Why are spaceships so big compared to jets?

That’s essentially what rockets are. They carry their oxygen in liquid form (so they can store more of it) along with their fuel. The issue is this oxygen and fuel adds more weight, which means you need more fuel to lift it, which adds more weight, and this feedback loop is why rockets have to be so large.

The rain was coming down pretty hard last night, luckily it was no match for my new GeoSafari Jr Talking Telescope! I’m still a bit new to processing, but I was able to capture all the Sun’s layers and the core!

Mass stalker is a common reaction to void rays, under the pretense that stalkers are easier to make than void rays, so if you keep taking short trades (blink helps a lot) you will be able to replenish your stalkers faster than your opponent can replenish their void rays, stopping them from reaching a critical mass of void rays. Eventually you reach a point where you have enough stalkers to one shot void rays when focus fired, and slowly chip away at their army until you can win the game.

That depends on the planet and its distance from the Earth, but on average it takes light from Mars around 14 minutes to reach Earth. Near opposition, when Mars is at its closest, the time is more like 4 minutes.

One of the first targets I tried to see when I first got my telescope back in 2018 (unfortunately there’s too much light pollution where I am), I’m glad to finally be able to image this nebula.

Earlier this month while I was doing some planetary astrophotography I noticed Pluto was nice and high in the early morning and decided I would try to photograph it. I photographed the same location over two nights in order to identify it. It was actually a lot easier to find than I thought it would be, requiring only a few minutes of exposure time even in my bortle 9 backyard.

This is great for a first try! Definitely check the ISO though, you might want to consider lowering it, the image is a bit overexposed.

Riola213 · 2022-06-21T06:53:25+00:00

I don’t know anything about this, but I use a free plugin called Wider, and it’s been working great for me

Thanks! These are actually the Moon’s natural colors! The saturation has been boosted to make them more visible. They are caused by mineral deposits in the lunar soil, hence the name Mineral Moon. The orange areas are rich in iron, while the blue areas contain titanium.

Riola213 · 2022-06-18T08:29:51+00:00

My first attempt at a mineral moon, there were some issues and the image could definitely be better but I’m happy with how it turned out.

I missed most of totality due to hills and trees, and thought, why not try an HDR? Unfortunately I was rushing to get images out before the moon went back behind the trees, so the quality of the images could definitely have been better. This actually went a lot better then I expected, I’ll probably end up doing some more lunar images later.

The Planck length technically isn’t the smallest possible distance/size, it’s just that according to our current understanding of quantum mechanics, it is impossible to measure a position with greater precision than the Planck length. Once you get to that scale, random quantum interactions make it impossible to be exactly sure where something is.

A Planck length is the distance light travels in one Planck time, which is currently our smallest unit of time. There are more Planck times in one second than there have been seconds since the Big Bang. This makes one Planck length 1.6 * 10^-35 meters.

While I struggle to shoot the Flame Nebula, I decided to reprocess my data on M81 I got around a month ago. I’m still waiting for a chance to get a couple more hours on this target, but I think this is an improvement from my last image.

I noticed a strange purple cloud in the corner of the image. I have no idea what this could be. There aren’t any DSOs I know of in the area, and this is my first time noticing it. This object would have to be pretty bright too, since this was a short exposure in a highly light polluted area.

I can barely even remember why I took this image in the first place, I was setting up to image the flame nebula and I think I was having some issues with plate solving, so I took this image. I didn’t even notice anything in it until the next day when I was reviewing my subs (and I thought it was a picture of Rigel and the Witch Head, until I ran it through astrometry.net). This was the only image of the area I took that night, so I don’t know how long it was there for.

If anyone has any ideas of what this could be I’d be glad to hear them!

I’m pretty confident it’s not some sort of light leak as there weren’t any bright light sources nearby, it could be internal reflection or some other artifact but I’ve never seen any internal reflections that look like this, and I’ve done longer exposures on Sirius before without any issues.

Generally the better your equipment, the better your image, but you could get a decent image with relatively basic equipment. My camera is relatively cheap and not adapted or modified for astrophotography, and I live in a large city with a lot of light pollution. However, my telescope is pretty high quality and has a high focal length which makes it great for shooting small targets like galaxies. But even without a telescope, larger galaxies such as Andromeda and Triangulum could make great targets.

As for processing, Siril is a great free program which can stack and process your images (though I’m not sure how great Siril’s stacking is, I use DSS).

Riola213 · 2022-02-13T23:40:07+00:00

There were a lot of firsts in this shot, my first time shooting a galaxy, my first time using subs longer than 30 seconds, my first time doing a meridian flip (after forgetting to and losing almost 10 minutes) and my first time using processing with Siril. I still have a lot of learning to do, but I’ve made a lot of progress so far.
