The Lightwave 72 ED-R F6 Refractor is a portable telescope for imaging and visual use. The F6 ED doublet optics feature an Ohara S-FPL53 ED element and Schott glass mated element, delivering high contrast elements with good colour correction. The dual speed rack and pinion focuser with a 1:10 ratio fine adjustment knob ensures accurate and easy focusing to ensure images are sharp at the eyepiece, or on your camera CCD chip (focusing is especially easy in "live view mode" on a DSLR).

Lightwave 72 ED-R Refractor: Key Features

  • Optical tube with air-spaced 72mm F6 Dual ED lens (432mm focal length)
  • Ohara ED (SD) glass in a precision CNC machined lens cell
  • Super-high transmission coating (STM Coating) on all air to glass surfaces
  • Resolving Power (Dawes’ Limit) 1.61 arc seconds
  • Visual Limiting Magnitude 11.8 maximum
  • Light Grasp (human eye = 1x) 106x
  • Field Stops 3x glare-reducing baffles inside optical tube
  • Weight approx. 2.5kg, OTA length with dewshield retracted, 32.5cm
  • Precision CNC machined components and tube made from light, tough aluminium alloy with matte powder coat. Retractable lens shade / dew shield
  • 2" "Rack 'n Pinion" Geared Linear Power dual speed focuser with 1:10 micro-focuser and 360 degree rotation
  • 2" to 1.25" reducer with brass compression rings included
  • Special mounting base with dovetail profile to fit most telescope mounts and 1/4"-20 Photo tripod threads for use with photo or video tripods
  • Tough alu flight case included, measuring 39x25x19cm. Lockable with 2x keys included

The Lightwave 72/432 ED-R refractor delivers very good colour correction, delivering the high contrast images refractor owners appreciate. The ED doublet lens system features an ED element made from premium Japanese Ohara glass. The elements have been figured with excellent smoothness and very effective super-high transmission coating (STM Coating) on all air-to-glass surfaces for exceptional contrast.

In fact, the colour rendition is so good for the price, that telescopes previously employing this same lens have been described as apochromats or "APO" by both manufacturers and their customers.*

Versatility: The Lightwave 72 ED-R is a very versatile telescope, performing very well at both visual observing and astro-photography. Detail is visible on the larger planets such as Jupiter, with both the four principle moons and main cloud belts easily visible at high power. Saturn's rings are striking, and the Cassini Division in Saturn's rings is easy to see. The Moon will reveal an hundres of craters, as well as volcanic plains and mountain ranges, particularly enjoyable when the light strikes the moon at an angle during the 3/4 lunar phase. Adding a high quality Kendrick solar filter or Daystar Quark Hydrogen Alpha solar viewing eyepiece would give you a powerful solar observing system. In fact the Lightwave 70 ED-R with it's F6 focal ratio and 432mm focal length is ideal for the Daystar Quark, allowing you to capture the entire disc of the sun at low power, enabling viewing of solar prominences and their development over a few hours. The 72 ED-R will easliy reveal structure in sunspots with a white light or Hydrogen Alpha eyepiece such as the Daystar Quark.

The dual speed "Linear Power" Rack and Pinion Geared focuser has eight adjustable internal roller bearings, so you get more "lifting power" and stability for large eyepieces or cameras. Fine tilt-adusments can be made using the focuser, allowing astro-photographers the ability to fine-adjust the optical tube to produce very round stars at this fast F6 focal ratio. The focuser can be rotated to frame celestial objects the way you want them. The focuser has a 2" rear accessory port with brass compression ring and a 2"-1.25" adapter with brass compression ring and dust plug. The optional Lightwave 50mm RACI (Right angle Correct Image) finder-scope or the Lightwave RDF (Red Dot Finder) both have a quick release bracket which fits on either side of the focuser unit. Once the quick release bracket is installed, you can leave it on, so adding the finder takes seconds.

