Congrats! Did you also know that Astronomics  gives CloudyNights members a discount? I believe you have to give them your CN username info when you order.

I have loved mine for the past 5 years, you will love yours too.

Do the rings on the AT130 fit on a Losmandy style dovetail plate? Does AT sell such a plate?

Thank you.

Heywood,

Yes and yes.

By the way I still use the Vixon plate. But if you want the Losmandy you can get it from lots of sources.

In a way, I would have liked the 130 EDT better--except for the weight and portability. Nothing beats aperture. You will love a 5" refractor once it's in your hands. Steve O'Meara did the entire Messier catalog with a 4" Televue Petzval   under superb dark skies of Hawaii and with his phenomenal eyesight. But that additional inch makes a big difference in quality of what they look like. More globular clusters resolved into stars, and the view of the Perseus Double Cluster will astound you!

Heywood,

 

As Roger said, Yes and Yes.

 

I just put a Losmandy "D" style plate and radius bars on my Meade 2080 SCT.

 

The plate is pre-drilled with  an abundance of smooth and threaded holes.

 

You can get the real deal here:  http://www.losmandy.com/

 

Their products are high quality and the customer service is superb.

Congratulations.  That's a great scope and you're lucky to get one given the shortages now.  I wonder how many telescopes are sitting in containers in those ships sitting in the ocean on the West coast right now?

And I hope none of those containers are floating in the ocean after that accident the other day. tongue2.gif

What's everyone using for a reducer / flattener? The matched one was more on the way when I ordered. I got a hotech flattener on hand good through about f/8 I think. Not sure I'll be doing much deep sky imaging with it however.

I'm looking at options as well. Anybody have information on what glass is used in this model? I know the 125EDL uses FCD-100 but I haven't been able to find anything other than "ED glass" for this model. 

 

John

The "pamphlet" that came with mine said, Your scope's air spaced triplet optics use FPL-51 equivalent ED Extra-Low Dispersion glass.."   http://www.ianmoriso...jective-lenses/

John,

 

It is not actually FPL-51, it is the equivalent of it though as the pamphlets referenced says, just a different glass maker which is CDGM in China. with an Abbe Number of 81.6. It has H-FK61 glass in it which the article says is very similar to FPL-51. That glass is briefly mentioned in the article you referenced. 

 

To see how good it is please navigate to Astrobin, log in and do a search for AT130EDT and look at some of the photos it has generated, I doubt you will be disappointed. I've  had mine about 5 years and the thing just never disappoints. I have never read any reviews where the reviewer indicated they were disappointed in the quality of the scope, the optics or anything. It's not a Tak, AP or Tec but its a darn good scope.

Thing to look for rather than colour with inexpensive triplets is any evidence of lens decentering/wedge or spherical under or overcorrection.

Had first light tonight.  This scope is a total WOW.  I should have gotten a refractor a long time ago...

 

I did hit a little bit of a snag.  I could not get the scope to come to focus.  Then I thought about back focus.

 

I don't have a decent extension tube collection, and I don't have a decent diagonal yet, but I do have a Vixen Flip Mirror that has a 2" tube for use with an SCT visual back.  Add the blank off cap and Viola, I have a diagonal.

 

So I slew around to Jupiter and I am blown away.  I have a 30mm to 10mm zoom,and I see Jupiter and four moons on black velvet.    I bump the power up and at 10mm I can see banding...  I grab a 2x Barlow.  At 5mm I can see multiple bands.  This is a first for me and I'm loving it.  Then I hit Saturn..  OMG...  The rings have sharp edges...

 

I spent the better part of 2 hours taking it all in.  I'm hooked...
