Para comenzar en este mundo creo que es suficiente. Facil de usar y montar. A mi hija le ha encantado. Pondr 5 estrellas si creo que lo merece cuando lo pruebe sin contaminacin lumnica.
I got this filter to compare with my other one. The sizing was correct and it did make the image dimmer so I could view more details on the moon’s surface with my telescope. I was fairly happy with it. I actually live very close to a dark sky site so the light pollution in general in my area is still fairly low (I fear that will not last) so I cannot currently attest to the filter’s light pollution reducing capabilities.
This filter works well. It’s super-useful in light-polluted areas so you can get a clearer view of of the moon. It does dim the image a bit, which is good for filtering out nearby lights. The construction is fairly sturdy, and seems like it will last a while.
Also, apparently this listing changed from a filter to a whole telescope, which was somewhat puzzling to me. Just to calm your curiosities, but the filter didn’t do any Pokemon magic and evolve into a telescope–at least, not for me, anyway. But, just to note, I’m writing this for the filter that this used to be and not the telescope.
The Moon and Skyglow Filter screws into the bottom of 1.25″ eye pieces. The listing says the filter transmits only 13 percent of the light. That means that a an overly bright moon is reduced in brightness, so that it is easier to see the details of the craters.
The skyglow aspect of the filter is not quantified, but the name implies that the filter reduces some urban light pollution. Since the filter appears bluish, it is most likely attenuating the light from sodium vapor street lights.
The construction is solid, and the filter does not have any obvious defects. This filter is suitable for aspiring first-time astronomers.
Facile a installer , approche simple pour dbutant dommage que l’article soit arriv avec de nombreux coup sur le.module principal, nanmoins il fonctionne bien on teste ce soir Saturne….par contre voir ds.le temps si le module principal tient la
route vu les chocs qu’il a d subir….alors aprs 7 jours d’essais, TB pour l’observation paysages nature animaux pour le ciel a par la lune le soleil avec filtre , on peut voir quelques plantes mais ca reste frustrant car soit c trop petits malgr le Barlow X2 et ou flou, la stabilit reste difficile, car trpied lger et visserie du materiel loin d’tre suffisante..
Highly recommended!!
This filter is okay really. One night I tested it and it was slightly better than normal (I am in a less light polluted sky than most people). I can’t comment much more as I have repurposed the aluminum frame to hold a different ebay Lazer line filter for the P12 hydrogen line in the Infared.
Note: listing is changed after I acquired product, I am talking about the moon/skyglow filter, not the 80mm telescope.
Yes, but what exactly is it, anyway? It’s a nicely constructed and inexpensive filter that seems to have a slight attenuation at all wavelengths — but selectively more at the yellow end of the spectrum. So, this filter seems to have a slightly purple tint because it’s filtering more of the yellow. But the manufacturer doesn’t specify the optical qualities beyond vague descriptions, and the filter doesn’t come with any instructions.
The description says “The filter effectively filters out selective wavelengths of low-pressure sodium and other man-made sources typically used in street lighting”. But that’s a pretty broad statement and it would be nice to see a spectral response curve. But if it really does target sodium vapor streetlights, then that could be useful.
Sodium vapor streetlights emit at color temperature around 2300 Kelvin and are quite yellow in appearance. So, light scattered from these sources are filtered and this helps to improve the contrast of bright objects such as the moon and planets.
But I don’t know if I’d call it a moon filter — to me, a moon filter is an attenuator that cuts the brightness of the moon so it doesn’t glare. Telescopes can collect too much light from the moon, making it uncomfortable to view.
There’s not much to lose in this filter against light pollution. It didn’t seem to do a whole lot for me. I think it depends on where you are observing from and whether the locality has shifted from sodium vapor to LED street lighting yet. This filter would be less effective at filtering the broader and more blueish spectrum of LED lighting. Sadly — municipalities don’t seem to understand this and are replacing streetlights with overly bright and high color-temperature lighting. This just makes light pollution worse.
So, this filter will probably be more effective for you if you’re surrounded by sodium vapor lights and less so if light pollution is generated by LED lighting. But the filter is nicely made and threaded into my 1 ” eyepieces easily. So, it’s worth a try but don’t expect miracles, it will depend on your situation. I take one star off for no instructions nor detailed optical specifications.
