I picked up that Meade 90mm, F/6.7 "Infinity" refractor from Bill at Telescope Warehouse that was advertised in the CN classifieds a few days ago because I couldn't resist the $60 shipped price. I wasn't expecting much other than using it as a wide field, low power scope.  I was checking it out tonight and it does well with a 32mm eyepiece (19X) for Milky Way scanning. Focuser was smooth with no play and the star images looked pretty good.  Just for fun I put it on Saturn with a 6mm eyepiece in a 2X Barlow to get 200X and was absolutely blown away at the performance. Very minimal CA and Saturn was tack sharp with Titan and Rhea evident. I checked this against my trusty little ETX90 at the same power, and I couldn't tell the difference other than the refractor image was slightly brighter. This thing is almost as good as some expensive ED scopes I've looked through, at least on Saturn.  Has anyone else used one of these scopes and are they all like this or did I just get lucky?? If they are all like this one, the word "binocular" comes to mind!

Hi Frank,

 

I am glad you are enjoying the scope! I have the Orion BX90, same specs as your Meade, and I really like it. Portable and wider field of view, but with enough focal length to do pretty well on the planets. I have used a Meade Infinity 102 and found the false color to be too much on the planets. Seems like 90 f6.7 is a sweet spot. I am not knocking the Infinity. The one I used was well made and fun to use, just not the right ratio for me. I have not looked thru an ED scope, so it is encouraging to know that some modest achros are pretty good!

 

Enjoy!

Frank,

i picked one up as well for $60 from Bill at Telescope Warehouse.  He has a few left at that price.  Your description is spot on with what I saw.  I’m putting together a small grab and go package for friends and family to borrow, or use for kids at star parties. The scope focal ratio is a good balance between a fast f/5 and a longer f/9

 

Anyone looking for an inexpensive scope to add to their collection or to give away, this scope will be a great buy.  Just supply your own eyepiece, diagonal, and mount.  A simple homemade pipe mount will be good as well for this light scope

 

For adults looking to get a scope for kids this is a good choice

Well, my experience with the Inf 90 has been about the same - I have no complaints and was surprised the CA was as tame as it is. It's a good scope. Bill is a class act - he cares about what he ships out, very helpful, good advice - just all-a-round keen bean

AstroKerr - I agree with your comments about Bill at Telescope Warehouse.  I've been dealing with him for over 10 years and never had any problems, and have gotten some incredible deals on excellent equipment.  I just sold an ES AR-102 because of the very noticeable CA for magnifications above 75X.  It was an excellent wide field scope with a super focuser, but hardly a multipurpose grab and go scope.  It was also heavy! The Infin 90 is light and certainly works great on Saturn.  I'll be anxious to check it out on Jupiter and the moon.

Maybe I'm going to the wrong place. Can someone post a link?

It's a good idea to keep an eye on his Ebay store.  He frequently gets either "overstock" or new-old stock stuff from major vendors (mostly Meade) which he sells at really good prices.  I've got my eye on that EQ-2 mount for my ETX and that 90mm refractor I just got. My alt-az is totally adequate for sky sweeping but not for using any significant magnification. My larger EQ mount is gross overkill for both.

Maybe I'm a klutz Tony but all I see on eBay are the f10s.

Good to know re: contacting him. I may give that a shot.

It is linked to a polaris f10 90mm, your not a klutz. I looked through his ebay store, f6.7 seem to be gone.

Yeah my fault.  I could have sworn that I had picked the f6.7.  Anyway he is out of them.   Give him a call he might get more
