I am about to pull the trigger on either the Stellarvue Access 80mm Super ED $699 or the Sky-watcher Pro ED 80mm $649.  It will be for astrophotography use only.  I will be using a dslr.  These are both doublets and both have FPL-53 glass.  The difference I see is the SV is f7 and has a 2.5" focuser and the SW is f7.5 and has a 2" focuser.  The SW comes with a diagonal and fiberscope also. I know it comes with ex's but I already have those but you can never have too many of those. ;)

 

 Cost wise if add a finder scope to the SV (as I already have a TV 2" diagonal ) the costs are about $100 more for the SV.

 

Am I wrong to assume that my current TV diagonal will fit the SV?  

 

This will be my first entry into imaging.  I will be doing it with my wife who is a pro photographer so she understands the technical aspects of the camera, but she also understands that land/portrait photos are not deep sky.  We plan to do planetary and so's.  I will use backyard  eos.  A very experienced friend of mine suggested the SW as it comes with the accessories and both scopes are Chinese made.

 

For me there is a lot of favorable reviews for both, especially the SV's.  It seems people either love them or hate them.  I know there will some trade-offs imaging with a doublet vs triplet but it seems like a good place to start.  Look forward to your opinions and any other suggestions.

Owners of the SW models often feel the need to replace the stock focuser.  I am visual only and I replaced the focuser on my SW120ED with a better performing GSO model.  There are instructions on the web for adjusting the SW focuser, but I was unable to improve mine by any adjustments and ended up replacing it.  Your TV diagonal should work fine with either scope.  My vote would be for the SV.

It's a fairly small difference, but it favors the SV.  A bit faster, a bit better focuser.  SV, in my opinion, has excellent customer service, sometimes the owner, Vic, picks up the phone.

 

The F7.5 is a lovely lens that I used for starting out in AP, but the SV should at least match it, they learn how to do this better over time.  I just can't see any reason for going with the SW.

 

You'll want their matched reducer/flattener.

SV makes a very big deal about their customer service, that's been known to rub people the wrong way.  Not sure how many SV owners are dissatisfied with the scopes.

 

I own an SV70T and an SV100Q, like them both.

You would need to replace the SW focuser for photography.  The SV focuser has a very good reputation.

Go with the Stellarvue. Way better focuser.

I would spend the extra $200 and get the SV70T. For imaging a triplet is a better choice. In addition it is a little faster at f/6. I own an SV70T, and SVR102T, and an SVA130T and my favorite is the 70! With the dedicated reducer/flattener I am imaging at a FL of 336mm at f/4.8. Image capture time is reduced significantly.

 

The 2.5" SV focuser is a joy. Unless I have an extreme temp swing throughout the night, I set the focus at the beginning of the of my imaging run and never touch it again that night!

I would get the Setllarvue.  You will be happier. Better focuser and optical quality.

The ES 80mm F6 is only $30 more than the SV and is a Triplet with a Diagonal included.

If you don't need the Diagonal, B & H offers it for $699 with a 1.25" Diagonal (I'd personally go the extra $30 for the 2")

It will be heavier than the other two but something to consider.

The Stellarvue! I currently have the A102mm and am very pleased. It is my third Stellarvue scope and I have always been a happy camper! And true, I have called before,and had Mr. Maris pick up the phone directly. Each telescope is tested before it goes out.

I'll add my voice to say the Stellarvue focuser is better sized for photography. If that's what you want to do, it's a no-brainer when deciding between the two.

I ended up getting a used stellarvue 80a for $600 incl a diagonal, case and two eyepieces.  I ordered the flattener for it and  now the adventure begins.  My wife and I are looking forward to it.  I downloaded backyard eos and it connected right up to my 7d, so I hope that is a good indicator.  I have considered building an altar in the backyard for sacrifices but my wife said our home owners assoc says that is a no-no.  ;)

I have the Vixen version of this scope, the Vixen ED 80sf. Came with a single speed crayford. I replaced it with a GSO 2 speed. It’s a very nice lense!
