MrStarGuy SGFT039 overview

  • 1Description

Use Mr. Star Guy's 86-117mm Adjustable Objective White Light Solar Filter to adapt your nighttime refractor telescope to safely view the sun, and on camera lenses without front filter threads or when conventional screw-on filters are unavailable. Outfitted with three thumbscrews for a secure and centered fit, this filter is designed to fit over the entire objective bell so for the correct fit simply measure the outside diameter of the bell — including hardware like retaining rings and screw heads — and choose the size that matches the measurement with some extra room. This model is made to fit objective bells measuring 86-117mm (3.385-4.606").

EN 1836:2005 + A1:2007 certified for safe direct solar viewing, the filter blocks greater than 99.99% of the intense visible white light from the sun plus 100% of harmful ultraviolet (UV) and infrared (IR) radiation. The filter is made of a durable acrylic resin that delivers high-contrast images of the Sun with a neutral color balance revealing the Sun in white, as opposed to the more common red or blue seen when viewing through other solar filters, which restricts bands of the visual spectrum and inhibits clear viewing. The filter housing is made of a lightweight and durable aluminum alloy with a scratch-resistant anodized finish.

    MrStarGuy SGFT039 reviews

    Adjustable Objective White Light Solar Filter (86-117mm OD) is rated 3.5 out of 5 by 17.
    Rated 4 out of 5 by from OK,For the Price 1st; NO Paper information, Like does the wrinkles in the Mylar affect the results? ETC.. 2nd; 86mm really is the minimum, and if the Nylon tip(s) come off probably 90mm would be the minimum,(one came off on mine), so all 3 screws are in all the way and it just barely fits. I will be using this 1 time only in August for the Eclipse, so I'm not fooling with the warranty claim.. The Plastic housing is very good.. I only recommend this because of the price, verses $100+ for quality filters..

    Rated 5 out of 5 by from Works as described I was concerned about the wrinkles in the material until I reasearched it on a few other sites and would that this is normal. Was able to get a good clear image of the sun including some sun spots. Was easy to lock down and take off with the teflon tipped screws

    Rated 5 out of 5 by from Works great to make sun view-able through a telescope! Stretch waves/wrinkles don't seem to make any difference! Picture taken with Celestron NexStar 90 GT, StarGuy filter and D7000.

    Rated 4 out of 5 by from Does the job! I knew that the filter was not the highest quality, but bought it anyway. It is plenty good enough, and priced right. I use it on the 200-500 Nikkor and am careful to only firm the filter using the 3 screw pinch clamps. Very worth the price paid, better clamping is desired. The filtering film itself is great, the small wrinkles are of no concern for solar photography.

    Rated 3 out of 5 by from Flimsy but adequate filter flimsy construction. fits over Sigma 150-500 lens hood, but filter has wavy wrinkles which are hard to get out. However the image of the sun appears to look reasonably good. Adequate for the coming eclipse but could be better..
    Date published: 2017-02-20
    Rated 2 out of 5 by from I would probably chose an alternate solution in the future. The solar film itself was adequate. The overall design of the product has its limitations. The thumb screws are nylon and very tight to screw in and unscrew. For purposes of the eclipse this was problematic because it's important to quickly remove the filter from the camera lens right before the Bailey's Beads and Diamond Ring phases of the eclipse. Because of this I chose to not set the screws, instead choosing to allow the filter to sit loosely on the lens for quick ease of removal. The manner in which the manufacturer packages the filter is also problematic. My initial filter was delivered with abrasions on the film. It was replaced promptly by BH and yet again the second filter had smudges on the films surface. The smudges ultimately did not diminish image quality as far as i can tell.
    Date published: 2017-08-24
    Rated 3 out of 5 by from I had to mount it another way Mine came with Nylon screws that would bind in the plastic housing rendering the mount method useless. I've wrapped the end of my 150-600mm lens with a small microfiber towel and used a rubber band to keep the towel in place. I can then slide the filter on and off over the towel and have a snug fit. The photos through it are very good. I noticed the wrinkles disappeared after being pointed at the sun for a little bit.

    Rated 4 out of 5 by from Not bad , when nylon tips removed from screws . Filter is rather good . On the tips of copper screws there are the nylon tips - Bad idea . Remove nylon things right away , and use screws as intended . To protect the tube , i wrapped some painter tape on the end of tube , underneath the filter . Works OK . Things i dont like : 1) filter gives white colour image of the sun - i know -the sun is actually white , but i hate it . Next time will get the glass filter giving yellow image . My eclipse sun glasses gave 10 times better colour image of the sun . 2) Quality of the make is very so-so . Got to be very careful not to puncture the film . 3) As i mentioned - nylon tips not only useless but even dangerous . Under pressure they bend , slide and prone to loose the grip on the tube . Overall , though , given the fact that its not glass filter , it works OK for limited use .
