Hi all:

I'm looking to purhase either an astrotech 72, wo megrez 72, or stellarvue 70ed to use as a travel scope/widefield scope, finder for my 12" dob, and occasional astrophotography. Any suggestions, recommendations, or personal experiences with these scopes you could share with me?

Thanks,

Joe

I would buy based on a price. I think optic is more or less the same.

Since its going to be used for widefield/finderscope, get the one that has the shortest focal length, and throw in a lens which gives you the widest TFOV.
Optically, they will all be on par with each other.

Thanks for the replies so far. My main question is performance differences between the scopes. I know that all stellarvues are hand figured and personally tested prior to shipping. I don't know that the same is true for astrotech as there is nothing specifically stating that on their website. I don't really care about the price difference b/w the scopes, if there is a slight edge for one.

Thanks,
Joe

I believe there are differences in the focusers. I have the SV70ED and have been very pleased with the performance of the focuser on it. I can hang a 2" diagonal and a heavy eyepiece on the small scope with no problems. Very smooth and the two speeds work great.

Every AT refractor is tested prior to shipping.

Joe, we have a SV70 and quality of this thing is quite surprising for the cost. Nice glass and great focuser.

SV might star test every one but and they may be hand figured but they are hand figured at the factory - not at SV. It's the same factory that puts out all the similar one's you mentioned.

I used to own an SV70ED and can vouch for its quality. The focuser is rotatable and is very solid despite a fairly long drawtube travel distance. It also has a nice, solid screw-on aluminum dustcap for the objective.

You may want to check out Orion's EON scopes . I have the 80 mm and it is sharp looking , very well made and gives outstanding views . My neighbor has the Stellarvue 80mm and the two are very comparable .

All my Astro Techs have been A-1. Highly recommended.
From Vic Maris himself I know the SV70 has the best focuser of them all.
I have no knowledge of the WO, but assume it is comparable to the others optically.

Hi Joe,
As a finder on your dob you're gonna need at least 10 pounds of counterweight. That's if you're mounting it on the upper cage. I've done this with many small refractors including a TV 60 and the extra weight makes a fairly big difference in the dobs motions.
