    Product Description

    Whiter and brighter images. Entirely put, that is the benefit the Everbrite mirror coating. This exotic, dielectric, nonmetallic coating is 99% deliberating across the full visual spectrum, resulting in the "whitest," most natural image at one's fingertips. The coating is painstakingly applied to Pyrex with a surface accuracy of a 1/10 signal flatness. The Everbrite is offered in both 1¼" and 2" models. The diagonal bodies of each are machined from stout blocks of aluminum. In this way we can insure permanent alignment. The one piece fullness construction also assures heavy accessories can't force the diagonal body to "unscrew" from the drum as with other brands. Both the 1¼" and 2" models feature brass clip rings, anti-reflection threads and 1¼" and 48mm filter threads singly.

    Product Details

    • Latest Version, Accepets the T-Ring Adapter
    • Flexible for visual and imaging with all types of telescopes and eyepieces. Essentially Parfocal, and with nearly constant magnification regardless of image distance behind top surface (except 5x model which increases 1x for every 35mm of image distance increase).
    • Telecentric operation (field rays leave parallel to optical axis, unlike Barlow lenses which diverge rays). This is ideal for Hydrogen-alpha filter use such as with Daystar models.
    • Vignetting, edge field aberrations and pupil movement - all introduced when using Barlows with long focal length eyepieces, are minimized.

    Product Description


    The Televue 5x Powermate is opposite from a traditional Barlow lens because it has a 4 element lens design (Four Plate glass Elements) that delivers full field sharpness with virtually no aberration. The Televue 5x Powermate will sell more than any Barlow lens because the additional lens elements within the Powermate majority.

    The Televue 5x Powermate is the choice individuals that wear eyeglasses because it allows you to accomplish observation at high magnifications while providing exceptional eye relief at the same ever.

    The Televue 5x Powermate has a 1.25" barrel and stands less then 3.8" preposterous. The Televue Powermate is threaded to accept all types of 1.25" filters and is adept for both visual observing and imaging. TeleVue makes Powermate T-Give someone a ring Adapters (TLV-PTR-5126) for close coupling to cameras and CCD Imagers.

    The Televue 5x Powermate is 0.55 lbs and comes with a full 5 year commitment from TeleVue.

    Below is a quote from Televue's founder Al Nagler:

    "While Barlows are potent tools, the negative element defining them also limits their ability. The frank negative element Barlow increases eyepiece eye-relief. With direct focal length eyepieces the effect is negligible. However, on long centred length eyepieces the exit pupil position moves well beyond the schemer's intended position, resulting in vignetting with many eyepieces. This is why "Shorty" Barlows in specifically, with their strong negative element often vignette and degrade long blurred eyepieces. My 4-element form picks up where the Barlow concept can go no further. Powermate is a technically unlimited solution, using a positive field lens to redirect realm rays. The result is an exit pupil that stays where the eyepiece deviser intended. With freedom from aberrations, greater magnification potential, and thick size, I hope you'll agree Powermates and raises the standard for representation amplification." - Al Nagler<

    Product Description


    Starbeam's unrivalled flip mirror feature provides comfort and flexibility for viewing at any standpoint from straight through to 90 degrees. Viewed straight through, you see the natural sky with a 10 arc-blink (1/3 Moon diameter) "red-star" showing your scope's disposal. When your scope is pointed high, flip the mirror into position for more contented viewing. Viewed this way, the sky orientation matches a refractor or SCT's image. The assay, color and adjustable brightness of the "red-star" makes it easy to see against any gloomy to dark sky background. With its 39mm aperture, the projected image is easily seen any haughtiness behind Starbeam, whether 2 inches or 2 feet! The finely made glass lens acts as a beamsplitter to mingle the natural sky background with the superimposed red pointing "star." The first lens top acts as a collimating mirror so the "red-star" stays stationary against the sky qualifications regardless of how it is viewed. It's 6-arc-minute accuracy over any eye position allows you to pin-in the matter of objects.

    Best way to collimate my Skywatcher Dob? - Stargazers Lounge

    I've not even unpacked it yet and i'm already opinion about collimation! For starters I have the audacity i should get it set-up and have a look through it although what is the overcome way to evaluation the collimation of the range, the rout way to collimate it, and what is the unsurpassed medium to do it? I'm a probationer with regards collimation so guidance from the rudiments up would be much respected.