Para empezar y la ms grave no es de focal 600 si no de 500 si es verdad que dimetro es de 80 mm y la ptica y los accesorios son buenos quitando el buscador que es malsimo pero yo lo ped por la focal de 600 y no es as pero bueno por apenas 100 euro que me a costado es aceptable si es verdad que algo de cromatismo tiene a aumentos altos pero nada preocupante es normal en telescopio de esta gama por lo dems ninguna pega entrega en perfectas condiciones y muy bien envalado pero s que deberan corregir lo 600 de focal por qu no es as
Nice double-threaded narrow-band light pollution filter for 1.25″ eyepieces aimed at suppressing reflected sodium light in the atmosphere. Very little light attenuation seen at other wavelengths when looking at a spectrum (this is good!). Has a decidedly purplish tinge (this is normal) that is not shown in the photographs.
My only gripe is that it’s described as a Moon filter, and that this is listed as its first usage (May ’23). Don’t think so. It IS possible that it can add contrast to the Moon’s edge by darkening the sky, but I think this is an incidental feature to its primary purpose (darkening the sky). Regardless, for lunar observation, do yourself a favor and get a proper neutral density filter to couple with this one.
I have sometimes struggled to understand WHAT exactly this filter does. I had seen them before, and wondered, what exactly does it do? And it is not expensive, as some light pollution filters are.
I took it outside tonight with a waxing gibbous Moon of 82%, which is the ideal time to use a filter such as this. Aiming it well away from the Moon at the double star Mizar Alcor in Ursa Major, I flipped the filter between the eyepiece and my eye repeatedly, and did not see any change.
Hmmmm… maybe I needed to be closer to the Moon?
I aimed at a star that was in close proximity to the Moon, but kept the Moon JUST outside the field of view. There was a definite glare from the lunar brightness that was coming through my eyepiece. I flipped this filter between the eyepiece and my eye again – aha! The glare was GONE when the filter was there!
So that’s what this does. Given that there is often a bright Moon out, this filter may provide a bit more observing of some objects in proximity to the Moon. It may not help much away from it, but for the price? It doesn’t hurt to have in an eyepiece kit.
Although most of my eyepieces are the more typical 1.25″, I love the wide field of view and light capturing capacity of my few 2″ eyepieces. Nearly all of my filters are also the more standard 1.25″, so I was pleased to be able to pick up this variable polarizing filter for my bigger lenses at a good price. The variable rotation ring allows you to quickly adjust the amount of light transmission for your target: moon, bright Venus, planet, or nebulae. While I’ve found Neewer to provide the best economy lenses, I’ve been impressed with the quality of the entry level CelticBird filters and this one is no exception. It threaded on cleanly and is now a permanent fixture on my 2″ 28mm eyepiece.
I have a 1.25″ variable polarizing filter, but have a number of 2″ eyepieces for which I’ve never been able to use one, because I hadn’t see a 2″ one previously. This is perfect for them, especially when doing outreach and showing the Moon because people will have a larger field of view to be able to see through a larger eyepiece.
This filter has a very narrow “dark/blackout” range (see video – there’s very little motion from “very dark” to “blackout”) but in most cases that will not be an issue anyway, as something in-between “clear” and “blackout” is going to be appropriate for dimming a bright object.
This is a good filter. Recommended.
I consider a variable polarizing filter to be an essential piece of equipment for the amateur astronomer. It’s by far my most used filter. It’s especially useful for viewing the moon. While I’ve had a 1.25″ polarizing filter for years, I’ve never had a 2″ version. The range of light pass through for this filter is 40% down to 1%. This means that you can really dial down the glare. The build quality is good and the filter works as expected. For the $18.99 price at the time of my writhing this review, it’s a very good deal.
I ordered the 2″ Polarized Pair (2 pieces). They came attached to each other and also have the requisite screw threads. In basic testing I can see the polarizing effect from 0-100%. I look forward to using this on my telescope which has 2″ viewfinder optics. The moon is often so bright at night through a telescope as to cause temporary light blindness, that is, walk away from the scope and being unable to see. The polarizer will allow me to dial down the brightness.
This seems like a nice filter, I have another one that is similar and examined with a strong flashlight it seems comparable in quality.
What I like about this one that that is better than the other is that the two parts can be split to be used individually or both used at different places in the lens stack.
This one is also less than half the price of my other.
