Nebula Filter H-Alpha 2-inch 12nm

 

Features

  • High quality Explore Scientific H-Alpha filter
  • Lets only the emission lines of hydrogen "through"
  • Absorbs almost all of the artificial light
  • More contrast and details for all urban astrophotographers
  • Passband bandwidth: 12 nm
  • H-alpha filters can only be used for astrophotography
  • Ideal for use near cities with a slightly brightened sky
  • Also blocks almost all light from mercury and sodium vapor lamps
  • Many of the red glowing emission nebulae are only visible to their full extent on photos with these filters
  • In spite of the existing light pollution, this results in surprisingly good image results

 

In addition to the turbulence in the air, the brightening of the night sky is the greatest obstacle to observing faint objects beyond the solar system. Street lights and other artificial lighting mean that the sky in human settlements is no longer properly black. As a result, the contrast and thus the perception of the deep-sky objects also suffer. Depending on the type of celestial object, however, part of the interfering light can be filtered out, thus making it easier to photograph the objects.

The Explore Scientific H-Alpha filter uses the property of the so-called emission mist. These objects glow in certain colors, the so-called emission lines. The emission lines are linked to certain chemical elements - in this case the red glowing hydrogen. This filter blocks all other colors (and thus almost all artificial light) and only lets through the emission lines of the hydrogen. In particular, the disruptive light from mercury and sodium vapor lamps is effectively blocked. The effect is amazing: Suddenly fog becomes visible in the photos in places that appear completely empty without a filter.

The Explore Scientific H-alpha mist filter has been developed exclusively for astrophotography. Especially when the sky is slightly brightened, many emission nebulae only come to light when this filter is used and are shown in full extent on the astrophotos. The H-alpha nebula filters make astrophotography near cities possible and their use leads to surprisingly good image results despite the existing light pollution. A must for every urban astrophotographer.

The Explore Scientific mist filters are supplied with an individual test report - so you can be sure that you are receiving high-quality filters.

Unbelievable toy for aggressive chewers
Color: Green Cactus
Great toy for aggressive chewers! I'm not one to hand out 5 star reviews but this one I 100% believe in. I bought the first one in 2023 and just replaced it because it broke. Now this is not a played with every once in a while, this was played with daily as it is his favorite toy. Very few toys last long but this one has went beyond my expectations. Could not be happier.

Not Recommended!
Color: Green Cactus
Be aware that with major chewers it is not durable. My dog tour right through it and was eating pieces off of it. Thankfully we got the pieces back out of his mouth but definitely not for tough chewers. Also only lasted 2 days in decent condition and was only used on the occasion throughout the day.

Not strong lasting
Color: Green Cactus
Didn’t even last 3 hours in my house. Too rubbery and our frenchie mix was able to bite pieces off and was trying to eat them. Don’t recommend as a super chewer or consider it durable

Very durable!
Color: Pink Cactus
One of the few actually tough chew toys for dogs who tear apart toys in seconds! My dog loves this thing and has yet to break into the rubber!

Withstands big dog
Color: Green Cactus
As a dog mom to two active pups, I’ve gone through a LOT of chew toys over the years and honestly, many of them just didn’t hold up. Some cracked, broke apart quickly, or became rough after only a short time of chewing. That’s why I was genuinely impressed with the MewaJump chew toy. Both of my dogs immediately loved it, and what stood out most to me was how durable it’s been compared to other toys we’ve tried. It’s held up really well with aggressive chewing while still seeming safe and comfortable for them to use. I also love that it keeps them entertained and engaged longer without constantly worrying about pieces breaking off. Definitely one of the better dog toys we’ve added to our home lately and Molly and Piper would agree.