Grab 'n go portability: The Lightwave 72 ED-R comes in a tough hard skinned aluminium flight-case with a foam insert, and pre-cut removable inserts for an eyepiece, a diagonal and Red Dot Finder, making it the ideal "grab 'n go" portable telescope-kit for visual observing or astro-photography. The case will easily fit in an aeroplane overhead locker, so you can travel with your telescope along as cabin-luggage. The case measures 39x25x19cm and is lockable with 2x keys included.

Mounting the Lightwave 72 ED-R on a camera tripod: Attaching the telescope to a photo or video tripod mount takes mere seconds by means of the 1/4" photo thread on the dovetail-base. A photo-tripod is perfect for grab and go visual astronomy, digi-scoping and use as a terrestrial spotting scope with superior astro-eyepieces. Astro telescopes usually have higher quality optics than spotting scopes costing many times the price, which is necessary for higher power magnification demanded by astronomers. They do however display a reversed, upside down image, which is perfectly acceptable for night-time viewing. For daytime use, simple plug in the Lightwave 45 degree erect image prism diagonal, which produces an upright, correctly orientated image. It's also compatible with astro eyepieces, so you can take advantage of these lower priced yet higher quality optics).

Mounting the Lightwave 72 ED-R to an astro-mount: Most GOTO mounts which support "Vixen/Synta-format " dovetails such as the iOptron SkyGuider, Skytracker, Cube PRO, Minitower range, SmartEQ PRO, Skywatcher EQ5, and so-on will fit directly. The mounting base can be detached and re-mounted facing backwards to change the balance point for smaller loads. The mounting base is slightly wider than the 44.5mm Altair TMS Mini-Vixen-format clamp required for the Sabre mount, so a correct size dovetail bar is required to use this telescope with the Altair TMS Telescope Mounting System. Product codes: VDB-CL-180 or SW-MINI-VBAR-200 are both compatible. They are attached by means of the standard photo tripod threads in the mounting base. Longer dovetail bars can be used to gain more length for balancing with heavier accessories, such as cameras and filter wheels. Visual observers might choose longer dovetail bars for balancing with bino-viewers or heavy eyepieces. The mounting base can also be completely detached, allowing the Lightwave 72 ED-R optical tube to fit guide scope rings, such as the Altair TMS Lightweight Rings (code: GSR-100), or the Starwave 110mm guide scope rings (Code: SWGSR-110). Both systems have many options for mounting piggyback, or side-by-side.

Note: All applicants will be subject to a credit reference check by the lender.

Credit is subject to application and status. Warehouse Express Ltd trading as Wex Photographic act as credit broker and not the lender. Barclays Partner Finance act as the lender.

Can I repay early? If so how?

No repayments are scheduled in the initial six-month deferral period. However, it is possible to pay off the loan, either by way of a lump sum or in smaller amounts. If the loan is fully repaid within the six-month deferral period, then no interest is payable, but a £29.00 early-settlement will be incurred. Such repayments may be made to Barclays Partner Finance by cheque, debit card or standing order. Unfortunately it is not possible to set up a direct debit within the deferral period. Further information on how to make such repayments will be set out in the loan agreement pack provided by Barclays Partner Finance.

What happens if I don't repay within the first six months (deferral period)?

Following the six month deferral period, Barclays Partner Finance will initiate a monthly direct debit payment for the remaining duration of the loan. Interest will be charged at a rate of 19.9% APR on outstanding balances (backdated to the first date of the loan). Late payment penalties and early repayment charges will apply from this point. Barclays Partner Finance will send a reminder letter approximately one month before the six month deferral period is due to elapse. Note: If you chose to spread the cost and pay monthly, interest is charged from the start of the loan, not from the start of the repayment period.

What will I receive from the finance provider (lender)?

Barclays Partner Finance will send a loan agreement pack approximately four weeks after delivery of the goods, confirming that the account has been activated and, from this point, it is possible to make repayments against the loan.
