[[Black Hat]] has acquired an {{w|H-alpha}} filter. This is a special kind of optical filter used for scientific observations of the Sun's {{w|chromosphere}}. It is different from an ordinary solar filter, which is used to protect one's eyes or camera, as looking at the Sun bare-eyed will do damage to one's eyes. A camera using an ordinary (not H-alpha) solar filter was seen in [[1828: ISS Solar Transit]], and the consequences of not using such a filter were explored in [[2227: Transit of Mercury]].

Before the 1960s, most {{w|airship|airships}} such as blimps and {{w|zeppelin|zeppelins}} used hydrogen as the lifting gas, which resulted in several catastrophic accidents when the highly flammable gas caught fire such as the {{w|LZ 129 Hindenburg|Hindenburg}}. Apparently, Black Hat was not aware that modern blimps use helium instead, and tried to set light to an advertising blimp using fireworks: he could then have used his H-alpha filter to look at the burning hydrogen. (Several companies use blimps for advertising, as they are an unusual and hence enticing sight in the sky, offer a large surface area that can be used to show a slogan or logo, and can stay aloft for a long time with comparatively little cost.) (While modern blimps do use helium, which is an inert gas, Black Hat also should have failed because advertising blimps typically fly higher than firework range, which raises the question of why Black Hat would have suspected that the blimps did not ignite if the fireworks did not reach the blimps. However, it's possible that Black Hat has a way to make fireworks go higher/farther, especially considering Black Hat's sadistic tendencies and the potential for fireworks to be used as weapons.<ref>{{cite web |last1=Wallace |first1=Danielle |title=Crowds launch fireworks at brewery, draw guns on drivers as riots spread from Portland to smaller Oregon city |url=https://www.foxnews.com/us/portland-riots-spread-eugene-oregon-antifa |website=Fox News |access-date=3 July 2021 |date=27 July 2020 |quote=A small Oregon city less than a two-hour drive from Portland experienced rioting Saturday night as hundreds targeted a county jail and federal courthouse with fireworks before attacking businesses downtown while employees remained trapped inside.}}</ref><ref>{{cite web |author1=Artemis Moshtaghian |author2=Eliott C.

In modern times, one of the most well-known uses of airships is blimps for advertising, as they are an unusual and hence attention-getting sight in the sky, offer a large surface area that can be used to show a slogan or logo, and can stay aloft for a long time at comparatively little cost.

Title text: "All the companies whose blimps I shot fireworks at are mad, but MetLife is especially miffed because I dressed up as the Red Baron."

Explanation

Black Hat has acquired an H-alpha filter. This is a special kind of optical filter used for scientific observations of the Sun's chromosphere. It is different from an ordinary solar filter, which is used to protect one's eyes or camera, as looking at the Sun bare-eyed will do damage to one's eyes. A camera using an ordinary (not H-alpha) solar filter was seen in 1828: ISS Solar Transit, and the consequences of not using such a filter were explored in 2227: Transit of Mercury.

Black Hat points out that the filter can also be used to look at nebulae, but doesn't see much further use for it; since the filter only transmits a very narrow bandwidth of light, one generated by hot hydrogen, it is not useful for looking at much else. This gives him an idea, and he leaves.

WARNING!!! A deep sky nebula H-alpha filter has a wider bandwidth than a solar H-alpha filter and WILL hurt the eyes if used to observe the sun!

Upon returning, his hat looks damaged.

I think the first company that got really mad was Goodyear, because they're famous for using blimps.

Additional detail

A H(ydrogen)-Alpha filter is a special lens used for viewing the Hydrogen-Alpha wavelength of light through telescopic or photographic devices. It works by filtering out all wavelengths of light except the red spectral line associated with hydrogen. This is commonly used to see shape and structure of objects that emit said light (namely, our own sun, and various nebulae as mentioned in the text).

Many earlier designs for airships (including the ill-fated Hindenburg) used (highly flammable) hydrogen gas for lift due to both its lower cost and higher availability. After the Hindenburg disaster designers switched exclusively to helium or heated air for lift. I The Hindenberg was supposed to be using Helium, but the USA was the prime producer at that time and for some reason refused to supply Germany at the time. This forced the use of Hydrogen, with the regrettable result. Choice of exterior paint, the gas 'bag' design being too permeable and lack of earthing were also factors. RIIW - Ponder it (talk) 20:27, 3 July 2021 (UTC)

For some reason? Germany was ruled by nazis at the time. Danger Kitty (talk) 21:45, 3 October 2023 (UTC)
At that point, though, there wasn't really that much reason for America to refuse them just for being Nazis (indeed, people like Henry Ford were quite the fans of that regime for an embarressingly long time). If it had been after 1939 (and especially after 1941) then it would have been definitely more than the general politics (or possibly forsightedness?) that it was in the lead up to 1937.
To be exact, in fact, it was the Helium Act of 1925 that banned export (in order to supply the domestic naval vessels of the time, so pro-America rather than anti-Nazi, especially as the Nazi movement wasn't much more than a niche concept in one of various competing factions in that era). The designer had even hoped to get an exception (double-layer the lift-bladders, to use some helium and some hydrogen), but never got that. And then in 1938 there was bartered a deal (having sworn off hydrogen entirely, due to May '37s event) to allow export "only for peaceful purposes", which may have only stopped due to the annexing of Austria (and well before the general "Nazis bad!" message had become the on the ground leftpondian zeitgeist). 141.101.98.175 11:46, 4 October 2023 (UTC)

Metropolitan Life Insurance Company (AKA MetLife) is an insurance company that licensed the Peanuts characters, In particular, Snoopy in their advertising. They featured the Snoopy character in his alter-ego role of World War I Fighter Ace (which frequently fought with the Red Baron in the Charles Schulz comics) in both print and television ads between 1985 and 2016, and most notably pictured on some of their advertising blimps. 162.158.142.160 06:29, 3 July 2021 (UTC) Not the Red Baron

Many nebulae contain excited hydrogen atoms emitting the HΞ± wavelength, so a HΞ± filter is useful for removing other light such as light pollution, making nebulae stand out in photographs.

In most cases when a sun filter is mentioned, it's probably a white-light filter that only reduces the light intensity. A HΞ± filter is used to highlight the sun's chromosphere – the layer above the sun's apparent "surface", the photosphere.

I'm not sure whether the same filters are actually used for photographing both the sun and nebulae. 162.158.183.220 11:52, 3 July 2021 (UTC)

I think someone should edit the summary to detail two points: One, that blimps are not the same as zeppelins. The latter has a rigid body and tanks of gas, rather than the former's balloon body. And two, airships such as the Hindenburg were never designed to be flown using hydrogen; it would have continued to use helium on that one fateful flight if it had not been for a trade embargo on Germany for the gas from its largest supplier, the United States.

I don't believe blimps have really ever been flown with hydrogen, but someone who knows better should add it. 172.69.142.62 20:02, 4 July 2021 (UTC)

About the Warning: i don't think that a filter has the ability, to hurt anyone. Therefore it should be rephrased, that the remaining sunlight will still hurt you eyes. 172.68.110.116 13:10, 5 July 2021 (UTC)

The solar filter in 1828 is surely not a hydrogen-alpha filter. The picture of the sun in that strip doesn't show the deep red hydrogen-alpha color, and it doesn't make sense to set the white balance while using a narrow-band filter. 162.158.134.100 20:08, 10 July 2021 (UTC)
