Since each lens element is permanently held in place, the retainer applies less pressure on the lens, eliminating optical pinching
/ distortion.
Stellarvue cells have proven to maintain alignment better than
mass produced non adjustable cells, especially when the telescope is jarred.89mm OD main tube, 103mm OD dewshield. OTA is 435mm long, 500mm with dew shield extended. Weight 2.7kg.

APO Refractor (Order
SV90TBV) 
 
|
Stellarvue spent three years designing what they consider to be the ultimate grab and go telescope. This telescope is as light and portable as an 80mm short tube, yet it delivers 90mm of full apochromatic performance, with 1.27x more light grasp and resolution in a similar size
package. To ensure excellent colour correction, contrast and a perfect star test, Stellarvue chose an APO triplet design using a Fluorite centre element. The OTA is designed to work with a Binoviewer, featuring a two section tube. Remove the rear section,
for Binoviewer mode. Highly rated by users, handmade one at a time in Auburn.90mm F7 OTA
Deluxe Package:
- Dual speed Feather Touch focuser, refractor brake, 2" compression ring, 1.25" adapter

M64 Galaxy, SV102ED, Starlight Express SXB-H9
 | Probably the best value vs. quality refractor telescope package we've had - but don't take out word for it, please read the reviews opposite. Stellarvue do not claim this scope to be a true APO, but rather an ED doublet with excellent colour correction. However it features better colour correction and optics then "APO" scopes we've tested, and in most situations colour aberration isn't visible. Visit our shop in Norwich (or our observatory in East Sussex by appointment) for a demonstration. order now >

SV4M 102mm F6.4 ED Oil Spaced APO Triplet (Binoviewer Ready, "Deluxe" version)  "I always begin by performing a star test....both out-of-focus images were identical, proving the SV4's optics are superb.....The SV4 is one of the finest apochromatics sold today. If you purchase this scope, it will give you years of satisfaction, whether this means travelling to your backyard or flying half way around the world." Phil Harrington, SV4 ED triplet review in Astronomy Magazine, October 2006" | The SV4 102 comes with a 2" Feather Touch Crayford focuser, clamshell mounting ring with dovetail base, F2 multi-reticule reflex finder, finder base and C12 aluminium case. It has a two part main tube, allowing you to unthread the rear section and use binoviewers, without the need for optical correctors. The SV4 triplet lens uses a very high homogeneity Super ED glass. 3 elements result in a flat field, highly corrected, air-spaced triplet optical design that is free of zones, eliminates secondary colour, astigmatism, coma, spherical and higher order aberrations. FMC coatings are used on all six surfaces enhancing light transmission and contrast. The lens will perform on par with any high end instruments on the market and visibly outperform cheaper mass-produced
optics.

 | SV5S 127mm F7 ED APO Triplet (Oil Spaced with Pearl White tube colour)
We could go on about the incredible planetary images this scope can deliver and it's high contrast wide-field deep sky performance, but why not see what other Stellarvue owners think. Featuring Stellarvue's amazing 5" f-7 oil spaced objective. This optical tube assembly comes with the rock solid Feather Touch dual speed 3.5" focuser with 2" and 1.25" adapters, deluxe CNC dual mounting rings, retracting dew shield, oversized 6" diameter tube with deep, spherical shaped baffles for the highest possible contrast, aluminium covers, and hard side case. The telescope comes in a lustrous pearl finish. Deluxe F2 finder and base is included. The focuser is mounted to the OTA with a knurled ring that allows the owner to remove it. The tube assembly is then only 21" long, fitting well within an airline sized travel bag. We try to keep at least one of these premium scopes in stock. If we don't have one, a deposit will be taken when you order. This will place you on a waiting list, and the balance will be due when your telescope is finished. - 5" F-7 fully multicoated, hand figured, oil spaced, Apo triplet
- Spherical shaped, knife edge baffles for improved contrast
- 3.5" dual speed Feather Touch focuser with 2" and 1.25" adapters

| Objective | 127mm 5" clear aperture, 889mm F7 focal length, super ED, fully-multicoated, True Apochromat, Oil Spaced for high contrast. | | Lens cell | Temperature stable, push-pull lens cell with front adjustments | | Tube engineering & Light Baffles | Alcoa 6061-T6 Aluminium tube, lathe turned for accuracy and weight reduction without flexure. Powder coated exterior with special textured, ultra flat black coating inside for high contrast. CNC generated spherical light baffles with knife edge installed according to the minimal baffle method to reduce reflection without Vignetting. | | Dew shield | 7" diameter X 12" length. Dew shield retracts over main tube. Uses a lock screw with internal compression ring to maintain "squareness" when extended. | | OTA Dimensions | 21" with focuser removed in airline travel mode, 28" with dew shield retracted, 36" with dew shield extended. 6" Tube Diameter | | Mounting Rings | Hinged, CNC machined aluminium with rubber grip on knob, five threaded 1/4-20 holes top and bottom. Black anodized finish. | | OTA Weight | About 9kg / 20lb. (Aluminium tubing is sufficiently thick enough to eliminate flexure. Thinner tubing would be lighter, but could degrade performance). | | Optical Performance | True apochromatic performance. The objective provides a wide, flat field, perfect star test and no false colour whatsoever. Rapid cool down time. Extremely high contrast full multi-coatings result in exceptional high contrast performance both visually and photographically. | | Mechanical Performance | 3.5" Feather Touch Focuser provides smooth, backlash and flexure free motion with adjustable tension mechanism. Will lift all eyepiece/camera systems commonly employed, will operate with binoviewers without optical correctors and operate in normal single eye mode with provided threaded extension. Ideal for imaging. | | Case | Wooden Display Case as standard, or optional Transport Case |