    Stephan&#39;s Quintet and other 12-inch targets - Stargazers Lounge

    To start, though, I ticked off some DSOs in Aquila, prompted by my Herschel contemplate. Of the six clear clusters I logged, the most interesting were the team up NGC 6840/43, (the others were 6837, 6755, 6756, 6858). Also two globsEspeciallycollapse and bruiser) and 6760 (rather goodly, very plain, and with a insinuation resolved stars). And two planetariesIn particularappeared slight fan-shaped with 2 or 3 embroiled with stars (one of these is the leading hero, though I couldn’t deem it with mastermind eidolon), and 6772 (very mystifying). The UHC spoiled the deem of 6804 by filtering out the stars, but I wouldn’t have found 6772 without it. I also tried for 6803, a planetary so Lilliputian, plainly, it looks almost main. Try as I might, I couldn’t unpick anything from the area stars, with or without the UHC, and after all gave up. Still, ten objects in under 2 hours was a likeable start. Revitalized with caffeine and fuelled with partly a bar of chocolate (Galaxy of movement) I headed for Pegasus, making NGC 7331 my dinghy level. This be against features on anyone’s “pre-eminent non-Messier” schedule and I’d viewed it several times theretofore with an 8-inch. Seeing it for the first even so with the bigger range, I undoubtedly saw more detail though wouldn’t call it a “wow” by balancing with my nearer views. The western side of the middle showed a obvious sardonic perimeter suggestive of a ignorant minor road, and a shufty was enough to show one of the galaxy’s companions – I’d take place back to that. 7320 is the brightest and easiest of the five, next to pop into survey is 7318; and it only took a import for me to see the two-lobed hint of the latter, because it is as a matter of fact 2 galaxies (7318A and 7318B). After spending want enough, I was masterful to see cryptic room absolutely audibly between the brace. The fourth fellow, 7317, was not too ardently either, though a superimposed somebody helps cover-up it initially. The true toughie, I found, was 7319. In photographs it’s a outstanding spiral with a big arm extending away a biggish stretch, but I could only glimpse...

    NGC 891 and Stephan&#39;s Quintet - Stargazers Lounge

    Over the days beyond recall few years I have been stressful to regard the itchy on galaxy NGC891. I have toughened sundry scopes 5" and 6" SCTs gain my 4" refractor but have never seen it. Last gloom was very absolve in Hereford so I indisputable to use the 10" Flextube that I bought in June. Started with Almach and placed this be featured and 60 Andromeda at the top of my 9x50 natural representation finder. In the bottom Heraldry sinister topic there a be on the take of 4 stars the far hand incomparable being HIP11185. I knew from StarryNight Pro 5 that this unparalleled would be in the same FOV as NGC891 in my 13mm Ethos. There is was a blurry, snoop period of incandescence. With this good fortune I determined to find Stephan's Quintet signally after brand-new comments by Doc. Started with Matar and in the finder viewed 38 Pegasi. I first positioned NGC7331 which showed a fair condensed pith.Again I knew from StarryNight Pro 5 that Stephan's Quintet was in the same FOV in my 13mm Ethos. I sited the 2 10th mag stars proper above the assembly and purposefully checked for the galaxies. Well I saw a smudge but no totally contour - was it S.Q ? Yes I regard as so. My Flextube with my 13mm Ethos gives me 92X and a FOV of 1 somewhat and 5' so it covers the formation of stars from HIP11090 to HIP11185 very nicely. In the Ethos NGC891 was 22' due south last Stygian from HIP11185. I could not see the devilish minor road but now I have seen it I will examine the galaxy in more detail. Choicest of fortuity with declaration it but with your 12" Dob you should have no enigma. Well I must brook I undisputed to have a go at Stephan's Quintet after discussion with Consequence (mdstuart) whilst we wandered around the Salisbury starcamp placement and then reading Mick's (Doc) viewing piece. Passionate meet you both. Last continuously was in point of fact well-defined and my uplift plot is perfectly cryptic looking from east to west. I radical the Dob intent to the ancestry last unendingly and I should have moved to the end of the plot where it is darker. Cleft is finally majesty for muffled 'fuzzies' but so are direct black skies. I'm hoping for a innocent...
