new offerings from Stellarvue

#1

Post by notFritzArgelander »


New headaches in my email. :)
Stellarvue SVX127D
Five Inch f-8 Doublet Apo
Imagine a .99 Strehl 127 mm apo doublet refractor with a lens figured as accurately as our SVX triplet apos. We plan to have these telescopes rolling out later this year. We are making only 100 of these exceptional refractors. They come with a 3" focuser, visual adapters, dual mounting rings and our optional C130 case is available.
Stellarvue SVX102ED
With our advanced capability of producing .99 Strehl optics in the 102 mm size range we also plan to produce a 4" doublet as the perfect introductory refractor telescope for those on a budget. We are doing this to create the most consistently accurate 4" apo doublet on the planet using the lowest dispersion glass available.

Just think, 10-15 years ago we would have been wishing to have these kinds of choices! :D
Both doublets at 0.99 as well. I remember when Roland was being outlandish and guaranteeing 0.984 with his refractors.

I have room for one more refractor, maybe. ;)

I'm not sure I could pick the difference between 0.984 and 0.99 visually. ;)

BTW not_Fritz: do they say if this is polychromatic Strehl? Or over what wavelengths?

It will be interesting to see the prices for these new doublets, and how they relate to the Tak equivalents: the current price for a SVX102T delivered to my door would be approx. 40% more than my TSA102 cost me; that was a few years back obviously, but the current prices for the Tak FC100D series through our Oz dealer are still less than I paid for the TSA...
Telescopes: 12" f5 dob, Celestron CPC800, 150mmf5 Celestron achro, Tak TSA102, TV76, ETX125...
Binos: Steiner Wildlife XP 10x26, Swarovski 8x30 Habicht, Zeiss SFL 8x40, Vanguard Endeavour 10.5x45, Fuji FMTR-SX 10x50, Tak 22x60, Orion Resolux 15x70
Eyepieces: way too many (is that possible?), but I do like my TV 32mm plossl, 13mm Nagler T6, 27mm Panoptic and 3-6mm Nagler zoom, plus Fujiyama 18mm and 25mm orthos and Tak 7.5mm LE

Likely not. I think that at the high end a difference of 0.04 Strehl would be discernible but the difference between 0.99 and 0.984 is only 0.006.
BTW not_Fritz: do they say if this is polychromatic Strehl? Or over what wavelengths?
They don't say, but I'd guess that this is monochromatic at ~555 nm based on my experience with my SV ED80.

I only have a projected price for the SVX127D at 2495 US$. The Takahashi TSA120 is 4430 US$.

The Tak FC 100DC is 2230 $US. I don't have a price estimate for the SVX102ED but expect it to be considerably lower. The fact that the focal length is not mentioned (nor is the f ratio) leads me to suspect..... something that I am going to keep to myself until better informed. I had been eyeing the TS115 f7 triplet as the last refractor.....

TS have have a great price on that at the moment!

(..."last refractor"; who are you kidding? ;) )

Happy dreaming,

Triples are the way to go.
Had the apm 6" f8 edapo and it was only so-so. A 5" W.O. triple is better on planets.
The sw 120 f7.5 was really disappointing. The ts 115 triple with dash 51 glass is noticeably better.

The hi end Taks and Vixens are really good as doublets , do not think anything cheaper will match them.
Arizona- where the sky's are not cloudy all night.

Triple lensed fracs are so yummy when looking at planets.

Certainly for astrophotography a triplet with a good polychromatic Strehl is better. For visual.... it depends on other factors. The optical accuracy is more important than the number of elements.

I think the Stellarvue are in the same class as Takahashi and Vixens, the Strehl ratio is a good indicator. I have not had any extensive observing time that I recall with them but I have had extensive use of 5" class apos from Astro Physics and Zeiss. My SV ED80A doublet is the most perfect OTA I have ever used.

I've had the SW/Orion ED80 and 120s and my samples were fine. The 80 Orion is still in the family and is my younger daughter's principal scope. I was less pleased with the 120s.

My main reason for preferring a doublet is that I don't trust myself with the collimation and maintenance of a triplet. I wanted to get a Tak Steinheil fluorite doublet before I retired, but that didn't happen.

Excellent! I was suspecting that they would come back to APO doublets sooner or later. With success of Access line they would be foolish not to.

IMO for visual 80-100mm doublets offer distinct advantages over triplets: faster equilibration time, less weight and easier to balance. I have/had both triplets and well executed doublets in this range and could not tell difference in image quality for visual.

For 120-127mm range ED doublets other than Takashi it seems the feedback is that they are more of reduced CA than true APO, even for visual.

I am curious to see how Stelarvue version would behave.

Since I acquired the TS 102mm f11 ED and find it superb optically the SV 102ED doublet of unspecified ratio might not be interesting. The 127 is a temptation. I need to take a Ronchigram of the TS optic.....

My SV102ED Access is a gem. I don't believe Stellarvue would low the bar on the next SV102ED. :lol:

Still, the scope I have checks all marks on my list, no reason to trade it.

I had ES 127mm triplet for awhile. Optically it was a nice scope. At that time we lived in a small condo and I had a strict limit on the number of scopes. Had to sell it to get 9.25" Edge. I am happy with the Edge, but was sad to let 127mm go.

Now I have a whole room to store my scopes, but our finances are tight after purchasing the house. Once we sort it out I do see 5" or 6" APO in the future.

Yes, that sounds like a good plan. :) I hope to find a suitable fixed location so I can finalize my set up.

If you can make this happen definitely go for the dark sky location. I had to be sensible about needs of my family, so a tiny bit darker sky. :lol:. On the positive side I have shorten my trip to the dark site by ~30 mls and eventually may acquire or build observatory there.

If you can make this happen definitely go for the dark sky location. I had to be sensible about needs of my family, so a tiny bit darker sky. :lol:. On the positive side I have shorten my trip to the dark site by ~30 mls and eventually may acquire or build observatory there.
Family requirements are that I be within a 4 hour drive of Salt Lake City. Plenty of dark sites in that radius including Mr Shorty's Wasatch plateau observing location and then there's https://www.darksky.org/our-work/conser ... es/torrey/

It is really great to look around in the 2021 Candy store.
Bit off topic but nice to read:

Coincidentally today I was looking in a "build it yourself" book from 1950. A book from my youth. Interesting to see how enthusiastically was written about 50mm lenses for a telescope. Most pics were 50 mm telescopes and they were ACHROMATS! Prices of lenses far beyond the reach of a normal human beeing. How exited I was when I finally bought my own 60mm!
What a tremendous achievement we've made in the quality and prices of amateur telescopes.

Here's one of those pictures of a home-made telescope. ( copyright was given )

You're own project published in a book, very gratifying, I'm sure.

It is quite amazing how things have changed even from the 80s-90s where if you had something like a 80mm+ Unitron/ Polarex you were in a completely different class than the average observer, If you were observing with a Zeiss you were rich!
Most eyepieces were 0.925" or 0.965", 50° AFOV eyepiece were considered widefields.

How times change!

I thought I'd never do this, but I just sold my FC-100DL and put a $500.00 deposit on the SVX127D. :-)
