Well, just ordered onecrazy.gif . This will be my fourth 102mm refractor. I will have to let one or even two of them golol.gif . I just bought a AT102ED a couple months -ago. russell23- you're a bad influence!!!waytogo.gif

I let go my WO Z61 and SV80 Access over the last few weeks in preparation for possibly this purchase.  I think there will be a lot of 100-102mm APO's on the market for people looking to pick one up used.

I just received an email from Stellarvue. They stated that because my recently ordered scope will take a little while to get ready to ship- they offered me a choice to up grade to a "carbon fiber" tube for only an extra $100.  Is it worth the $100 for the carbon fiber tube? I've never owned a carbon fiber scope. Any opinions are appreciated, Thanks.

I got a similar email from Vic and immediately pulled the trigger. Do it and don't look back!

Lighter weight. Some like the looks of carbon fiber.

It is a bigger issue for imaging newts. For refractors the main advantage is weight. Could make a difference if you are trying to get by with a Twilight I, Porta II, Versago, etc.

I'm using a newly acquired AZ-GTi with an AT102ed right now, and while very usable, it is pushing the boundaries of the mount. Shaving the extra weight while switching to the SV102A is going to be icing on the already delicious cake.

What are the advantages besides weight?

I went for the carbon fiber- it definitely will be different!

For refractors it is just really weight. Possibly looks if you prefer the look of CF.

Ultimately if CF was clearly superior to aluminum, don’t you think Televue and TEC and AP and Tak would come in CF?

CFF sells premium aluminum scopes

And premium carbon fiber scopes

I had a couple of carbon fiber APO fracs. Liked the lighter weight and look, but also had a few concerns.

 

The carbon fiber tube walls are very thin, easier to dent. Also I don't know if they get brittle and crack with age.

 

Carbon fiber tube is connected to the focuser with aluminum collar. The collar is either glued or bolted to the tube. In both cases the connection seems less secure compared to the aluminum tube. On my ES 127CF the screw holes were just 3 mm away from the tube edge. Since the holes are in plastic I suspect they could stretch with time from focuser/accessories weight.    

 

Finally, I suspect that the tube may flex under the focuser/accessories weight.

Here is Stellarvue’s own take on carbon fiber vs. aluminum.

I think I will stick with the Aluminum based upon SV’s info.

Well, I couldn't resist. I tried but I'm weak. I just submitted my order.

 

The thing is I just recently purchased a William Optics GT71 w/flattener and guide scope. A 102mm refractor, hell any 'scope, wasn't (isn't) really in the budget. I planned on using my C8 for visual and the GT71 for imaging with a little visual thrown in. But now I don't know what to do. Do I sell the C8 and use the 102 for visual instead? I guess I'll have to compare the C8 to the 102 and see which I prefer.

 

Decisions, decisions.

Hey this may be a little off track but is a 80mm ED good for visual ?

Keep both. Use the 102 when you don’t feel like the comparatively narrow field of the C8.

A 4” inch refractor and an 8 inch SCT compliment each other very well. It’s my set up smile.gif

I have been lurking in the classifieds looking for an upgrade from my 2003-ish Orion ED80 and when I saw vic's ad in that other online astro classified site so I jumped on it.   I had noticed that they discontinued the line a week or two ago and was kind of bummed as I had been planning to get one of these as soon as I had an "extra" $1,100.   At this price it was a no brainer!

 

I have a question for those of you with experience with this scope.   I upgraded my ED80 with a Moonlite focuser so I could do autofocus in SGP.   While I love the focuser, I do think that the crayford design does slip a bit sometimes - especially at the zenith.   How is the R&P on the Access 102?   I have heard it is good, but while I know it is not a feathertouch, can it produce good repeatable results without a ton of backlash when changing directions?

 

I also wonder if there is a good bracket for a stepper out there that anyone can recommend?

Well in the last two weeks there have been a couple of tempting refractor choices I’ve been able to resist.

AT102ED with glowing reviews, get one before they’re sold out. Able to resist, check!

AT92EDT 2-day sale at $300 off. Able to resist, check!  (Barely)

SV102ED Access blow out sale at $400 off, not so much, I’ve sinned, ha!

I placed a phone order around 4pm to verify they still were available, and bought it and the case. Poor Vic was a busy busy man, I don’t think he had any idea of the amount of sales he was going to generate in such a short time. lol.gif 

I’ll probably only be able to look at it for the next 6-8 weeks until the monsoon season ends here. If it lasts until winter I apologize in advance. Congrats to all who have purchased one of these, should make a mighty fine GnG set up!

Best regards,

Karl

Cheers,

 

I've been a "reflector guy" for nearly fifty years but ... uh ... the SV125 checked a number of good boxes for me, in no particular order:

 

(1) high likelihood of very good optics (poly Strehl > 0.95),

(2) about the biggest "grab and go" visual scope I might handle someday in my dotage (my current lift is 67 lb deadweight to load my superb 10" Newtonian onto its mount),

(3) also good to "grab and go" for a quick look outside at planets and brighter DSOs,

(4) excellent quality glass means essentially no CA while observing visually,

(5) can use minus-violet or deep red cutoff for imaging someday if the bug bites. So far, price and Bortle 6 skies in my backyard have been good bug repellent, though,

(6) large enough aperture for brighter deep sky objects and plenty of resolution for planets under most local seeing conditions,

(7) unlike some other makes, focuser quality and fit-and-finish are first rate,

(8) can be easily transported in my car to remote observing sites (UNLIKE my 10" and 14.5" Newts, which are "transportable" only with difficulty in my small sedan), and

(9) not least, the price ($1,495) was unbeatable for a new 5" ED-type OTA.

 

Yea, like the last poster, I too have sinned today (grin). This will be my first new-in-the-box telescope.

 

Happy observing always,

 

Don

And I just received the upgrade to carbon fiber email. To which I replied in the affirmative. I also added the quartz diagonal.

I may now be poor, but at least I can spend my nights, the clear ones at least, being entertained.

I may start looking for a part time job to support my astronomy habit.

Yes, I have scopes from 80mm to 8" and 80mm still gets a lot of use. Larger scopes obviously will show you more, but if conditions are iffy, or you don't have much time, or don't feel like setting up big guns I just grab my 80ED with Mark IV zoom and go. It reaches quite deep under the dark skies. 

 

Works great as a travel scope and can be used comfortably on a photo tripod. Also perfect match for AzGTi goto mount.
